Re: [Help-glpk] [Fwd: Makefile for MinGW on Windows 7/8 for 32bit/64bit architectures]

Happy new year Y'all

 

Sorry for the delay, I was away for 6 weeks before xmas. Yes this is good for linking to create static glpk applications. If you want the lib and dll files you must do the following:

 

Unpack glpk_4_55 distribution and open an msys terminal in the top directory.

 

# Create suitable Makefiles

./configure

 

# Build glpk using these Makefiles

make

 

# Construct a dll

dllwrap --dllname glpk.dll --def w32/glpk_4_55.def src/*.o

 

# Generate the .lib file

dlltool --def w32/glpk_4_55.def --dllname glpk.dll --output-lib glpk.lib

 

# Install

copy src/glpk.h, glpk.dll, glpk.lib wherever you want them

 

# Test

Change directory to wherever you installed glpk.h, glpk.dll, glpk.lib. Copy glpsol.c and say yacfs.mod from glpk examples.

 

# Compile glpsol

gcc -I . glpsol.c -o glpsol.exe glpk.lib

 

# Run glpsol

glpsol --math yacfs.mod

Thanks Nigel. I just did that and it compiled ok. Sorry for asking this, it seems that the solution was obvious...I got the glpsol.exe and the libglpk.a files. I tested the glpsol.exe and it is fine. Now, I wonder, would this .a file be good to link with a gcc-compiled application that would run on Windows (inside msys), or do I need to somehow create .lib/.dll files?

 

Regards,

David

The easiest way to compile GLPK using MinGW is to also install MSYS.
MSYS provides the gnu make toolchain so you may then compile GLPK as you
do on Linux using the supplied Makefile as is.
