IConfuguring QT for remote development on a Windows PC

K-Str

@Ronel_qtmaster Tthanks for your help.
But there are some differences to your QT version.
But step 6 is not really clear for me:

Create a new folder called qtraspberry
 Go to path_of_installed_qt\Qt5.13.2\5.13.2 and copy Src folder to qtraspberry

 Go to qtraspberry\Src and open the file \qtbase\mkspecs\linux-arm-gnueabi-
g++\qmake.conf in a textEditor

 Replace arm-linux-gnueabi- with arm-linux-gnueabihf- in the whole file
 Go to \qtbase\mkspecs\win32-g++\qmake.conf and add -U__STRICT_ANSI__ to
CXXFLAGS
 Results should be like this:

I can not find a Src folder in the QT folder and nor qmake.conf on the PC.
Where is this?

Ronel_qtmaster

@K-Str Good Morining.Sorry i did not notice that you was using Qt6.Anyway, the procedure is globally the same.
Well Src folder is just the folder containing sources of Qt.When you install qt, you can select sources so that the program downloads them as well.

K-Str

@Ronel_qtmaster Thanks for your answer! can I reinstall the Src? or must I install qt completely?

or must I install qt completely?

No, just download Qt source code for your platform (https://download.qt.io/archive/qt/6.6/6.6.3/single/) - for Windows you need the zip archive.

@K-Str RaspberryPI running with Linux means you need to download the tar.xz archive.

K-Str

@jsulm Thanks. I use Windows 10 as host.

@K-Str in step 7 you write:

Enter in the build folder.Then launch msys.bat. It is located in the folder
c:\SysGCC\MinGW32\msys\1.0\msys.bat

but I can nor t find a file like msys.bat there is also no directory mysys...
Please could you help me?

Ronel_qtmaster

@K-Str Hi.Did you install Mingw as specified in the guide?You may also verify if the version in the guide correspond to what you have downloaded.In fact, mysys helps you to run linux like command line environment in windows.

K-Str

@Ronel_qtmaster yes I did everything as requested. The only I havn't done I did not install python. Is this the reason?
Maybe there is something wrong. because the directoryname is diffrent:

Ronel_qtmaster

@Ronel_qtmaster did you take mingw with the gcc version of 4.8.1?

K-Str

@Ronel_qtmaster , no I used this one:
mingw32-gcc12.2.0.
Is it better to use 4.8.1?
How can I remove the wrong version?

Ronel_qtmaster

@K-Str yes use the exact version specified in the tutorial.Because it has mysys.That said, just uninstall the current version and download 4.8.1

Christian Ehrlicher

@Ronel_qtmaster And once again you are posting wrong stuff... Qt6 does not compile with a gcc older than gcc 8 or even 9...

Ronel_qtmaster

@Christian-Ehrlicher i know that.But the purpose is to make him understand cross compilation first(The process) Not absolutely which version is right or wrong.

Christian Ehrlicher

@Ronel_qtmaster And what helps when he is using an outdated and unsupported compiler? It's just nonsense.

K-Str

@Ronel_qtmaster this means it's better to use vesion Qt5.13.2?

Ronel_qtmaster

@K-Str yes.You can try with Qt 5.13.2 as refered to the tutorial.Just to understand cross compilation because it is a tricky task especially in windows.Then when you master it, you will be able to handle compilation with Qt6 I am sure.

Ronel_qtmaster

@Christian-Ehrlicher i am just trying to explain as much as possible.If you can add additional infos they will be welcomed

K-Str

@Ronel_qtmaster @Christian-Ehrlicher, thanks for your contributions
It is very helpful to me.
If there is no tutorial how to install qt6 I will try version 5.13.2 .
@Ronel_qtmaster is this Installation for python?
What must I do to install it for C++?
Ok! I tried to follow your instructions but there are some problems:
Step 5 :

Go to C:\SysGCC\raspberry\arm-linux-gnueabihf\sysroot\arm-linux-gnueabihf and copy
libEGL.so.1 and libGLESv2.so.2 to C:\SysGCC\raspberry\arm-linux-
gnueabihf\sysroot\opt\vc\lib and C:\SysGCC\raspberry\arm-linux-gnueabihf\sysroot

But there is no ibEGL.so.1 etc.

Step 7 :

Copy and run the build script :
../Src/configure -platform win32-g++ -device-option CROSS_COMPILE=arm-linux-gnueabihf- -
release -opengl es2 -device linux-rasp-pi3-g++ -sysroot C:/SysGCC/Raspberry/arm-linux-
gnueabihf/sysroot -opensource -confirm-license -I C:/SysGCC/raspberry/arm-linux-
gnueabihf/sysroot/opt/vc/include -L C:/SysGCC/raspberry/arm-linux-gnueabihf/sysroot/opt/vc/lib

It causes some errors :

kurt@DESKTOP-V3KDDUA /c/qtraspberry/build
