However, adding -L before /usr/lib/i386-linux-gnu/. I'm compiling with "--enable-32-bit --libdir=/usr/lib/i386-linux-gnu --includedir=/usr/include/i386-linux-gnu" on a 64bit OS and I manually set "export LIBDRM_LIBS=/usr/lib/i386-linux-gnu/".
Comment 1 Alexandre Demers 2012-03-25 22:32:19 UTC 
After testing, I can confirm the problem comes from  "export LIBDRM_LIBS=/usr/lib/i386-linux-gnu/". When it is not set, the build goes all the way to the end.

LIBDRM_LIBS must contain linker flags, not just a path.

It seems to do the trick, thank you.
