When I added powervr support to Qt I added a powervr virtual package the same as opengl_es or opengl_egl. This allows Qt to not contain anything specific to the hardware graphics package. > endmenu > diff --git a/package/qt/Config.in b/package/qt/Config.in > index 9f6e54d..35e8208 100644 > --- a/package/qt/Config.in > +++ b/package/qt/Config.in > @@ -281,6 +281,14 @@ config BR2_PACKAGE_QT_PHONON_BACKEND > help > Build the platform Phonon plugin. > If unsure, say n. > + > +config BR2_PACKAGE_QT_OPENGL_ES > + bool "OpenGL ES v2.x support" > + depends on BR2_PACKAGE_HAS_OPENGL_ES > + depends on BR2_PACKAGE_HAS_OPENGL_EGL > + help > + Enable the OpenGL ES v2.x support. > + > endif > > config BR2_PACKAGE_QT_DBUS > diff --git a/package/qt/powervr.ini b/package/qt/powervr.ini > new file mode 100644 > index 0000000..57863eb > --- /dev/null > +++ b/package/qt/powervr.ini > @@ -0,0 +1,2 @@ > +[default] > +WindowSystem=libpvrQWSWSEGL.so.1 > diff --git a/package/qt/qt-eglwsegl-use-system.patch b/package/qt/qt-eglwsegl-use-system.patch > new file mode 100644 > index 0000000..5464fdc > --- /dev/null > +++ b/package/qt/qt-eglwsegl-use-system.patch > @@ -0,0 +1,802 @@ > +Patch to remove obslete powervr headers and instead use the headers provided > +on the system. > + Is this really necessary. When I got this working I instead used the variables provided by Qt to point it to the hardware specific headers. The code looks like: +ifeq ($(BR2_PACKAGE_QT_GFX_POWERVR),y) +define QT_CONFIGURE_POWERVR + $(call QT_QMAKE_SET,QMAKE_INCDIR_OPENGL_ES2,$(STAGING_DIR)/usr/include/OGLES2,$(@D)) + $(call QT_QMAKE_SET,QMAKE_INCDIR_EGL,$(STAGING_DIR)/usr/include/OGLES2,$(@D)) + $(call QT_QMAKE_SET,QMAKE_INCDIR_POWERVR,$(STAGING_DIR)/usr/include/pvr2d $(STAGING_DIR)/usr/include/wsegl,$(@D)) +endef +endif I have this working with both TI and freescale hardware. I'll check what state my patches are in and if they need rebasing against master and then I can post them if people would be interested.
