I'm running into a linker issue when moving code that builds on RHEL 6 to Fedora or RHEL 7. Here's a simple reproducer:
Download simple.c from https://github.com/markkilgard/glut/blob/master/progs/examples/simple.c and then run: g++ simple.c -lglut -o simple On RHEL 7, I get this error: ~> g++ simple.c -lglut -o simple /usr/bin/ld: /tmp/ccPIpRiP.o: undefined reference to symbol 'glOrtho' /usr/bin/ld: note: 'glOrtho' is defined in DSO /lib64/libGL.so.1 so try adding it to the linker command line /lib64/libGL.so.1: could not read symbols: Invalid operation collect2: error: ld returned 1 exit status On Fedora 22, I get this error (which is basically the same): ~> g++ simple.c -lglut -o simple /usr/bin/ld: /tmp/ccqKG2Fe.o: undefined reference to symbol 'glVertex2i' /usr/lib64/nvidia/libGL.so.1: error adding symbols: DSO missing from command line collect2: error: ld returned 1 exit status The issue appears to be that the linker would resolve symbols that were in the linked to library on RHEL 6, but aren't doing that in Fedora and RHEL 7. Any ideas on what's going on and how I can fix it without explicitly adding the second level libraries in my build command? Thanks, Dave
