Need help on Cross compiling Qt 5.1.1 on Imx6

[tunahammer]

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++.

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
Soilman

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.

http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=i.MX6Q&fpsp=1&tab=Design_Tools_Tab#

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

[tunahammer]

I would have never ever found those files Oo

Here they are:
http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=i.MX6Q&fpsp=1&tab=Design_Tools_Tab#
Software Development Tools (15)
Set of applications for the Linux L3.0.35_4.1.0 BSP

Soilworker,

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

I setup bitbake and openembedded.
which cross compiler is recommend?
where to get recipe angstrom-qt-x11-image

I am newie. Please kindly assist.

Hi

I am running on sabrelite.
is it possible to setup qt creator to send in binary on the video files.
I believe it is tougher to cross compile qt onto the target, because i heard need Qt runtime environment installed

[houmingc]

I downloaded ARM cross compiler, QtCreator and qmake for development and buildroot for deployment. I have problem in qmake configuration,

ARM compiler is tested working. Can guide me step by step.bq.
