unable to compile a non-gentoo kernel

[Adel Ahmed]

Hello everyone, I'm trying to install gentoo to my galaxy note3 mobile phone.
I have downloaded a stage 3 and setup my chroot, instead of downloading gentoo sources and having to go through all sorts of hell trying to find the kernel patches from samsung ...etc I chose to downlaod a note3 kernel from the internet:
https://github.com/flashka07/android_ke ... msung_ha3g

this is a very old kerenl version(3.4) that requires gcc4 or 3:

Code: Select all

localhost /root/kernel/android_kernel_samsung_ha3g/include/linux # ls *gcc*
compiler-gcc.h   compiler-gcc3.h  compiler-gcc4.h

so i created a symbolic link in this directory called compiler-gcc11.h and had it point to compiler-gcc.h
I can begin the compilation process but it's not long before I get:

Code: Select all

any idea what I should do here?

Have you tried building that kernel with the unmodified files? include/linux/compiler-gcc3.h and include/linux/compiler-gcc4.h only contain less than / greater than [or equal to] GCC version comparisons. I wouldn't touch them unless you are getting an actual build failure which these files are directly responsible of.

[Adel Ahmed]

I tried compiling by linking to gcc3 and gcc4 files but I got the exact same result.

[GDH-gentoo]

I tried compiling by linking to gcc3 and gcc4 files but I got the exact same result.

What did you link to what? Don't do that. Looking at the Git repository, none of the compiler*.h files is a symlink.

[Adel Ahmed]

I used to set compiler-gcc11.h as a symbolic link to compiler-gcc.h, can't even remember why i did that.
I removed the symbolic link anyway and I'm getting the same error

[GDH-gentoo]

Is include/linux/compiler.h (without -gcc ) a symlink? Can you post the output of ls -l /root/kernel/android_kernel_samsung_ha3g/include/linux/compiler*?
