Hello Jifi, all Those conditional macros should not be required.
Is your GLPK code is a 'main' function? Maybe the global declarations work until the GLPK function call that chokes? See here for a simple example: http://en.wikibooks.org/wiki/GLPK/Using_the_GLPK_callable_library#Short_example In addition, this is not good style: using namespace std; See: http://stackoverflow.com/questions/1452721/why-is-using-namespace-std-considered-bad-practice Instead use: std::cout << "Message" << std::endl; Finally constants can help avoid bugs: const int C = 6; HTH, Robbie ------------------------------------------------------------ To: Help Glpk <help-glpk@gnu.org> Subject: Re: [Help-glpk] glpk Limitation?
