翻译下面的英文 Add a directory to the runtime library search path. This is used when linking an ELF executable with shared objects. All -rpath arguments are concatenated and passed to the runtime linker, which uses them to locate shared objects at runtime. The -rpath option is also used when locating shared objects which are needed by shared objects explicitly included in the link; see the description of the -rpath-link option. If -rpath is not used when linking an ELF executable, the contents of the environment variable "LD_RUN_PATH" will be used if it is defined

将一个目录添加到运行时库搜索路径中。这个选项用于将ELF可执行文件与共享对象链接。所有-rpath参数将会被串联在一起，并传递给运行时链接器，用于在运行时定位共享对象。在链接中，如果共享对象需要其他共享对象的支持，也会使用-rpath选项。如果在链接ELF可执行文件时没有使用-rpath，且环境变量"LD_RUN_PATH"已定义，则会使用该变量的值作为运行时库搜索路径。

安装gcc 4.9时报错，错误提示Libraries have been installed in: /usr/local/lib/../lib64 If you ever happen to want to link against installed libraries in a given directory, LIBDIR, you must either use libtool, and specify 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 for more information, such as the ld(1) and ld.so(8) manual pages.

这个错误信息是在安装 gcc 4.9 的过程中出现的，它提示你安装了一些库文件，并给出了一些链接库的建议。

一般来说，正确的解决方法是将 `/usr/local/lib/../lib64` 目录加入到系统的动态链接库搜索路径中。可以通过以下几种方式实现：

1. 使用 `LD_LIBRARY_PATH` 环境变量。可以将以下命令添加到 shell 配置文件（如 ~/.bashrc）中，使其永久生效：

   export LD_LIBRARY_PATH=/usr/local/lib/../lib64:$LD_LIBRARY_PATH

2. 使用 `LD_RUN_PATH` 环境变量。可以将以下命令添加到 shell 配置文件中，使其永久生效：

   export LD_RUN_PATH=/usr/local/lib/../lib64:$LD_RUN_PATH

3. 使用 `-Wl,-rpath` 链接选项。在编译链接时，可以使用以下命令：

   gcc -o target target.c -L/usr/local/lib/../lib64 -Wl,-rpath=/usr/local/lib/../lib64

4. 将 `/usr/local/lib/../lib64` 目录添加到 `/etc/ld.so.conf` 配置文件中，并执行 `ldconfig` 命令更新动态链接库缓存：

   echo "/usr/local/lib/../lib64" | sudo tee -a /etc/ld.so.conf
   sudo ldconfig

以上几种方法中，第四种方法是最常用的。你可以先尝试这个方法来解决问题。

报错内容显示为Hint This means that multiple copies of the OpenMP runtime have been linked into the program. That is dangerous, since it can degrade performance or cause incorrect results. The best thing to do is to ensure that only a single OpenMP runtime is linked into the process, e.g. by avoiding static linking of the OpenMP runtime in any library. As an unsafe, unsupported, undocumented workaround you can set the environment variable KMP_DUPLICATE_LIB_OK=TRUE to allow the program to continue to execute, but that may cause crashes or silently produce incorrect results.
