Building dev-util/strace-4.13 (any version really) will fail saying: In file included from ./defs.h:42:0, from mpers-m32/struct_blk_user_trace_setup.c:29: /usr/lib/gcc/x86_64-gentoo-linux-musl/4.9.4/include/stddef.h:212:23: error: conflicting types for 'size_t' typedef __SIZE_TYPE__ size_t; ^ In file included from /usr/include/sys/types.h:57:0, from ./defs.h:40, from mpers-m32/struct_blk_user_trace_setup.c:29: /usr/include/bits/alltypes.h:101:24: note: previous declaration of 'size_t' was here typedef unsigned _Addr size_t; ^ In file included from ./defs.h:42:0, from mpers-m32/struct_blk_user_trace_setup.c:29: /usr/lib/gcc/x86_64-gentoo-linux-musl/4.9.4/include/stddef.h:324:24: error: conflicting types for 'wchar_t' typedef __WCHAR_TYPE__ wchar_t; ^ In file included from /usr/include/inttypes.h:12:0, from ./defs.h:39, from mpers-m32/struct_blk_user_trace_setup.c:29: /usr/include/bits/alltypes.h:18:13: note: previous declaration of 'wchar_t' was here typedef int wchar_t; ^
Just to add to this, commenting out the offending lines in GCC's stddef.h lets strace build.

This disagreement only occurs on older versions of GCC: 01:10 < smaeul> ryao: ahh, I'm using gcc 5.4.001:10 < smaeul> it has #define __WCHAR_TYPE__ int 01:11 < smaeul> and #define __SIZE_TYPE__ long unsigned int 01:11 < smaeul> which matches musl 01:12 <+ryao> smaeul: Nice, so I just need to switch to a newer GCC... I had been sticking with the stable version.

The only gcc-4.9 ebuild with the fix for this is gcc-4.9.3-r999.ebuild from the musl overlay. This ebuild uses the gcc patches also used by other distributions. There were however some other problems with this approach.

I'm hoping to jump from the overlay to gcc-6 in tree once its stabilized. That may be a while.
As we no longer support <sys-devel/gcc-6 we can close this
