Re: [Help-glpk] RE: sample.c

[Nigel Galloway]

Have you compiled glpk using mingw?

When you do that successfully you will have two files glpk4_44.dll and 
libglpk4_44.a

When you have these copy them both into the same directory as sample.c and use 
-lglpk4_44

When this works move the dll and the archive to a safe_place and try 
-Lsafe_place -lglpk4_44

To actually run sample.exe glpk4_44.dll will need to be somewhere on your 
windows library path. The same direstory as sample.exe is a ok but becomes 
inconvinient after a while. C:\Windows\System is good.
