RE: "Devuanite experience"

I have not yet noticed pulseaudio in Recommends. It should not be there. If it is in Recommends, it is automatically installed.
Of course, it can be installed against your will. That is why you have to pin it with a secret esoteric command.

On Devuan, one may still need to have a long list of pinned packages.
There is a conspiracy theory about "Apt’s Best Kept Secret" (a sort of post-esoteric surrealism, perhaps).

Since I am using OSS4 with gstreamer, I have to pin gstreamer1.0-pulseaudio and gstreamer1.0-alsa with the secret command.
Now, they are not going to be installed:

➤ apt-cache policy gstreamer1.0-pulseaudio gstreamer1.0-alsa
gstreamer1.0-pulseaudio:
  Installed: (none)
  Candidate: (none)

➤ apt install clementine --simulate
NOTE: This is only a simulation!

The following NEW packages will be installed:
  clementine liblastfm5-1 libmygpo-qt5-1

⟡ AI Overview
Post-esoteric surrealism refers to the period of surrealism after World War II, where the movement shifted away from the initial emphasis on the unconscious and dreamlike imagery towards a greater focus on the occult and esoteric aspects of art and philosophy. This shift was influenced by the tumultuous events of the war and the subsequent rise of existentialism and other philosophical movements.

There is a secret method with which to calculate the true dependencies of a Debian package.

➤ man dh_shlibdeps | grep DESCRIPTION -A5
DESCRIPTION
       dh_shlibdeps is a debhelper program that is responsible for calculating shared library dependencies
       for packages.

       This program is merely a wrapper around dpkg-shlibdeps(1) that calls it once for each package listed
       in the control file, passing it a list of ELF executables and shared libraries it has found.

Let us try it with the advanced music player for semi-deaf and semi-blind audiphiles:
_https://github.com/strawberrymusicplayer/strawberry/releases/download/1.2.11/strawberry_1.2.11-bookworm_amd64.deb

➤ dpkg --info strawberry_1.2.11-bookworm_amd64.deb | grep Depends -B5
 Package: strawberry
 Version: 1.2.11-bookworm
 Architecture: amd64
 Maintainer: Jonas Kvinge <jonas@jkvinge.net>
 Installed-Size: 13929
 Depends: libasound2 (>= 1.0.16), libc6 (>= 2.34), libcdio19 (>= 2.1.0), libchromaprint1 (>= 1.3.2), libebur128-1 (>= 1.1.0), libfftw3-double3 (>= 3.3.10), libgcc-s1 (>= 3.0), libgdk-pixbuf-2.0-0 (>= 2.22.0), libglib2.0-0 (>= 2.51.0), libgpod4 (>= 0.7.0), libgstreamer-plugins-base1.0-0 (>= 1.0.0), libgstreamer1.0-0 (>= 1.6.0), libicu72 (>= 72.1~rc-1~), libmtp9 (>= 1.1.0), libpulse0 (>= 0.99.1), libqt6concurrent6 (>= 6.1.2), libqt6core6 (>= 6.4.0), libqt6dbus6 (>= 6.4.0), libqt6gui6 (>= 6.3.0), libqt6network6 (>= 6.4.0), libqt6sql6 (>= 6.1.2), libqt6widgets6 (>= 6.3.0), libsqlite3-0 (>= 3.6.11), libstdc++6 (>= 11), libtag1v5 (>= 1.11), libx11-6, libqt6sql6-sqlite, qt6-qpa-plugins, gstreamer1.0-plugins-base, gstreamer1.0-plugins-good, gstreamer1.0-alsa, gstreamer1.0-pulseaudio

What is obviously wrong is the dependency on "gstreamer1.0-alsa, gstreamer1.0-pulseaudio".

Although it is immoral to deceive the deaf, blind, and demented, Linux users are often fooled about pulseaudio dependencies. Therefore, you have to be paranoid and constantly verify the dependencies of Debian packages.

