Bug 69265 – dietlibc-0.26, used by genkernel 3.1.0a, can't build on a ppc system

• Status: VERIFIED TEST-REQUEST
• Product: Gentoo Linux

[Description Olivier Castan 2004-10-28 07:08:44 UTC]

This is due to a redefinition of the same structure (pt_regs) between 2 include files :
include/asm/sigcontext.h
and include/sys/ptrace.h


Reproducible: Always
Steps to Reproduce:
#genkernel all
[...]
gcc -I. -isystem include -fno-stack-protector -D__dietlibc__ -c lib/__ptrace.c -o bin-ppc/__ptrace.o
In file included from include/asm/sigcontext.h:25,
                 from include/sys/ucontext.h:4,
                 from include/signal.h:543,
                 from include/sys/select.h:5,
                 from include/unistd.h:8,
                 from lib/__ptrace.c:8:
include/asm/ppc-sigcontext.h:2: erreur: red

Actual Results:  
Build failure

Expected Results:  
Copy patch from
http://www.hu.kernel.org/pub/linux/libs/dietlibc/dietlibc-0.26-0.27.diff
which replace everything between "#elif defined(powerpc) || defined
(__powerpc64__)" and "#elif defined(__hppa__)" with "#include <asm/sigcontext.h>"

Or upgrade to dietlibc-0.27 in genkernel

Try latest genkernel, that has 0.27...
