Martin, what's the best way to fix this? I built XFree86 on my Linux system today, and did NOT have this problem. Everything is fine. The symbols defined by xmkmf are: checking for X defines extracted by xmkmf Defining NARROWPROTO Defining linux Defining __i386__ Defining _POSIX_SOURCE Defining _BSD_SOURCE Defining _SVID_SOURCE However, in xc/config/cf/linux.cf, I see: #if LinuxCLibMajorVersion >= 6 #define LinuxSourceDefines -D_POSIX_C_SOURCE=199309L \ -D_POSIX_SOURCE -D_XOPEN_SOURCE \ -D_BSD_SOURCE -D_SVID_SOURCE \ LinuxAdditionalIncludes LinuxGnuSourceDefines \ LinuxLocaleDefines #else #define LinuxSourceDefines -D_POSIX_SOURCE -D_POSIX_C_SOURCE=2 \ -D_BSD_SOURCE -D_SVID_SOURCE \ LinuxGnuSourceDefines LinuxLocaleDefines This doesn't make sense to me, because I also have libc6: (martin＠lasker) ~cdx/import/xfree86/xc $ make VerifyOS make -f xmakefile VerifyOS make[1]: Entering directory `/project/xemacs/import/xfree86/xc' Building on Linux 2.2.13-23 i686 [ELF] (2.2.13). Linux Distribution: Unknown libc version: 6.1.2 binutils version: 2.9 I could try to fix this without being able to reproduce the problem, but I try to avoid doing this, especially when I don't understand how the XFree86 config magic happens.
