External names are mangled. Probably your program is in C++, not in C.

If your program is in C, you should change settings in ide to tell the
compiler about that, or use the extension '.c' rather than '.cpp'.

If your program is in C++, you should use the following construction:

extern "C" {
#include "glpk.h"
}

because all glpk headers are written in C, not in C++.
