The PKGBUILD now patches Audacity's sources so Clang can compile it. If you are updating from an older version, you may have to clean your AUR helper's cache (i.e yay -Sc).

I used the commands in the PKGBUILD to compile Audacity by hand so I could see all errors emited by make and clang. It seems it is a error in portaudio-v19, which Audacity vendors:

/home/ongyx/.cache/yay/audacity-git/src/audacity/lib-src/portaudio-v19/src/hostapi/alsa/pa_linux_alsa.c:4377:5: error: cannot jump from this goto statem
ent to its label
    goto end;
    ^
/home/ongyx/.cache/yay/audacity-git/src/audacity/lib-src/portaudio-v19/src/hostapi/alsa/pa_linux_alsa.c:4202:5: note: jump bypasses initialization of va
riable with __attribute__((cleanup))
    pthread_cleanup_push( &OnExit, stream );
    ^

Relevant part of portaudio's code:

    /* Execute OnExit when exiting */
    pthread_cleanup_push( &OnExit, stream );

    /* ... */

end:
    ; /* Hack to fix "label at end of compound statement" error caused by pthread_cleanup_pop(1) macro. */
    /* Match pthread_cleanup_push */
    pthread_cleanup_pop( 1 );

    PA_DEBUG(( "%s: Thread %d exiting\n ", __FUNCTION__, pthread_self() ));
    PaUnixThreading_EXIT( result );

error:
    PA_DEBUG(( "%s: Thread %d is canceled due to error %d\n ", __FUNCTION__, pthread_self(), result ));
    goto end;
}

The pthread_cleanup_push macro actually has a __attribute__((cleanup)) in it.

It is not guaranteed that pthread_cleanup_pop will run because goto end only occurs in specific cases. Clang throws a hard error on this, but gcc won't.

This error was reported on upstream portaudio too.

The fix is to just move pthread_cleanup_pop before the end: goto label. I tried this and Audacity compiles sucessfully. I'll test out this patch on the PKGBUILD.

EDIT: I'll also open a PR to upstream to fix this.

This package does not build and audicity-3.0.2 package either. The error I'm getting now is:

When I updated on 22 May I was working since several days, broke the day after -_-

I have added conan to makedepends, however the build still fails at about 40%

add conan to the build-dependencies
