I just tried glpk_4_27.dll from your distribution, and am having a
difficulty.
In the following VBA code,
Dim lp As Long
lp = glp_create_prob()
glp_set_prob_name lp, "sample"
The line "lp = glp_create_prob()" works, but the next line
(glp_set_prob_name lp, "sample") gets an error message of "Bad DLL
calling convention". Are these function calls based on the "stdcall"
convention? I can get both lines to work in my version of the DLL when
I explicitly use the __stdcall __export modifiers. But I wanted to test
out your build with Visual Studio as opposed to mine with Turbo C++.

Hello Marc,
couldn't You use the DLL produced by
w32/Build_GLPK_with_VC6_MT_DLL.bat
with Visual C++ 7.0 or 6.0?
(see ftp://glpk.dyndns.org/glpk/glpk_4_27.dll.tar.gz)
Best regards
