Building against the conan wxWidgets build

Audacity 3 Help Forum macOS
1

Hi,

I’m working on updating the MacPorts port for Audacity, using master/HEAD. So far I’ve managed to build on OS X 10.9.5 using clang-9 and against a system wxWidgets 3.1.4-pre (3.1.3.1373, the latest commit to run on my OS version). I want to provide a port variant that uses Audacity’s own wxWidgets version, and am running into a few issues that suggest that either I’m doing something wrong, or something hasn’t been tested exhaustively:

  1. missing headerfile search directives so the wx headers aren’t found
  2. osx_cocoa-unicode-3.1/wx/setup.h isn’t copied into the appropriate //package install directory
  3. WXOSX_COCOA is not defined
  4. the wx libraries aren’t linked in (at least for the image-compiler target).

So far I have worked around the 1st three issues but I do not yet see how I could handle the last.

Does this ring any bells?

What version of conan are you using? conan unexpectedly released a 2.0 version a few days ago, Audacity still requires 1.x (I think 1.59.0 is the last version)

I noticed, pulled and got the fix (conan isn’t in MacPorts so I’m using whatever Audacity’s buildsystem decides in this matter). That was necessary for my “system wx” build too.

FWIW, I can’t say I like the move to conan over the previous implementation where the configure step was a configure step that didn’t build half the code already, pulling in things like ninja which I already have, and not giving me full control over how dependencies are built.

I got caught by that recently. My workaround was to create a Python virtual environment in the Audacity/ source tree (using pipenv Pipenv: Python Dev Workflow for Humans — pipenv 2023.11.16.dev0 documentation), then specified version “<2” when installing Conan into the virtual environment. I then activated the virtual environment before running the “cmake” configuration.

Dmitri (one of the developers) said that he’s aware of the problem and was working on a fix but that it was more complicated than he expected (that was a week ago). 2 days ago he added a warning in the source code to say:

At this time, Audacity > does not support Conan 2.0> . If you have Conan 2.0 installed, you will need to downgrade to Conan 1.59.0.

The current build system will do a localised install (= under your build dir) of a supported version of conan (1.59 IIRC). So that’s not my problem.

If it helps, here’s the output from my cmake invocation:

Don’t bother, I caved and decided to build audacity-wxWidgets as a system-level build dependency, and to tweak the fix_bundle.py script so it embeds the used libwx libraries into the bundle.

Glad to hear that you found a way.
