Cross Compiling Problem for Apalis-TK1 (qt-qml)

aktay

Hi all,
I am build qt cross compiling for Nvidia Toradex Apalis-TK1. I need to run a qml application on Apalis-TK1. The QtBase modules work correct.

I am getting the following error when doing qmake for Qtdeclarativ. (-b 5.7)

Hi,

There seem to be a mismatch somewhere. You are writing that you are building Qt 5.7 however you seem to try to build the module with Qt 5.3.3.

aktay

@SGaist
Thank you for your reply.Sorry, I got the wrong screen display.
I install modules as follows.

git clone https://github.com/qt/qtdeclarative.git -b 5.7
git clone https://github.com/qt/qt5.git -b 5.7

The correct output is as follows.

You should clone from https://code.qt.io which is the official repository. Github is just a mirror.

Why are you cloning both Qt5 and QtDeclarative ?

aktay

@SGaist

I want to build all qt5 modules for apalis-tk1.So I cloned qt5. I use https://code.qt.io but I get the same error again.

Where is the problem? I can not find a solution.

Qwidget works fine. Qml and quick do not work.

SGaist

What do you mean by do not work, you can't build the modules or you can't run an application ?

aktay

@SGaist
I mean I can't build the modules. But I solved the problem.
I have set Qt mkspec as described on the link below.
http://developer.toradex.com/knowledge-base/how-to-set-up-qt-creator-to-cross-compile-for-embedded-linux#Add_Kit

Qt mkspec :

/home/abdullah/apalis-sdk/sysroots/armv7at2hf-neon-angstrom-linux-gnueabi/usr/lib/qt5/mkspecs/linux-oe-g++

In this case, there is a new error.. I am getting the following error in Qt Creator.

Looks like your mkspec contains an error since you just have o rather linux-oe-g++.
