Hi there,
not sure what is going on but it looks like only 8 bit or 16 bit depths
(bits per pixel) are supported,
meaning for instance UT8 or RGB16. There are some values in the switch
witch are never hit even, as far as I can tell.
Strange to see both DFB_BITS_PER_PIXEL and DFB_BYTES_PER_PIXEL, since
the latter is just a rounded variant of the former.

Hey,
I wrote a few days ago to the links-mailing-list, but didn't get any
response so far.
However I would really like to see links2 running on top of directfb -
so I hope maybe somebody here might see what's the problem.
I'm trying to get links2 running on top of DirectFB.
DirectFB in general is working (gtk2-applications work), however running
links returns the following error:
# links -g -driver directfb
[..]
Could not initialize graphics driver directfb:
Unsupported color depth.
I added some printf's around the code-snippet in directfb.c which is
printing this error-message:
===
pixelformat = config.pixelformat;
directfb_driver.depth = (((DFB_BYTES_PER_PIXEL (pixelformat) & 0x7)) |
((DFB_BITS_PER_PIXEL (pixelformat) & 0x1F)
<< 3));
printf("pixmap: %x\n", pixelformat);
/* endian test */
if (htons (0x1234) == 0x1234) {
printf("endian test: true\n");
} else {
directfb_driver.depth |= 0x100;
printf("endian test: false\n");
}
printf("color depth: %i\n", directfb_driver.depth);
switch (directfb_driver.depth) {
case 33:
case 65:
case 122:
case 130:
case 378:
case 386:
case 451:
case 195:
case 452:
case 196:
case 708:
break;
default:
layer->Release(layer);
dfb->Release(dfb);
return stracpy("Unsupported color depth.\n");
}
===
The output is now the following:
# links -g -driver directfb
[..]
pixmap: 400c03
endian test: false
color depth: 260
Could not initialize graphics driver directfb:
Unsupported color depth.
versions:
links: 2.1pre37
libdirectfb: 1.4.2
directfb_driver.depth has a value which is not within the
switch-statement - but why not?
What's "color depth" exactly? Is it fixed? Is it hardware specific?
And the general question - how to get working? :)
Thanks a lot in advance!
