How to execute a file in Cygwin?

Question

How can I execute a.exe using the Cygwin shell?

I created a C file in Eclipse on Windows and then used Cygwin to navigate to the directory. I called gcc in the C source file and a.exe was created. I would like to run a.exe .

Answer 1

./a.exe at the command line

Answer 2

you can just call by typing the file name. You may need to call. /a.exe, because the current directory is usually not in the path for security reasons.

Answer 3

just enter. / a in shell

Answer 4

To execute the file in the current directory, the following syntax is used: ./foo

As allain mentioned, ./a.exe is the right way to execute a.exe in the working directory using Cygwin.

Note. You can use the -o option to cc to specify your own output file name. An example of this might be: cc helloworld.c -o helloworld.exe .

This is generally. For your program running on Windows, it must end with .exe, the "C programming language" was not written with Windows programmers. As you have seen, cygwin emulates many, but not all, of the features of the POSIX environment.

Answer 6

gcc under cygwin does not generate a Linux executable like “ELF 32-bit LSB executable”, but it does generate a Windows executable like “PE32 executable for MS Windows”, which has a dependency on cygwin1.dll, so it needs to be run under the cygwin shell . If you need to run it under the dos prompt yourself, they should be in your Windows PATH. Cyberwin1.dll.

-AD.

Answer 7

Apparently, gcc does not behave as described in the C programming language, which says that the cc helloworld.c command creates a file called a.out, which can be launched by entering a.out at the prompt.

Unix didn’t behave like this by default (so you can just write an executable name without ./in front) for a long time. It is called a.exe, because otherwise Windows will not execute it, since it gets file types from the extension.

Answer 8

Just call him

Make sure it is found (path).

Answer 9

When you start working in Cygwin, you are in the "/ home / Administrator" zone, so add the a.exe file there.

Then at the command prompt:

cd a.exe

It will be read by Cygwin and you will be asked to install it.
