[TUTO] Build Qt to cross compile for arm

[SGaist]

Again: this is an Qt for Embedded Linux build see the -embedded arm configure option. Thus my question, are you going to use the X Server of your Pi ?

If yes, you have to rebuild Qt without the embedded options but keep the ARM target.

If no, then one basic option is to copy the content of the cross-compiled Qt installation folder over to your Pi at the same place and you should be good to go (you can later remove stuff like the host tools headers etc.)

How can I do this compilation with opengl?

[SGaist]

Which version of Qt are you currently using ?

[HafsaElif]

Execute this command to install Qt in the /usr/local/Qt-4.8.5-arm/ directory : ./configure -opensource -confirm-license -prefix /usr/local/Qt-4.8.5-arm -embedded arm -little-endian -no-pch -xplatform qws/linux-arm-gnueabi-g++

In this step Did you create /usr/local/Qt-4.8.5-arm/ directory ? or Did created by qt creator when installitaion?

Hi,

I am not understood that fourth step,

Go to /home/<yourUserName>/
Execute this command to install Qt in the /usr/local/Qt-4.8.5-arm/ directory : ./configure -opensource -confirm-license -prefix /usr/local/Qt-4.8.5-arm -embedded arm -little-endian -no-pch -xplatform qws/linux-arm-gnueabi-g++
qt-everywhere-opensource-src-4.8.5/

why beacuse,when i go /home/<username> there is no such file called (this present in installQt directory) and in /usr/local also not present the Qt-4.8.5

anyone help how to processed next..
thankyou

@asha You should not copy the steps exactly, you have to adapt them to your environment:
Go to /home/<yourUserName>/ - this means go to your home directory
Qt-4.8.5 - change that to the Qt version you want to compile.

Sir,

I have uninstalled everything(which means cross compiler and my first qt version)

now i followed the steps,as said in above..

so now I am not getting where to execute.

can I execute where i am getting the configure file.

@asha said in [TUTO] Build Qt to cross compile for arm:

so now I am not getting where to execute

execute what? configure?
"can I execute where i am getting the configure file" - configure file is part of Qt source code. So, download Qt source code, extract it to a directory, go to that directory and execute configure there...

[Asha]

Hi,
I execute the configure file,as you can see here

After this Executed the make,the result is:

so what that error says?how to solve this..

[Asha]

Hi,

Any suggestions,

[jsulm]

@asha Please show how you call configure.
Also, it is better to post text instead of screen-shots...

[Asha]

I called configure
.

@jsulm sorry,ffor some of the reason using screenshots.

Hi,

Can anyone say,

what it does: fourth step

."/configure -opensource -confirm-license -prefix /usr/local/Qt-4.8.5-arm -embedded arm -little-endian -no-pch -xplatform qws/linux-arm-gnueabi-g++"

specially this part "embedded arm -little-endian -no-pch -xplatform qws/linux-arm-gnueabi-g++"

because,

I downloaded qt src code 5.7.1 and arm-linux-gnueabihf-gcc 6.5.0, and I found my qmake.conf file in "/home/<username>/Downloads/qt-everywhere-opensource-src-5.7.1/qtbase/mkspecs/linux-arm-gnueabi-g++"

So,now I need to configure,not getting the above path,I don't have qws directory,

can I give just ./configure for configuration?

@Asha
Same problem.

[IknowQT]

ERROR: Unknown command line option '-embedded'.
I'm getting an error, can you take a look?

[Pablo J. Rogina]

@IknowQT said in [TUTO] Build Qt to cross compile for arm:

ERROR: Unknown command line option '-embedded'.

You were already told to remove such option in this post.

Please don't double post, just follow one thread with your issue.

Getting Error : The errors we are encountering seem to be related to missing member variables and functions in the Ui::QPrintWidget and Ui::QPageSetupWidget classes, which are generated by Qt's User Interface Compiler (uic) based on .ui files. How to solve it ?
