[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

[Buildroot] Compiling process

[Zoran Djordjevic]

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,

    Linux framebuffer.

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.

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,

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
