[stefson]

hey everyone,

I'm using the cargo-ebuild-0.5.0 from gentoo tree to get a working ebuild for cargo-xbuild. Tried v.0.6.5 and v.0.5.35 from their repo at https://github.com/rust-osdev/cargo-xbuild

cargo-ebuild ebuild gives me a plain segfault, and dmesg is full of these:

tried removing the linking against systems libssh2+libgit2 from the ebuild, to no effect.

[r7l]

I can confirm this issue. Having the same error when trying to create an ebuild for a different project.

[stefson]

can I throw the patch into /etc/portage/patches to test it?

[r7l]

I am not a Rust developer and for this reason i am pretty much stuck with this issue. But /etc/portage/patches is a great idea, if the PR you've provided is working.

Maybe it's a better idea to fill a bug in bugs.gentoo.org instead of here. This is just a Github mirror and i wonder if anyone is actually reading the issues submitted here.

[stefson]

if you're really stuck, there is a secret escape hatch called --noaudit

[stefson]

the patch revendors the crates, therefore its propably going to be a point release

[r7l]

I've figured what the patch is doing. Just wondered how long it might take to end up as an actual release in Portage. I'll try the --noaudit option or might even try to add a the patch to /etc/portage/patches. Thanks allot!

[stefson]

the patch revendors the crates, so you have to take the old ebuild and adapt it accordingly

[r7l]

I got it working. Thanks allot. But i still hope there'll be an updated version of this project soon.

[stefson]

you care to share your new ebuild here?

it should get fixed for the tree in the not to long future, cargo-ebuild is an official gentoo project after all

[r7l]

This is the Ebuild i've created. It's not for this project and i've just used --no-audit and it went through without any issues.

[stefson]

I meant to ask for the cargo-ebuild-0.5.0-r1.ebuild you used, with patch and updated crates to emerge it. Bumped it myself in the evening, now all is fine with the patch indeed.

[r7l]

I didn't change anything to cargo-ebuild and i don't have any Ebuild beside the default one in Portage. Just using --no-audit did the job for me for now.

[gyakovlev]

sorry I was not around, back now. release 0.5.1 will land to gentoo soon.