Open the fakeroot console:

➤ fakeroot

# mkdir debdir

# ls -1
debdir  
strawberry_1.2.11-bookworm_amd64.deb

# dpkg-deb -R *.deb debdir

# mkdir debian

# ls -1
debdir
debian
strawberry_1.2.11-bookworm_amd64.deb

# echo -e "Source: strawberry\nPackage: strawberry\nDepends: \${shlibs:Depends}" >> debian/control

# cat debian/control
Source: strawberry
Package: strawberry
Depends: ${shlibs:Depends}

Run "dpkg-shlibdeps" to calculate the true dependencies

# dpkg-shlibdeps -v -xstrawberry --ignore-missing-info -e $(find debdir -type f 2>/dev/null)

The result of calculations is written into debian/substvars

# cat debian/substvars
shlibs:Depends=libasound2 (>= 1.0.16), libc6 (>= 2.34), libcdio19 (>= 2.1.0), libchromaprint1 (>= 1.3.2), libebur128-1 (>= 1.1.0), libfftw3-double3 (>= 3.3.10), libgcc-s1 (>= 3.0), libgdk-pixbuf-2.0-0 (>= 2.22.0), libglib2.0-0 (>= 2.51.0), libgpod4 (>= 0.7.0), libgstreamer-plugins-base1.0-0 (>= 1.0.0), libgstreamer1.0-0 (>= 1.6.0), libicu72 (>= 72.1~rc-1~), libmtp9 (>= 1.1.0), libpulse0 (>= 0.99.1), libqt6concurrent6 (>= 6.1.2), libqt6core6 (>= 6.4.0), libqt6dbus6 (>= 6.4.0), libqt6gui6 (>= 6.3.0), libqt6network6 (>= 6.4.0), libqt6sql6 (>= 6.1.2), libqt6widgets6 (>= 6.3.0), libsqlite3-0 (>= 3.6.11), libstdc++6 (>= 11), libtag1v5 (>= 1.11), libx11-6

Now, with the help of a text editor, you can simply replace the false "Depends" with the true "Depends".

nano debdir/DEBIAN/control

It should look like this:

# cat debdir/DEBIAN/control | grep Depends
Depends: libasound2 (>= 1.0.16), libc6 (>= 2.34), libcdio19 (>= 2.1.0), libchromaprint1 (>= 1.3.2), libebur128-1 (>= 1.1.0), libfftw3-double3 (>= 3.3.10), libgcc-s1 (>= 3.0), libgdk-pixbuf-2.0-0 (>= 2.22.0), libglib2.0-0 (>= 2.51.0), libgpod4 (>= 0.7.0), libgstreamer-plugins-base1.0-0 (>= 1.0.0), libgstreamer1.0-0 (>= 1.6.0), libicu72 (>= 72.1~rc-1~), libmtp9 (>= 1.1.0), libpulse0 (>= 0.99.1), libqt6concurrent6 (>= 6.1.2), libqt6core6 (>= 6.4.0), libqt6dbus6 (>= 6.4.0), libqt6gui6 (>= 6.3.0), libqt6network6 (>= 6.4.0), libqt6sql6 (>= 6.1.2), libqt6widgets6 (>= 6.3.0), libsqlite3-0 (>= 3.6.11), libstdc++6 (>= 11), libtag1v5 (>= 1.11), libx11-6

When dependencies are corrected, you can build the package:

# dpkg-deb -b debdir strawberry_1.2.11-devuan_amd64-fixed.deb
dpkg-deb: building package 'strawberry' in 'strawberry_1.2.11-devuan_amd64-fixed.deb'.

Exit fakeroot console:

# exit
exit

Now, you can install Strawberry with true dependencies:

sudo dpkg -i strawberry_1.2.11-devuan_amd64-fixed.deb

The question remains: what is the origin of pseudo-dependencies in Debian packages?
Obviously, they are man-made rather than naturally produced by invisible magic forces.

Debian packages can be build manually in an old-fashioned way (e.g., with dpkg-deb), without the help of the "debhelper". However, the Debian packaging system is also capable of producing pseudo-dependencies. You can simply add such dependencies into debian/control, for example:

Depends:
 ${shlibs:Depends},
 ${misc:Depends},
 pulseaudio

Then, build the package with "dpkg-buildpackage -us -uc -b". It will produce a Debian package which depends on pulseaudio.

@stopAI

It should be "clearly noticeable", because, the fftrate plugin (if it is correctly configured) replaces ALSA resamplers with the magic fftrate real-time codec.
See also:
_https://dev1galaxy.org/viewtopic.php?id=6593

By the way, have you noticed a secret command "dh_auto_build --list",
and a trick with dpkg-shlibdeps
_https://dev1galaxy.org/viewtopic.php?id=7214

@stopAI

I didn't expect that anyone would be interested in Debian packaging.

Have you tried to compile fftrate?
The updated manual is here:
_https://dev1galaxy.org/viewtopic.php?id=7142
The user manual is here:
_https://dev1galaxy.org/viewtopic.php?id=6644

It will improve sound quality of your pipewire.
You can test it with and without fftrate. The difference should be obvious.
Although, of course, it will be much better without pipewire and pulseaudio.
To disable fftrate, you can simply remove/rename ~/.asoundrc
And, by renaming, you can enable it again.

