build.py causes FTBFS from alternative build tool #640
Description
Hey, package maintainer from Arch Linux here. 👋
Just picking up our conversation from #600.
I can't seem to get reuse to build from source when using the build module to generate Python wheels.
Why do we use build? Well ...
Because there are ~5 (at last count) different ways to build a Python project that is PEP-517 compatible, hence us trying to only use the `build` module to build wheels rather than remembering the various CLI invocations for each individual tool. `build` is smart enough to hook into these other PEP-517 compatible builders and use their own build systems to generate a wheel/sdist archive.The only hint I have of something breaking is running the following:
[root@chroot reuse]# python -m build --help
po/gl.po: warning: Charset "CHARSET" is not a portable encoding name.
Message conversion to user's charset might not work.
The command fails successfully, resulting in no wheel archive in dist/.
Any subsequent invocations of python -m build --help result in no output and no wheel archive in dist/:
[root@chroot reuse]# python -m build --help
[root@chroot reuse]#
For reference, this is the normal output:
$ python -m build --help
usage: python -m build [-h] [--version] [--sdist] [--wheel] [--outdir OUTDIR] [--skip-dependency-check] [--no-isolation] [--config-setting CONFIG_SETTING] [srcdir]
A simple, correct PEP 517 build frontend.
By default, a source distribution (sdist) is built from {srcdir}
and a binary distribution (wheel) is built from the sdist.
This is recommended as it will ensure the sdist can be used
to build wheels.
Pass -s/--sdist and/or -w/--wheel to build a specific distribution.
If you do this, the default behavior will be disabled, and all
artifacts will be built from {srcdir} (even if you combine
-w/--wheel with -s/--sdist, the wheel will be built from {srcdir}).
positional arguments:
srcdir source directory (defaults to current directory)
options:
-h, --help show this help message and exit
--version, -V show program's version number and exit
--sdist, -s build a source distribution (disables the default behavior)
--wheel, -w build a wheel (disables the default behavior)
--outdir OUTDIR, -o OUTDIR
output directory (defaults to {srcdir}/dist)
--skip-dependency-check, -x
do not check that build dependencies are installed
--no-isolation, -n do not isolate the build in a virtual environment
--config-setting CONFIG_SETTING, -C CONFIG_SETTING
pass options to the backend. options which begin with a hyphen must be in the form of "--config-setting=--opt(=value)" or "-C--opt(=value)"
After flailing around, I've managed to find a horrible horrible hacky workaround that I most definitely am not proud of. Here be dragons.
