Not sure what's happening exactly but the hashbang (interpreter script) in the python script is #!python

The manual says The interpreter must be a valid pathname for an executable file. which this is not.
If I do python flowblade it works, as it bypass the interpreter script.

Looking at code https://github.com/jliljebl/flowblade/blob/master/flowblade-trunk/flowblade#L1 , the original source is correct ; so it got changed somewhere, during the "setup". Did Python 3.12 introduce the issue?

[hfiguiere]

The currently available version has #!/usr/bin/python3 as expected.

Did Python 3.12 introduce the issue?

I think so.

[jliljebl]

I just manually changed #!python to #!/usr/bin/python3 in the test flatpak install I got with:

flatpak install --user https://dl.flathub.org/build-repo/180572/io.github.jliljebl.Flowblade.flatpakref

and now it launches. Now we know what causes not launching issue, but not why we get the change to #!python.

I'm wondering why this is not buildsystem: meson

I'm wondering why this is not buildsystem: meson

I just went out looking for build recipe for numpy build without setup.py, found this and copy pasted.

[jliljebl]

This still does not launch. What do you think, should I try to just add a line to .yaml that overwrites first line of launch script or is there some more 'correct' solution?

[jliljebl]

I found this issue pypa/setuptools#4863 with title build_editable does not emit #!python shebang for scripts #4863

So it is setuptools that is doing this. I will need to look at how fix this as there quite many ways of moving forward from here. I'm closing the PR because pressing Merge pull request would kill all Flowblade Flathub installs everywhere and it is making me nervous. I'll open another one when I have the fix.
