Re: [Help-glpk] spx_simplex: problem has no rows/columns

[Sana Jawad]

Hey,

I suspect that the problem is related to copying the right files in the right folder. I have tried copying all the dlls in the C:\Windows\System32 folder; but nothing seems to make a difference. 

The java library path is as follows:

System.out.println("java.library.path="+System.getProperty("java.library.path"));

java.library.path=C:\Program Files\Java\jre6\bin;.;C:\Windows\Sun\Java\bin;C:\Windows\system32;C:\Windows;C:/Program Files/Java/jre6/bin/client;C:/Program Files/Java/jre6/bin;C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem;C:\Windows\System32\WindowsPowerShell\v1.0\;C:\Program Files\System Center Operations Manager 2007\;C:\Program Files\TortoiseSVN\bin;c:\Program Files\Microsoft SQL Server\100\Tools\Binn\;c:\Program Files\Microsoft SQL Server\100\DTS\Binn\

Any help is highly appreciated.

Thanx,
Sana

Hello Sana,

please, unzip the file downloaded from
http://sourceforge.net/projects/winglpk/files/winglpk/GLPK-4.42/winglpk-4.42.zip/download
to a new directory.

Change to the w32 directory, if you use a 32bit windows (or to w64 when
using 64bit Windows.

Execute the installation check

Are the two examples executed correctly?

Best regards
