Wrong Python default path in QGIS server on macOS

Original Redmine Issue: 22029
Affected QGIS version: 3.6.2
Redmine category:qgis_server

---

It appears that QGis server layout is broken when compiled on MacOS. Frameworks are expected in @loader_path/../../Frameworks/ whereas the right access path is @loader_path/../../../../Frameworks and for libraries instead of @loader_path/../lib this is @loader_path/../../lib. This is inconvenient, though fixable using install_name_tool.

However, when QGIS server starts, the path given to the Python interpreter is wrong, and that causes the server to fail

This path: '/Applications/MacPorts/Qgis3.app/Contents/MacOS/fcgi-bin/../Resources/python' is wrong. It should be '/Applications/MacPorts/Qgis3.app/Contents/MacOS/fcgi-bin/../../Resources/python'. So far I have failed to find out where this path was set (in order to correct it). Can anyone help?

Can you please test with https://qgis.org/downloads/macos/nightly2/qgis_nightly2_master_20200923_062253.dmg
You can run /Applications/QGIS.app/Contents/MacOS/bin/qgis_mapserver with QGIS_SERVER_LANDING_PAGE_PROJECTS_DIRECTORIES environment variable to your project folder

@PeterPetrik I never tested QGIS Server on macOS, I guess I can try.

[PeterPetrik]

I believe this was fixed in QGIS 3.16, cannot we close the issue? @gioman why the Feedback was removed, is there any issue with the implementation ATM?
