Sorry I'm fairly new to configure files, as a developer. Additionally, will a 32-bit x86 library run on a 64-bit Mac, you might want to (if you want the enhanced performance from extra registers, or if people might want to link a 64bit application against your library) I just want to be sure that this won't fail on a PPC based system, when doing a build.

Configure and multiple OS X archs

site_archiver(a)lists.apple.com Delivered-To: darwin-dev(a)lists.apple.com Hi, I am trying to modify a configure script so that it supports generating of a universal binary (PPC & ix86). What I want to do is ensure that a universal binary is created, when the necessary SDK is available and the user had not explicitly stated they don't want a universal binary. Does this look right: Additionally, will a 32-bit x86 library run on a 64-bit Mac, or should I be adding support for x86_64? If the latter, what SDK dependencies are required?

site_archiver(a)lists.apple.com Delivered-To: darwin-dev(a)lists.apple.com -- Terry Hi, is it possible to trace C++ function? I was able to create prob for c++ function ::foo_cpp that was called from c function foo_c I created 2 probs one for foo_c and another for ::foo_cpp but I was able to see events only for foo_c prob (and I can see ::foo_cpp in stack) and none for ::foo_cpp prob I think it's wrong, because foo_c is called ONLY from ::foo_cpp Dmitry Markman _______________________________________________ Do not post admin requests to the list.

You can also add a string compare as one of the constraints on pthe probe firing (in the /<predicate>/).

It basically tells you how you have to define Objective C wrappers for the Objective C code you want to call from C so that it can be lined with the C to provide C wrappers.

Probably nothing. It's most likely a bug in the assembler or linker. Best submit a bug report to Apple with a compilable (subset of your) project. If you want feedback before that, you're most likely to get it on xcode-users as most Apple developer tools people are on that list. This email sent to site_archiver(a)lists.apple.com
