[Solved] Upgraded from Qt 5.2.1 to 5.3.1, LinuxFb is not working

[Sidii]

Hi all,
Today only i upgraded my QT (downloaded the source for 5.3.1 and cross compiled it) When i did it for QT 5.2 i used

@-qpa -LinuxFb@

while giving configure command.

But when i did the same for QT 5.3.1 i am getting error:

@
This application failed to start because it could not find or load the Qt platform plugin "linuxfb".

Available platform plugins are: linuxfb, minimal, offscreen.

Reinstalling the application may fix this problem.
Aborted (core dumped)
@

Kindly share your opinions.

Thanks

Hi,

Try again setting QT_DEBUG_PLUGINS=1 to see what happens with your plugin

Thanks SGaist.

When i did

@ldd libqlinuxfb.so@

Found that this has a dependency on

@ libQt5Network.so.5@

Aslo, so i placed libQt5Network.so.5 in the application folder and it worked.

Can you please tell me why linux Framebuffer has dependency on QT Network library? How a network connection is getting into picture? is it something related to VNC?

Thanks

[SGaist]

Right now, no I can't because it really doesn't make sense.

Not VNC related, AFAIK, this plugin has not been ported

Dear SGaist, thanks for the reply. I looked into the source code and then finally found that the Makefile for LinuxFb module was having LIBS and in that QT Network shared object was given. I removed that and now it is working fine without QT Network libraries.

Thanks :)

Cheers!
