安装 Xcode 4.3 后无法获得 MacPort 功能

Unable to get MacPort functionality after installing Xcode 4.3

提问by Jason

I am having trouble getting MacPorts to function properly. I just installed OSX Lion 10.7.3 I downloaded and installed MacPorts first, and then after reading the requirements, I downloaded Xcode4.3 from the App Store, and then installed it. I launched Xcode and it looks to be operational and functional. However when I attempted to port with MacPorts, it gave me this error message(excerpt):

我无法让 MacPorts 正常运行。我刚安装了OSX Lion 10.7.3 我先下载安装了MacPorts，然后看了需求，从App Store下载了Xcode4.3，然后安装了。我启动了 Xcode，它看起来可操作且功能正常。但是，当我尝试使用 MacPorts 进行移植时，它给了我以下错误消息（摘录）：

Warning: xcodebuild exists but failed to execute
Warning: Xcode does not appear to be installed; most ports will likely fail to build.

I followed the advice from:

我遵循了以下建议：

How do i install additional packages for Xcode on OSX Lion to allow MacPorts to work

我如何在 OSX Lion 上为 Xcode 安装额外的软件包以允许 MacPorts 工作

and installed command_line_tools_for_xcode from the Preferences within Xcode. I closed Xcode, and again got the errors:

并从 Xcode 中的首选项安装 command_line_tools_for_xcode。我关闭了 Xcode，再次出现错误：

$ sudo port install libsocketsPassword:

I am uncertain where to go next with this. How do i trouble shoot my Xcode and MacPort interface?

我不确定下一步该去哪里。如何解决我的 Xcode 和 MacPort 接口问题？

In theory this should work if you have Xcode4.3 installed (in /Applications):

理论上，如果您安装了 Xcode4.3（在 /Applications 中），这应该可以工作：

$ sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer/

(And you've installed the optional command line tools)

（并且您已经安装了可选的命令行工具）

Everything will start working fine after installation of "Command Line Tools for Xcode" package. You can get it from here: https://developer.apple.com/downloads/index.action#

安装“Xcode 命令行工具”包后，一切都会开始正常工作。你可以从这里得到它：https: //developer.apple.com/downloads/index.action#

Please see the MacPorts migration instructions for Xcode 4.3.

请参阅Xcode 4.3的MacPorts 迁移说明。

The instructions are pretty involved. You need to run xcode-selectto set a new tools path, update developer_dirin macports.conf(as described by Henk Poley), re-install MacPorts (ouch), and finally uninstall and re-install all of your ports (double ouch).

说明相当复杂。您需要运行xcode-select设置一个新的工具路径，更新developer_dir中macports.conf（如由亨克Poley），重新安装的MacPorts（哎哟），最后卸载和重新安装所有的端口（双哎哟）。

Edit:libpvxstill wouldn't install after the above. Two extra steps were required:

编辑：libpvx在上述之后仍然不会安装。需要两个额外的步骤：

1. sudo ln -s /Developer /
2. sudo ln -s /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs /SDKs

1. sudo ln -s /Developer /
2. sudo ln -s /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs /SDKs

YMMV if you have different ports installed!

YMMV 如果您安装了不同的端口！

Also in /opt/local/etc/macports/macports.confchange the line with developer_dirto point to /instead of /Developer.

同样在/opt/local/etc/macports/macports.conf更改行developer_dir中指向/而不是/Developer。

After

后

sudo xcode-select -switch /Applications/Xcode.app

I also had to run

我也不得不跑

sudo xcodebuild -license

and accept the licence

并接受许可

Here is a solution that has worked for me:

这是一个对我有用的解决方案：

1. Install Command Line Tools for Xcode

   Xcode -> Preferences -> Downloads
   

2. Help MacPorts find the right Xcode folder

   sudo /usr/bin/xcode-select -switch /Applications/Xcode.app
   

3. Create symbolic links for clang compilers as they now live elsewhere

   sudo ln -s `which clang` /Applications/Xcode.app/Contents/Developer/usr/bin/
   sudo ln -s `which clang++` /Applications/Xcode.app/Contents/Developer/usr/bin/
   

1. 为 Xcode 安装命令行工具

   Xcode -> Preferences -> Downloads
   

2. 帮助 MacPorts 找到正确的 Xcode 文件夹

   sudo /usr/bin/xcode-select -switch /Applications/Xcode.app
   

3. 为 clang 编译器创建符号链接，因为它们现在位于其他地方

   sudo ln -s `which clang` /Applications/Xcode.app/Contents/Developer/usr/bin/
   sudo ln -s `which clang++` /Applications/Xcode.app/Contents/Developer/usr/bin/

None of this works for me. Wait for macports to release a new version that officially supports XCode 4.3+

这些都不适合我。等待macports发布正式支持XCode 4.3+的新版本

回答by Pall Melsted

Setting the developer path in /opt/local/etc/macports.conf works for me,

在 /opt/local/etc/macports.conf 中设置开发人员路径对我有用，

developer_dir /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain

since most of the compilers are stored there now instead of /usr/bin under Developer.

因为现在大多数编译器都存储在那里而不是 Developer 下的 /usr/bin 。

Try using trunk, there's no release supporting Xcode 4.3 yet.

尝试使用主干，尚无支持 Xcode 4.3 的版本。
