OMNET++ integration with CPR API REST

[JuanC]

Dear all,

I have a simulation in OMNET++ that needs to make a request from an external API server running. I have used a C++ library called CPR that I have tested in Eclipse directly and works fine (After linking the proper directories and executables through Project properties->C/C++ build->Settings->GCC C++ Linker->Libraries->[-l section] and then add the CPR library). However, I don't know how to do the same linking process of the library while using OMNET++ (It should be possible as OMNET is based on the Eclipse IDE). I am running OMNET++ 6.0pre11 in Ubuntu 20.04 LTS. 

Could someone explain me how to link the libraries properly please? 

Thanks in advance

If you are using inet, the easier is to modify the makefrag file.

INCLUDE_PATH += -ImyPath

LIBS += -lmyLib

Got it, but should I modify the makefrag from the Simu5G, from INET or from the CPR library? 

Additionally, the letter is an L or an I ??. I'm asking because usually the -I in Include Path is a capital I as in INDIANA and the -l in LIBS is a lowercase l as in lower case lima. 

PD. I modified the makefrag from the SIMU5G and now it cannot find the SIMU5G library.

If you are using the library in simu5G, you need to include the library in the Simu5G project. You can include additional libraries in the Project properties->OMNeT++->Makemake-> “Makemake options” -> Link

Ahh, ok got it. I tested it and eventually it worked. But first I had to copy the library files (.so) to my root file (usr/lib) because they were in (usr/local/lib). But in any case, it is safe and sound now, thanks a lot.
