cannot execute c-program

[Martin V.]

hi,

i want to execute my c-program:

/* time.c */
#include
#include
int main() {
time_t gmt;
(void) time (&gmt);
printf("%d\n", gmt);
}

to print the system time in seconds since 1970-01-01, but it doesn't work. i still become the error message "cannont execute"! can someone help me, please?

thanks

Does it have the execute bit set in it's permissions?

hi pete,

yes the permissions set on 777 (-rwxrwxrwx)

Martin,
if the executable is called timer
ll timer
chmod 755 timer

To run:
./timer

I've just tired it on my system and it worked. The only differences I made were:

#include (instead of stdlib.h)

and I omitted include

the executable called time.out an i changed the permissons on 755 but it doesent work!

Error:

/sbin/sh: ./time.out: cannot execute

Hi:

By default, the execute bit should be set for the object created by the compilation.

What are you running? Did you name the object or let it default to 'a.out' ?

Regards!

Martin,
looks as if your are calling a shell ??
/sbin/sh whcih then calls the time.out
Can you run the time.out from the command line.

/usr/bin/sh
./time.out

also env | grep -i shell

[Martin V.]

i'm running

gcc -g time.c -o time.out

Hi,
although for Linux, please step through:
http://linuxhelp.blogspot.com/2006/04/steps-to-compile-c-c-programs-using.html

On my machine:
$ gcc -g time.c -o time.out
$ ./time.out
1164722127
$ ll time.out
-rwxr-xr-x 1 godronpw users 38912 Nov 28 13:55 time.out

My best guess is that you have somehow configured gcc to output another machines object code format. Do this:

file ./time.out

and

ls -l ./time.out.

and post the results.

That should indicate what is wrong.

[Martin V.]

hi,

the result is:

./time.out: ELF-32
