Compiling Mac universal binary with 2.54

[username]

Hello,

Downloaded the latest install and ran cmake which generated an xcode project. I have two questions (I'm on a powerbook 64).

1. I compiled and ran the examples. Some examples run really slow and others run at the same speed as the precompiled binaries. Why would some demos such as ccdPhysicsDemo run so slow?

2. I want the library to be universal and compile for both intel and ppc. I'm just getting back into C++ development and so I'm really rusty but I'm getting the following errors during linking.

/usr/bin/ld: warning fat file: /usr/lib/libSystem.B.dylib does not contain an architecture that matches the specified -arch flag: i386 (file ignored)
/usr/bin/ld: Undefined symbols:
___keymgr_dwarf2_register_sections

It goes on and on with more but I think this gets the jist of it.

Thanks

It should just work with XCode and cmake. which versions do you have? Perhaps better to check the CMake mailinglist for help.

I just made Mac OS X universal demos, can you check if they work on PPC?

Erwin,

Sorry for the late response. I downloaded your file and was unable to run the apps. I get "cannot execute binary file" when I run from the terminal.

I'll check this post more often so I can help.

Thanks,
Joe

That is odd.

Which versions of Mac OS X, which version of XCode, and which version of gcc do you use?

Thanks,
Erwin

For Mac OS X I have 10.4.10
XCode is 2.4.1
And it looks like gcc 4.0
