Hi Khem,

I added the VC4GRAPHICS line and here is the complete error that I get:


ERROR: Nothing PROVIDES 'virtual/egl' (but /home/gwilson/Qt-5.15.6/Yocto-build-RPi4/sources/meta-qt5/recipes-qt/qt5/qtbase_git.bb DEPENDS on or otherwise requires it)
vc-graphics PROVIDES virtual/egl but was skipped: PREFERRED_PROVIDER_virtual/libgles2 set to mesa, not vc-graphics
opengldummy PROVIDES virtual/egl but was skipped: PREFERRED_PROVIDER_virtual/libgles2 set to mesa, not opengldummy
vc-graphics-hardfp PROVIDES virtual/egl but was skipped: PREFERRED_PROVIDER_virtual/libgles2 set to mesa, not vc-graphics-hardfp
qtglesstream-dummy-client PROVIDES virtual/egl but was skipped: PREFERRED_PROVIDER_virtual/libgles2 set to mesa, not qtglesstream-dummy-client
NOTE: Runtime target 'zint' is unbuildable, removing...
Missing or unbuildable dependency chain was: ['zint', 'qtbase', 'virtual/egl']

Regards,

Greg

that should have worked well for userland recipe to provide it. Maybe
you need to set

VC4GRAPHICS = ""

in local.conf
