I compiled Rolisteam on Debian few weeks ago.
1/ RCSE means Rolisteam Character Sheet Editor. You may want to compile it as well if you plan to use Rolisteam managed Character sheets.
2/ This is the list of package, I have installed on my debian VM:
For RCSE, please install poppler-qt5-dev as well.
-Add "return true" at line 176 of mapframe.cpp file. (just between file.close() and the }.
-If your compiler has difficulties to find fabs function.
just include cmath at the top of the file
I may give you updated source code. If you have any problem.
4/ Do not hesitate to ask me any questions.
I know that the English of the documentation is bad and the documentation is old.
I'm currently working on a new version of the documentation.
