Virtual Frame Buffer usage
Message 1 in thread
Hello,
I am trying to use qt-2.3.10 with opie on EP9315 ARM processor.
Can I use QT4.3 designer, to develop my application, and port my code
back to QT2.3.10, is the code sort of back compatible with minor
changes?
I am really confused about the usage of virtual frame buffer, how do I
setup the environment to start developing application in virtual frame
buffer and later translate the same code to be used on EP9315?
1) I guess the first thing is to configure and compile qt 2.3.10 with
-qvfb option. (This works well).
2) download and link precompiled qvfb.
3) make menuconfig for opie and try to compile it for X11, with qpe, is
this required?. I cannot make this compile properly. All kinds of errors
4)Now if you successfully compile X11 with qpe, then I can say
qvfb&
qpe
this will allow you to connect to qvfb.
5) now after I build the application for x86 target (or ARM, does it
matter what target I build it towards), say
./myhello -qws
this will allow u to run the application in the virtual frame buffer.
Are these the basic steps involved in using virtual frame buffer?
Does anyone use virtual frame buffer at all for developing GUI for
EP93XX? Or do people just compile and try it out on the evaluation board
itself?
I would really appreciate if some one could answer some of these
question.
