Re: [pygame] help: how to make a mac osx installer?

["Brian Fisher" <brian@xxxxxxxxxxxxxxxxxxx>]

sweet! It works... I just ran a couple of my projects and they worked great... in particular they used png loading and created an openGL window. I think it would b great to get more people testing with that build

re: the i386 vs. PPC thing, I think "otool -f" will tell you what architectures the file includes. also, any otool command can also be run with "-arch ppc" or "-arch all" or whatever to check for stuff for a particular architecture.

looking at imageext.so, it seems to have ppc and i386 both in it. And I would think that the ppc image in the file wouldn't have linked if it hadn't been able to find symbols for the png and jpg calls for ppc, so It seems to me that things are universal binary ready...

thanks.

ah, apparently -static doesn't work on osx unless all of them are static.

This option will not work on Mac OS X unless all libraries (includ-

          option is not useful to most people.

I had to remove the /usr/local/lib/libpng*.dylib so that the .a one
was used statically.

Brian, can you please try this (UNTESTED!!!) file?  It should have
libpng, and libjpeg statically linked in.

I also noticed that the libpng, and libjpeg I have compiled are for
i386 only, and not ppc.  I'll have to recompile libpng, and libjpeg to
be both i386 and ppc.

Do you know of a way to check if something is ppc compatible as well
as i386 compatible?  I noticed because of the warning gcc gave.  It'd
be nice to add that check to the setup file to make sure everything is
ppc+i386 compatible.

I have some friends with ppc macbooks that I can ask them to test once
it's all working.


... getting there :)

cheers,
