[Buildroot] Compiling process

[Zoran Djordjevic]

Hello
?
Can someone tell me through an example?what compiler line 
should look like for compiling SomeFile.c (or .cpp) using compiler, 
built by Buildroot. 
Also, does Qt need building X server, or it run independently of it ?
Does some window manager have to be installed??
?
Best regards

Hi,

I am currently working with QT without X. It runs directly on the Linux
framebuffer.

No, but you have to start the app with the "-qws" option.

Kind regards

Can you tell me, Stephan, what is your developement environment?
Can I use some ordinary?editor to create .c or .cpp file and then 
compile from command line?
Do I have to write some code in Qt related source to react on -qws
option ?
?
Thanks

Hi,

I am currently working with QT without X. It runs directly on the
    Linux framebuffer.

Does some window manager have to be installed??  
No, but you have to start the app with the "-qws" option.

For now I only use the example and demo programs included in the QT
distribution (have to be enabled in buildroot xconfig).

For a user application I would create a package according to the
buildroot documentation. Of Course you have to write a QT application;-)

QT has the advantage to be cross-platform, so you should be able to
create and test the application on your desktop (e.g. with qt designer)
and compile it afterwards within buildroot.

You should also be able to build/use Qt-based X clients without
building an X server.  The same is true of any X client, regardless of
framework/widget-library.  You'll probably have to build Xlib, but you
shouldn't have to build an X server.  [I vaguely remember an X11
widget library that didn't use Xlib, but I think all the popular ones
do.]

Or with whatever option points the X-client Qt app at an X server on a
different host.

Use the compiler in output/host/usr/bin/<arch>-gcc.

> Also, does Qt need building X server, or it run independently of it ?

No, it can run directly on the framebuffer.

> Does some window manager have to be installed??

For a simple full screen application, just run your Qt application with
-qws as others mentioned.

If you want to build your Qt application with qmake, then use the qmake
installed in output/host/usr/bin/qmake.

I should probably put together a step-by-step tutorial on how to use
Buildroot to write Qt apps, as this sounds like a popular request.

Best regards,

Thomas

Hi,

I would really welcome such a paper since I am currently working on a QT
platform based on iMX5.

BTW: Does anybody have experiences with multitouch and QT?

Kind regards

Stephan
