REGRESSION: kwindowsystem:x64-linux:

/usr/bin/ld: /mnt/vcpkg-ci/installed/x64-linux/debug/lib/libQt6WaylandClient.a(qwayland-wayland.cpp.o): in function `QtWayland::wl_registry::wl_registry(wl_registry*, unsigned int, int)':
/mnt/vcpkg-ci/b/qtbase/x64-linux-dbg/src/plugins/platforms/wayland/qwayland-wayland.cpp:21: multiple definition of `QtWayland::wl_registry::wl_registry(wl_registry*, unsigned int, int)'; src/platforms/wayland/CMakeFiles/KF6WindowSystemKWaylandPlugin.dir/qwayland-wayland.cpp.o:/mnt/vcpkg-ci/b/kwindowsystem/x64-linux-dbg/src/platforms/wayland/qwayland-wayland.cpp:20: first defined here

I don't see how this could possibly have passed in previous CI runs (an installation order issue?)

REGRESSION: qtmultimedia:*-android:

ld.lld: error: unable to find library -lxml2
ld.lld: error: unable to find library -licuuc

It's either a bug in Qt's FindFFmpeg.cmake which has some sketchy pkg-config parsing code, or a bug in ffmpeg exported pkg-config. Added arm-neon-android and x64-android to the ci.baseline.txt because arm64-android is already there.

Current master for qtmultimedia[core,ffmpeg,qml,widgets]:x64-android so I would suggest to dive deeper instead of baseline.

kwindowsystem:x64-linux:

Is probably a bug introduced by Qt since the sources seems to get generated and then compiled.

Do you also have logs for arm64-android? I wonder why is it in the ci.baseline.txt and others are not.

kwindowsystem:x64-linux: Is probably a bug introduced by Qt since the sources seems to get generated and then compiled.

Yeah but I don't see any related changes. And since both libQt6WaylandClient.a and KF6WindowSystemKWaylandPlugin.so try to link qwayland-wayland.a the only idea I have right now is that the linker was quietly ignoring one of the copies but doesn't do that anymore.

Alexander Neumann (Neumann-A) · 2026-08-20T21:22:19Z

KF6WindowSystemKWaylandPlugin.so

qwayland-wayland.a is itself a plugin? KF6Windows should probably not build an *.so or not link the plugin

Osyotr (Osyotr) · 2026-08-20T21:38:08Z

qwayland-wayland.a is itself a plugin?

It's an object file produced from the autogenerated qwayland-wayland.cpp in both projects.

I've reproduced the error locally but I don't see any differences in build process between 6.11.1 and 6.11.2.

Osyotr (Osyotr) · 2026-08-27T15:56:39Z

The commit that causes the regression is qt/qtbase@db5392c.

kwindowmanager uses protocols from /usr/share/wayland/.
qtbase uses its own vendored copy of protocols in src/3rdparty/wayland/protocols/wayland/.
They are already quite different in 6.11.1 so I don't see why it would suddenly break after a minor change.

Osyotr (Osyotr) · 2026-09-11T08:58:01Z

Alexander Neumann (@Neumann-A) any idea what might be wrong?

Looks just like a missing include. Locate the header, find the qt target to depend upon and simply link against it?

It was my failed attempt to fix the issue, the real error is here:
https://dev.azure.com/vcpkg/public/_build/results?buildId=136342&view=logs&jobId=f79cfdd7-47a8-597f-8f57-dc3e21a8f2ad&j=f79cfdd7-47a8-597f-8f57-dc3e21a8f2ad

This reverts commit d1d8c56.

Andrew Tribick (ajtribick) · 2026-09-20T06:52:54Z

Seems that Wayland is rather hostile to static linking - the x64-linux-dynamic triplet works fine, presumably because the Wayland functions aren't marked for export, but static linking gives you nowhere to hide.

The qt6 ports install their version of the wayland.xml file to share/qt6/wayland/protocols/wayland/wayland.xml

Adding the following to the kwindowsystem portfile.cmake appears to fix the build:

vcpkg_replace_string(
    "${SOURCE_PATH}/src/platforms/wayland/CMakeLists.txt"
    "\${Wayland_DATADIR}/wayland.xml"
    "???/share/qt6/wayland/protocols/wayland/wayland.xml"
)

Not sure what ??? should be there (tested locally by just hardcoding the absolute path there), presumably there's some obvious CMake variable I can't find in the docs right now.

(This does feel somewhat hacky, probably the proper way to do things is to de-vendor the Wayland protocols, but this would also require the wayland port to install a known version of the wayland.xml protocol file even when X_VCPKG_FORCE_VCPKG_WAYLAND_LIBRARIES is not set)

Osyotr (Osyotr) · 2026-09-20T21:07:35Z

Hmm couldn't repro qtmultimedia failure locally with the following command:

./vcpkg install qtbase[core] qtbase[core,thread]:x64-linux-release qtmultimedia[core,ffmpeg] ffmpeg libsndfile[core] dbus[core]:x64-linux-release --triplet=x64-android --host-triplet=x64-linux-release

Billy O'Neal (BillyONeal)

Thanks for the update!

Given that the existing ci.baseline.txt skip for arm64-android was here and the discussion suggests that the behavior may be nondeterministic I'm going to take this.

Sorry, I tried :/. Will check again in the morning or if anything breaks go for it

Billy O'Neal (BillyONeal)

Thanks! And yes, I put that patch back, I thought it was added here. Megaderp.

Andrew Tribick (ajtribick) · 2026-09-24T08:24:06Z

I wonder if bumping vcpkg-tool-nodejs would fix these random qtwebengine failures?

Billy O'Neal (BillyONeal) · 2026-09-24T20:01:51Z

I don't think they use that?
