Bug 926059 – cross-x86_64-w64-mingw32/gcc: fails to compile with "The directory that should contain system headers does not exist: /usr/lib/gcc/x86_64-w64-mingw32/13/include" (make[2]: *** [Makefile:3362: stmp-fixinc] Error 1)

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Abhinav 2024-03-03 01:29:52 UTC]

Mingw32 build of GCC on Gentoo LiveGUI (with no use flag changes) fails in the same way as #905118.

Reproducible: Always

Steps to Reproduce:
1. Start Gentoo LiveGUI
2. webrsync (tested on Mar 2 2024)
3. Add crossdev overlay
4. crossdev --target x86_64-w64-mingw32
Actual Results:  
Build fails with "The directory that should contain system headers does not exist: /usr/lib/gcc/x86_64-w64-mingw32/13/include" (make[2]: *** [Makefile:3362: stmp-fixinc] Error 1), log attached.

Expected Results:  
Builds sucessfully.

[Comment 2 Sam James 2024-03-03 01:38:43 UTC]

For targets where we have to run fixincludes (only two, per the other bug), I guess we sometimes need https://gitweb.gentoo.org/repo/gentoo.git/tree/sys-devel/gcc/files/gcc-13-fix-cross-fixincludes.patch?id=0b75d3ce0bae8240c28c6a8f191f5130548f8475

What I don't yet get is why nobody else reported this until now...

I guess because there are few(er) MinGW crossdev users now that we have dev-util/mingw64-toolchain.

Yeah, possible. But all of the reporters in the other bug were using mingw via cross, right?

[Comment 5 Sam James 2024-03-03 01:48:59 UTC]

(and they all successfully emerged it after that fixincludes eclsass change)

My guess would be that a successful crossdev build installs headers to /usr/lib/gcc/x86_64-w64-mingw32/13/include so they are available for subsequent upgrades but not the initial install. And those users may have done the initial install at a time before the patch. I don't know enough about crossdev to confirm this though (but I can see that there are headers in /usr/lib/gcc/x86_64-w64-mingw32/13/include in backups of a system that had a MinGW toolchain installed).

Or, at least, at some point in the past it did.

[Comment 8 Sam James 2024-03-03 02:20:37 UTC]

That sounds like a reasonable theory and it's aligned with my suspicion about the original patch we reverted. I think it doesn't take into account the staged build and looks at the real system.

[Comment 9 Chris Henhawke 2024-03-03 14:38:07 UTC]

> What I don't yet get is why nobody else reported this until now...

FWIW, when I hit 925204 it was on an existing install, this sounds like a new install.  I had some free time, so I tried recompiling my existing install again (emerge -1v cross-x86_64-w64-mingw32/gcc), and it seems to build fine... or at least it seemed to get past the point where I had issues the other day... (tree revision be549bab0f447ff65332e4bbdd185d3e95a83fb1)

Unpacked stage3-amd64-openrc-20240229T194908Z.tar.xz to a new chroot, copied /etc/portage to the new chroot and installed crossdev.  Build failed using -j4, so I tried again with -j1 and it also failed as reported. (crossdev -t x86_64-w64-mingw32)

Back on the existing install, -j1 build was successful, so this only seems to affect new installs.

Sorry I wish I could be of more help.  Cheers

I've run into this issue in an existing installation a few days ago, so there's probably something else going on here (is this the right bug?) As to why nobody reported it sooner, mingw64-toolchain was working just fine, and I blamed it on non-standard compiler/flag settings.

Provided patch fixes the issue.

[Comment 11 Sam James 2024-03-07 18:34:59 UTC]

I don't anticipate having time for the next few days to look into this properly, so I'll put back the old patch.

    Revert "sys-devel/gcc: drop obsolete cross fixincludes patch for 13"
    
    This reverts commit 456eee6e374b50a4d9108a642ca29c5573ac5cb8.
    
    Restore the fixincludes revert. The situation has improved a bit though,
    because we now only run fixincludes when it's truly needed, so having
    this patch is less risky to begin with.
    
    Caveat emptor for trying to remove this in future: make sure to test
    clean builds without mingw already built, and with.
