如何让Qt 5.0与Qt Creator 2.5.2一起使用？

Question

我刚刚下载了Qt 5.0的源代码,并在Ubuntu 12.10 64位上编译.运行sudo make install似乎已将文件复制到/usr/local/Qt-5.0.0:

到现在为止还挺好.但是当我启动Qt Creator 2.5.2并尝试将其指向新版本时,我得到一个不寻常的错误:The default mkspec symlink is broken.

什么可能导致这种错误？下面的所有符号链接/usr/local/Qt-5.0.0/mkspecs都是有效的.输出qmake -query如下:

QT_SYSROOT:
QT_INSTALL_PREFIX:/usr/local/Qt-5.0.0
QT_INSTALL_ARCHDATA:/usr/local/Qt-5.0.0
QT_INSTALL_DATA:/usr/local/Qt-5.0.0

我还应该指出,我没有在这台机器上安装Qt 4.x开发文件:

你不能让Qt 5在版本2.6.1之前使用Qt Creator.补丁级别很重要,版本2.6.0 不适用于最终版本.

Qt 5与Qt 4完全不同,它的新模块,库名称和qmake需要在整个地方进行相当多的更改才能获得支持.
