Might be because you have already been using LLVM-11.1. It works fine here with 11.0.1, but atm my system does not want to update to 11.1 because of some dependency problem. I will try to solve this and see if I can then reproduce the issue and whether there are any fixes for this upstream.

[Comment 10 Harald Judt 2021-02-22 13:37:44 UTC]

After updating to llvm-11.1, I can now reproduce this issue. I don't know yet how to best solve it, but simply changing the requirement of "LLVM 11.0" to "LLVM 11.1" in CMakeLists.txt fixes it. Simply using "LLVM 11" there doesn't work, and I wonder about the update process for the user who compiles with LLVM 11.0, but then updates to LLVM 11.1.

Any recommendations how to properly treat this in the ebuild?

[Comment 11 Harald Judt 2022-07-18 14:11:03 UTC]

Closing resolved, as there are newer versions available and the old one has been removed.
