Dear Developers,


First, let me thank you for your effort in putting together this tool,
for free.


I would like to request, if that is at all possible, to include with the
GLPK distributions somewhat detailed instructions about building GLPK
from source using MinGW and/or MinGW64 under Windows 7/8.


I am not a computer expert, but can find my way around the computer, so
I guess I could be an "average user" case. I used MinGW to compile GLPK
from source, and the resulting executable GLPSOL works perfectly.
However, when I tried to use GLPK as a library, even though the
compilation goes through, the resulting executable crashes every time I
call it, and I haven't been able to find what the problem is.


I am wondering if this is an issue with a 32 executable being used in a
64 architecture, maybe I am not aware of some 32bit library that I am
calling inadvertently, or maybe it is a 64 library that I am using from
my 32bit application.


I have both MinGW and MinGW64 (the TDM package) in my computer, but only
MinGW is in the path.


To get around this issue, I just created a virtual machine (VirtualBox)
with Linux Mint in it, and I am running GLPK from there. Of course, in
linux, it compiles ans installs without a hitch. Thanks for that!


Thanks in advance for any help you can provide. If not able to help me
in my current situation, at least please consider the building scripts
for MinGW users in Windows.


Thanks!
