I see there is universal build of libpng 1.2.17 here, but I have not tested it. From the installer notes:

“Installs static (.a) and dynamic (.dylib) universal binaries of libpng, as provided by the official libpng reference release: http://www.libpng.org/pub/png/libpng.html

The libraries will be installed into /usr/local/lib, and the header files into /usr/local/include.”

I’m not sure if it’s much help in the long run without notes on how it was actually built, but maybe it’ll provide a few leads.

Thanks. I eventually figured out how to get it to build. The trick was to build the two versions separately (ppc and i386), and then use lipo to join them. Building for both architectures at once just gave an error that some of the gcc command line arguments weren’t compatible with having multiple -arch arguments (which seems really stupid).

So I built libpng 1.2.18, then rebuilt megapov in universal mode with a static libpng and replaced my original upload. I’d really appreciate it if someone with a PPC Mac would test it.

You can download a test POV file here:

Once again the MegaPOV 0.7 build is here:

http://www.halibut.com/~tcobbs/ldraw/private/megapov.bz2

Once you have both of those in a directory together, use the following command lines from that directory:

bunzip2 megapov.bz2
chmod 755 megapov
./megapov +im6459.pov
open m6450PP.png

That should show you the render.
