frescobaldi, frescobaldi-devel: error: Multiple top-level packages discovered in a flat-layout

[ferdy (Giuseppe `ferdy` Miceli)]

ciao,

frescobaldi @3.1.3 and frescobaldi-devel @20201226 fail to build with following error:

error: Multiple top-level packages discovered in a flat-layout: ['i18n', 'linux', 'macosx', 'windows', 'frescobaldi_app'].

To avoid accidental inclusion of unwanted files or directories,
setuptools will not proceed with this build.

If you are trying to create a single distribution with multiple packages
on purpose, you should not rely on automatic discovery.
Instead, consider the following options:

1. set up custom discovery (`find` directive with `include` or `exclude`)
2. use a `src-layout`
3. explicitly set `py_modules` or `packages` with a list of names

To find more information, look for "package discovery" on setuptools docs.

ciao,

for your kind information, I have just upgraded py39-py2app to version 0.28 and just to double-check I gave a try to frescobaldi-devel again which this time build successfully.

cheers -- ferdy
