How to start in cross compile

JonexElectronic

Hello, I want to learn more about cross compile to compile my Qt c++ program on and embeded system (AML-S905X-CC). Where should I start? I found some tutorial to do it on a raspberry but I do not want to copy and do not understand what I am doing.
any advice, any suggestion on how to do it or where to start?
Thanks

Hi,

Usually, companies providing boards also have documentation about cross-compilation for their target.

Then from your side, it will depend on what you need to do for your device. You might want to check the Yocto project.

@SGaist Thanks for your response. The documentation for this board is non-existent...
Board Info:
Architecture: aarch64
arm-linux-gnueabihf
I have installed a raspbian SO
It is not a raspberry but it similar.

At the moment, I have done the next step, but I dont know how to continue.

Install Qt5 on my target board

sudo apt-get build-dep qt5-default

Sync my pc with my target

DIRbASE=/home/juan/raspi
DIRjOB=p_5.6
VERbASE=qtbase5.6
VERmULTIMEDIA=qtmultimedia5.6
cd $DIRbASE/$DIRjOB
mkdir sysroot sysroot/usr sysroot/opt
rsync -avz pi@192.168.0.160:/lib $DIRbASE/$DIRjOB/sysroot
rsync -avz pi@192.168.0.160:/usr/include $DIRbASE/$DIRjOB/sysroot/usr
rsync -avz pi@192.168.0.160:/usr/lib $DIRbASE/$DIRjOB/sysroot/usr
rsync -avz pi@192.168.0.160:/opt/vc $DIRbASE/$DIRjOB/sysroot/opt

Get th QT 5.6 Version ( I know I is old but i need it to my project)

git clone git://code.qt.io/qt/qtbase.git -b 5.6
git clone git://code.qt.io/qt/qtmultimedia.git -b 5.6

Try to configure QT on my PC

cd $DIRbASE/$DIRjOB
mkdir $DIRbASE/$DIRjOB/qt
cd $DIRbASE/$DIRjOB/qt
$DIRbASE/$VERbASE/configure -release -opengl es2 -device linux-arm-generic-g++ -device-option CROSS_COMPILE=$DIRbASE/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian/bin/arm-linux-gnueabihf- -sysroot $DIRbASE/$DIRjOB/sysroot -opensource -confirm-license -make libs -prefix /usr/local/qt5pi -extprefix $DIRbASE/$DIRjOB/qt5 -hostprefix $DIRbASE/$DIRjOB/qt5 -v -nomake examples -nomake tests -no-xinput2

I am not sure that the tool that I have is the correct one to my board. How could I know? Or what should I do to find?
With the one I have downloaded, I get some errors.

 You might need to modify the include and library search paths by editing
 QMAKE_INCDIR_OPENGL_ES2, QMAKE_LIBDIR_OPENGL_ES2 and QMAKE_LIBS_OPENGL_ES2 in
 /home/juan/raspi/qtbase5.6/mkspecs/devices/linux-arm-generic-g++.

SGaist

You need to install the development libraries of the dependencies in the sysroot. This is usually done using the device and then sync back to your desktop machine.

JonexElectronic

@SGaist I did

Sync my pc with my target
DIRbASE=/home/juan/raspi
DIRjOB=p_5.6
VERbASE=qtbase5.6
VERmULTIMEDIA=qtmultimedia5.6
cd $DIRbASE/$DIRjOB
mkdir sysroot sysroot/usr sysroot/opt
rsync -avz pi@192.168.0.160:/lib $DIRbASE/$DIRjOB/sysroot
rsync -avz pi@192.168.0.160:/usr/include $DIRbASE/$DIRjOB/sysroot/usr
rsync -avz pi@192.168.0.160:/usr/lib $DIRbASE/$DIRjOB/sysroot/usr
rsync -avz pi@192.168.0.160:/opt/vc $DIRbASE/$DIRjOB/sysroot/opt

I want to configure using my gcc-multilib (because I have already installed), because these toolchains are deprecated.
Is it the same to use "gcc-multilib" and "gcc-arm-linux-gnueabihf"?
If I use gcc-multilib, how could I define my target architecture? or will gcc configure my cross compilation for all the posibilities?
Where it is usually located the gcc-multilib?
Thanks

SGaist

I don't know how the compilers are configured with gcc-multilib. However I don't see anything wrong with trying with it.

Just a side note: you do realize that Qt 5.6 is more than outdated ?

JonexElectronic

@SGaist
I've taken a few more steps, but I got some errors when I do "make"
I have configured qt with this:

#!/bin/bash
~/rpi/qtbase/configure \
        -v \
        -release \
        -make libs \
        -opensource \
        -confirm-license \
        -opengl es2 \
        -platform linux-g++ \
        -device linux-rasp-pi2-g++ \
        -device-option CROSS_COMPILE=/usr/bin/arm-linux-gnueabihf- \
        -prefix /usr/local/qt5 \
        -extprefix ~/rpi/qt-build/qt5pi \
        -hostprefix ~/rpi/qt-build/qt5 \
        -sysroot ~/rpi/sysroot \
        -nomake examples \
        -nomake tests \
        -no-compile-examples \
        -no-xinput2 \
        -skip qtscript

NOTE: Qt is using double for qreal on this system. This is binary incompatible against Qt 5.1.
Configure with '-qreal float' to create a build that is binary compatible with 5.1.

Qt is now configured for building. Just run 'make'.
Once everything is built, you must run 'make install'.
Qt will be installed into /usr/local/qt5

Prior to reconfiguration, make sure you remove any leftovers from
the previous build.
