How to run QT application on X-window of the embedded platform

[uniquez]

Yesterday I tried to compile QT-LIB following what you said. However, when I compiling the qt-everywhere-opensource-src-4.8.1, there is a error :

/home/xushaofan/qt_4.8.1_pkg/qt-x11-opensource-src-4.8.1/bin/qmake: 1: Syntax error: word unexpected (expecting ")")

My configure is "./confugure -platform arm-none-linux-gnueabi-g++" as you told me , and I think I configure environment variables correctly.
Can you tell me where someting wrong is? Thank you very much.

You should use qmake for target platform (that runs on x86, but produces output for arm), not native qmake.

[uniquez]

Sorry to reply later beacause I was busy for other things these days.

[quote author="Serg" date="1337231425"]You should use qmake for target platform (that runs on x86, but produces output for arm), not native qmake.[/quote]

I think "qmake" is a tool used for generating Makefile, so it runs on x86, and produces output(Makefile) for X86 not for arm. Is that true?

By the way, I find an other way to get qt-lib for X11 based arm. I link the system with internet, and use “apt-get instal libqt4-dev”, then the ubuntu can download qt-lib for arm. However, when I run a QT test-program(compiled linking downloaded QT-lib) on my system, the program can output a window, but have an error:"undefined symbol: _ZN7QWidget8qwsEventEP8QWSEvent". Can you tell me what wrong about this way to get QT-lib and run QT-program.

Thanks for your warm-heart again!!!

[Serg]

bq. I think “qmake” is a tool used for generating Makefile, so it runs on x86, and produces output(Makefile) for X86 not for arm. Is that true?

The qmake tool requires a platform and compiler specific qmake.conf file describing the various default values, to generate the appropriate Makefiles. You should use correct qmake.conf file.

bq. However, when I run a QT test-program(compiled linking downloaded QT-lib) on my system, the program can output a window, but have an error:“undefined symbol: _ZN7QWidget8qwsEventEP8QWSEvent”. Can you tell me what wrong about this way to get QT-lib and run QT-program.

Looks like your program uses QWidget::qwsEvent(), that is not available in non-embedded linux environments. "Check this thread":http://qt-project.org/forums/viewthread/3043 .

[uniquez]

The second question.
My test program can run on Ubuntu on my PC, which is non-embendded linux environment too. And I am sure my test program (just a MainWindow) not using QWidget::qwsEvent()。

[uniquez]

The first question.
When I use "./configure -xplatform linux-arm-gnueabi-g++ "to configure, there is no error about "/home/xushaofan/qt_4.8.1_pkg/qt-x11-opensource-src-4.8.1/bin/qmake: 1: Syntax error: word unexpected (expecting “)”)", but it generate an error:

"Basic XLib functionality test failed!
You might need to modify the include and library search paths by editing
QMAKE_INCDIR_X11 and QMAKE_LIBDIR_X11 in /home/xushaofan/qt_4.8.1_pkg/qt-everywhere-opensource-src-4.8.1/mkspecs/linux-arm-gnueabi-g++."

I find the variables of QMAKE_INCDIR_X11 and QMAKE_LIBDIR_X11 is in the /mkspecs/common/linux.conf, and I change the variables to XLib's path， but this error remain.

How to solve this problem?

[Serg]

qt-everywhere-opensource-src-x.y.z/mkspecs directory used for (cross) compiling Qt for various targets.
qt-everywhere-opensource-src-x.y.z/mkspecs/qws directory used for (cross) compiling Qt embedded for various targets.

So, I checked "mkspecs directory":http://qt.gitorious.org/qt/qt/trees/4.8/mkspecs and found a mistake.

bq. I’m not sure, but I think it will be correct: “./configure -platform arm-none-linux-gnueabi-g++”.

Correct is: "./configure -platform linux-arm-gnueabi-g++".

[uniquez]

Correct is: “./configure -platform linux-arm-gnueabi-g++”.

But in /mkspecs directory, there is no folder of "linux-arm-gnueabi-g++",and my qt opensource's version is 4.8.1. So I just copied /mkspecs/qws/linux-arm-gnueabi-g++ to /mkspecs. I think what I did is not true, but I dont know how to get linux-arm-gnueabi-g++ in /mkspecs.

[Serg]

About second question.
Your qt test program was built on arm system as a native program? Can you show ldd output?

bq. But in /mkspecs directory, there is no folder of “linux-arm-gnueabi-g++”,and my qt opensource’s version is 4.8.1. So I just copied /mkspecs/qws/linux-arm-gnueabi-g++ to /mkspecs. I think what I did is not true, but I dont know how to get linux-arm-gnueabi-g++ in /mkspecs.

