Unable to compile simple_playback.c on macOS using GCC? #655

Closed sofakng closed 1 year ago

sofakng commented 1 year ago

I'm running macOS Ventura (13.2.1) and Homebrew (v4.0.10) and I've installed GCC-12 (v12.2.0).

I've downloaded the latest git release of miniaudio (April 1st, 2023) and I'm trying to compile examples/simple_playback.c.

If I compile using clang (/usr/bin/clang, v14.0.0) then it compiles fine. However, if I use GCC-12 it has a lot of errors:

Unfortunately I need to use GCC to compile another project so I can't switch to clang...

mackron commented 1 year ago

Those errors are coming from inside the Core Audio headers. Not much I can do about those. I can see references to code like (^AudioObjectPropertyListenerBlock) - the use of that ^ token is clearly invalid C. It could be an issue with your compilation environment. Perhaps try compiling as Objective-C.

sofakng commented 1 year ago

Thanks for the reply...

However, does miniaudio expect clang on macOS? I understand the errors are coming from macOS headers, but miniaudio supports Core Audio, right? If so, was it tested/developed using clang and not gcc?

For example, I'm trying to compile examples/simple_playback.c using gcc-12 (on macOS) but it fails with many errors.

mackron commented 1 year ago

Yes, Core Audio is supported, and it works fine with Clang (and Xcode). I don't think I've personally tried compiling with GCC on macOS. I'm not doing anything unusual in miniaudio so the miniaudio-specific code should compile clean. If there's errors there I'm happy to fix those, but I'm not spending any time trying to work around invalid C in necessary system headers.

sofakng commented 1 year ago

OK - Thanks for the information and I understand what you're saying.

Are there any alternative audio backends for macOS besides Core Audio?

mackron commented 1 year ago

Not built-in, no. But miniaudio supports custom backends. The custom_backend example implements an SDL backend.

I mean, it would be nice for GCC to "Just Work" on macOS, but it's just not a primary platform for me personally so I tend to not give it as much priority. How did you install GCC? I might be able to see if I can replicate it myself at some point.

sofakng commented 1 year ago

Got it. It looks like your SDL example custom_backend works perfectly. Thanks so much!

I was using GCC v12 installed from Homebrew if you are curious and feel like looking into it. However, I'll go ahead and close this issue. Thanks again so much for the help and for the great project!
