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?

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

更新虽然我下面所写的是关于共享库的一般答案，但我认为这类消息最常见的原因是因为您安装了一个包，但没有安装该包的-dev版本。

好吧，这不是撒谎——没有libpthread_rt.so。该列表中的1。您可能需要重新配置和重新构建它，以便它取决于您拥有的库，或者安装任何提供libpthread_rt.so.1的库。

Generally, the numbers after the .so are version numbers, and you'll often find that they are symlinks to each other, so if you have version 1.1 of libfoo.so, you'll have a real file libfoo.so.1.0, and symlinks foo.so and foo.so.1 pointing to the libfoo.so.1.0. And if you install version 1.1 without removing the other one, you'll have a libfoo.so.1.1, and libfoo.so.1 and libfoo.so will now point to the new one, but any code that requires that exact version can use the libfoo.so.1.0 file. Code that just relies on the version 1 API, but doesn't care if it's 1.0 or 1.1 will specify libfoo.so.1. As orip pointed out in the comments, this is explained well at here.

在您的情况下，可以使用libpthread_rt.so符号链接。1到libpthread_rt.so。不过，不能保证它不会破坏你的代码并吃掉你的电视晚餐。

尝试安装lib32z1:

Sudo apt-get lib32z1

由于系统无法引用提到的库文件而发生错误。采取以下步骤:

执行locate libpthread_rt.so。1将列出所有具有该名称的文件的路径。假设路径是/home/user/ loco。拷贝路径，执行cd home/USERNAME命令。将USERNAME替换为要运行该文件的当前活动用户的名称。运行vi .bash_profile，在LD_LIBRARY_PATH参数的末尾，就在.之前，添加一行/lib://home/usr/loc:..保存文件。关闭终端并重新启动应用程序。它应该运行。

我使用Ubuntu 18.04

安装相应的-dev包对我来说很有效，

sudo apt install libgconf2-dev

在安装上面的包之前，我得到了以下错误:

turtl: error while loading shared libraries: libgconf-2.so.4: cannot open shared object file: No such file or directory

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
