qt@4 bottle broken since openssl 1.0 was removed from homebrew-core about homebrew-qt4

[qq42]

brew uninstall --force [email protected] ran but did not display any output, but then brew upgrade still says:

==> Upgrading 1 outdated package:

Thank you for the pointer! It gave me a few more ideas to try. I ran brew info [email protected] which led to running brew install [email protected] which then allowed brew upgrade to successfully run!

If you need to have [email protected] first in your PATH run:
  echo 'set -g fish_user_paths "/usr/local/opt/[email protected]/bin" $fish_user_paths' >> ~/.config/fish/config.fish

For compilers to find [email protected] you may need to set:
  set -gx LDFLAGS "-L/usr/local/opt/[email protected]/lib"
  set -gx CPPFLAGS "-I/usr/local/opt/[email protected]/include"

At the time of writing the above steps by @qq42 are still necessary on my macOS 10.13.6 to install qt4. In short:

brew tap cartr/qt4
brew uninstall --force [email protected]
brew install [email protected]
brew install qt@4

[cartr]

Thanks for reporting this! I'll look into re-adding openssl 1.0 to this tap.

[cartr]

@sandvige Thanks for your help! I've gone ahead and merged the OpenSSL branch into master and built some new bottles.

[devernay]

Thanks for looking into that!
The removal PR is here: Homebrew/homebrew-core#46876
But I would actually recommend compiling against openssl 1.1, using this patch (originated from debian, then MacPorts, and finally modified by me):
https://github.com/NatronGitHub/Natron/blob/RB-2.3/tools/MacPorts/aqua/qt4-mac/files/patch-qt4-openssl111.diff

Thanks a lot for keeping this tap alive, which allows building qt4 apps on Travis CI (among other things)

[sandvige]

Anything new? How can we help?

[cartr]

@sandvige I've created a branch (https://github.com/cartr/homebrew-qt4/tree/readd-openssl-1.0) that adds OpenSSL 1.0 to the tap. I'd appreciate it if you could test that branch out and tell me if it works on your system. (I wasn't able to get @devernay's patches to build in the version of Qt used in this formula.)

The main blocker right now is getting bottles built -- I haven't had a lot of time to work on that lately, but I'll take another swing at it.

[cartr]

And more generally, I don't use a Mac as my primary computer anymore (because I got tired of software updates breaking stuff all the time), so it's kind of a hassle for me to create and test updates to this tap. I'd really appreciate it if people filed pull requests to fix issues they found.

[sandvige]

@cartr, thanks for your answer!

I will try my best to help you. So far, I'm not an Homebrew expert, and I tried something that might be "dumb" to test (because I don't have a mac neither). We're using your tap with a Travis job, here is the previous code I was using to pour your tap:

brew tap cartr/qt4
brew tap-pin cartr/qt4
brew update
brew install qt@4

I forked your repository, and since it looks like it's not supported to pour bottles from github through branches, I merged your branch into my fork's master: sandvige#1

Then, I patched my job with this:

brew tap sandvige/qt4
brew tap-pin sandvige/qt4
brew update
brew install qt@4

Here are the logs:

brew tap sandvige/qt4

So I tried to uninstall the [email protected], as mentioned, before running brew install qt@4:

+brew uninstall [email protected]
Error: No such keg: /usr/local/Cellar/[email protected]

I'm almost sure I'm missing an important part of the process, could you point out a documentation that shows and explains how to start building and publishing taps?

[sandvige]

@cartr it looks like this is working! https://travis-ci.com/sandvige/homebrew-qt4/builds/143793188

[qq42]

Running brew upgrade says:

==> Upgrading 1 outdated package:
cartr/qt4/qt@4 4.8.7_5 -> 4.8.7_6
==> Upgrading cartr/qt4/qt@4
==> Installing dependencies for cartr/qt4/qt@4: [email protected]
Error: [email protected] is already installed from homebrew/core!
Please `brew uninstall [email protected]` first."

However running the suggested brew uninstall [email protected] says:

Error: No such keg: /usr/local/Cellar/[email protected]

How do I get out of this catch-22?

[cartr]

@qq42 That is a good question, and I don't have an answer off the top of my head -- sorry! (It may be worth filing a bug against Homebrew/brew, or posting on their forum, or something. This seems like a bug in brew.)

I did find Homebrew/brew#3024 , which suggests using brew uninstall --force [email protected].
