meta-qt6 build for x11 fails with qglxconvenience.cpp:282: undefined reference to `glXGetFBConfigAttrib'

[petero3]

Hi, meta-qt6 yocto build fails with qglxconvenience.cpp:282: undefined reference to `glXGetFBConfigAttrib'

local.conf
DISTRO ?= 'fslc-x11'
QT_EDITION = "commercial"
CORE_IMAGE_EXTRA_INSTALL:pn-core-image-minimal += "qtbase"

bitbake core-image-minimal

| /workdir/fslckqt/build/tmp/work/cortexa35-mx8-fslc-linux/qtbase/6.4.1-r0/recipe-sysroot-native/usr/bin/aarch64-fslc-linux/../../libexec/aarch64-fslc-linux/gcc/aarch64-fslc-linux/11.3.0/ld.bfd: src/gui/CMakeFiles/Gui.dir/opengl/platform/unix/qglxconvenience.cpp.o: in function `qglx_surfaceFormatFromGLXFBConfig(QSurfaceFormat*, _XDisplay*, __GLXFBConfigRec*, int)':
| /usr/src/debug/qtbase/6.4.1-r0/git/src/gui/opengl/platform/unix/qglxconvenience.cpp:282: undefined reference to `glXGetFBConfigAttrib'

similar for meta-qt6 6.2.7
when using distro fslc-x11 or distro poky
