Describe the bug
Just posting this for help for potential users encountering this issue in the future.
At some point, we were unable to run a script with the “+” compilation, ie root -l test.cpp
worked, but root -l test.cpp+
failed with the following cryptic error message:
root -l test.cpp+(\"e\")
root [0]
Processing test.cpp+("e")...
Info in <TUnixSystem::ACLiC>: creating shared library /tmp/ /tmp//tmp/./test_cpp.so

/tmp/ /tmp//tmp/test_cpp_ACLiC_dict.cxx:3:32: error: extended character is not valid in an identifier
Finally, we figured out that there was some kind of non-standard tab or space symbol within .rootrc’s ACLiC.BuildDir, after copying from an html file to “nano” or something like that. Removing all characters before the path and putting a new space solved the issue.
To Reproduce
Add a character such as “
to ~/.rootrc
after ACLiC.BuildDir:
