Hi @JKSH, thanks for your reply!
I believe the GLIBC macros are from
/usr/include/features.h. Is there a way to have QT Creator index that file without explicitly including it in the project? The project itself builds fine, so I'd rather not clutter up our cmake files with unnecessary directives. (The same reasoning applies to creating a
clang_hacks.h that defines the GCC macros and symbols to keep clang happy).
