Using debian-compat (=12) fails

[ikus060]

I'm trying to upgrade my package to use compat 12. It's failing with this error Please use the third-party "pybuild" build system instead of python-distutils

Is compat 12 event support ? The documentation still make reference to compat 9

I think there is a change with compatibility level 12, which needs a change with dh-virtualenv. For immediate fix you could try building with compat 11?

Seams to be working with compat=11.

Leaving this bug open as it still relevant. compat=12 is not working

I believe this could be fixed if you use --buildsystem=dh_virtualenv. However, note that you will need to add

export DH_VIRTUALENV_ARGUMENTS

to avoid the error

virtualenv: error: unrecognized arguments: --no-site-packages

as this flag has been removed in recent virtualenv versions (see this stackoverflow answer for details) (this should be resolved by #334).

You will also need to add a dependency on python(3)-pip, as the buildsystem uses the host pip... (this should be resolved by #333).

In addition, you must provide a requirements.txt, because it is unconditionally used, even if it does not otherwise exist.

Seams to be working with compat=11.

Note that according to the man page,

The compat 11 is discouraged for new packages as it suffers from feature interaction between dh_installinit and dh_installsystemd causing services to not run correctly in some cases. Please consider using compatibility mode 10 or 12 instead. More details about the issue are available in Debian#887904 and https://lists.debian.org/debian-release/2019/04/msg01442.html.

Hi,

The issue is caused by dh detecting the presence of a setup.py file and thus selecting distutils as build system. The Debian project does not ever change the selection order to ensure deterministic builds. The correct fix would be to pass --buildsystem=none to dh, but that also throws an error currently - but I fixed this in #347 .

Another clean way to solve this issue until the next release is to create an empty Makefile in your repo. dh will detect this before distutils and thus select it. Then your Makefile is called by dh but does nothing (just make sure you don't have a build/install target!).

@nailor I guess a dh_virtualenv release would be kind of nice by now :-)

kr, Mat

I was able to get compat 12 working ok with debian bookworm: https://github.com/flaccid/deb-virtualenv-example
