switchaudio-osx @1.2.2: fatal error: 'CoreAudio/AudioHardwareBase.h' file not found

[RobK88]

The port switchaudio-osx fails to build. I see that the MacPorts build bots are also unable to build switchaudio-osx on Snow Leopard through to Big Sur. I tried building using other compilers. It made no difference.

According to the developer's website, switchaudio-osx should build on Lion and greater.

It looks like there is a missing header -- CoreAudio/AudioHardwareBase.h

See below and the attached main.log

Please report the bug to the developer so they can fix it.

I agree the project's readme says it was tested on 10.7 and later but it appears not to have been tested on macOS versions that old for some time given that there is another bug already filed about a different build failure that affects 10.14.

[RobK88]

I agree Ryan. It looks like the readme.md file on the project's GitHub page is out of date since the latest source code now relies on new symbols that are only available on macOS 12 Monterey and later.

P.S. I did report the bug to the developer. But I think the real bug is with the readme.md file which should be updated to indicate that the program now only runs on macOS12 Monterey and later.

[RobK88]

Please note that version 1.1.0 of switchaudio-osx still builds on Lion and presumably on all macOS versions. See below. Versions 1.2.0 and newer do not build.

Maybe we should create a switchaudio-osx-legacy port for the older macOS's and restrict this port to Monterey and newer?

Or make the single switchaudio-osx port install 1.1.0 when building for Big Sur and earlier and 1.2.0 for Monterey and later. It would probably want to decide based on ${macosx_deployment_target} rather than ${os.major}.

I don't like the idea of a separate port with "legacy" in the name. It's not very specific. What happens if version 1.3.0 drops support for Monterey? Do you then create a third port called switchaudio-osx-not-quite-as-legacy for 1.2.0? If separate ports need to be created for separate versions, the best idea is usually to put the relevant portion of the version number into the port name.

There don't appear to be any ports that depend on switchaudio-osx so either strategy could be used, but in the case of ports that are used by other ports I prefer not having separate ports because it makes it easier on all the other ports. Separate ports require those other ports to know on which OS versions to depend on which port.

[RobK88]

@Ryan -- interesting idea -- using a single port for the current version and the legacy version. But wouldn't that confuse users? When one gets info on the port (e.g. port info switchaudio-osx), one will see only the current version listed. And when they install the port on an old Mac, they may think they are running the most recent version when in fact they are not.

Perhaps having separate ports with the version number in the port name makes the most sense.
