Cross compile from Ubuntu Desktop to Raspberry Pi 2

@hubaiz Looking promising!
I just wonder, the second script, is there anything else i need to change than the path to tools and sysroot when targeting qt5.8 and raspberry 3?i changed the paths and ran the script in qtbase but got errors.

I ran into this a few weeks ago when upgrading from Qt 5.7 to 5.8 and following the wiki's instructions. I added
-skip qtwebengine -no-icuwhen I ran./configurebecause I don't need those features in my app and it worked fine after that. -

ERROR: Unknown command line option '-skip'.Have tried to put in the beginning and in the end of the script, but i guess as long it doesn't know what it is that does not matter.

@Fifkie Can you show your script?

@jsulm Sure!
It's this script:
#!/bin/sh ./configure -opengl es2 -device linux-rasp-pi-g++ -device-option CROSS_COMPILE=/home/marco/Qt/5.3/tools-master/arm-bcm2708/arm-rpi-4.9.3-linux-gnueabihf/bin/arm-linux-gnueabihf- -sysroot /home/marco/Qt/5.3/sysroot -opensource -confirm-license -optimized-qmake -reduce-exports -release -make libs -prefix /usr/local/qt5pi -hostprefix /usr/local/qt5pi -vWith the "-skip qtwebengine -no-icu" added. I've tried right in the beginning after ./configure, in the end and after "-opensource". Neither worked.

I was having the same issue and reconfigured with just the -no-icu flag and everything worked fine (I use qtwebengine in my app) my config string is as follows...
./configure -release -opengl es2 -device linux-rasp-pi2-g++ -device-option CROSS_COMPILE=~/raspi/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian-x64/bin/arm-linux-gnueabihf- -sysroot ~/raspi/sysroot -opensource -confirm-license -prefix /usr/local/qt5pi -extprefix ~/raspi/qt5pi -no-icu -hostprefix ~/raspi/qt5 -v

But I got Kukkimonsuta's tutorial working for me so i got it working now. For anyone else looking for a solution just follow the steps at https://github.com/Kukkimonsuta/rpi-buildqt . Only thing i had to change was with one of the scripts i got an error that it didn't have the permission to sync one folder from the RPI. So in the sync script i just added
--exclude 'vnc'in the rsync under "== Copy /usr/lib =="
That's because it wouldn't sync the vnc-folder. -

For my project I wrote a couple Ansible playbooks to automate the process, so it's easy to upgrade to new versions of Qt in the future. Unfortunately I can't share them at this point, but I may later if I clean them up.
