`pip install clang` is obsolete

[sztomi]

The PyPI package is one minor version behind the latest stable (3.9) and states in its description:

OBSOLETE. LLVM-CLANG NOW PUBLISHES PYTHON PACKAGE. JUST ADD THE OFFICIAL llvm-3.7 repo in your apt.

This makes it quite hard to compile on a system which has 3.9. I don't exactly know how to solve this apart from compiling an installing 3.8 on my system from source (which I'd prefer to avoid). Any suggestions?

At least on linux you can set the SIPLASPLAS_DOWNLOAD_LIBCLANG cmake option to ON and let siplasplas download the clang release for you. This is the easiest way to ensure you're working with the right python bindings:

set(SIPLASPLAS_LIBCLANG_VERSION 3.8.0)
set(SIPLASPLAS_DOWNLOAD_LIBCLANG ON)
include(siplasplas-bootstrap.cmake)

That trick does not fix your issue, but at least gives your a chance to play with siplasplas while I update the install process :)

Thanks a lot for the info, I wasn't aware the python bindings were being included in the release.

Thanks, that seems to have helped a bit, but now I'm getting a different kind of error:

This is on Arch.

That error is related to libcurses dependencies on Arch (I must open a FAQ page with this kind of stuff...). The issue is badly documented here.

Hope it helps.