If you are going to compile X-apps, you may try first to compile XED.
If it works, you may try to compile them all.

igorzwx · Off-topic

@greenjeans

Do you really want to be busy with X-Apps?
You may need to compile a lot of dependencies.
This is what X-Apps are about.
The only X-App which is easy to compile is XED
_https://aur.archlinux.org/cgit/aur.git/tree/PKGBUILD?h=xed-git

XED is very similar to Pluma. You may not need it.

Perhaps, you may better try a sort of WhiteSur (dark theme)

How to compile audacious with muon+samu

Portable static Muon (with embedded samu) is available here:
_https://muon.build/
_https://muon.build/releases/v0.5.0/muon-v0.5.0-amd64-linux
$ file muon-v0.5.0-amd64-linux
muon-v0.5.0-amd64-linux: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), statically linked, BuildID[sha1]=1a2a3022413581300d66c86f02329ed4aa782022, stripped

The procedure of compiling is very similar to that of meson. The main difference is that muon may refuse to search for headers, unless PKG_CONFIG_PATH is set. Although it might be very inconvenient for the slaves of pulseaudio (because of progressive dementia caused by pulseaudio), it provides the freedom to decide which headers should be used.

Dementia is progressive. This means signs and symptoms may be relatively mild at first but they get worse with time. Dementia affects everyone differently, however it can be helpful to think of dementia progressing in 'three stages'.
_https://www.alzheimers.org.uk/about-dementia/symptoms-and-diagnosis/how-dementia-progresses/progression-stages-dementia

⟡ AI Overview
Engaging in intellectually stimulating activities may offer a degree of protection against dementia, particularly for individuals who may have otherwise lower levels of education or occupation. While more research is needed, evidence suggests that activities like reading, playing board games, musical instrument playing, journaling, and crossword puzzles are associated with a reduced risk of developing dementia.

There is a belief that compiling with muon may protect pulseaudio users against Alzheimer's disease (AD). That is why, perhaps, muon is available even in Debian repositories (a very old version, of course).

Because of progressive dementia, it might be necessary to explain how to set PKG_CONFIG_PATH. Otherwise it might be a very difficult problem to solve.

PKG_CONFIG_PATH can be set with a secret command, for example:

export PKG_CONFIG_PATH="$HOME/.local/lib/pkgconfig:$(pkgconf --variable pc_path pkgconf)"

$ cat $HOME/.local/lib/pkgconfig/GL.pc
prefix=/usr
includedir=${prefix}/include
libdir=${prefix}/lib/x86_64-linux-gnu

Name: GL
Description: Legacy OpenGL and GLX library and headers.
Version: 1.2
Libs: -L${libdir} -lGL
Cflags: -I${includedir}/GL

GL.pc is needed for Audacious-plugins (OpenGL Spectrum Analyzer).

The "meson_options.txt" of Audacious and Audacious-plugins can be configured in the same way as it was done for "meson+samu" (see above). Audacious-plugins should be patched, of course (as it was described above). In any case, Audacious should be compiled and installed BEFORE the compilation Audacious-plugins. And, of course, the Debian packages can be made in exactly the same way.

Audacious:

1. Setup the build system

cd audacious
muon setup -Dprefix=/usr -Ddefault_library=shared -Dbuildtype=release build

2. Compile

muon samu -C build

3. Install to a folder "debdir"

cd build
DESTDIR="../../debdir" muon install
cd ../../
install -vDm644 audacious/contrib/audacious.appdata.xml -t "debdir/usr/share/metainfo"
install -vDm644 audacious/COPYING -t "debdir/usr/share/licenses/audacious"

Audacious-plugins:

1. Setup the build system

cd audacious-plugins
muon setup -Dprefix=/usr -Ddefault_library=shared -Dbuildtype=release build

2. Compile

muon samu -C build

3. Install to a folder "debdir"

cd build
DESTDIR="../../debdir" muon install
cd ../../
install -vDm644 audacious-plugins/COPYING -t "debdir/usr/share/licenses/audacious-plugins"

What is:

$ pkgconf --libs --cflags gl
-lGL 
$ pkgconf --libs --cflags GL
Package GL was not found in the pkg-config search path.
Perhaps you should add the directory containing `GL.pc'
to the PKG_CONFIG_PATH environment variable
Package 'GL', required by 'virtual:world', not found

What should be:

$ pkgconf --libs --cflags gl
-I/usr/include/GL -lGL 
$ pkgconf --libs --cflags GL
-I/usr/include/GL -lGL

Otherwise, you may get errors like this:

dependency GL found: NO
OpenGL Spectrum Analyzer: false

A workaround might be obvious, if you do not suffer from dementia.

