I an developing for an Odroid XU4 which is ARM V7 32 Bit Ubuntu MATE. I know that I could develop on the embedded device directly, but this is not a suitable setup for my Team. Thus I would like to develop on my 64 Bit Linux maptop and cross compile for the 32 Bit armV7. I use QtCreator for development
What I did so far to make the cross compile work is
- compiled all libraries that I need (e.g. openCV) on my Odroid and copied them to my Linux 64Bit to use for cross compile
- downloaded the correct CrossCompiler (gcc-linaro-7.1.1-2017.08-x86_64_arm-eabi/bin/arm-eabi-g++)
- compiled qt 5.9 on the odroid and copied to the linux machine to be used for cross compile
Now I setup a new Kit in qtCreator and define the correct qmake location. This is when I get the error, that the architecture is false (naturally since I compiled it on a 32 Bit)
So the question is, how do I have to build qt in order to us it for cross compiling an app for the target platform armV7 (32 bit) on a 64 bit linux laptop
Any help is very much appreciated.
