Linux this is libglpk.so).
An ns-3 example can be found in
https://github.com/nsnam/ns-3.16-git/blob/master/src/click/wscript
Probably you want to create an ns-3 module that encapsulates the GLPK
library first.
Afterwards you can use this module in your projects.

Here is an example:
var x, >= -20, <= 10;
maximize obj: x;
solve;
end;
$ glpsol -m test.mod --wmps test.mps --nopresol
obj = 1.0e+01
$ glpsol test.mps --nopresol
obj = -2.0e+01

This indicates that the GLPK library glpk_4_55.dll is not in the search path for binaries.

Hello Norman,
different Java bindings have been created.
The only one currently maintained is the one available at
http://glpk-java.sourceforge.net
Precompiled Windows binaries are available at
http://winglpk.sourceforge.net
For Debian and Ubuntu a package is available.

Hello Jose,
The errors you report look like you are linking to an old version of GLPK which
does not contain the library function you want to use,
You could check the output of glp_version.
You can influence the library loadpath on OS

Hello Amit,
GLPK is not thread safe. So no two threads should try to call the GLPK
library at the same time.
What you can do is run multiple processes using GLPK at the same time.

Hello Onor,
glp_simplex is the LP solver so you cannot expect integer results.
You have to use glp_intopt to get integer results..
