问题描述
我需要在同一台机器上构建一个iOS应用程序和一个Mac OS应用程序。 Mac OS应用程序需要在10.5上运行，即使Apple声称你可以使用10.6 SDK构建并通过设置正确的目标值在10.5上运行，但事实并非如此。简单的事情，比如 libssl 的名称/版本，在10.5和10.6上是不同的，这使得这不可能。
I need to build one iOS app and one Mac OS app on the same machine. Mac OS app needs to run on 10.5, and even though Apple claims you can build with the 10.6 SDK and run on 10.5 by setting the right target value, it's not true. Simple things, like the name/version of libssl, are different on 10.5 and 10.6 which makes this impossible.
无论如何，所以我即将尝试在XCode 4上安装XCode 3.2.6 - 我有XCode 4 - 任何提示/陷阱/指南？
Anyway, so I'm about to try and install XCode 3.2.6 on the same machine as I have XCode 4 on - any tips/gotchas/guides?
谢谢！
推荐答案
这应该可以正常工作，但最好最后安装XCode4。因此，如果您安装XCode3，您也需要在以后重新安装XCode4（以使系统工具保持最新版本）。
That should work fine, however it's best to install XCode4 last. So if you install XCode3 you'll want to re-install XCode4 as well after (to keep the system tools at the latest version).
我还建议使用XCode4进入/ Developer，XCode3进入一个带有其他名称的文件夹，因为它有更多的时间被安排在不同位置安装工作。
I'd also recommend XCode4 go into /Developer, and XCode3 goes into a folder with some other name, as it's had more time to be hammered out to work installed in different locations.
