对于所有遇到类似问题的人，请运行以下命令：
LD_LIBRARY_PATH=/usr/local/lib64/:$LD_LIBRARY_PATHexport LD_LIBRARY_PATH
当您编译并安装GCC时，确实会将库放在此处，仅此而已。如常见问题解答所述（http://gcc.gnu.org/onlinedocs/libstdc++/faq.html#faq.how_to_set_paths），您需要添加它。
我假设“如何确保可以找到动态链接的库？”的意思是“如何确保始终找到该动态链接的库”，而不是“不会被找到，您需要这样做”
对于那些不想设置前缀的人，它是/ usr / local / lib64
如果您阅读make输出，则可以在安装gcc时简短地找到此内容：
Libraries have been installed in: /usr/local/lib/../lib32If you ever happen to want to link against installed librariesin a given directory, LIBDIR, you must either use libtool, andspecify the full pathname of the library, or use the `-LLIBDIR'flag during linking and do at least one of the following: - add LIBDIR to the `LD_LIBRARY_PATH' environment variable during execution - add LIBDIR to the `LD_RUN_PATH' environment variable during linking - use the `-Wl,-rpath -Wl,LIBDIR' linker flag - have your system administrator add LIBDIR to `/etc/ld.so.conf'See any operating system documentation about shared libraries formore information, such as the ld(1) and ld.so(8) manual pages.
太简单了！另外，“如果您碰巧想要链接到已安装的库”，是认真的吗？
