So, I don't have much experience with musl, but my understanding is that libstdc++ has a hard dependency on glibc. It seems there are patched versions out there to make it work, and I guess that is what alpine is using? However, I don't have a patched version to hand. I would guess that the only problem is some missing includes. Is there any chance you'd be interested in trying to figure out which includes are needed and dropping a PR?

jirutka commented 3 years ago

No, libstdc++ does not have a hard dependency on glibc.

I’ve managed to hack it in the way it builds (quick & dirty patch), but it segfaults in ETACalculator::getEta().

When I comment out the invocation of this method, it copies the files and exits successfully. However, I’m not sure if the cause is really in this method or just a coincidence.

You can trivially run Alpine Linux using e.g. https://github.com/alpinelinux/alpine-chroot-install.

wheybags commented 3 years ago

Ah, thanks for all the effort you've put in! I belive the segfault should be fixed now as of https://github.com/wheybags/wcp/commit/fbc63458fc3a9f7dd122429b97072b3863624bde

jirutka commented 3 years ago

Do I understand correctly that the segfault had actually nothing to do with musl or my hackery to get it work? o.O

wheybags commented 3 years ago

Yup!

jirutka commented 3 years ago

Uh, so you haven’t tested copying an empty directory before? It seems that I had a wrong expectation about the quality/maturity of this project. :(

wheybags commented 3 years ago

I had, but with the configuration I had in my IDE when running tests, it didn't error. Also, from the readme:

It's probably not robust enough for daily use just yet.
