When I try to compile a C program using glpk functions, I get the the

contains glpk.h and the lib contains libglpk. I'm compiling on a 64-bit
machine running ubuntu 11.10

/tmp/ccPR8ZKY.o: In function `main':
scheduler_main.c:(.text+0x10): undefined reference to `glp_create_prob'
scheduler_main.c:(.text+0x2b): undefined reference to `glp_set_prob_name'

IIRC most of the GLPK function names are #defined to something else.
I suspect that you did not #include glpk.h
and thus did not get the right names.
Did you get any warnings about undeclared functions?
