<H2> 2.5 Platform Specific Problems </H2>
<!--docid::SEC117::-->
<P>
These problems are relevant for both compiling and running. Crystal Space is
work in progress. Expect these problems to go away in the future.
</P><P>
<UL>
<LI>
With the exception of MacOS/X Server, OpenStep, and NextStep, all ports of
Crystal Space require an 8-bit, 15-bit, 16-bit, or 32-bit display to run. It
will <EM>not</EM> work on 24-bit displays.
<P>
<LI>
DJGPP: If you have GCC 2.8.1 then you must disable optimization (use
<CODE>make djgpp MODE=debug</CODE>) before compilation because there seems
to be a bug in the optimizer. You can also download EGCS from
<A HREF="http://goof.com/pcg">http://goof.com/pcg</A> which fixes this problem and also generates a more
efficient executable.
<P>
<LI>
DJGPP: With very old versions of gcc you need to disable the assembler
routines (set <CODE>DO_ASM=no</CODE> in `<TT>mk/user.mak</TT>') because the assembler
doesn't understand some of the MMX routines. You should upgrade to a
more recent version of DJGPP if possible.
<P>
<LI>
OpenGL: If your OpenGL display looks really bad (bad quality of lighting
compared to the software renderer) then you have a card which doesn't support
the desired blending mode <CODE>2*SRC*DST</CODE> that Crystal Space uses. You can
edit `<TT>data/config/opengl.cfg</TT>' and change the `<SAMP>LightmapMode</SAMP>' option to
`<SAMP>multiply</SAMP>' (which all cards should understand) or any of the other
values. `<SAMP>multiply</SAMP>' will make everything dark but at least it will look
right. The RIVA 128ZX is an example of a card which doesn't support
<CODE>2*SRC*DST</CODE>.
<P>
<LI>
Direct3D: The Direct3D port suffers from the same bug as the OpenGL port with
the lightmaps not correctly applied on some 3D cards.
