[meta-freescale] qt5 xcb gles2

[Benjamin Federau]

Hello,

I followed your discussion about qt5, xcb and gles2 on an i.MX6 board.

Finally the workaround/hack by setting the VisualId hard to "33" helped me a lot
to get Qt5.1.1 running on my SabreLite SD board. Thanks for that. :)

First, I have to say that I use Ubuntu 12.04 instead of Yocto on my board. But I
use the same graphic libs and dev headers version (3.5.7-1.0.0) as in the next
branch of the meta-fsl-layer.

I found out that I could not compile Qt5.1.1 with the
/usr/include/EGL/eglplatform.h header from the Freescale graphic libs package.
When I use this header I run into the following problem.

QT5 make fails on QUrl  - http://qt-project.org/forums/viewthread/25896

If I replace the eglplatform.h with the one from the Ubuntu standard mesa
package the compilation runs through. The issue must be related to the
MESA_EGL_NO_X11_HEADERS macro which is not used inside the Freescale
eglplatform.h file.

My qmake.conf
....
QMAKE_INCDIR           += /usr/include
QMAKE_LIBDIR           += /usr/lib

QMAKE_LIBS_EGL         += -lEGL
QMAKE_LIBS_OPENGL_ES2  += -lGLESv2 -lEGL -lGAL
QMAKE_LIBS_OPENVG      += -lOpenVG -lEGL -lGAL

IMX6_CFLAGS             = -march=armv7-a -mfpu=neon -mfloat-abi=hard -DLINUX=1
IMX6_CFLAGS_RELEASE     = -O2 $$IMX6_CFLAGS
QMAKE_CFLAGS_RELEASE   += $$IMX6_CFLAGS_RELEASE
QMAKE_CXXFLAGS_RELEASE += $$IMX6_CFLAGS_RELEASE
QMAKE_CFLAGS_DEBUG     += $$IMX6_CFLAGS
QMAKE_CXXFLAGS_DEBUG   += $$IMX6_CFLAGS
....

and my configure command

./configure -v -opensource -confirm-license -no-pch -opengl es2 -qpa xcb -nomake
examples -nomake tests -platform linux-imx6-g++ -prefix /opt/qt5.1.1


So I wonder how you could build qt5.1.1 with the Freescale eglplatform.h.


Any hints are welcome where I could start digging to solve that issue.
