p3-ex4 does not compile on llvm/clang 16.05

[Kevin-Delnoije]

I am using the apt installed llvm 16 version on ubuntu 22.04

-- Found supported version: LLVM 16.0.5
-- Using LLVMConfig.cmake in: /usr/lib/llvm-16/cmake
-- Found supported version: Clang 16.0.5
-- Using ClangConfig.cmake in: /usr/lib/cmake/clang-16

the following functions are not found.

these seem to have been added 2 weeks ago in clang/Interpreter/Interpreter.h

Yes, unfortunately most examples we don’t support llvm 16 or any llvm older than two weeks :(

PS: I need to adjust the supported llvm version in cmake.

[Kevin-Delnoije]

no problem, will try out the apt development branch of llvm17 later today.
