Bash: Cannot execute binary file

Bash: Cannot execute binary file

[independentt]

Ok here is my problem I used to be able to run bIRCD on a shell before. But
now first time I try cygwin, I WGET
http://ircd.bircd.org/bewareircd-linux.tar.gz and unzip it, edit the config
files. And now I try to execute it using (.) ./BIRCD and it says BASH:
Cannot execute binary file. I have full access to the file and when I type
file bircd it says ELF 32-bit LSB executable, Intel 80386, version 1
(GNU/Linux), statically linked, stripped.
I am a windowsx86 vista user 

Hope you help me thanks.

I could be off-base, but two quick thoughts:

1) Do the file permissions include x (executable) permission
as shown by ls -l?

2) Above you used ./BIRCD and bircd interchangeably for the names,
but in cygwin names can be case-sensitive. Have you tried the
case (upeer vs. lower) of the letters of the name exactly as
ls reports?

ls -l bircd  shows this message
-rwxr-xr-x 1 Admin01 None 577660 Aug 13  2010 bircd

I meant i did ./bircd in the fist case

Thanks for reply

If you go to http://cygwin.com/ and look under "...isn't it?"  you'll see:

Cygwin is not:

	* a way to run native Linux apps on Windows.  You must rebuild your
	application from source if you want it to run on Windows.

If file says "ELF 32-bit LSB executable, Intel 80386 version 1
(GNU/Linux)", it means it's a Linux file.  That means that you have to
build a Cygwin/Windows version of bircd.  What you have is not a Cygwin
version.

If you're asking me: I don't know.  But, your first place to check would
be the bircd.org web site.

Re: Bash: Cannot execute binary file

Why not just use the Windows version and invoke it from
cygwin (if cygwin is the environment from which you
want to do that)?  It is easy to invoke Windows programs
from cygwin; you just need to remember to format any
arguments in the form the Windows program wants.  To
that end, cygpath is a useful utility, e.g.:

function acrobat () {
   command acrobat $(cygpath -wa ${1})
}

in your .bashrc file allows you to invoke Windows
acrobat with a path rewritten from cygwin format
to Windows format. This can be improved to check for
presence of the argument ${1}, etc., but perhaps
you get the idea.

- You should probably also add some quotes, in case your paths have spaces.
- A complete path to acrobat will avoid needing to have it in your path.
- Using cygstart will get you back to your command prompt.

function acrobat () {
    if [ -f "${1}" ]
    then
        cygstart '/path/acrobat' "$(cygpath -wa "${1}")"
    else
        echo "error: file `${1}' not found!"
    fi
}

Note:  I have not tested the above.  Debugging is left as an exercise for
the user.

- You also might look at cyg-wrapper.sh, found here:
    http://hermitte.free.fr/cygwin/
  Note:  I don't use it so YMMV.

Good luck.

Hi,

This problem is very frequently occuring irrespective of executable.
A new laptop, windows7, downloaded the Cygwin with utmostcare in slecetingthe 
desired and permissions.
Wrote simple programe in c ( simple such that: print "hello world").
while try to run the executable created throws the error: cannot execute 
binary file.

flow is like follows:
C file created: Hello.c ( full permissions)
Compiled and linked: gcc -c Hello.c -o helloTest
chmod 777 helloTest
./helloTest 
bash: ./helloTest : cannot execute binary file

Tried all options which I know, googled no clue.
I tried in other machines too, same error.

I think something is missing, earlier used to work on my old system. But last 
few months I tried several times reinstalling, new machines which I got for 
personal use. 

Is there any solution or inputs please.

regards,
ramana

start from here:

further questions:
- local disk or network disk ?
- results of "ls -l helloTest" ?

You get what you asked for with -c, an object file. Instead use

    gcc Hello.c -o helloTest

which creates an executable.
