借助Qt支持，我现在已经解决了此问题.

With the help of Qt support, I've now resolved this.

有两个问题:

• Qt调试"make install"当前未为_debug东西生成dSYM文件.他们对此提出了一个错误.为了解决这个问题:

• The Qt debug "make install" doesn't currently generate dSYM files for the _debug stuff. They've raised a bug about this. To get round this:

4a. cd /usr/local/Trolltech/Qt-4.5.2/lib
4b.键入/usr/bin/dsymutil -o QtGui.framework/QtGui_debug.dSYM QtGui.framework/Versions/4/QtGui_debug
4c.对每个Qt框架重复以上操作.

4a. cd /usr/local/Trolltech/Qt-4.5.2/lib
4b. Type /usr/bin/dsymutil -o QtGui.framework/QtGui_debug.dSYM QtGui.framework/Versions/4/QtGui_debug
4c. Repeat for each Qt framework.

每次重新启动时，确实会擦除tmp目录.为了解决这个问题:

The tmp directory does indeed get wiped on each reboot. To get round this:

7-将/tmp/qt-mac-opensource-src-4.5.2的全部内容复制到新目录~/Qt.

7- Copy the entire contents of /tmp/qt-mac-opensource-src-4.5.2 to a new directory ~/Qt .

我还将框架和源代码都添加到了Xcode项目中.

I also added both the frameworks and source code to the Xcode project.
