“没有这样的文件或目录"但它存在 [英] "No such file or directory" but it exists

问题描述

我只想从命令行运行一个可执行文件，./arm-mingw32ce-g++，但随后我收到了错误消息，

I simply want to run an executable from the command line, ./arm-mingw32ce-g++, but then I get the error message,

bash: ./arm-mingw32ce-g++: No such file or directory

我正在运行 Ubuntu Linux 10.10.ls -l 列表

I'm running Ubuntu Linux 10.10. ls -l lists

-rwxr-xr-x 1 root root  433308 2010-10-16 21:32 arm-mingw32ce-g++

使用 sudo (sudo ./arm-mingw32ce-g++) 给出

Using sudo (sudo ./arm-mingw32ce-g++) gives

sudo: unable to execute ./arm-mingw32ce-g++: No such file or directory

我不知道为什么操作系统在文件存在时甚至看不到它.有什么想法吗?

I have no idea why the OS can't even see the file when it's there. Any thoughts?

推荐答案

此错误可能意味着 ./arm-mingw32ce-g++ 不存在(但确实存在)，或者它存在并且是内核识别的动态链接可执行文件，但其动态加载程序不可用.您可以通过运行 ldd/arm-mingw32ce-g++ 来查看需要什么动态加载器；任何标记为 not found 的都是您需要安装的动态加载程序或库.

This error can mean that ./arm-mingw32ce-g++ doesn't exist (but it does), or that it exists and is a dynamically linked executable recognized by the kernel but whose dynamic loader is not available. You can see what dynamic loader is required by running ldd /arm-mingw32ce-g++; anything marked not found is the dynamic loader or a library that you need to install.

如果您尝试在 amd64 安装上运行 32 位二进制文​​件:

If you're trying to run a 32-bit binary on an amd64 installation:

• 在 Ubuntu 11.04 之前，安装包 ia32-libs.莉>
• 在 Ubuntu 11.10 上，安装 ia32-libs-multiarch.
• 从 12.04 开始，安装 ia32-libs-multiarch，或除了 :amd64 包之外，选择一组合理的 :i386 包.

• Up to Ubuntu 11.04, install the package ia32-libs.
• On Ubuntu 11.10, install ia32-libs-multiarch.
• Starting with 12.04, install ia32-libs-multiarch, or select a reasonable set of :i386 packages in addition to the :amd64 packages.
