[Help-glpk] How to compile and link the example "sample.c"

[Zhu Liang]

Hi all

Could you specify how to compile and link sample.c.

When I try "gcc sample.c /usr/local/lib/libglpk.a -o sample.out", there comes a lot of linking errors; see below. I remembered I have successfully compiled and linked it. However, I forgot how I got it..

Thanks.

Liang
