Newer versions of MacOS pretty regularly break gcc.  Maybe check google and see if theres a fix. 

sudoman:
thanks for the advice. :) i updated to the latest deveolper tools for my system (3.1.4), but i'm still having the same problem.

i looked at what the manual install looks like and i noticed that the gcc patch is for version 3.4.6. the default compiler for my computer is gcc 4.0.1. gcc 4.2.1 is also available. would this be the cause of the problem? how can i work around this?  ???

i guess the solution might be to install a different version of gcc. which version should i install? and if it's 4.0+, do i need the os x patch for gcc-3.4.6?

3.4.6 is for coldfire, on arm we use 4.0.3.

You need to use 4.0.3.  The problem is probably that Apple broke something.  Figure out what it is or just use linux.

thanks for the help. that's my next operating system once i get a new non-ppc computer.  ;)

i should note that the wiki suggests not to use 4.0.x (for coldfire) but doesn't mention which compiler to use in making the cross-compiler.

http://www.rockbox.org/wiki/CrossCompiler

i'll let you know if that works.