What might be needed is "/usr/include/" in a sort of 'virtual:path' in the so-called 'virtual:world'. This might be an esoteric problem.
In any case, a simple workaround fixed the problem. Now it looks like this:

dependency GL version: 1.2 found: YES
OpenGL Spectrum Analyzer: true

However, opengl.pc might also be wrong:

$ pkgconf --libs --cflags opengl
-lOpenGL

It seems that "gtk+-3.0" was already fixed:

$ pkgconf --libs --cflags gtk+-3.0
-I/usr/include/gtk-3.0 -I/usr/include/pango-1.0 -I/usr/include/glib-2.0 -I/usr/lib/x86_64-linux-gnu/glib-2.0/include -I/usr/include/harfbuzz -I/usr/include/freetype2 -I/usr/include/libpng16 -I/usr/include/libmount -I/usr/include/blkid -I/usr/include/fribidi -I/usr/include/cairo -I/usr/include/pixman-1 -I/usr/include/gdk-pixbuf-2.0 -I/usr/include/x86_64-linux-gnu -I/usr/include/gio-unix-2.0 -I/usr/include/GL -I/usr/include/atk-1.0 -I/usr/include/at-spi2-atk/2.0 -I/usr/include/at-spi-2.0 -I/usr/include/dbus-1.0 -I/usr/lib/x86_64-linux-gnu/dbus-1.0/include -pthread -lgtk-3 -lgdk-3 -lz -lpangocairo-1.0 -lpango-1.0 -lharfbuzz -latk-1.0 -lcairo-gobject -lcairo -lgdk_pixbuf-2.0 -lgio-2.0 -lgobject-2.0 -lglib-2.0

How to compile Audacious-plugins

sidplay-rom-paths.patch is available here:
_https://gitlab.archlinux.org/archlinux/packaging/packages/audacious-plugins/-/raw/main/sidplay-rom-paths.patch

Download the source code and the patch

mkdir Build1p
cd Build1p
git clone https://github.com/audacious-media-player/audacious-plugins.git --depth 1

$ ls -1
audacious-plugins
sidplay-rom-paths.patch

Apply the patch:

cd audacious-plugins
patch -Np1 -i ../sidplay-rom-paths.patch
cd ..

Edit "meson_options.txt" with a text editor

nano audacious-plugins/meson_options.txt

Disable QT6, enable OSS4 (if it is installed), disable pulse and unwanted resamplers. For example:

# GUI toolkits
option('qt', type: 'boolean', value: false,

# output plugins
option('oss4', type: 'boolean', value: true,
       description: 'Whether OSS4 support is enabled')
       
option('pipewire', type: 'boolean', value: false,
option('pulse', type: 'boolean', value: false,
option('qtaudio', type: 'boolean', value: false,

option('resample', type: 'boolean', value: false,
option('soxr', type: 'boolean', value: false,
option('speedpitch', type: 'boolean', value: false,

1. Setup the build system

Description: samurai is a ninja-compatible build tool written in C99 
 • with a focus on simplicity, speed, and portability.
 • samurai implements the ninja build language through version 1.9.0 except for MSVC dependency handling (deps = msvc).
 • It uses the same format for .ninja_log and .ninja_deps as ninja, currently version 5 and 4 respectively.
 • It is feature-complete and supports most of the same options as ninja.

Create Debian source package

dpkg-source -b .

Build Debian binary package (deb)

dpkg-buildpackage -us -uc -b

$ ls -1 ../*.deb

If you enjoy it, you may say thanks to the creator of the magic fftrate codec, Sergei Petrov.

There is a belief that fftrate may cure deafness. It may not always work. If it does not, the victims of pulseaudio may not have any chance to regain hearing loss. It seems impossible to cure deafness: "there are no known treatments to restore hearing, because auditory hair cells in mammals, unlike those in birds or fish, do not regenerate once lost."

There might be obstacles on the road to freedom. You may get problems like this:

$ dpkg-buildpackage -b
...
fatal error: toml++/toml.hpp: No such file or directory
    2 | #include "toml++/toml.hpp"

To overcome this obstacle you can simply borrow "toml++/toml.hpp" from Debian testing and compile the package you need on Devuan stable. For some strange reason, this method usually works.

