Description Yaroslav Isakov 2022-06-29 18:00:24 UTC
Hello! Recently I finally managed to delete libX11/libxcb from my system. Unfortunately, when I'm building qtwayland, it fails with

compilation terminated.
make[5]: *** [Makefile:540: .obj/waylandeglclientbufferintegration.o] Error 1

I found change in libglvnd https://gitlab.freedesktop.org/glvnd/libglvnd/-/merge_requests/248, but I have libglvnd-1.4.0 installed, which already have updated headers. I've tried to set CFLAGS/CXXFLAGS to -DEGL_NO_X11=true, no success...

Anything else I'm missing?
Comment 1 Andreas Sturmlechner gentoo-dev 2022-07-03 07:13:39 UTC
/usr/include/EGL/eglplatform.h is part of media-libs/libglvnd, Xlib.h is guarded by #elif defined(USE_X11).
Comment 2 Yaroslav Isakov 2022-07-03 08:01:15 UTC
I found that USE_X11 is defined in /usr/include/qt5/QtEglSupport/5.15.4/QtEglSupport/private/qt_egl_p.h, from dev-qt/qtgui-5.15.4-r2. I rebuilt it. just in case - no change
Comment 3 Yaroslav Isakov 2022-07-03 08:18:35 UTC
I think, this upstream commit is needed https://github.com/qt/qtwayland/commit/2dc725c57bb12a99f141b3852f6db516ced1661b
Comment 4 Yaroslav Isakov 2022-07-03 08:21:40 UTC
I've dropped the definition from qt_egl_p.h, and now qtwayland compiles successfully.
Comment 5 Yaroslav Isakov 2022-07-03 08:29:55 UTC
Also, it worked to set CXXFLAGS to -DQT_EGL_NO_X11, and restoring define in qt_egl_p.h

...except that Qt5 does not use CMake at all, so this change is useless without porting it to qmake. The necessary change to qt_egl_p.h in dev-qt/qtgui was backported in commit f9c024984ea21dd5bdee7e45764d041fb6d9ef27 though.

Thanks for pointing out that commit.

Comment 9 Kirill A. Shutemov 2023-01-08 06:53:56 UTC
USE_X11 in qt_egl_p.h is not part of upstream. It comes from patch 0027-Cater-for-upstream-changes-in-eglplatform.h.patch qtbase-5.15.7-gentoo-kde-1.tar.xz. Reverting the patch helps to fix the issue.
