Compiling wxMaxima_25.04.0 with GCC-15 on Devuan 5 Daedalus

Portable CMake is available here:
_https://github.com/Kitware/CMake
Portable Ninja is available here:
_https://github.com/ninja-build/ninja
Portable GCC is available here:
_https://github.com/Frogging-Family/mostlyportable-gcc
Portable CMake and Ninja are ready to use.
Portable GCC is easy to compile.

➤ gcc --version
gcc (TkG-mostlyportable) 15.1.1 20250601
➤ g++ --version
g++ (TkG-mostlyportable) 15.1.1 20250601
➤ cmake --version
cmake version 4.0.2
➤ ninja --version
1.12.1

1. Generating the Buildsystem

cmake -S wxmaxima -B build -G Ninja -DCMAKE_BUILD_TYPE="Release" -DCPACK_DEBIAN_PACKAGE_MAINTAINER=Daedalus -DCMAKE_INSTALL_PREFIX='/usr' -DwxWidgets_CONFIG_EXECUTABLE=/usr/bin/wx-config -DWXM_INTERPROCEDURAL_OPTIMIZATION=ON -Wno-dev

2. Compiling with invisible Ninja

cmake --build build

3. Making a Debian package with CPack

cpack --config build/CPackConfig.cmake -G DEB

➤ cpack --config build/CPackConfig.cmake -G DEB
CPack: Create package using DEB

CPack: - Install project: wxMaxima []

➤ ls -1
build

wxmaxima
wxmaxima_25.04.0-1_amd64.deb

➤ tree -L 5 _CPack_Packages

        ├── wxmaxima_25.04.0-1_amd64.deb

            └── usr
                ├── bin
                └── share

➤ dpkg --info wxmaxima_25.04.0-1_amd64.deb | grep Depends
 Depends: libc6 (>= 2.34), libgcc-s1 (>= 3.3.1), libstdc++6 (>= 11), libwxbase3.2-1 (>= 3.2.2+dfsg), libwxgtk-webview3.2-1 (>= 3.2.2+dfsg), libwxgtk3.2-1 (>= 3.2.1+dfsg-2)

These dependencies are very good in the sense that the package can be installed on Devuan 5.
The only problem is that they are wrong. This can be easily verified:

➤ cd _CPack_Packages/Linux/DEB/wxMaxima-25.04.0-Linux/usr/bin
➤ ls
wxmaxima
➤ ./wxmaxima
./wxmaxima: /usr/lib/x86_64-linux-gnu/libstdc++.so.6: version `GLIBCXX_3.4.32' not found (required by ./wxmaxima)
./wxmaxima: /usr/lib/x86_64-linux-gnu/libstdc++.so.6: version `CXXABI_1.3.15' not found (required by ./wxmaxima)

It means that wxMaxima depends on certain libraries compiled together with the portable gcc-15. This problem can be easily fixed, but, first of all, we have to find the cause of the deception.

Debian is deceptive, and, perhaps, fundamentally wrong by design.
We have several hypotheses to verify:
1. The CMake developers do not know the secret esoteric method with which to calculate dependencies.
2. The secret esoteric method is wrong.
3. The Debian "dependency system" is fundamentally wrong.

➤  cd ../../../
➤ ls -1
wxmaxima_25.04.0-1_amd64.deb
wxMaxima-25.04.0-Linux
➤ mkdir debian
➤ ls -1
debian
wxmaxima_25.04.0-1_amd64.deb
wxMaxima-25.04.0-Linux
➤ echo -e "Source: wxmaxima\nPackage: wxmaxima\nDepends: \${shlibs:Depends}" >> debian/control
➤ cat debian/control
Source: wxmaxima
Package: wxmaxima
Depends: ${shlibs:Depends}

dpkg-shlibdeps -v -xwxmaxima --ignore-missing-info -e $(find wxMaxima-25.04.0-Linux -type f 2>/dev/null)

➤ cat debian/substvars
shlibs:Depends=libc6 (>= 2.34), libgcc-s1 (>= 3.3.1), libstdc++6 (>= 11), libwxbase3.2-1 (>= 3.2.2+dfsg), libwxgtk-webview3.2-1 (>= 3.2.2+dfsg), libwxgtk3.2-1 (>= 3.2.1+dfsg-2)

dpkg-shlibdeps produced the same wrong dependencies.

CONCLUSION: The CMake developers are using the same secret esoteric method to calculate dependencies of Debian packages, and this method is wrong.
The method is secret, simply because the system is buggy.
dpkg-shlibdeps cannot be trusted. It is as reliable as weather forecast. Sometimes it is true. Sometimes it is wrong.
The Debian packaging system is either logically inconsistent, or fundamentally wrong by design. This may require a further investigation.

It seems that dpkg-shlibdeps is capable of calculating imaginary esoteric virtual dependencies which are somehow related to the real world dependencies. It might be a product of "demented artificial intelligence", perhaps.

