The answer given in this problem was:
check if the wimax code source directory is included in the project, by default this directory is excluded
project->properties->OMNeT++->Makemake
You must include the directories were the Wimax code is or you can include
the whole directory
src/undertest
in my makemake file I have only(check is my project name) check:makemake (deep,recurse) -->(executable) what extra steps should I do in order to include the wimax code source directory in my project?
