[Help-glpk] Linker error while compiling with glpk.h

[Psalm Niranjan]

When I try to compile a C program using glpk functions, I get the the following error at the linker. I've checked the include path and it contains glpk.h and the lib contains libglpk. I'm compiling on a 64-bit machine running ubuntu 11.10
