2.6.x Kernel Compilation Problems
With Ubuntu 12 is no longer possible to build old 2.6 kernels (2.6.30 in my case). The problem is that gcc 4.6 doesn't support anymore linker-style architecture options.
PROBLEM:
gcc: error: elf_i386: No such file or directory
OBJCOPY arch/x86/vdso/vdso32-int80.so
objcopy: 'arch/x86/vdso/vdso32-int80.so.dbg': No such file make[2]: *** [arch/x86/vdso/vdso32-int80.so] Error 1 make[1]: *** [arch/x86/vdso] Error 2 make: *** [arch/x86] Error 2
SOLUTION:
Apply the following changes to solve the problem :
In arch/x86/vdso/Makefile :
replace "-m elf_x86_64" by "-m64" on the line starting with VDSO_LDFLAGS_vdso.lds replace "-m elf_i386" by "-m32" on the line starting with VDSO_LDFLAGS_vdso32.lds
