Red Hat Bugzilla – Bug 21143
glibc 2.1.94-3 does not function correctly with libX11.so
Last modified: 2016-11-24 10:17:23 EST
I try to compile povray 3.1g, and it gets to the linking step and reports: /usr/X11R6/lib/libX11.so: undefined reference to `getpwuid_r@GLIBC_2.1.2' /usr/X11R6/lib/libX11.so: undefined reference to `shmctl@GLIBC_2.2' /usr/X11R6/lib/libX11.so: undefined reference to `getpwnam_r@GLIBC_2.1.2' This is on a RedHat Linux 7 system will ALL of the updates listed at redhat's site as of 11/20/2000. This includes the update that make glibc version 2.1.94-3
By any chance, doesn't it use egcs compiler as opposed to gcc? egcs is the compiler for binary compatibility with glibc 2.1 which has glibc 2.1 shared libs in the search path. Either change it to use gcc as compiler, or make sure it includes -L/usr/lib on the gcc command lines (if you want povray compiled by egcs 1.1.2 but against glibc 2.2) or make sure -L/usr/i386-glibc21-linux/lib is present before -L/usr/X11R6/lib if you want egcs 1.1.2 compiled povray against glibc 2.1. This is needed because explicit -L/usr/X11R6/lib causes it to pick libX11 libraries compiled against glibc 2.2, but then compiler's -L/usr/i386-glibc21-linux/lib internal path is used and that takes glibc2.1 in.
It was indeed using egcs. I'll try your suggestions tomorrow when I have time
I followed the suggestion that I put -L/usr/lib in my library path. This fixed the problem. Thanks for the help guys, and sorry for reporting a ghost bug!
