A short howto how to build Qt5 for Freescale i.MX 5x
The original post here is completely outdated!!
Right now you only need a sys root with the GLES headers/libraries in it.
Then configure/build for linux-arm-g++. That's it!
Simple and fun!!
Prerequisites:
A recent ltib envioronment , that you configured and built for your target. You are going to use the rootfs for the Qt5 dependencies. If you at a later stage want to build webkit you also need libicu for your target installed in your rootfs. If you want GLES functionality EGL and GLES2 needs to be in the rootfs.
1) Get the latest Qt5 from the official GIT repository:
git clone git://gitorious.org/qt/qt5.git qt5
2) Create a build directory somewhere , for example :
/home/micken/qtbuild
3) Go to the your newly cloned Qt5 tree and do the following command:
perl init-repository
This will download the sourcecode.
3) Inside the sourcetree you can find a directory called qtbase.
This directory looks like the root directory of a Qt4x source tree.
4) Find the file mkspecs/devices/linux-imx6-g++/qmake.conf inside qtbase.
5) Edit it to find your toolchain and rootfs. In order to build for i.MX
5x you need to comment out EGLFS_PLATFORM_HOOKS_SOURCES.
Note the configure line at the top of the file and copy it to a textfile
and modify it to reflect your environment.
6) Go to your created build directory and issue the configure script from the
with the textfile you created. ( sh /path/to/qt5/qtbase/yourtextfile )
7) After this you should be able to just do make;make install
8) The other libraries / examples can be built by using your installed Qt
make sure it uses the qmake from the installed Qt.
9) To install Qt5 on target , make a directory named the same as your
installation path (important) and copy the lib and plugins directories to it.
10) Try some examples ,you can start them like this:
./hellogl_es2 -platform eglfs.
Have fun with Qt5. I am working on a new graphics platform plugin that will integrate 2D and 3D on the i.MX. More about that later.