You can find "toml++/toml.hpp" in a Debian (testing=trixie) package:

Package: libtomlplusplus-dev (3.4.0+ds-0.2 and others)
_https://packages.debian.org/trixie/libtomlplusplus-dev

$ tree -L 4 libtomlplusplus-dev_3.4.0+ds-0.2+b1_amd64

        │   └── libtomlplusplus-dev
        └── doc-base
            └── libtomlplusplus-dev.tomlplusplus

You can download this package, and extract "usr" to a folder like this:

$HOME/.CTools/LIBS/
$HOME/.CTools/LIBS/usr/include/toml++/toml.hpp

Then you can add "$HOME/.CTools/LIBS/usr/include" to $CPLUS_INCLUDE_PATH

The secret knowledge is here:
_https://gcc.gnu.org/onlinedocs/cpp/Environment-Variables.html

It is very simple:

$ echo $CPLUS_INCLUDE_PATH
                           # It is empty

$ export CPLUS_INCLUDE_PATH="$HOME/.CTools/LIBS/usr/include"

Verify the INCLUDE_PATH for g++ with a secret command:

echo | gcc -Wp,-v -xc++ - -fsyntax-only

$ echo | gcc -Wp,-v -xc++ - -fsyntax-only
ignoring duplicate directory "/usr/include/x86_64-linux-gnu/c++/12"
ignoring nonexistent directory "/usr/local/include/x86_64-linux-gnu"
ignoring nonexistent directory "/usr/lib/gcc/x86_64-linux-gnu/12/include-fixed"
ignoring nonexistent directory "/usr/lib/gcc/x86_64-linux-gnu/12/../../../../x86_64-linux-gnu/include"
#include "..." search starts here:
#include <...> search starts here:

 /home/<YOUR USER NAME>/.CTools/LIBS/usr/include
 /usr/include/c++/12
 /usr/include/x86_64-linux-gnu/c++/12

 /usr/lib/gcc/x86_64-linux-gnu/12/include
 /usr/local/include
 /usr/include/x86_64-linux-gnu
 /usr/include
End of search list.

Now everything works. The "fatal error" had gone away.

The question remains: why does this method work. It looks like they do not update software on Debian stable. They have restricted resources, and, of course, they have to fix problems caused by systemd, pipewire and pulseaudio.

Knowledge and ignorance—
a man who knows them both together,
Passes beyond death by ignorance,
and by knowledge attains immortality.
Isha Upanishad, Verse 12

The road to freedom is short and straightforward. Read PKGBUILs of AUR packages, and do the same on Devuan.

It doesn't always work. Sometimes it is much better with Debian sources, if you know the secret commands. Debian packaging is a sacred ritual, not a secular one. It requires initiation into secret knowledge. If you are not initiated, you are doomed to dwell in ignorance and doubt. In essence, initiation is a rite of passage marking entrance into a sort of esoteric society. In particular, it signifies a transformation in which the initiate is 'reborn' into a new role.

Step 1: Install a secret package

sudo apt-get install packaging-dev

Step 2: Download the source you need. For example:

Debian testing (Trixie)
_https://packages.debian.org/source/testing/gnuplot
Source Package: gnuplot (6.0.2+dfsg1-1)
Debian Package Source Repository (Browsable)
https://salsa.debian.org/science-team/gnuplot 

mkdir BUILD_GIT

cd BUILD_GIT

git clone https://salsa.debian.org/science-team/gnuplot.git --depth 1

$ ls
gnuplot

$ du -sh *
17M	gnuplot

Step 3: Install "Build-Depends"

cd gnuplot

mk-build-deps

$ ls *.deb
gnuplot-build-deps_6.0.2+dfsg1-1_all.deb

Install gnuplot-build-deps*.deb

sudo dpkg -i gnuplot-build-deps_6.0.2+dfsg1-1_all.deb

You may notice a problem:

$ sudo dpkg -i gnuplot-build-deps_6.0.2+dfsg1-1_all.deb
...
dpkg: error processing package gnuplot-build-deps (--install):
 dependency problems - leaving unconfigured

Fix it with a magic command:

sudo apt -f install

It may remove "emacs-gtk" and install "emacs-nox" instead. You can reinstall it later, or remove them both.

