The below bug seems fixed in version 1.1 (with LLVM16 this time...). Please use this PKGBUILD:

@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.

The built cling binary doesn't seem to work for me:

Nice, thanks for the trick.

@carlosal1015: Sorry for the late reply! I prefer to leave the default configuration as it is. If you want to allow redefinition of variables, functions etc., you can enter the following statement in the interactive shell: cling::runtime::gClingOpts->AllowRedefinition = 1;

@kaelingre: Many thanks for your helpful preparatory work! I updated the PKGBUILD for v1.0. In the course of this, I also added !debug to the options.

kaelingre commented on 2024-05-06 10:25 (UTC)

It would be useful to disable the debug option by default (i.e. add !debug to the options). The debug package that is produced is huge, 6.4GiB+.

kaelingre commented on 2024-03-24 10:09 (UTC)

I created a PKGBUILD for v1.0. Note that I hard-coded a specific llvm version (cling-llvm13-20240318-01) to build against:

There are no tags v1.0 for llvm and clang. Compilation will give errors if bump version to 1.0.
