I'm seeing this alot, recently. Is there a generic workaround? Something in eclass or profiles that we can do? checking whether <wchar.h> uses 'inline' correctly... no configure: error: <wchar.h> cannot be used with this compiler (x86_64-pc-linux-gnu-gcc -std=gnu99 -O2 -pipe -fomit-frame-pointer ). This is a known interoperability problem of glibc <= 2.5 with gcc >= 4.3 in C99 mode. You have four options: - Add the flag -fgnu89-inline to CC and reconfigure, or - Fix your include files, using parts of <http://sourceware.org/git/?p=glibc.git;a=commitdiff;h=b037a293a48718af30d706c2e18c929d0e69a621>, or - Use a gcc version older than 4.3, or - Don't use the flags -std=c99 or -std=gnu99. Configuration aborted.
While I still think there are some problems in this scenario... Some of my build failures have went away since I recovered from bug 320487 so I'll close this for now.
