Need help on Cross compiling Qt 5.1.1 on Imx6
-
I changed my configure to
@/opt/gitQt/qt5/qtbase/configure/ -opensource -confirm-license -qt-xcb -make libs -no-pch -opengl es2 -prefix /opt/Qt5.2.1 -device-option CROSS_COMPILE=/opt/Linaro/bin/arm-linux-gnueabihf- -device imx6 -sysroot /opt/rootfs -no-gcc-sysroot -developer-build -no-gtkstyle -xplatform linux-arm-gnueabi-g++@
and that got rid of the target architecture error...
Now this remains:
@Warning: Disabling pkg-config since PKG_CONFIG_LIBDIR is not set.
Note: PKG_CONFIG_SYSROOT_DIR automatically set to /opt/rootfs
The OpenGL ES 2.0 functionality test failed!
You might need to modify the include and library search paths by editing
QMAKE_INCDIR_OPENGL_ES2, QMAKE_LIBDIR_OPENGL_ES2 and QMAKE_LIBS_OPENGL_ES2 in
/opt/gitQt/qt5/qtbase/mkspecs/linux-arm-gnueabi-g++.

edit: stupid question...

Hi tunahammer,
before I started to compile Qt with the help of Yocto, I was trying it in the same you are currently doing and I ran into the same issue.
To make this error disappear, I had to specify inside the make-spec the path to the includes and the library of opengl inside my target sysroot.
After that I was able to get one step further.
Kind Regards

It appears the manufacturer does not include the correct files for opengl in their sysroot for this device. Am I correct in thinking I need to download the source and compile a version of opengl es2 or is this generic enough that I could try to find someone else with a project with these for an imx6 and use theirs?

Hi tunahammer,
you can either use the sysroot which is provided by freescale (on the website under downloads for imx6 - ubuntu), or you could also use the yocto build system to automatically create a sysroot for you.

I tried it both ways and it was working fine.
And yes I think you could also use a sysroot from another project like the wandboard.org which uses the imx6 as well.
See here the important parameters for my build with yocto:
linux-imx6-g++:...
QMAKE_INCDIR_OPENGL_ES2 += /home/linuxdev/DevStuff/poky-dora-10.0.0/fsl-community-bsp-platform/build/tmp/sysroots/wandboard-dual/usr/include
QMAKE_LIBDIR_OPENGL_ES2 += /home/linuxdev/DevStuff/poky-dora-10.0.0/fsl-community-bsp-platform/build/tmp/sysroots/wandboard-dual/usr/lib...
IMX6_CFLAGS = -march=armv7-a -mfpu=neon -DLINUX=1 -DEGL_API_FB=1 -mfloat-abi=hard -DQT_NO_GLIB

I would have never ever found those files Oo
Here they are:

Soilworker,
I'm moving to a new thread since it's probably more fitting, please follow if you can sir!
