Description Lennart Brinkmann 2020-09-22 13:47:13 UTC

Description of problem:

After updating clang-libs to 10.0.1-2.fc32.x86_64 the ClangCodeModel plugin in Qt Creator fails to find the clang header files, displaying warning messages. 

Version-Release number of selected component (if applicable):
qt-creator-4.12.4-1.fc32.x86_64

How reproducible:
always

Steps to Reproduce:
1. Open Qt Creator
2. Create a new Qt Widgets Application

Actual results:
Qt Creator displays a warning message
Warning: The code model could not parse an included file, which might lead to incorrect code completion and highlighting, for example.
cstddef:50:10: error: 'stddef.h' file not found
...

Expected results:
No warning

Additional info:
The ClangCodeModel plugin seems to hardcode the path to the clang headers.
strings /usr/lib64/qtcreator/plugins/libClangCodeModel.so | grep /usr/lib64/clang/
/usr/lib64/clang/10.0.0/include

Rebuilding the qt-creator package would probably fix the issue for now.

The FEDORA-2020-04275c89c0 update fixes the issue for me.

Is there a way to prevent this issue from reappearing on the next clang update?