Nevertheless, these dependencies a very good, for they do not prevent installation of the package. The only problem to fix is that of shared libraries. It has a standard solution.

sudo apt install fakeroot patchelf

➤ fakeroot
# mkdir debdir
# ls -1
debdir
debian
wxmaxima_25.04.0-1_amd64.deb
wxMaxima-25.04.0-Linux
# dpkg-deb -R wxmaxima_25.04.0-1_amd64.deb debdir
# patchelf --print-rpath debdir/usr/bin/wxmaxima
   
# patchelf --set-rpath $HOME/.CTools/gcc-15.1.1/lib64 debdir/usr/bin/wxmaxima
# patchelf --print-rpath debdir/usr/bin/wxmaxima
~/.CTools/gcc-15.1.1/lib64
# exit
exit

➤ ./debdir/usr/bin/wxmaxima --version
wxMaxima 25.04.0 (Git version: 583c11f)

➤ cd debdir
➤ mv -v DEBIAN/md5sums ..
renamed 'DEBIAN/md5sums' -> '../md5sums'
➤ fakeroot
# find . -type f -not -path "./DEBIAN/*" -exec md5sum {} + | sort -k 2 | sed 's/\.\/\(.*\)/\1/' > DEBIAN/md5sums
# ls -1 DEBIAN
control
md5sums
# cd ..
# chmod 0644 -- debdir/DEBIAN/md5sums 
# dpkg-deb -b debdir wxmaxima_25.04.0-1_amd64-fixed.deb
dpkg-deb: building package 'wxmaxima' in 'wxmaxima_25.04.0-1_amd64-fixed.deb'.
# exit
exit
➤  cd ..
➤ ls -1 *.deb
wxmaxima_25.04.0-1_amd64.deb
wxmaxima_25.04.0-1_amd64-fixed.deb

Now we can install wxMaxima

sudo dpkg -i wxmaxima_25.04.0-1_amd64-fixed.deb

➤ wxmaxima --version
wxMaxima 25.04.0 (Git version: 583c11f)

How to build portable standalone wxMaxima-25.04.0 and wxMaxima-25.04.0.deb

NOTE: It is "portable standalone" in the sense that it does not require installation.
Just click on it and use. You can also start it from terminal, or create a deskto launcher wxMaxima.desktop

$ ./_CPack_Packages/Linux/DEB/wxMaxima-25.04.0-Linux/usr/bin/wxmaxima --version
wxMaxima 25.04.0 (Git version: 735a94e3a)

wxMaxima 25.04.0 Latest
A bugfix release
https://github.com/wxMaxima-developers/wxmaxima.git

Build dependencies
To build wxMaxima-25.04.0.deb, we need CMake 4.0.1
There is a portable standalone version of CMake 4.0.1 in GitHub.
The manual for it is here:
https://dev1galaxy.org/viewtopic.php?id=7161
You can simply download and unpack it into your home folder, for example:
$ ls -1 $HOME/.CTools/
cmake-4.0.1
meson-1.7.2 
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 
Install "build-essential", build dependencies, etc.:
sudo apt install build-essential debhelper

sudo apt install libwxgtk3.2-dev xvfb netcat-openbsd xauth desktop-file-utils appstream-util libwxgtk-webview3.2-dev libwebkit2gtk-4.0-dev 

sudo apt install fakeroot dpkg-repack git sed tree maxima appstream pandoc po4a imagemagick doxygen texlive-xetex

Clone the source from git:

mkdir wxmaxima2504_build
cd wxmaxima2504_build

git clone https://github.com/wxmaxima-developers/wxmaxima.git

$ ls

Find the "CMakeLists" of the main project:

$ ls ./wxmaxima | grep CMakeLists
CMakeLists.txt

To enable the DEB_config.cmake in the main project, append these lines:

set(CMAKE_MODULE_PATH ${CMAKE_CURRENT_SOURCE_DIR})
include(DEB_config.cmake)

to the end of the file ./wxmaxima/CMakeLists.txt. This can be done with a text editor, or echo command:

$ echo -e '\n\nset(CMAKE_MODULE_PATH ${CMAKE_CURRENT_SOURCE_DIR})\ninclude(DEB_config)' >> ./wxmaxima/CMakeLists.txt

$ tail -3 ./wxmaxima/CMakeLists.txt

set(CMAKE_MODULE_PATH ${CMAKE_CURRENT_SOURCE_DIR})
include(DEB_config)

Enable portable CMake 4.0.1

$ cmake --version
cmake version 3.25.1

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

$ cmake --version
cmake version 4.0.1

1. Generate the Project Buildsystem

cmake -S wxmaxima -B build -DCMAKE_BUILD_TYPE="Release" -DCPACK_DEBIAN_PACKAGE_MAINTAINER=Daedalus -DCMAKE_INSTALL_PREFIX=/usr -DCMAKE_CXX_STANDARD=14 -DCMAKE_CXX_COMPILER=g++ -DwxWidgets_CONFIG_EXECUTABLE=/usr/bin/wx-config -Wno-dev

$ ls -1
