C++ 为什么加载共享库时出错

我用Fedora在/home/…中从源代码安装了wxWidgets 3.1.2。。。我正试图从中构建并运行一个Hello world示例。它通过键入来编译，没有任何错误

g++ widgetTest.cpp `wx-config --cxxflags --libs` -o widgetTest

但是在./widgetest之后我得到了./widgetest:加载共享库时出错：libwx_gtk2u_xrc-3.1.so.2:无法打开共享对象文件：我的shell中没有这样的文件或目录

stackoverflow中的一个答案是在/usr/lib中复制整个库，我做到了。然后它不起作用了，我又得到了同样的结果

在安装wxWidgets之前，我已经安装了gtk2-devel和gtk3-devel

ldd./widgetest返回：

在从同一终端打开可执行文件之前，在终端上写入导出LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib。为了避免每次都要这样做，请将该行添加到~/.bashrc或类似代码中。

请编辑您的问题，将wx config-cxxflags-libs的输出包括在内，好吗？您在哪里安装了目录为libwx_gtk2u_xrc-3.1.so.2的库？请在执行命令之前，尝试在终端中导出LD_library_PATH=/PATH/to/library:$LD_library_PATHlibrary@MikevanDyke不起作用sameAm I right是libwx_gtk2u_xrc-3.1。所以。2是一种依赖关系？它是一个用于根据源文件。wc配置的输出。。。有一个-lwx_gtk2u_xrc标志或其他平面，我们不知道，因为您没有发布指示gcc链接库的内容。检查系统上是否有libwx_gtk2u_xrc-3.1.so*文件，如/usr/lib或/usr/lib64或/usr/local/lib等。如果没有，请安装它。
