我正在尝试在 Centos 6 上从源代码安装 QT Creator。我已经使用 yum 将 Qt5 库安装（我认为是）到我的系统上。当我检查安装了哪些 rpm 时，我看到了
[qt-creator-2.8.1-src]# rpm -qa | grep qt
qt5-qtbase-x11-5.1.1-3.el6.x86_64
qt-4.6.2-26.el6_4.x86_64
qt-sqlite-4.6.2-26.el6_4.x86_64
qt-x11-4.6.2-26.el6_4.x86_64
qt5-qtbase-5.1.1-3.el6.x86_64
ibus-qt-1.3.0-2.el6.x86_64
qt3-3.3.8b-30.el6.x86_64
qt5-qtbase-devel-5.1.1-3.el6.x86_64
qt-devel-4.6.2-26.el6_4.x86_64
qt3-devel-3.3.8b-30.el6.x86_64
所以 qt5 似乎已安装，但 qt4 和 qt3 也是如此（可能其他一些应用程序需要，但这是一个非常简单的系统）。所以现在我已经下载了 QT Creator 源代码，并且正在尝试编译。我给出了 qt5 qmake (/usr/lib64/qt5/bin/qmake qtcreator.pro) 的完整路径，并且有效。但是现在当我发出命令 make 我看到：
[qt-creator-2.8.1-src]# make

所以看起来make包含了qt 3.3头文件I/usr/lib64/qt-3.3/mkspecs/default）。如何告诉 make 或 qmake 使用 Qt5 头文件/库？
我按照下面的建议删除了 qt3-devel 包，现在我的错误更改为：
cd src/ && ( test -e Makefile || /opt/Qt/5.1.1/gcc_64/bin/qmake /usr/src/qtcreator/qt-creator-2.8.1-src/src/src.pro -o Makefile ) && make -f Makefile
make[1]: Entering directory `/usr/src/qtcreator/qt-creator-2.8.1-src/src'
make[1]: *** No rule to make target `/usr/lib64/qt-3.3/mkspecs/default/qmake.conf', needed by `Makefile'. Stop.
make[1]: Leaving directory `/usr/src/qtcreator/qt-creator-2.8.1-src/src'
make: *** [sub-src-make_first-ordered] Error 2
如您所见，make 仍在引用 qt3 的东西。
