Describe your issue
Cross does not compile an alpine image on x86.
[target."x86_64-unknown-linux-musl"]
image.name = "alpine:edge"
image.toolchain = ["x86_64-unknown-linux-musl", "linux/arm64=aarch64-unknown-linux-musl","armv7-unknown-linux-musleabi"]
pre-build = ["apk add --no-cache gcc musl-dev pkgconfig openssl-dev libc-dev git"]
[target."aarch64-unknown-linux-musl"]
image.name = "alpine:edge"
image.toolchain = ["x86_64-unknown-linux-musl", "linux/arm64=aarch64-unknown-linux-musl","armv7-unknown-linux-musleabi"]
pre-build = ["apk add --no-cache gcc musl-dev pkgconfig openssl-dev libc-dev git"]
env.passthrough = ["RUSTFLAGS","TARGET_CC=gcc"]
[target."armv7-unknown-linux-musleabi"]
image.name = "alpine:edge"
image.toolchain = ["x86_64-unknown-linux-musl", "linux/arm64=aarch64-unknown-linux-musl","armv7-unknown-linux-musleabi"]

I get a lot of this output when I compile my rust app

git checkout armv7/sup
RUSTFLAGS='-C target-feature=-crt-static' cross build --release --target x86_64-unknown-linux-musl

RUSTFLAGS='-C target-feature=-crt-static' cross build --release --target armv7-unknown-linux-musleabi
Additional information / notes
No response
cross compiling with alpine seems to be a bit tricky, we've had some conversations about this in the chat
I don't have much knowledge on how it works, but seems that you need to use different roots and possibly emulation.
I have found this SO post and this wiki page
To me, this suggests that there are no distributed cross-compilers and you need to setup the environment yourself or that you use the same host as the target.
The builds where you use alpine and target = host work fine, the problem is when they don't match, right @SamTV12345?. In the issue you're stating that all your configured targets are broken, but it's only aarch64-unknown-linux-musl and armv7-unknown-linux-musleabi? cross build --release --target x86_64-unknown-linux-musl works for me when using

(above is on a m1 mac, hence the long compile due to emulation, but it shouldn't matter)

Interestingly, using alpine:edge for armv8 doesn't work well, opened #1256 for that
