Gentoo Problem Of The Week (#14): Rebuild the World w/ gcc 5.1

Sun May 3 16:57:47 WITA 2015

I’ve set my default compiler to GCC 5.1… This week end I decided to rebuild my installed-packaes w/ it. And, as expected, I’v faced w/ a bunch of problems.

Here is a one of them: GCC 5.x has reviewed -pedantic policy, so libssh wont compile anymore.

In file included from net-libs-libssh-0.6.4/work/libssh-0.6.4/src/agent.c:53:0:
net-libs-libssh-0.6.4/work/libssh-0.6.4/src/agent.c: In function 'ssh_set_agent_channel':
net-libs-libssh-0.6.4/work/libssh-0.6.4/include/libssh/priv.h:200:33: error: ISO C does not support '__FUNCTION__' predefined identifier [-Wpedantic]
     _ssh_set_error(error, code, __FUNCTION__, __VA_ARGS__)

I’ve made an auto-patch (in my repo) to remove that flags and a bug to Gentoo’s bugzilla… hope it wouldn’t be another one wasting of my time.

Another issue was x11-drivers/xf86-video-intel – because of gcc bug. Setting per package options for that package w/ adding -D_FORTIFY_SOURCE=0 works as a workaround.

The next problem happened w/ x11-base/xorg-server: here is a bug in Gentoo’s bugzilla, and here is an explanation of the reason (in section «Preprocessor issues»). I’ve just copied the patch from the bug to my repo of auto-patches to solve this issue.
