Verification

• [X] I ran brew update and am still able to reproduce my issue.
• [X] I have resolved all warnings from brew doctor and that did not fix my problem.

What were you trying to do (and why)?

To install formula qt when upgrading all Homebrew.

What happened (include all command output)?

It was not possible to install qt from the bottle as the bottle for linux/5.15.0-1016-gcp/amd64 is not available, see here.

I tried to build qt from source which failed. It is likely that qt also failed to build in the CI.

What did you expect to happen?

That qt installed from the bottle. qt takes a long time to build, so it's impractical to build it in the local machine.

Step-by-step reproduction instructions (by running brew commands)

brew install qt

I'm not sure what actionable issue there is here. Yes QT builds are slow, no it does not have a bottle.

[carlocab]

It does build, but the resulting build appears to be very broken and fails brew test qt.

We could use some help diagnosing and fixing the failure. See https://github.com/Homebrew/homebrew-core/pull/111031.

[gzagatti]

brew will throw an error if no bottle is available and on top of that it prints a message discouraging the user from installing from source as this modality "is unsupported". As such, I assumed that it was a bug and opened this pull request.

Error: qt: no bottle available!
You can try to install from source with:
  brew install --build-from-source qt
Please note building from source is unsupported. You will encounter build
failures with some formulae. If you experience any issues please create pull
requests instead of asking for help on Homebrew's GitHub, Twitter or any other
official channels.

I have also noticed that qt version 6.3.1_3 has a bottle for linux/5.15.0-1016-gcp/amd64 which you can see here which suggests that the lack of a bottle for version 6.3.1_4 is a bug of the build process.

Perhaps, I would suggest that when upgrading brew it should refrain from upgrading un-bottled Formulas to avoid disruption and then warn the user about that. This is not the first time that I have faced this type of issue. It can be quite disruptive when updating brew on your daily routine and especially for Formulas that need a lot of compilation and which are low-level dependencies for other Formulas.

In the particular case of this issue we need to solve #11031. I am afraid I don't know anything about qt to be of much help.

[carlocab]

This seems to be a brew bug. See Homebrew/brew#13922.

[iMichka]

We have built a bottle now. Is this working for you now?

[gzagatti]

I can confirm that qt version 6.4.0 now installs from bottle in my machine (Ubuntu 22.04) without any issues.