Copy it from qt.gitorious, Are you checked the link "mkspecs directory":http://qt.gitorious.org/qt/qt/trees/4.8/mkspecs ?

[uniquez]

My cross compiler is arm-none-linux-gnueabi-g++ not linux-arm-gnueabi-g++.

I copy the folder of linux-arm-gnueabi-g++ from qt.gitorious to /mkspecs, and I replace "linux-arm-gnueabi-g++" for "arm-none-linux-gnueabi-g++ ". Then I configure "./configure -platform linux-arm-gnueabi-g++",there is two errors:

Basic XLib functionality test failed!
You might need to modify the include and library search paths by editing
QMAKE_INCDIR_X11 and QMAKE_LIBDIR_X11 in /home/xushaofan/qt_4.8.1_pkg/qt-everywhere-opensource-src-4.8.1/mkspecs/linux-arm-gnueabi-g++.

But if I configure "./configure -xplatform linux-arm-gnueabi-g++" after clean configure, there just an error:

Basic XLib functionality test failed!
You might need to modify the include and library search paths by editing
QMAKE_INCDIR_X11 and QMAKE_LIBDIR_X11 in /home/xushaofan/qt_4.8.1_pkg/qt-everywhere-opensource-src-4.8.1/mkspecs/linux-arm-gnueabi-g++.

[Serg]

So, there are two ways:

1. Write your own mkspec for arm-none-linux-gnueabi-g++ compiler (or find in google). Then ./configure -arch arm -xplatform arm-none-linux-gnueabi-g++;
2. "sudo apt-get install g++-arm-linux-gnueabi" and try to use mkspec from qt.gitorius. Then ./configure -arch arm -xplatform linux-arm-gnueabi-g++.

bq. Basic XLib functionality test failed! You might need to modify the include and library search paths by editing QMAKE_INCDIR_X11 and QMAKE_LIBDIR_X11

You need to specify X11 include files and libraries, arm libs!

[uniquez]

You need to specify X11 include files and libraries, arm libs!

================================

I have specified X11 include files and libraries(for arm)' path by modifing linux.conf in /mkspecs/common, but the error remain. Is it right?

It is too later tonight, I will compile QT-lib following what you said tomorrow.
Anyway, thank you help me again and again.

[uniquez]

By the way, the X11 include files and libraries are provided in filesytems by TI ezsdk.

[Serg]

bq. I have specified X11 include files and libraries(for arm)’ path by modifing linux.conf in /mkspecs/common, but the error remain. Is it right?

I'm think it's right.

This error can be when libXext is missed.
Here is "Qt for X11 requirements":http://qt-project.org/doc/qt-4.8/requirements-x11.html. Ensure that you have all required libs.

[uniquez]

One more question, when I configure my QT-lib compiling using "./configure -xplatform linux-arm-gnueabi-g++",
it outputs "You have not explicitly asked to use pkg-config and are cross-compiling.
pkg-config will not be used to automatically query cflag/lib parameters for
dependencies"
But when I use "./configure", there is no that message.

Although it is not en error, I think something is not configured right.

[Serg]

Try it: ./configure -arch arm -xplatform linux-arm-gnueabi-g++ -force-pkg-config

[uniquez]

After I modified "QMAKE_LIBS_X11 = -lXext -lX11 -lm -lxcb -lpthread-stubs -lXau -lXdmcp " in /mkspecs/common/linux.conf,
now I can configure successfully by using "./configure -arch arm -xplatform linux-arm-gnueabi-g++ -force-pkg-config".

However, after I "make", there are some errors:

Can you tell me how to eliminate these error?

When I make again by configuring " ./configure -arch arm -xplatform arm-none-linux-gnueabi-g++ -release -force-pkg-config"
There is an other error:

there are many more "undefined reference to" variables, why?

Are you sure that path to arm X11 libraries is correct (in linux.conf QMAKE_LIBDIR_X11 and QMAKE_INCDIR_X11) and X11 version is X11R6? If it's true, then i can suppose that arm-none-linux-gnueabi-g++ and linux-arm-gnueabi-g++ have a different binary format and ld can't link it. If i'm right, you should use one compiler for X11 libs and Qt. It means that you should use linux-arm-gnueabi-g++ rather than arm-none-linux-gnueabi-g++, because it's compiler from Ubuntu repository and you are compiling for Ubuntu.

But I didn't have any problems like this. So, I don't know what exactly you should do in this case :(
