Arch Linux User Repository

The build fails for me in a clean chroot:

Traceback (most recent call last): ... LookupError: setuptools-scm was unable to detect version for /home/xxxx/.cache/paru/clone/python-pyvisa/src/pyvisa-1.15.0.

Make sure you're either building from a fully intact git repository or PyPI tarballs. Most other sources (such as GitHub's tarballs, a git checkout without the .git folder) don't contain the necessary metadata and will not work.

For example, if you're using pip, instead of https://github.com/user/proj/archive/master.zip use git+https://github.com/user/proj.git#egg=proj

Alternatively, set the version with the environment variable SETUPTOOLS_SCM_PRETEND_VERSION_FOR_${NORMALIZED_DIST_NAME} as described in https://setuptools-scm.readthedocs.io/en/latest/config.

ERROR Backend subprocess exited when trying to invoke get_requires_for_build_wheel ==> ERROR: A failure occurred in build(). Aborting... error: failed to build 'python-pyvisa-1.15.0-2': error: packages failed to build: python-pyvisa-1.15.0-2

Grabbing the source tarball from PyPi instead of GitHub solves the problem. Patch below:

@BrainDamage Thank you!

Dropping python-setuptools-scm from the makedeps is not correct. It is still required, and the build will fail in a clean chroot with:

ERROR Missing dependencies:
    setuptools_scm[toml]>=3.4.3

you can double check in the pyproject.toml that it still requires it

@fenugrec Thank you!

Thanks for packaging this. 1.15 was just tagged today; minor changes to build will be required (no more setup.py) and possibly makedeps. possibly something like this (warning, possibly incorrect/incomplete)

Also, please consider adding 'python-linux-gpib' to optdepends (absent from this patch)

Adopted and updated.

Could you bump to latest version?

Hi, could you move python-setuptools-scm from depends to makedepends? Apparently it is used only when building.

I disowned it, have fun :)

I am set up to convert python-pyvisa to a split package that provides both python-pyvisa and python2-pyvisa. To do that, this package would need to be deleted. So if you want to either delete the package or disown it so I can delete it, that would work.
