[SOLVED] How to handle depends that are met by multiple packages

jansalleine · 2026-07-12 13:31:44

Hi,

I'm trying to figure out how to make a PKGBUILD for my fork of GoatTracker.
ldd output is:

        linux-vdso.so.1 (0x00007f55355bc000)
	libSDL2-2.0.so.0 => /usr/lib/libSDL2-2.0.so.0 (0x00007f5535515000)
	libjack.so.0 => /usr/lib/libjack.so.0 (0x00007f55354d8000)
	libasound.so.2 => /usr/lib/libasound.so.2 (0x00007f55353df000)
	libstdc++.so.6 => /usr/lib/libstdc++.so.6 (0x00007f5533e00000)
	libm.so.6 => /usr/lib/libm.so.6 (0x00007f5533ccd000)
	libgcc_s.so.1 => /usr/lib/libgcc_s.so.1 (0x00007f55341d3000)
	libc.so.6 => /usr/lib/libc.so.6 (0x00007f5533a00000)
	libpipewire-0.3.so.0 => /usr/lib/libpipewire-0.3.so.0 (0x00007f5534103000)
	/lib64/ld-linux-x86-64.so.2 => /usr/lib64/ld-linux-x86-64.so.2 (0x00007f55355be000)

You need Jack2 and ALSA, but it doesn't matter if you use pipewire for everything (like on my system) or pulseaudio + Jack2 or just have plain ALSA and Jack2 installed.
How would this translate into a depends array of the PKGBUILD?
I read something about using SONAME in the Arch Wiki, but didn't really get how to use that.

EDIT:
solution

depends=(
    'sdl2-compat'
    'alsa-lib'
    'jack'
)

Thank you!

Eg https://archlinux.org/packages/extra/x86_64/jack2/ and https://archlinux.org/packages/extra/x8 … wire-jack/ both provide jack and jack2, so you can just depend on that and allow the user to match that provision as they see fit.

I know. That's the point of my question.
But how do I put that in the depends array? Just add both?

depends=(
    'jack2'
    'pipewire-jack'
)

?!?

Just depending on jack2 will do, pipewire-jack does provide that dependency.

Thanks. I got it working.

Please always remember to mark resolved threads by editing your initial posts subject - so others will know that there's no task left, but maybe a solution to find.
Thanks.

Okay, solution was to just put 'jack' not 'jack2' or 'pipewire-jack' into the dependencies array.

depends=(
    'sdl2-compat'
    'alsa-lib'
    'jack'
)

Since jack is an existing aur package, you should verify if your application does work with jack installed.

https://wiki.archlinux.org/title/JACK_A … mentations may also be helphul.

It looks to me like you should depend on libjack.so, that provides the most options / flexibility for the user. Explicitly depending on a package name that only exists in the AUR seems odd to me unless you specifically require that AUR package (though this may be a moot point as jack2 provides jack ... but really libjack.so is what is needed and all of the options provide this).

If you take that route, consider following this packaging guidance.

To not match sonames of a wrong ELF architecture, we need to apply the best practices outlined in the specification's example section on "depending on a soname": https://alpm.archlinux.page/specificati … n-a-soname
Effectively, this usually means to remove the soname dependency from the global `depends` array (it should also not be present in `makedepends` or `optdepends`) and instead add it in an override in the `package` function to the `depends` array, e.g.:
```
package() {
depends+=(example libexample.so)
}
```
