addpkg(pixi): v0.63.2

[SekaiArendelle]

• Use pre-compiled static musl binaries for aarch64 and x86_64
• related to [Package]: pixi #22227

[robertkirkman]

Precompiled executables are not ideal for Termux.

I recommend that instead, you try to work on this error in the command cargo install pixi:

error[E0277]: the trait bound `Utf8TypedPath<'_>: From<Utf8TypedPath<'_>>` is not satisfied

I will give it a try

[SekaiArendelle]

https://pixi.prefix.dev/latest/installation/#install-from-source seems we shoud compile and install it but not from crates.io.

[robertkirkman]

Oh you're right, that's interesting, they do say that

Also, some research suggests that pixi is a variant of, or alternative implementation of, conda. Because of that, it seems like pixi is probably unlikely to work properly on Android, even when its package is compiled from source, because of similar reasons to conda when conda was last tried:

• conda package manager #464

however, it's a new project and might be different from the old conda, so it's worth a try to at least test and see what happens!

I am doing something else at the moment but in a while I will try to help compile this.

[SekaiArendelle]

Yes, you are right. Only a very limited number of packages are available for Android.

[robertkirkman]

I'll show how far I was able to get after trying to compile pixi for a while,

I did this:

git clone https://github.com/prefix-dev/pixi.git
cd pixi
# I applied this patch and also I applied a similar patch to the dependency crate 'rattler_pty'
git apply -v << 'EOF'

When I did that, pixi compiled, but, when I tried running it using the last two commands at the bottom of my list, I see these errors now:

Help: This platform (unknown) is not supported. Please run the following command to add this platform to the workspace:

	pixi workspace platform add unknown

and

Error:   × 'unknown' is not a known platform. Valid platforms are 'noarch', 'unknown', 'linux-32', 'linux-
  │ 64', 'linux-aarch64', 'linux-armv6l', 'linux-armv7l', 'linux-loongarch64', 'linux-ppc64le',

it seems like somewhere there is this list of supported platforms, and Android is not in it already, so to make pixi run on Android it would be necessary to find that and make further changes.
