qvfb

[augusbas]

hi augusbas

tanks for the replay.

I have checked out the major and minor numbers and created two frame buffers fb0 and fb1.
I have some misunderstanding also with the display setting. which value to give for who. like: QWS_DISPLAY =
DISPLAY =
were to mention the path "/dev/fb0"

regards,
henk

Don't worry about display setting now , it will use its default setting

Try to run any application for example..

./Analaogclock -qws in one terminal and try ./qvfb in another terminal ...See whether the application is running.

hm...
actually I am re configureing the Qt/X11 with ./configure -qvfb option.
..

./qvfb do nto work but just qvfb open the virtual framebuffer
and when I run ./analogclock_back -qws on other terminal
i get the following error
bash: ./analogclock_back: cannot execute binary file

but when I copy the whole sample file to another directory and run qmake to create a Makefile and run the make command it will re-create the binary file. This time it will run but not in the virtual framebuffer even-though I give -qws option.

I appreciate all help provided.
this is my second week on this..

You cant use an X11 Qt together with the framebuffer. You will however need a QVFB executable that you can build from the desktop Qt and then use a Qt embedded to connect to that framebuffer.

So you need both: Qt x11: Build it, use the qvfb executable from here. Qt embedded: Use this to build the application that shall use the frame buffer.
