@tauroid Thanks, fixed. I wonder why cling needs the NVPTX target.

CMake Error at tools/cling/CMakeLists.txt:178 (message):
  NVPTX backend is not activated

  Please enable it via -DLLVM_TARGETS_TO_BUILD="host;NVPTX"

changing the relevant line (44) in PKGBUILD yields working install for me

-DLLVM_TARGETS_TO_BUILD="host" \

to

-DLLVM_TARGETS_TO_BUILD="host;NVPTX" \

I ran into a cryptic error message, but found it it was because I didn't have libc++ installed. With that out of the way, it works great!

I have encountered the following error while trying to build the package:

@marmistrz Please, try the new version I've just uploaded.

error: patch failed: tools/Jupyter/kernel/clingkernel.py:67
error: tools/Jupyter/kernel/clingkernel.py: patch does not apply

@pkoretic The error mentioned in the out-of-date message looks like a bug in the tool you are using to install cling.

It seems the jupyter diff no longer applies to the current git version of tools/Jupyter/kernel/clingkernel.py.

@NeoZelux The package is in the base-devel group, and according to the wiki there shouldn't be packages from that group in makedepends.

Hi, I think you should add pkg-config as a build dependency.