_https://youtu.be/ugFtz7XOOWU?t=25s

$ mv -v gnuplot-build-deps_6.0.2+dfsg1-1_all.deb ../

Step 4: Prepare the source

Execute secret commands:

export QUILT_PATCHES=debian/patches

quilt push -a

The output on terminal should look like this:

$ quilt push -a
Applying patch 04_fix_libexecdir.diff
patching file src/Makefile.am
...
Applying patch 50_no-webp_figures-in-documentation.patch
patching file docs/Makefile.am

Now at patch 50_no-webp_figures-in-documentation.patch

Step 5: Build GnuPlot

dpkg-buildpackage -b

$ ls -1 ../*.deb
../gnuplot_6.0.2+dfsg1-1_all.deb
../gnuplot-build-deps_6.0.2+dfsg1-1_all.deb
../gnuplot-data_6.0.2+dfsg1-1_all.deb
../gnuplot-doc_6.0.2+dfsg1-1_all.deb
../gnuplot-nox_6.0.2+dfsg1-1_amd64.deb
../gnuplot-nox-dbgsym_6.0.2+dfsg1-1_amd64.deb
../gnuplot-qt_6.0.2+dfsg1-1_amd64.deb
../gnuplot-qt-dbgsym_6.0.2+dfsg1-1_amd64.deb
../gnuplot-x11_6.0.2+dfsg1-1_amd64.deb
../gnuplot-x11-dbgsym_6.0.2+dfsg1-1_amd64.deb

Step 6: Install GnuPlot

cd ../
sudo dpkg -i gnuplot_6.0.2+dfsg1-1_all.deb gnuplot-data_6.0.2+dfsg1-1_all.deb gnuplot-qt_6.0.2+dfsg1-1_amd64.deb

Step 7: Test

You can test GnuPlot with Maxima

$ maxima

(%i1) plot2d([tanh(20*sin(x))], [x,-10*%pi,10*%pi], [y,-1.1,1.1], [plot_format, gnuplot])$

(%i3) quit();

You can export plots from GnuPlot window to SVG format. It works with gnuplot-qt
Click on "Export" icon (the top left corner of GnuPlot window), and select "Export to SVG" in drop down menu.

Some bugs become visible, if you try a dark theme for wxMaxima worksheets.
A workaround is to disable "Intelligently hide cell brackets"
wxMaxima → Edit → Configure → Worksheet: 
Disable (uncheck) "Intelligently hide cell brackets" 
You may also try:
wxMaxima → View → "Invert worksheet brightness" 

wxMaxima is a GUI for maxima. If maxima fails to work (as it usually happens on Fedora), wxMaxima does not react on maxima commands (e.g., 1 + 1). The Fedora users, of course, cannot understand what is going on. This is, largely because, perhaps, there are pipewire/pulseaudio users.
You may want to test maxima before testing wxMaxima. To open Maxima Shell, type the command maxima in the command-line terminal.

Perhaps, mathematical knowledge may help to understand the problems of digital sound processing (e.g., resampling), but it may not liberate from ignorance. The cult of pulseaudio is a sort of Cargo cult, and therefore, it is doomed to persist despite any failures to materialize utopian dreams. If the particular "advanced projects" failed, the ends are still valid, and the dream as a vehicle of truth stays unimpaired. The "myth-dream" of the cult is, in essence, a self-generating "objective truth". The "myth-dream" of "advanced Linux sound system" will inevitably produce new sorts of pulseaudio/pipewire and other "advanced crap". The problem is that such myths generate the true knowledge which emerges as an imperative to action. The Cargo cult persists because it fails to fulfill its ends. The cult of systemd is the same thing.

In the context of Cargo the myth-dream is truth, and, moreover, the several truths contained in the myth-dream emerge as imperatives. Ideally, the task of the charismatic figure can be seen as an attempt to realize these imperatives in action. (Kenelm Burridge, Mambu (1960). pp. 249-250).

One may want to install the "DevelopmentSnapshot" of wxMaxima, because the "stable versions" of wxMaxima (available in Devuan/Debian repositories) are so buggy that they are impossible to use.

The "DevelopmentSnapshot" of wxMaxima seems to work on Devuan 5 Daedalus. It looks usable, although, of course, there still a lot of bugs.

The package of wxMaxima (DevelopmentSnapshot) is available in Arch Linux AUR repository:
_https://aur.archlinux.org/packages/wxmaxima
_https://aur.archlinux.org/cgit/aur.git/tree/PKGBUILD?h=wxmaxima

Therefore, it is not difficult to build a Debian package of the "DevelopmentSnapshot".

