How to solve this 'Error Refreshing Makefiles'? - makefile

Question

When I click on Run on my VeinsTutorial (the one that Christoph Sommer made and you might be familiar with it), I get error shown below. Do you have any idea? I really need to get over this error.
Error refreshing Makefiles
Reason:
you have both .cc and .cpp files -- specify -e cc or -e cpp option to select which set of files to use
make MODE=release all
make: *** No rule to make target 'all'. Stop.
"make MODE=release all" terminated with exit code 2. Build might be incomplete.
'
'Simulation terminated with exit code: 1
<!> Error: NED type 'veinstutorial.src.TutorialAppl' could not be fully resolved due to a missing base type or interface, at C:\Users\konra\git\repository\carlogicapi-master\carlogicapi-master\tutorials\VeinsTutorial\src\TutorialAppl.ned:19
End.
This is the MAKEFILES FILE where I should change something, but I cannot see where it should be changed.

Answer 1

I just had to change the extension of the TutorialAppl.cpp to CC.
I guess sometimes we look for the difficult way to solve problems and it is actually the easy way you have to take :)
Thanks for your attention.
