osx-leopard

问题 I'm sure there must be a way to do this. As you are probably aware the latest versions of Xcode (and in fact I think all versions of Xcode) on Leopard come with GCC 4.0.1 and GCC 4.2. GCC 4.0.1 is the default system compiler while GCC 4.2 is an optional compiler you can set in the Xcode project settings. Does anyone know how to set GCC 4.2 as the default compiler for all options? Preferably command line use as well as configure scripts still use GCC 4.0.1 rather than GCC 4.2 no matter what I

问题 Since Apple only ships SDK 10.6 with Xcode4, developing PPC applications with Xcode4 became impossible. While it is possible to develop applications with Xcode4 that can also run on 10.5 and maybe even on 10.4 systems (by selecting SDK 10.6, but deployment target 10.5 or 10.4), they will only run on Intel Macs because you need at least SDK 10.5 for building PPC applications. Further there are some rare cases, where you really need to build against an SDK prior to 10.6 for full platform

问题 I accidentally removed /Library/Python on OS X Leopard. How can I reinstall that? 回答1: /Library/Python contains your python site-packages, which is the local software you've installed using commands like python setup.py install . The pieces here are third-party packages, not items installed by Apple - your actual Python installation is still safe in /System/Library/etc... In other words, the default OS leaves these directories mostly blank... nothing in there is critical (just a readme and a

问题 I'm trying to use PIL for a Google App Engine project. I've installed PIL using the installer from pythononmac.org but it doesn't seem to do anything, or at least neither I nor Python can find the files. I'm running Python 2.5.1. 回答1: The installers found on that page were designed to be used with the python 2.5 installer found there. Note that most of the packages are now out-of-date. The PIL installer uses the site-packages library in the framework used by the 2.5 Python on that page and by

问题 For Windows there is Win32 API, what about for Mac? On Wikipedia http://en.wikipedia.org/wiki/Cocoa_(API) it is said that Cocoa is "one of" the API... what about the full story? 回答1: At what level? The low level API is largely but not entirely FreeBSD, and below that there is still a Mach API (some things still use Mach ports for IPC, I believe; at least, launchd supports them). At the upper level are two APIs: Cocoa and Carbon. Cocoa is the native API; Carbon is intended for programs ported

问题 I had been using 2010 Macbook Pro for a while and had updated the Mac OSX to the latest version, and I had been suffering the slow speed for a long time. So last night I googled and do some cleanup , such as fix disk permissions, but the Mac was still slow. And someone suggest to re-install MacOSX. I was thinking it was the new version of Mac OSX's problem, I had the same kind of problems happen on the 1st version IPad either. After I reinstalled, the computer became much more faster. But I

问题 My applescript needs to detect its own filename, and the following runs fine on Snow Leopard (10.6) set my_name to name of me as string display dialog "Name: " & my_name It displays "Name: AppleScript Editor" when I run it from AppleScript Editor, and it displays "Name: NewTest" when I save it as an application called NewTest.
