Some more ideas:
- Did you ‘make clean’ before rebulding?
- Did you try with make install to see if there is any difference? Starting root v5.13.01
Or:
- Try to build as originally with CMake, but changing here root/SetUpLinux.cmake at v5-34-00-patches · root-project/root · GitHub Clang with XLClang, as well as in root/SetUpLinux.cmake at v5-34-00-patches · root-project/root · GitHub
