Also, I have made some corrections to properly handle dictionary generation in which the header files are not in the same directory as the source files. I’ve attached my most recent version for those who are interested in this. Be sure to change the filename to FindROOT.cmake (The forum would not let me upload the file with this extension.) FindROOT_cmake.C (5.94 KB)
After some further study of cmake I have again improved the FindROOT.cmake file. This is a reduction of the previous file which was performing unnecessary steps. I’ve also added the variable ROOT_GUI_LIBRARIES for those who are compiling ROOT gui with the standard root-config --glibs. I also removed extraneous commented lines.
I am not making use of the REFLEX_GENERATE_LIBRARY command so it has not been tested, but I did not alter it significantly enough to change its functionality.
The attached file should be renamed to FindROOT.cmake FindROOT_cmake.C (5.49 KB)
I found an issue with ROOT_GENERATE_DICTIONARY for ROOT 5 with GCC > 4.9 on Arch Linux
rootcint would crash when given every directory from INCLUDE_DIRECTORIES
the culprit turned out to be "-I/usr/include"
The “continue()” command was added to CMake in December so I’ve added that here: github.com/dougphy/frate/commit … be6a38d4b4
To skip adding -I/usr/include to the custom command
Just curious, do you include /usr/include on purpose or is it in INCLUDE_DIRECTORIES by default? If by default, why does it cause an issue with your distribution and not previously? These raises the more general question of why does Cint crash when this directory is passed to it?
/usr/include is part of INCLUDE_DIRECTORIES by default – I also find the crash a bit weird. It only occurs on Arch with ROOT5 and not ROOT6. Like I said – I think it might be a GCC issue, definitely not sure though. I’m making this assumption based on the following error:
