The larger question is probably "why are you asking about SMP support on Darwin x86". If you are expecting high or even reasonable performance (compared to Linux or FreeBSD), you're probably not installing Darwin for the right reasons. Darwin x86 is not about performance or peripheral support. So OS X is just going to be a snail on x86 or Darwin x86 will start to be about performance (peripheral support is another story)?

Here is my code: Could someone tell me why I cannot link to /usr/lib/libssl.dylib (itself a symlink to libssl.0.9.7.dylib)? You're linking to it fine. The problem is that you're linking to the wrong library. This may be covered in the OpenSSL documentation.

Our CFM executable application is considerably larger than that; some 35Mb. Our debug version of that is well into the 50Mb range. That is a CodeWarrior 8.3 limitation! Mach-O probably has a 2GB or even 4GB limit for your code :-) Therefore you can safely upgrade to Xcode 2.1. This email sent to site_archiver(a)lists.apple.com
