问题描述：

在 ubuntu 15.10 上执行 eiskaltdc++ 时出现以下错误：

Qt 版本

~$ which qmake
/opt/Qt5.6.0/5.6/gcc_64/bin/qmake
~$ qmake -version
QMake version 3.0
Using Qt version 5.6.0 in /opt/Qt5.6.0/5.6/gcc_64/lib
~$ echo $PATH
/opt/Qt5.6.0/5.6/gcc_64/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games

我能够使用 Qt Creator 成功编译应用程序。

编辑

运行 ldd 给了我这个。我不确定如何解释这个

请提出解决方案。提前致谢。

解决方案 1：

出现问题的原因是您从发行版中安装了 Qt，/usr/lib/x86_64-linux-gnu而 ld 默认会使用该发行版。为了避免此类问题，您可以使用进行编译-rpath或运行，LD_LIBRARY_PATH=/path/to/your/Qt/libs/location以帮助链接器找到所需的 Qt 版本。
