Cross Compiling Qt for arm
-
Hello,
I am struggling with cross compiling Qt to be able to run on an Arm Beagleboard-xM running Ubuntu 11.10. I have the armel flavor cross compiler installed on my host machine(also Ubuntu 11.10).
The project seems to configure, but when I attempt the make command, there is usually a file that it cannot find, causing the build to fail. This most recent build attempt was that it cannot find QtGui.
I think I have installed the cross compiler as well as modifying the Qmake.conf to point to the cross compiler.
Here are a few specific details:
My ./configure options are:
./configure
-prefix /opt/qt-arm-bbd
-xplatform /qws/linux-bbd-g++
-embedded arm
-opensource -confirm-licensei get this error: (sorry about the formatting, I don't know what else to do)

make: *** [sub-gui-make_default-ordered] Error 2According to the error, the compiler could not find the QtGui file, I am not sure why it can't, i havent done anything but change the qmake.config file and then do ./configure then make, it can't seem to make it past this.
Thank you for your help. I am new to Qt and to this kind of embedded programming, so I am still learning.

notice that its missing the pre-compiled header of QtGui.

Can you elaborate?
these are the exact steps i have done:
I downloaded the qt-everywhere-opensource-src-4.8.4.tar.gz from the qt website.
I unpacked it, copied the qmake and edited it to used the arm-gnueabi cross-compiler./configure [options]
makeam i missing some other files?

I suggest trying to backup your mkspec, remove the whole tree unpack a clean one and then start over.
