Cross-Compile on Banana Pi
-
Hi guys!
I successfully cross-compiled Qt on my Raspberry Pi but due to performance issues I needed to get faster hardware. Therefore I bought a Banana Pi which does the job.
Apparently I'm not able to cross-compile Qt on that device. My host system is Ubuntu 14.04.1 LTS and the Pi runs with Bananian Linux.
I already tried the "Beginners guide":http://qt-project.org/wiki/RaspberryPi_Beginners_guide and used different image files.
Well I guess I'm using the wrong toolchain since I only found the gcc-4.7-linaro-rpi-gnueabihf which is for the Raspberry Pi.Did anyone face the same problems or is there a guide like there is for the Raspberry Pi?
I am very grateful for help or any advice!! :)
Thanks.
Seb

Hi and welcome to devnet,
What error are you getting ?
-
The Banana PI board is similar to Cubieboard2, so you can try "this":http://wickwire2099.blogspot.com/2014/02/qt5-on-cubieboard-a10a20.html tutorial.

Thank you so much for your quick replies.
SGaist:
The errors appear while running the ./configure command with the following parameters:@./configure -v -opengl es2 -device linux-rasp-pi-g++ -device-option CROSS_COMPILE=~/opt/gcc-4.7-linaro-rpi-gnueabihf/bin/arm-linux-gnueabihf- -sysroot /mnt/ban-pi-rootfs -opensource -confirm-license -optimized-qmake -reduce-exports -release -make libs -prefix /usr/local/qt5pi@
The errors itself are as follows (just a small extract):

Thanks for the link. I'll give it a try and get back to you as soon as I tested it. -
-Sorry but I already get stuck after the first few steps.-
-I downloaded all the necessary files like the image file for the BananaPi, the toolchain and the sunxi-bsp.-
-But there is no BananaPi environment selectable for the ./configure command of the sunxi-bsp. This needs to be -modified according to "this tutorial":https://github.com/bananapi-dev/BPi/blob/master/HowToBuild_BPi_image.en.txt .-
-As pointed out in recital 4 the environment needs to be set as follows:-
-$ source bpi_env.sh--But I can't figure out where to get that file..-
-Does it work with the "cubietruck" or "cubieboard2" entry as well?-NVM - got that one working!
-
Well, I don't find any rootfs for the BananaPi. In particular, for the Bananian Linux which is a debian based image.
Do you have any suggestions where I can get those since the "Linaro Releases":https://releases.linaro.org/ site doesn't provide it?
