Hello,

I'm trying to get a text only version of POV-Ray 3.1g to work under Mac 
OS X because all of my textures, lighting etc have been setup for that 
version, changing them to a newer (3.5 or 3.6) version would take me 
too much time and I would like to leave Classic behind me. I've already 
installed XCode 1.1 and downloaded the 3.1g sources but then the 
absence of compiler knowledge hits me...

I did manage to change the CFLAGS line into:

# Mac OS X compiler flags, Altivec optimized
CFLAGS       = -faltivec -c -ansi $(SRCINC) $(LIBPNGINC) $(ZLIBINC)

Entering "make newunix" in the unix-subdirectory starts compiling 
things nicely now, but then I get the following status reported back to 
me:

gcc ./atmosph.o ./bbox.o ./bcyl.o ./bezier.o ./blob.o ./boxes.o

povray

ld: can't locate file for: -lpng
make[1]: *** [povray] Error 1
make: [newunix] Error 2 (ignored)


I assume that libpng needs to be compiled as does zlib, but I haven't 
been able to get them to work, could someone help me out on this...?
