Qt应用程序中与Qt版本相关的运行时错误
Qt应用程序中与Qt版本相关的运行时错误
提问于 2018-06-16 06:05:09
我正在使用Qt Creator在Linux KDE neon上开发和运行一个应用程序。
我的应用程序突然拒绝打开一些URL，这是一个以前可以正常工作的功能。我没有改变任何东西，所以我猜是一些KDE霓虹灯更新破坏了它。
当调用该函数时，我得到以下调试输出：

解决方案应该是在链接应用程序时使用-rpath。我的应用程序是使用以下命令行构建的：
gcc -Wl,-rpath,/home/<user>/Qt/5.10.0/gcc_64/lib .....在我看来没问题。另请将以下内容传递给gcc：
-L/home/<user>/Qt/5.10.0/gcc_64/lib这里缺少什么？为什么我的应用程序依赖于Qt 5.11库，而构建过程设置了正确的Qt 5.10路径？

-rpath将r运行时库搜索路径硬编码到可执行文件或库中。它不会影响链接器搜索路径，因此您的应用程序与系统Qt库相链接。您应该通过-L选项传递相同的路径：
gcc -Wl,-rpath,/home/<user>/Qt/5.10.0/gcc_64/lib -L/home/<user>/Qt/5.10.0/gcc_64/lib ...以下是更多信息：
