[SOLVED] modprobe ikconfig -> FATAL: Module ikconfig not found in directory

Hi,

I've cross-compiled a Linux kernel https://github.com/raspberrypi/linux (6.6.63)

with

CONFIG_IKCONFIG=m
CONFIG_IKCONFIG_PROC=y

but when I do modprobe ikconfig on the client, I get:

FATAL: Module ikconfig not found in directory /lib/modules/6.6.63-v8_TESTT+

I've launched depmod but the error remain.

tree -F -L 2 /lib/modules/6.6.63-v8_TESTT+

|-- build -> /tmp/RaspKernel6-6y/linux
|-- kernel/
|   |-- arch/
|   |-- crypto/
|   |-- drivers/
|   |-- fs/

|-- modules.dep
|-- modules.dep.bin
|-- modules.devname
|-- modules.order
|-- modules.softdep
|-- modules.symbols
`-- modules.symbols.bin

I don't know if /lib/modules/6.6.63-v8_TESTT+/build is required to load the module, as /tmp/RaspKernel6-6y/linux was actually in the host (cross-compile) and not on the raspberry..

Here the ~commands that I use to cross-compile the kernel

su
apt install bc bison flex libssl-dev make libc6-dev libncurses5-dev crossbuild-essential-arm64

cd /tmp/LinuxKernel/linux

git clone --depth=1 --branch rpi-6.6.y https://github.com/raspberrypi/linux

## applying the default configuration
cd linux
KERNEL=kernel8
make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- bcm2711_defconfig
##

make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- menuconfig

make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- Image modules dtbs

## install the kernel modules onto the boot media:
env PATH=$PATH make -j12 ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- INSTALL_MOD_PATH=/mnt/rasprootfs modules_install

cp arch/arm64/boot/Image /mnt/raspboot/$KERNEL.img
cp arch/arm64/boot/dts/broadcom/*.dtb /mnt/raspboot/
mkdir /mnt/raspboot/overlays
cp arch/arm64/boot/dts/overlays/*.dtb* /mnt/raspboot/overlays/
cp arch/arm64/boot/dts/overlays/README /mnt/raspboot/overlays/

If you have any ideas, I'm all ears..

Re: [SOLVED] modprobe ikconfig -> FATAL: Module ikconfig not found in directory

I recompiled the kernel with that change

CONFIG_IKCONFIG=m y
CONFIG_IKCONFIG_PROC=y

but still get

FATAL: Module ikconfig not found in directory /lib/modules/6.6.63-v8_TESTT+

😓

Re: [SOLVED] modprobe ikconfig -> FATAL: Module ikconfig not found in directory

any ideas

Only the obvious: Read the documentation (or a good wiki). The module this option builds is not named 'ikconfig'.

And the blindingly obvious:

CONFIG_IKCONFIG=m y

Selecting 'y' will build the option into the kernel image, so there definitely won't be a module to load.

Aside, no idea why you would want IKCONFIG as a module anyway. There's sod-all to be saved by not including a copy of .config in the kernel, so you might as well build it in.

Once is happenstance. Twice is coincidence. Three times is enemy action. Four times is Official GNOME Policy.

Thanks steve_v

indeed trying to activate it (modprobe) as it's no longer a module, will definitly not work.

I've tried a zless /etc/config.gz and it works so recompiling the kernel worked
