Glpk code does not expect that int's are necessarily 32 bits; in particular, the code must work without changes being compiled for 64-bit int's and pointers. However, I am not sure that gcc provides such option in 64-bit mode. _______________________________________________ Help-glpk mailing list [email protected] http://lists.gnu.org/mailman/listinfo/help-glpk
