Qt with Gfx Plugin

[nvharisha]

Hi,

I am bit new to Qt.
I am trying to cross compile Qt on my MIPS based platform. But the issue is, the platform has its own convention of using Graphics.
Hence instead of using LinuxFB or DirectFB, I have made my own.
But every time I try to run the application it gives : Driver not found
(during configuration i have added -plugin-xxx)

When I go inside I find .so for the plugin created. Even I have added that in LD_LIBRARY_PATH.

I have few questions:

1. When it says driver not found, is it looking in specific directory?
2. I assume that gfx driver means the plugin which I have created ("libgfx.so")
3. Is there any environment variable that need to be set. Currently I have only set QWS_DISPLAY=gfx

I am not sure where I am going wrong.

If these have been discussed, please point me to the link.

As a first step, I recommend setting the QT_DEBUG_PLUGINS environment variable to 1.

As a second step, you can try building and running the application located in qt/util/plugintest.

Those should help in tracking down the problem. You might also want to take a look at:

Hi Thanks for the reply.

Now i copied the plugin inside the application.
Even though file is present, it says it couldn't find.

I have added LinuxFb plugin, which it clearly finds out the "keys".
While I debug and find the reason, If you have any suggestions please let me know.
