我刚刚下载了Qt 5.0的源代码，并将其编译到Ubuntu 12.10 64位上。运行sudo make install似乎已经将文件复制到/usr/local/Qt-5.0.0：如何让Qt 5.0与Qt Creator 2.5.2一起工作？
到目前为止好。但是当我启动Qt Creator 2.5.2并尝试将其指向新版本时，出现一个不寻常的错误：The default mkspec symlink is broken。
什么可能导致这种错误的？ /usr/local/Qt-5.0.0/mkspecs下的所有符号链接都是有效的。的qmake -query输出如下：
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 QT_INSTALL_DOCS:/usr/local/Qt-5.0.0/doc QT_INSTALL_HEADERS:/usr/local/Qt-5.0.0/include QT_INSTALL_LIBS:/usr/local/Qt-5.0.0/lib QT_INSTALL_LIBEXECS:/usr/local/Qt-5.0.0/libexec QT_INSTALL_BINS:/usr/local/Qt-5.0.0/bin QT_INSTALL_TESTS:/usr/local/Qt-5.0.0/tests QT_INSTALL_PLUGINS:/usr/local/Qt-5.0.0/plugins QT_INSTALL_IMPORTS:/usr/local/Qt-5.0.0/imports QT_INSTALL_QML:/usr/local/Qt-5.0.0/qml QT_INSTALL_TRANSLATIONS:/usr/local/Qt-5.0.0/translations QT_INSTALL_CONFIGURATION:/etc/xdg QT_INSTALL_EXAMPLES:/usr/local/Qt-5.0.0/examples QT_INSTALL_DEMOS:/usr/local/Qt-5.0.0/examples QT_HOST_PREFIX:/usr/local/Qt-5.0.0 QT_HOST_DATA:/usr/local/Qt-5.0.0 QT_HOST_BINS:/usr/local/Qt-5.0.0/bin QMAKE_SPEC:linux-g++-64 QMAKE_XSPEC:linux-g++-64 QMAKE_VERSION:3.0 QT_VERSION:5.0.0
我还要指出的是，我没有安装这台机器上的Qt 4.x的开发文件：
