[Lemon-user] Compiling "lp_demo.cc"

[Kovács Péter]

Dear Andrea,

For using the LP tools of LEMON you also need an LP solver. In your 
current LEMON installation, GLPK is selected as the default solver. To 
compile lp_demo.cc, you should have this library installed on your 
system and you should add the -lglpk directive to gcc:

g++ -o lp_demo lp_demo.cc -lemon -lglpk

Regards,
Peter
