Re: [Help-glpk] compilation problem in ns3

[Ali Marandi]

Hello Heinrich,

Thank you very much, for your comprehensive response.

I went through the manual of ns-3 so as to create a new module. Typically, when we need to create a module, it is required to have two files, i.e. one header file (extension .h) and another file which defines the methods declared in the header file (extension .cc). 

Based on the above argument, when I need to create the module "Glpk", I do have the first file (glpk.h). However, I cannot find some file (e.g. glpk.cc) which implements the methods declared in the glpk.h (e.g. glp_create_prob). Could you please give me some valuable guidance on how to deal with this ?

Thanks a lot in advance, for your guidance.

Best regards,

A

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
