为什么加载共享库时出现错误

Question

我在我的计算机上使用 Fedora 在 /home/... 中从源代码安装了 wxWidgets 3.1.2 我正在尝试构建运行来自 https://docs.wxwidgets.org/stable/overview_helloworld.html 的 Hello world 示例。它通过键入

编译没有任何错误

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

但是在 ./widgetTest 之后我在 shell 中得到了 ./widgetTest: error while loading shared libraries: libwx_gtk2u_xrc-3.1.so.2: cannot open shared object file: No such file or directory。

Whosebug 中的一个答案是在 /usr/lib 中复制整个库，我做到了。然后就不行了，我又遇到了。

(gtk2-devel和gtk3-devel我在安装wxWidgets之前已经安装好了)

ldd ./widgetTest returns:

Answer 1

在打开可执行文件（从同一终端）之前在终端上写入 export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib。为了避免每次都这样做，请将该行添加到您的 ~/.bashrc 或类似文件中。 https://wiki.wxwidgets.org/Compiling_and_getting_started
