Description Andy 2023-03-18 03:27:56 UTC

When compiling Cmake-3.26.0 with FEATURES=test, two tests fail, the compilertest as well as the dependencygraph test.
Reason as shown in the build log is that the test runs gfortran which does not understand -rtlib=compiler-rt from the LLVM system profile / clang as system compiler.
Dependency graph fails out of the same issue.


Reproducible: Always

Steps to Reproduce:
1. Set profile to LLVM
2. Enable test for cmake
3. Emerge cmake
Actual Results:  
2 out of 608 test fail

Expected Results:  
All tests should pass

Potential solution is enforcing cmake compilation via gcc or switching off tests.
Better would be an enforcing of clearing of the CFLAGS before the tests are run, especially when it comes to gfortran.
