I expanded Victor's makefiles which came with one version of 0.87 in the
contrib/djgpp directory dated 24th of May 2000. The makefiles that come with
versions 0.88 and above I could not get to run.
In version 0.92 the malpha demo did work, just the window title text was
gone. The other samples which I qualified as not working just showed a black
screen.
With 0.91 I did get 16bpp truecolor to work. So old drivers also supported
truecolor! However, 24bpp and 32bpp truecolor did display the wrong colors.
I do not know if this is caused by the grx20 library or Nano-X. Also the
palette colors are not set properly, I have to look into that.
>You need to implement a direct memory mapping, or a blit driver entry point
I tried to write a new screen driver for DOS but that did not work yet. How
do I implement a blit driver entry point? I would really like to do that. If
I look at the screendevice structure, there is no entry point for a blit
driver. E.g.:
SCREENDEVICE scrdev = {
0, 0, 0, 0, 0, 0, 0, NULL, 0, NULL, 0, 0, 0, 0, 0, 0,
gen_fonts,
X11_open,
X11_close,
X11_setpalette,
X11_getscreeninfo,
gen_allocatememgc,
gen_mapmemgc,
gen_freememgc,
gen_setportrait,
X11_update,
X11_preselect,
};
