My kernel is building ... after 1h `make` exits with no error

 arghhhhh ... after so much time building all the sources the vmlinux is not created.

 

I did repeat the process after a make clean and an extra hour ... but again no vmlinux 

 

The kernel build process has several steps like creating .o from .c and .h files but then objtool will do an static analysis of the generated object.

 

The problem comes at the end when the biggest vmlinux object must be analyzed with objtool and if options like  CONFIG_DEBUG_INFO the number DWARF data increases and eveything blows.

 

How much memory you'll need ... in my case with a 16GB laptop needed to add swap to allow generate finally the vmlinux .

 

In the image you can see objtool with 79.93% of the memory , so aprox 12GB of ram

End of the Mentorship start of new journey

 The short Mentorship reaches its end , it used to be 6 months long but in this case it was a compressed 3 months one. The experience started with an initial filter based in a very good training available freely in the Linux Foundation site,  I think it worth mention because that Beginners' Guide to Linux Kernel  has everything you need to do your first commit. Even there are others resources in Linux Foundation that are not free, I think this is the only one you need to start.  Then started the real mentorship and the hurry to get your target of at least 5 accepted patches and that's a bit stressful:   first you start with  syzkaller   a great tool leverage from Google to run fuzzy testing. It's a really astonishing thing because give you the kernel and the C code to reproduce the issue ... or it should because not always you get the `reproducer` (how it's called that C code to reproduce the issue) . Check this blog entry for a really good guide on h...

I need a i386 kernel.

 Long time ago everything changed to 64bits for the most common architectures like x86 and arm.  We just don't remember i386 but sometimes we need to build an old 32bits .   What I need to build an i386 (how I did it) The toolchain for the i386 Tell the kernel build system that we want an architecture different from default (which now is 64bits)   That's it , in fact the linux kernel build systems is used to build several different architectures so this exercise is nothing for this beast.   I'll add the commands for my OpenSuse , for other distros it should be very similar sudo zypper in cross-i386-binutils   export ARCH=i386 ;time make LLVM=1 -j$(nproc) all CC='ccache clang'   You can check that the binary is one of 32bits architecture with the file command   $file arch/x86/boot/bzImage arch/x86/boot/bzImage: Linux kernel x86 boot executable, bzImage, version 6.16.0-rc1-dirty (jg@dell) #28 SMP PREEMPT_DYNAMIC Sat Oct ...
