RE: [Help-glpk] Problems in using GLPK on MATLAB

[#LI WEN#]

Hi, Robbie,

Thanks for your advice. I just solved my problems.

1. compile glpkmex v2.8. 
  My problem is when I run the makeglpkmex.m, I cannot find the required 
'libglpk.a'. I think it should be the library file. So I replaced with glpk.lib 
which is under the GLPK directory (I installed GLPK v4.34 on my PC, which is 
downloaded from http://gnuwin32.sourceforge.net/packages/glpk.htm). However, it 
doesn't work.
  So I downloaded the latest source code, and compile it to get a glpk.lib. 
With this glpk.lib, I successfully compiled glpkmex v2.8.

  Despite the version problem, I found that the glpk.lib file under the GLPK 
installation directory is quite small (55KB), compared with the glpk.lib 
compiled by myself(>2MB). Actually, I compiled the source code of GLPK v4.34, 
which is the same version with the one I installed. The glpk.lib file is above 
1MB. But glpkmex v2.8 only works on glpk whose version is higher than 4.36.

2. compile my glpkmex file.
  I have a different interface file, which comes from another program I 
downloaded. When I tried to compile it, I got some errors as follows:

> ------------------------------
  I searched on Google, and found it might due to the version problem. Some 
functions such as lib_env_ptr and insist are not supported anymore in new 
versions. They are supported in versions ealier than 4.14 (which is quite old).
  Now I think I should modify the program to use glpkmex v2.8 or compile the 
older version glpk. I prefer the former one, as it is said there're some memory 
bugs in older version.

Thank all of you for your helps.

Best regards,
LI Wen

Hi Li  (off-line)

If you solve your problem, can you post back to the
[Help-glpk] list.  Or if you find out anything useful.
I will then update the GLPK wikibook page:

  http://en.wikibooks.org/wiki/GLPK/Matlab#GLPKMEX

I don't use MATLAB these days.  But I guess you
may need to work on the GLPKMEX code to bring
it up to date?

best wishes
Robbie
