Are you in the same directory that hello.c is resided?


ls -la

[william_arackal]

Yes , in the same directory.

[taurus]

While in that directory where hello.c is, can you post the output of this command?


ls -la

What does it look like?


cat hello.c
I assume you compile it as


gcc hello.c

[william_arackal]

I did the prog in gedit as follows
#include<stdio.h>
main()
{
printf("Hello world!\n");
return 0;

}
to compile gave the command
gcc -o hello hello.c

[taurus]

And you still get the same error message about file not found?

[william_arackal]

yes
gcc: hello.c: No such file or directory
gcc: no input files

[taurus]

gcc -o hello ./hello.c
-or-
gcc -o hello ~/hello.c

[william_arackal]

xp@xp-desktop:~$ gcc -o hello hello.c
gcc: hello.c: No such file or directory
gcc: no input files
xp@xp-desktop:~$ gcc -o hello ./hello.c
gcc: ./hello.c: No such file or directory
gcc: no input files
xp@xp-desktop:~$ gcc -o hello ~/hello.c
gcc: /home/xp/hello.c: No such file or directory
gcc: no input files

for your information iam using Ubuntu 8.04

[taurus]

How about no output file.


gcc hello.c

[william_arackal]

xp@xp-desktop:~$ gcc hello.c
gcc: hello.c: No such file or directory
gcc: no input files

[Berserker v7]

This is indeed most odd as i do it all the time!! just try moving your files from home into some other directory, cd into it and then try to compile. and also, is

cat hello.c
working in your home directory?

[sujoy]

now now, you didnt really put in any spaces in the file name did you?

[Ruhe]

xp@xp-desktop:~$ gcc -o hello hello.c
gcc: hello.c: No such file or directory
gcc: no input files
xp@xp-desktop:~$ gcc -o hello ./hello.c
gcc: ./hello.c: No such file or directory
gcc: no input files
xp@xp-desktop:~$ gcc -o hello ~/hello.c
gcc: /home/xp/hello.c: No such file or directory
gcc: no input files

This is Linus's revenge for the fact that the computer is called "xp-desktop" ;)

Try to do this:
create file assert_gcc.sh with the following content


#!/bin/sh

mkdir test_dir;
cd test_dir && touch test_program.c;
echo "
#include <stdio.h>

int main() {
printf(\"test\");
return 0;
}
" > test_program.c;

gcc test_program.c -o test_program;
./test_program


run in console


$chmod +x assert_gcc.sh
$./assert_gcc.sh


I've checked this should work, if not, then it's something mystical
