Re: [Help-glpk] glpk Limitation? Or what is the problem

Hi!

You are calling C functions from C++. All C code should be embeddes in 
something like:

#ifdef __cplusplus
extern "C" {
#endif

   int C = 30;
   int H = 30;
   int R = 6;

   glp_prob *lp;

   int ia[1 + C*H*R + C*R], ja[1 + C*H*R + C*R];

   double ar[1 + C*H*R + C*R], z;

#ifdef __cplusplus
  }
#endif

   cout<<"Basic matrices of LP problem are defined"<<"\n";

#ifdef __cplusplus
extern "C" {
#endif

   lp = glp_create_prob();

#ifdef __cplusplus
  }
#endif

Alternatively you can define C++ wrapper functions and call them 
directly from C++.
