build.log (amd64, 4.10.4)

Same here on amd64 musl/clang.
Comment 3 ernsteiswuerfel archtester 2023-07-03 10:55:19 UTC
Does not seem to be a clang-16 issue, happens with clang-15 too on my machine.
Comment 4 Alex Pushkin 2023-07-03 18:01:42 UTC
The same with my machine:

gtk-4.10.4 build error
Comment 6 unhappy-ending 2023-07-06 17:07:06 UTC
I can confirm the same error. However, this doesn't happen in gtk-4.10.3, which compiles fine. Something changed on the point release to cause this.
Comment 7 unhappy-ending 2023-07-06 17:16:56 UTC
I tried to use -fuse-ld=bfd to see if I got the same error and for some reason the build system is completely ignoring it and I'm still getting ld.lld: error: target emulation unknown: -m or at least one .o file required. Not sure what's going on with that, but that shouldn't happen.

build system ignores -fuse-ld

See build flags contain -fuse-ld=bfd, but still gets ld.lld error.
Comment 9 Chris 2023-07-07 16:29:55 UTC
Interestingly I also added the gui-libs/gtk build to my GCC override profile (I'm on LLVM) in an attempt to work around the problem, and I run into the same issue - even with the environment settings forcing GCC toolkit, the ebuild seems to ignore it and forces a build against LLVM.

What happens when you use GCC but pass -fuse-ld=lld to your LDFLAGS?

Sadly it's the same behavior. 

Here's the env file that I was pointing my compiler override at...

CC="gcc"
CXX="g++"

AR="${CHOST}-ar"
NM="${CHOST}-nm"
RANLIB="${CHOST}-ranlib"

COMMON_FLAGS="-O3 -march=native"
CFLAGS="${COMMON_FLAGS}"
CXXFLAGS="${COMMON_FLAGS}"
LDFLAGS="-Wl,--as-needed -fuse-ld=lld"

Same issue for me. Funny, 4.11.4 compiles just fine :( Must be something in the 4.10.4 build system. 

For a quick test I unmerged lld from my system and then used -fuse-ld=bfd and it compiled without a problem. Really not sure what's going on. I'm just going to mask 4.10.4 since the next release doesn't have the issue.

That's not unexpected at all, as it got fixed upstream in 4.11.x.

Or, rather, it's workedaroundededed as it still needs Binutils.
Comment 15 Brahmajit Das 2023-07-22 14:21:08 UTC
Seems like it's fixed in gui-libs/gtk-4.11.4
Comment 16 immolo 2023-10-09 14:56:58 UTC
This came up as a support question in Discord today reported by who.

I've confirmed the issue now only exists on stable gentoo llvm systems as using gui-libs/gtk-4.12.5 will solve the solve the issue however a further test is required if the STABLEREQ will be enough to close this in Gentoo or if it's just a workaround needing binutils as Sam highlighted.

Steps to reproduce now are as follows:

1. Setup new llvm stage3
2. emerge -va gui-libs/gtk

Result:

[308/946] /usr/lib/llvm/16/bin/ld.lld -z noexecstack -r -b binary gtk/gtk.gresource -o gtk/gtkresources_blob.o
FAILED: gtk/gtkresources_blob.o 
/usr/lib/llvm/16/bin/ld.lld -z noexecstack -r -b binary gtk/gtk.gresource -o gtk/gtkresources_blob.o
ld.lld: error: target emulation unknown: -m or at least one .o file required

Workaround currently tested as works for me:

1. add `=gui-libs/gtk-4.12.5 ~amd64` to /etc/portage/package.accept_keywords
2. emerge -va1 =gui-libs/gtk-4.12.5
Comment 17 ernsteiswuerfel archtester 2024-01-12 16:04:12 UTC
Fixed in gtk-4.12.4.
Comment 18 Mart Raudsepp gentoo-dev 2024-02-11 14:02:18 UTC
So can this bug and the associated GitHub PR be closed now?
