[Linux-fbdev-users] Getting started

[William E. <mru...@po...>]

Hi guys,

  Would someone please point me to a 'Getting started' URL for framebuffer
support?

  I am running Fedora Core 4 and I have rebuilt the kernel to make sure
FB support is in the kernel.  I have a simple FB program that I have
compiled but everytime I try to run it, I get:

    Error: cannot open framebuffer device /dev/fb0. - No such device rc=-1

  The open code looks like this:

        // Open the file for reading and writing
        char*  FB   = "/dev/fb0";
        int    fbfd = 0;
        fbfd = open( FB, O_RDWR);
        if (fbfd < 0) {
          printf("Error: cannot open framebuffer device %s. - %s rc=%d\n",
                 FB, strerror(errno), fbfd);
            exit(1);
        }
        printf("The framebuffer device was opened successfully. - %d\n",
    fbfd );

  I have done the mkdir:

    [wre00@Shrek FB]$ ls -lrt /dev/fb*
    crwxrwxr-x  1 wre00 root 29, 0 Aug 17 10:05 /dev/fb0

  Any ideas/help??
