我能够在我的系统 (RHEL 6.6) 上安装 Qt-5.8.0。安装后，我还将其添加到$PATH。现在，当我输入时，qmake --version我得到以下输出：
QMake version 3.1
Using Qt version 5.8.0 in /usr/local/Qt-5.8.0/lib
当我输入时，echo $PATH我得到以下输出：
/usr/local/Qt-5.8.0/bin:/usr/local/Qt-5.8.0/bin:/root/gcc-4.8.2/bin:/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.121-1.b13.el6.x86_64/bin:/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.121-1.b13.el6.x86_64/bin:/usr/local/sbin:/usr/sbin:/sbin:/usr/local/bin:/usr/bin:/bin:/usr/apache/apache-ant-1.9.9/bin:/root/bin:/usr/apache/apache-ant-1.9.9/bin
但是，qt-creator 没有随 Qt-5.8.0 安装。所以我去了此链接并点击选项“Qt Creator 4.2.1 for Linux 64-bit (93 MB)”。这导致可执行文件qt-creator-opensource-linux-x86_64-4.2.1.run被下载到我的下载文件夹中。
在安装过程中，系统要求我选择安装 qt-creator 的文件夹。因此，我在 中创建了一个名为 的新文件夹qtcreator。安装过程完成后，我通过终端/usr/local进入并输入命令。它给出了以下输出：/usr/local/qtcreator/bin./qtcreator

qt-creator 和 Qt-5.8.0 是否互相不兼容？如果 Qt-5.8.0 可以运行，为什么 qt-creator 不能运行？
是否绝对有必要为 qt-creator 安装libc.so. 6？我以为安装 Qt-5.8.0 可以解决所有这些依赖关系。