Description: GUI for the computer algebra system Maxima
 wxMaxima is a graphical user interface for the computer algebra system
 Maxima. It eases the use of Maxima by making most of its commands available
 through a menu system and by providing input dialogs for commands that
 require more than one argument. It also implements its own display engine
 that outputs mathematical symbols directly instead of depicting them with
 ASCII characters.
 .
 wxMaxima also features 2D and 3D inline plots, simple animations, mixing of
 text and mathematical calculations to create documents, exporting of input
 and output to TeX, and a browser for Maxima's manual including command index
 and full text searching.

dpkg-repack

DESCRIPTION
       dpkg-repack creates a .deb file out of a Debian package that has already been installed on your system.

       If any changes have been made to the package while it was unpacked (e.g.  conffiles files in /etc modified),
       the new package will inherit the changes.  (There are exceptions to this, including changes to configuration
       files that are not conffiles, including those managed by ucf(1).)

       This utility can make it easy to copy packages from one computer to another, or to recreate packages that are
       installed on your system, but no longer available elsewhere.

       Note: dpkg-repack will place the created package in the current directory.

It can create a Debian package from the installed one (e.g. wxMaxima)

$ dpkg -l | grep wxmaxima
ii  wxmaxima      25.01.0-1     amd64     GUI for the computer algebra system Maxima

$ fakeroot -u dpkg-repack wxmaxima
dpkg-deb: building package 'wxmaxima' in './wxmaxima_25.01.0-1_amd64.deb'.

$ ls
wxmaxima_25.01.0-1_amd64.deb

Extract "control-information" from the package:

$ dpkg-deb -e wxmaxima_25.01.0-1_amd64.deb

$ ls -1

There is a belief that knowledge liberates from ignorance. Perhaps, wxMaxima may help semi-deaf Linux users to understand something about resampling and the Gibbs phenomenon. Although, of course, mathematics might be a problem, because pulseaudio is likely to damage the brain in a severe and irreversible manner. Hearing loss and dementia are doomed to follow.

Source: wxmaxima
Build-Depends: debhelper-compat (= 13), cmake (>= 3.4) | cmake3, libwxgtk3.2-dev, xvfb, netcat-openbsd, xauth, desktop-file-utils, appstream-util, libwxgtk-webview3.2-dev

To build wxmaxima (24.02.1-1), we need cmake (>= 3.4).

$ cmake --version
cmake version 3.25.1

CMake v4.0.1

https://github.com/Kitware/CMake/releases/tag/v4.0.1

Download portable CMake v4.0.1:

https://github.com/Kitware/CMake/releases/download/v4.0.1/cmake-4.0.1-linux-x86_64.tar.gz

$ ls
cmake-4.0.1-linux-x86_64.tar.gz

mkdir -v $HOME/.CTools

tar -zxvf cmake*.tar.gz -C $HOME/.CTools

$ ls $HOME/.CTools
cmake-4.0.1-linux-x86_64

mv $HOME/.CTools/cmake-4.0.1-linux-x86_64 $HOME/.CTools/cmake-4.0.1

$ ls $HOME/.CTools/
cmake-4.0.1

$ ls -1 $HOME/.CTools/cmake-4.0.1
bin
doc
man
share

You can open a file manager in the cmake folder and investigate the content

caja $HOME/.CTools/cmake-4.0.1

How to use portable CMake v4.0.1

export PATH="$HOME/.CTools/cmake-4.0.1/bin:$PATH"

$ cmake --version
cmake version 4.0.1

Install compilers, build dependencies, etc.:

sudo apt install build-essential debhelper libwxgtk3.2-dev xvfb netcat-openbsd xauth desktop-file-utils appstream-util libwxgtk-webview3.2-dev

You may want to install devscripts and a sort of AI assistant:

sudo apt install devscripts command-not-found

sudo update-command-not-found

EXAMPLES:

$ mmk-build-deps
Command 'mmk-build-deps' not found, did you mean:
  command 'mk-build-deps' from deb devscripts
Try: sudo apt install <deb name>

$ gbp
Command 'gbp' not found, but can be installed with:
sudo apt install git-buildpackage

Now we can build wxMaxima.

$ ls -1
wxmaxima_24.02.1-1.debian.tar.xz
wxmaxima_24.02.1-1.dsc
wxmaxima_24.02.1.orig.tar.gz
wxmaxima_24.02.1.orig.tar.gz.asc

Unpack the source:

dpkg-source -x *.dsc

$ ls -1
wxmaxima-24.02.1
wxmaxima_24.02.1-1.debian.tar.xz
wxmaxima_24.02.1-1.dsc
wxmaxima_24.02.1.orig.tar.gz
wxmaxima_24.02.1.orig.tar.gz.asc

Change to the source directory:

cd wxmaxima-24.02.1

$ cmake --version
cmake version 3.25.1

export PATH="$HOME/.CTools/cmake-4.0.1/bin:$PATH"

$ cmake --version
cmake version 4.0.1

We have all the dependencies needed to build wxMaxima.
But, formally, the "Build-Depends" are not satisfied.
Therefore, we have to use -d flag to override the default checking procedure.

