I am trying to set up the easylogging++ in a project, and I run into the following issue:
Macro INITIALIZE_EASYLOGGINGPP should be called only once in the project. Now, if I call this macro from my main.cpp and only include easylogging++.h in main.cpp - everything works fine. However, when I try to include easylogging++.h in more .cpp files, I get linker issues with undefined references (as if the macro hasn't been called).
If I place the call to this macro in a file that is alphabetically before the main.cpp, linker resolves everything normally. In the linking phase objects are sorted alphabetically.
Is there a nice way to solve this issue? Or will I have to try to force a different order of files at linking time?
I am not that much experienced with this sort of issues, tried googling it, couldn't find the solution. If there is already a similar question, sorry, couldn't find it.
Thanks for the help!
Some programmer dude was right, there isn't a problem with linking+macroes.
After trying to recreate the minimal example to post it here, I realized there was a bug in the CMakeLists.txt which caused the main.cpp (in which I expanded the easylogging++ macro) to be excluded from the build under some circumstances.
Thank you all for your time and sorry for the stupid question.
