homebrew has deprecated qt5

[sunderme]

The consequence is that there is no poppler-qt5 build on homebrew and txs build on OSX fails.
Anybody interested to fix our CD build script to build poppler-qt5 as well ?

texstudio could maintain a homebrew tap itself which provides the required version (and dependences) of poppler. As a test, I've tried extracting [email protected], which uses qt5, to tap muzimuzhi/homebrew-versions and using it in texstudio, see commit muzimuzhi@ffcf49f. Waiting for the CD.

The "Configure" part was just passed, see https://github.com/muzimuzhi/texstudio/runs/2025284634. It is now building. So it seems the extracted [email protected] formula works.

[sunderme]

do you provide a PR (including the formula) ?

[muzimuzhi]

Let me see if the formula could be directly added to texstudio's main repo, instead of importing from a specific homebrew tap repo.

BTW, does the file ./travis-ci/mac/poppler.rb still in use?

[sunderme]

No, it can be replaced

See #1518

[sunderme]

Thanks for looking into it. I have pulled the PR and txs seems to build fine again.

Using brew install poppler as done in PR #1518, is as fragile as before. So when homebrew updates poppler to use qt6, then texstudio's CD will fail just like this time. If homebrew will provide two variants of poppler, that's great. If not, then texstudio will need to either build poppler with qt5 and cmake options -DENABLE_QT5=ON -DENABLE_QT6=OFF, or maintain a modified poppler.rb, and perhaps backups the build results for time saving.

For the second approach, I've tried in muzimuzhi@0c2e47a. Maybe this could be used when "that day" comes.
