问题发生是因为您在发行版的/usr/lib/x86_64-linux-gnu中安装了Qt，默认情况下ld将使用它。为避免此类问题，您可以使用-rpath进行编译，或使用LD_LIBRARY_PATH=/path/to/your/Qt/libs/location运行以帮助链接器找到所需的Qt版本。
答案 1 :(得分：1)
解决此问题的最简单方法是安装QT开发人员包：
sudo apt-get install qt5-default
这将安装您需要的软件包。
答案 2 :(得分：1)
安装Qt5.x.0（您需要的版本），找到安装路径并将所有文件gcc_64/lib/*复制到
/usr/lib/x86_64-linux-gnu/*
