Requeriments to compile the kernel

[naeloob]

Hi, this docker lacks bc needed to compile the kernel.
It would be perfect if you add it.
Just
apt install bc

Another thing neeeded to compile the kernel is libc6 (64Bits) :

dpkg --add-architecture amd64
apt update
apt-get install libc6:amd64

This way scripts/mkimage works.

Thanks @naeloob . Could you share what kernel / config / steps to build are you doing so I can reproduce your needs?

[naeloob]

Of course...
The SDK containing the kernel sources 3.18 is this : https://dl.openipc.org/SDK/MStar/MStar-MSC3XX-SDK-toolchain.tgz
I've used your docker to compile busybox, and now i'm trying to compile the kernel.
The instruccions are :

export ARCH = arm
export CROSS_COMPILE = arm-linux-gnueabihf-
make infinity3_defconfig
make clean; make

In the make process of the kernel is required :

• Bc to compile \kernel\time\timeconst.bc -> I've solved with apt install bc
• Libc6 x64 to execute scripts\mkimage, that it's a x64 bin and your docker is based on a x86 ubuntu. I've solved with

dpkg --add-architecture amd64
apt update
apt-get install libc6:amd64

Hope this helps.

Another thing needed is CPIO :
apt-get install cpio

@naeloob can't download MStar-MSC3XX-SDK-toolchain.tgz . Could you provide file or another link?

In the event someone tries to continue this endeavor, it looks like the OpenIPC site reorganized.

OpenIPC download page for MStar: https://openipc.org/cameras/vendors/mstar/socs/msc313e

And provides links for kernel source, buildroot toolchain, and bootloader binary.
