@ThePirate42 Can you provide an example of the code where this error occurs?

@QTaKs

After using your PKGBUILD i get the following error:

malloc(): mismatching next->prev_size (unsorted)
Aborted (core dumped)

Made a working PKGBUILD, though at the cost of patching binary files. What I did:

Used a newer version of llvm-project
Added LLVM_ENABLE_BINDINGS=OFF, because ocaml did not let me finish the build.
Added CLING_CXX_PATH="/opt/cling/bin/clang++", because without it there were complaints about not being able to find header files when starting cling: ERROR in cling::CIFactory::createCI(): cannot extract standard library include paths!

Invoking:
  LC_ALL=C ccache -O3 -DNDEBUG -xc++ -E -v /dev/null 2>&1 | sed -n -e ‘/^.include/,${’ -e ‘/^ \/.*++/p’ -e ‘}’ 
Results were: 
With exit code 0

Added binary patching to change all hardcoded paths that contain $srcdir to /opt/cling

But I still haven't managed to fix the errors:

cling JIT session error: Symbols not found: [ __emutls_v._ZSt15__once_callable, __emutls_v._ZSt11__once_call ]
IncrementalExecutor::executeFunction: symbol '__emutls_v._ZSt11__once_call' unresolved while linking [cling interface function]!
IncrementalExecutor::executeFunction: symbol '__emutls_v._ZSt15__once_callable' unresolved while linking [cling interface function]!

Apparently you still can't use std::call_once in cling

Adding 1+1 works perfectly fine for me using the below PKGBUILD. I get though different errors for different code, e.g. when omitting semicolons to have an expression automatically printed. They are related to missing members in the global namespace (so no problem with missing header files).

First of all, sorry for my late response!

@kaelingre: Thank you very much for your effort! I tried your PKGBUILD for v1.2, but I still get a similar error behavior:

ERROR in cling::CIFactory::createCI():
  resource directory /[...]/src/build/lib/clang/18 not found!

@Tyilo and @ThePirate42: I get the same problem. It seems that the resource directory is not correctly set during installation:

resource directory /home/tyilo/.cache/paru/clone/cling/src/build/lib/clang/13.0.0 not found!

The missing files (e.g. stddef.h) are though correctly installed into /opt/cling/lib/clang/13.0.0/include. I haven't quite figured out how to fix it yet.
