WARNING: 'flex' is missing on your system.
         You should only need it if you modified a '.l' file.
         You may want to install the Fast Lexical Analyzer package:
         <https://github.com/westes/flex>

So flex needs to be added as a dependency.

@Volker_Weissmann: Should be fixed now, I pointed it to the upstream llvm-13.0 branch. Hopefully someday there's an official release :)

The upstream branch llvm-11.0 works with Arch's current LLVM package. Not sure when that will be released.

@marehr: Thanks for the report, should be fixed!

Currently, the standard compiler is clang-5.x in arch. But, creduce 2.7 is depending on clang-4.x/llvm-4.x. upstream has an open issue to bump it to llvm 5.x https://github.com/csmith-project/creduce/issues/147.

It seems that the recent master branch already fixed this issue and is using llvm 5.x by default. Could you change the source to a snapshot from the github repository?
