I also tried to create a small Dockerfile to extract the garage binary:

It's NOT caused by missing config:

Can you strace your invokation of Garage to see what file it is trying to access?

Something like:

strace -yy /bin/garage

This is what I have on arm64 with the binary from https://garagehq.deuxfleurs.fr/_releases/v0.6.0/armv6l-unknown-linux-musleabihf/garage

$ strace -yy /bin/garage
execve("/bin/garage", ["/bin/garage"], 0xfffffb74c0a8 /* 32 vars */) = -1 ENOENT (No such file or directory)

Yes, I'm getting the same strace on the Pi.

Could this be relevant?

Oh yeah, ln -s /lib/ld-linux-armhf.so.3 /usr/lib/ld.so.1 fixed it, but it doesn't feel right, lol

No, that definitely shouldn't be the solution! Theoretically all our builds are statically linked so I'm surprised they still depend on ld.so. Maybe @quentin could shed some light on the issue as he is the one who designed the build system?

I am using Nix toolchains to get statically compiled binaries with musl. For armv6+armv7, I am using this toolchain: armv6l-unknown-linux-musleabihf. We can compare it to amd64 where we have: x86_64-unknown-linux-musl.

But when we compare the ouputs, it seems that arm is dynamically linked while amd64 is not, despite the only difference between them being the target above.

$ file garage_amd64
garage_amd64: ELF 64-bit LSB pie executable, x86-64, version 1 (SYSV), static-pie linked, not stripped

$ file garage_arm
garage_arm: ELF 32-bit LSB pie executable, ARM, EABI5 version 1 (SYSV), dynamically linked, interpreter /usr/lib/ld.so.1, not stripped

$ file garage_arm_0.4.0
garage_arm_0.4.0: ELF 32-bit LSB pie executable, ARM, EABI5 version 1 (SYSV), dynamically linked, interpreter /usr/lib/ld.so.1, not stripped

I will get a more in-depth look at this issue next week and fix it. I will probably add a check to ensure that the generated build is, indeed, statically compiled, for all architectures.

For now the only thing I can confirm is that's a bug on our side and we will try to fix it as soon as possible. Thanks for reporting it.
