Building on MacOS X

I've been trying to build Rocks'n'Diamonds on MacOS X (intel).
Well, I actually built it with "make mac" and having installed the SDL libraries required with darwinports.
The problem is: the program is horribly slow. If there's much graphical action (such as displaying the graphics/sounds loaded at startup or magic walls) I can watch every block on the field being updated seperately.
The strange thing is: If I use the pre-built (PowerPc) binary from artsoft.org it's much faster (though still slower than it should be).
In full-screen mode everything runs fine.
So: How do I build a fast version for MacOS X?

Have you tried to link the SDL libraries static with the executable?

Yes, but "make mac-static" gives me:
Code: Select all
/usr/bin/ld: Undefined symbols:
__Unwind_Resume
I haven't figured out yet where this symbol should come from, so I couldn't test the result yet.
On the other hand I cannot believe that dynamic linking can cause such a big problem

Yes, thats true- But on windows the feeling with static libs is a little bit faster (my opinion).
May be on your Intel-Mac you have to rebuild the SDL-Lib's.
May some 'make' files or some 'defines' dont regognize that there is a Intel-Mac.

Strange. I wouldn't have expected this on an intel Mac...

Even stranger, as it has to be emulated... :-o

That's something I have observed on my iBook, too: Incredibly slow on the desktop (windowed mode), acceptably fast in fullscreen mode. But then, this iBook has only 500 MHz and non-accelerated graphics...

Unfortunately, I have no idea.
I suspect this having something to do with the SDL libraries -- have you natively build them? But even then it might be possible that they simply need some special treatment to run well on intel Macs. (As the pre-build binary works better, I indeed think that it has something to do with the SDL libraries -- but still it's strange...)

This should not make a big difference...
