While attempting to compile Xerces 2.7 on MacOS, I discovered what I think
is a bug in gcc, which I'm using for all phases of build. The c++ preprocessor
is emitting line number statements which have an inconsistent number of
arguments after the file name, e.g.:
# 1 "/usr/include/xercesc/util/XMLEnumerator.hpp" 1 3 4
vs.
# 25 "/usr/include/xercesc/util/XMLEnumerator.hpp" 3 4
and, in the former case (with the extra number), it seems to introduce some
compiler behavior where a subsequent template class definition will be
rejected with the misguiding error message "template with C linkage".
I have whittled the problem down to a single preprocessed source file that
exhibits this
problem - will try to attach it once I can figure out Bugzilla's UI.
Thanks for your help and advice!
