Porting to Win32 - MinGW32

[GoogleCodeExporter]

Hi all,

I would like to port cspsol to windows operating system. I have compiled and 
generated GLPK yesterday with MinGW32 as described in their instructions. Is 
there a possibilty to define a proceure for compiling the package with gcc on 
windows (MinGW)?
Thank you,

Marko Bursic

I have compiled and made cspsol.exe using MS Visual Studio 10.0. The version 
1.02 didn+t worked for me: the compiler reported an error in bb_node.cpp in 
line 58 {ctor}. But I more liked the philosophy of cspol-minicut, so I tried to 
build up, et voila - it built without problems.
I have added w32 folder in directory of cspsol dir, the version of GLPK is 
4.44, also built with MS VS 10.0 .

Hi, It's me again,

Actualy I made a mistake, I have built succesifuly the version 0.7 and neither 
1.02 or cspsol-minicut, the MS compiler reports a syntax error in line 58 of 
bb_node.cpp:
error C2061: syntax error identifier '{ctor}'
ctor stands for CONSTRUCTOR as I've seen on net. Does anybody have a solution 
to set the MS compiler corretly?

Hi, again.
I can build versions up to 0.9, after that bb_node.cpp changed,  there is also 
used a function lround(), which is not compatible with windows. I had defined 
it as:
#define lround(num) ( (long)(num > 0 ? num + 0.5 : ceil(num - 0.5)) )
I don't understand what the MS compiler doesnt like. If anybody has an idea to 
overcome this problem or any other idea how to compile for win, please help.

Dear  Vijay,

I think I have found the solution of problem, but please make a check since I 
am an absolute beginer in programming. The line 58 in BBNode.cpp is:

BBNode * temp_node = new BBNode::BBNode(0, this);

I have patched it:

BBNode * temp_node = new BBNode(0, this);

cspsol.exe was created and works good, I will make tests and upload batch files 
for compiling and linking and output tests as well.

Thank you. Your patch will be committed and will be available in next release. 

I assume you are using MS Windows, if you are not already using it, you can try 
using SVN client for MS Windows (http://tortoisesvn.tigris.org/). This will 
allow you to directly commit the patch (if correct).
