Description Ville Syrjala 2021-03-01 22:13:28 UTC
I finally got fed up with distcc i686 cross compilation being miserable, and I tracked it down to some silly stuff that removes the "-pc" from the host tuple: https://github.com/distcc/distcc/blob/033630dfe00951d9511c8c2a3dc17f3c9328cf58/src/compile.c#L593
It then goes to look for an executable in PATH that matches the mangled name, which fails since the executable has the "-pc" in the filename.

In fact looks like it's a known issue upstream refuses to fix because they claim it would break Debian/etc.: https://github.com/distcc/distcc/issues/377
I don't have any Debian/etc. installations around to check so won't bother reopening the upstream argument.

I'm now carrying a patch on all my i686 machines to skip that crap. I would suggest such a patch should be part of the actual ebuild.

Reproducible: Always

I agree with you and left an angry comment there.  Yes, distcc is a really bad project.  It's the kind of upstream that fixes only bugs that affect their corporate sponsors/employers, and don't care that things are broken for a lot of people (see distcc-pump).

Could you make a patch for me to apply?
Comment 2 Maciej Mrozowski gentoo-dev 2021-03-01 23:52:57 UTC
Did you try setting that DISTCC_NO_CROSS_REWRITE thingy from https://github.com/distcc/distcc/commit/2b160f3d20bc235c02c3b3da89d02a52509768e8 ?

We want it to rewrite, not prevent it from rewriting.

[PATCH] distcc: fix i686 cross compile

This is the patch I threw into /etc/portage/patches on my i686 machines.

Comment 6 Ville Syrjala 2023-09-26 14:20:15 UTC
This broke again because the patch was not included in the distcc-3.4 ebuild for whatever reason.

Apparently upstream has finally come up with a fix for this:
https://github.com/distcc/distcc/commit/850db9eec0d5dd7f47ade8ffca91b679081f6d85

Tested that one here and it works too. So please either pick that up, or reinstate the original hack patch.
