Any updates on this?

[blicknix]

Any news on this?
Are there any dependencies we have to install on alpine, which are not documented?

[trmartin4]

@mbl-35 due to some updates in our CLI dependencies, we believe that this issue may be resolved. Could you confirm if it has been fixed? Thank you for your help.

hello @trmartin4 . tested on fresh alpine:3.20 and alpine:3.22.1 uptodate.
Have same pbs. need to install libgcc, libstdc++, gcompat and libc6-compat but still have this lines;

I just tried on alpine 3.22 and it indeed does not work, even with gcompat and fully updated musl.

It needs to be compile for Musl instead of using gcc.

Legacy LFS64 interfaces (e.g., stat64, posix_fallocate64) are no longer provided under _GNU_SOURCE, only under _LARGEFILE64_SOURCE, and will be removed in the future.

from https://musl.libc.org/releases.html

This occurs because fcntl64 is glibc-specific and not supported by musl, which assumes fcntl is 64-bit by default. Apparently there are already commits that fix this on alpine's gcompat git but it hasn't received a new release in over 2 years so I'm not really hopeful for this

If someone from bw could compile an alpine-compatible version of the cli and officially release it, that would be great

thanks!
