/usr/bin/ld: cannot find -lGL
Well that is odd. It means that the linker cannot find libGL even though it is installed on the system. Try? /sbin/ldconfig -p | grep libGL.so You should see something like this. [martyn at braque-iarc-lan minutes]$ /sbin/ldconfig -p | grep libGL.so libGL.so.1 (libc6,x86-64) => /lib64/libGL.so.1 libGL.so.1 (libc6) => /lib/libGL.so.1 libGL.so (libc6,x86-64) => /lib64/libGL.so
Odd: [root at lri-105689 rgl]# /sbin/ldconfig -p | grep libGL.so ????????libGL.so.1 (libc6,x86-64) => /lib64/libGL.so.1 ????????libGL.so.1 (libc6) => /lib/libGL.so.1 ????????libGL.so (libc6) => /lib/libGL.so
Yours is not quite the same. I have a link to the 64-bit version of libGL.so, but you don't. Your link is to the 32-bit version (i.e. without the qualifier x86-64 in brackets) which you have removed. This means your linker cache is out of date. Try /sbin/ldconfig as root (or with sudo) and it should resolve. Martyn
