[Lemon-user] Problem with GLPK

[Kaveh Azizian (Dr)]

none of them works!! Problem still insists. I think the problem is linking between GLPK and Lemon. Any idea?

Oh, sorry, I missed that you should also link to LEMON itself:

g++ -lglpk -lemon lp_demo.cc

(Or
g++ -lemon -lglpk lp_demo.cc
if the command above does not work. GCC is sensitive to the order of
the linked libraries, and I'm always confused about the right order.)

Regads,
Alpár
