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 On Sat, Nov 21, 2015 at 6:54 PM, Heinrich Schuchardt <[email protected]> wrote: > Hello Ali, > > waf is a build system.
