加载共享库时出现Linux错误:无法打开共享目标文件:没有这样的文件或目录

程序是Xenomai测试套件的一部分，从Linux PC交叉编译到Linux+Xenomai ARM工具链。

.1是文件名的最后部分吗?这到底是什么意思?

当前回答

cd /home/<user_name>/
sudo vi .bash_profile

把这几行加在末尾

LD_LIBRARY_PATH=/usr/local/lib:<any other paths you want>
export LD_LIBRARY_PATH

您的库是一个动态库。您需要告诉操作系统在运行时可以在哪里定位它。

为了做到这一点，我们需要做这些简单的步骤:

Find where the library is placed if you don't know it. sudo find / -name the_name_of_the_file.so Check for the existence of the dynamic library path environment variable(LD_LIBRARY_PATH) echo $LD_LIBRARY_PATH If there is nothing to be displayed, add a default path value (or not if you wish to) LD_LIBRARY_PATH=/usr/local/lib We add the desired path, export it and try the application. Note that the path should be the directory where the path.so.something is. So if path.so.something is in /my_library/path.so.something, it should be: LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/my_library/ export LD_LIBRARY_PATH ./my_app

我在Linux x86上使用Eclipse CDT运行应用程序时遇到了这个错误。要解决这个问题:

在Eclipse中: 执行命令as ->执行配置命令->环境设置路径 LD_LIBRARY_PATH = / my_lib_directory_path