Verify whether the terminal prompt is in the source directory:

$ pwd
/home/.../Builds/Build_wxmaxima_24.02.1-1/wxmaxima-24.02.1

Build wxMaxima (use -d flag to override):

LibreOffice vs OpenOffice
The Clear Choice
By Bruce Byfield
While LibreOffice and OpenOffice have a shared past, LibreOffice outstrips OpenOffice in contributors, code commits, and features.
A search for comparisons of LibreOffice and Apache OpenOffice returns over 8.3 million results. That number comes as no surprise, given that LibreOffice and OpenOffice are the best-known open source office suites and share a common past. However, what is surprising is how shallow many of those comparisons are. Many offer only a superficial glimpse at either office suite from the viewpoint of an unsophisticated and undemanding user. Often, the comparisons are obsolete. Even more importantly, many comparisons strive for a false sense of objectivity by declaring that any differences are minor. However, by every possible standard, LibreOffice outshines OpenOffice and shows OpenOffice to be outdated. To pretend otherwise is a distortion of the truth.

There is a standard method with which to modify Debian packages.
We can use it to remove strange dependencies of strawberry_1.2.9-bookworm_amd64.deb (github)
_https://github.com/strawberrymusicplayer/strawberry/releases/tag/1.2.9

_https://github.com/strawberrymusicplayer/strawberry
Strawberry is a music player and music collection organizer. It is a fork of Clementine released in 2018 aimed at music collectors and audiophiles.

It is aimed at audiophiles in the sense, perhaps, that it depends on gstreamer1.0-pulseaudio. There is a common belief that Linux users, in general, and Linux audiophiles, in particular, tend to be semi-deaf and semi-blind, and, therefore, they want to use pulseaudio and all sorts of equalizers, amplifiers, and DACs to enhance high frequencies.

Why are high frequency sounds typically the first to go in hearing loss?

gstreamer1.0-alsa, gstreamer1.0-pulseaudio are, of course, pseudo-dependencies. They are not real dependencies in the sense that they can be safely removed.

Strawberry player is simply a GUI for GStreamer, and nothing more. Regardless of what you think GStreamer is, it does not depend on its plugins. It should be obvious that GStreamer plugins depend on GStreamer and not other way round.

There is a reason, of course, why the GStreamer package is split into "libgstreamer" and "plugins". If you have not been initiated into the secret knowledge of GStreamer, you may try to read its documentation
_https://gstreamer.freedesktop.org/documentation/installing/on-linux.html

ALSA users may want to install gstreamer1.0-alsa.
OSS4 users may want to remove gstreamer1.0-alsa, in order to use GStreamer based media players (e.g. Totem, Parole, and the like) with OSS4.

NOTE: ALSA users are recommended to install "gstreamer1.0-alsa". Otherwise, GStreamer may use "openalsink" with ALSA.
_https://gstreamer.freedesktop.org/documentation/openal/openalsink.html

It is not difficult to correct dependencies of a Debian package.

Install fakeroot

sudo apt install fakeroot

$ ls
strawberry_1.2.9-bookworm_amd64.deb

Open fakeroot console and execute mkdir debdir:

$ fakeroot
# mkdir debdir

# ls -1
debdir
strawberry_1.2.9-bookworm_amd64.deb

Unpack the deb package to debdir

# dpkg-deb -R *.deb debdir

# ls -1 ./debdir

usr

# ls -1 ./debdir/DEBIAN
control
md5sums

# file ./debdir/DEBIAN/control
./debdir/DEBIAN/control: ASCII text, with very long lines (784)

Remove unwanted dependencies with a text editor:

# nano ./debdir/DEBIAN/control
Unable to create directory /root/.local/share/nano/: Permission denied
It is required for saving/loading search history or cursor positions.

You may have noticed that nano is complaining about missing root privileges.
This is because "fakeroot" is not a real "root", as the name suggests.
Such complaints can be safely ignored.

You can also rename a Debian package, change version, add scripts to debdir/usr/bin, and so on.
Notice that it is immoral (and illegal) to insert malware into Debian packages.

To debug Strawberry, you can simply start it from terminal.
