gf_dev_attach() failed with GF_ERR_IODISPLAY
I am trying to get Qt and QNX running on the Sabre Lite board. I have a Qt project (just a single button) and the
project builds and loads to the target using the Momentics debugger. However, the first line of code that executes:
QApplication a(argc, argv, global);
Causes this error:
QQnxScreen: gf_dev_attach() failed with error code 2
The error in the code says this:
#define GF_ERR_IODISPLAY 0x00000002 /* error accessing io-display */
My board does not have an io-display process, and there is no /dev/io-display directory. The QNX demo that is part of
the QNX accelerator kit quick start runs correctly and no io-display process is running.
How do I get past this error? Do I need an io-display process running?
Thanks,
Dave
