cygwin - 不能执行二进制文件 [英] cygwin - cannot execute binary file

问题描述

我试图运行这两个.data文件从我的c ++代码为我的任务。我已经提供了所有的文件，并且只是为程序实现一些功能（一切都应该能够编译运行make命令）。

I am trying to run these two .data files from my c++ code for my assignment. I have been provided with all the files and are meant to only implement a few functions for the program (everything should be able to compile running the make command).

我使用运行一个MAC，只是刚刚开始使用windows（win 7），因为工作给了我一个免费的笔记本电脑。反正...我安装cygwin，添加了gcc-c ++编译器，gdb和make包我的cygwin。但是当我运行命令 ./ file ./data 时会出现：

I used to run a MAC and only just started using windows (win 7) because work gave me a free laptop. Anyways...I installed cygwin, added the gcc-c++ compiler, gdb and make packages to my cygwin. But when i run the command ./file ./data it comes up with:

bash: ./file: cannot execute binary file

我想安装？请注意，./data是保存我的两个.data文件的文件夹， file1.data 和 file2.data

is there a certain package or something I am suppose to install? Please note, that ./data is the folder that holds my two .data files, file1.data and file2.data

由

g++ -Wall -Werror -02 -c file.cpp
g++ -Wall -Werror -02 -c file-test.cpp
g++ -Wall -Werror -02 -o file file.o file-test.o

推荐答案

使用文件开始命令查看你有什么类型的二进制文件：

Start by using the file command to see what type of binary file you have:

file ./file

如果它不是可执行文件，那就是一个问题。如果它是一个ELF可执行文件，那么它可能是打算在Linux上运行， Windows。例如，比较输出与此命令：

If it is not an executable, that is a problem. If it is an ELF executable then it is probably intended to run on Linux, not on Windows. For example compare the output with this command:

file /bin/bash

它应该告诉你：

/ bin / bash：PE32可执行文件80386（剥离到外部PDB），用于MS Windows

/bin/bash: PE32 executable (console) Intel 80386 (stripped to external PDB), for MS Windows

现在请尝试此命令：

file /cygdrive/c/windows/write.exe

/cygdrive/c/windows/write.exe：PE32 +可执行文件（GUI）x86-64，用于MS Windows

Which says the following: /cygdrive/c/windows/write.exe: PE32+ executable (GUI) x86-64, for MS Windows

我在64位Windows 7安装，这就是为什么它说x86-64。即使这是一个完全与cygwin无关的Windows GUI应用程序，我仍然可以通过命令运行它：

I ran this on a 64-bit Windows 7 installation, which is why it says x86-64. Even though this is a Windows GUI app totally unrelated to cygwin, I can still run it by the command:

/cygdrive/c/windows/write

你真的没有解释如何得到这个二进制文件名为 ./ file 。有可能它是一个目标文件从编译，你还没有链接到一个可执行文件。如果你有一个Makefile，为什么不发布其内容？

You really did not explain how you got this binary file named ./file. Is it possible that it is an object file from compiling that you have not yet linked into an executable? If you have a Makefile, why not post its contents?
