hi. when i try to run tools/rockboxdev.sh on os x 10.5.8, i get the following errors:

if more information is needed, just let me know.

please help!! thanks.

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.

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.

The 3rd line of the "manual build" section is quite clear what version to use, and provides you links to make sure you use them:

"ARM (arm-elf)    2.16.1 (download, mirrors, info)    4.0.3 (download, mirrors, info)"

Not to mention the rather obvious file names "rockbox-multilibs-arm-elf-gcc-4.0.3.diff".

This is for the compiler to build (i.e. the version of gcc for cross compiling), not the version of gcc to build the cross compiler.

could this be the answer:?

I was able to successfully build the cross compiler under OS X 10.5 on an Intel platform, and it's still working even after an upgrade to 10.6. I wasn't, however, successful in getting the cross compiler to build in OS X 10.5.8 on a PowerPC platform. The errors I got are the same as sudoman's original post. My machine is a PowerPC 970fx (G5).

[sudoman]

yeah, i'm on a PPC G4.

Edit: I tried installing a binary copy of gcc 4.2.1 using fink. even trying to compile the cross-compiler with this version of gcc failed.

I've managed to submit a patch without having to test it so i don't really need the cross-compiler anymore. no need to sweat it. thanks.
