Re: [Help-glpk] compilation problem in ns3

[Heinrich Schuchardt]

Hello Ali,

waf is a build system. The project is hosted at http://wav.io

Please, read the documentation of waf at https://waf.io/book/

You will find that the file controlling building is called wscript. In
this file you have to provide the dynamic link libraries you want to use
(for GLPK on 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.

Best regards

Heinrich Schuchardt
