simple question

[rockprincess]

hi there,

i have a simple question, I just set up my new laptop with kubuntu 12.04 and installed the gcc.

a few weeks ago i wrote some simple c code for school, which I was able to run on the old laptop just fine.

now I have problems executing those files, saying I don't have enough permissions.

theresa@kubuntu:~/c$ ls -lha musik.c
-rwxrwxrwx 1 theresa theresa 349 Dez 25 2011 musik.c

here's the code snippet that i'm trying to run (see it's very simple)

#include <stdio.h>

int main()
{
  printf("****** Meine Musiktitel ******\n\n");
  
  printf("N = Neuen Eintrag hinzufügen \n");
  printf("L = Eintrag löschen \n");
  printf("F = Musiktitel finden \n");
  printf("A = Alle Einträge anzeigen \n");
  printf("B = Programm beenden \n\n");
  
  printf("Ihre Wahl:");
  
  printf("\n\n");
  return 0;
}

When I try to run it by ./musik
I'm getting a "can't execute this file."

earlier i did a gcc -o musik.c musik

this works fine on the old machine.

musik.c is the source code, it will not run itself but can be compiled using gcc into music. It is the output of gcc that you want to pay attention to and to try to run, not the input (source code).

sorry, this was a typo, I meant I was trying to run ./musik

I still get the same error...

If you really did

gcc -o musik.c musik

you should have gotten an error, or musik.c should have been clobbered, or both. The argument following -o is the output file.

i didn't get an error....

should then the correct syntax be?

 gcc -c musik.c -o musik

[sudodus]

If you run

gcc -o musik musik.c

the output file (that is the executable file) is musik.

Then it works when you run ./musik in the same directory (or if you move it to a directory in your path) you can run musik.

It will work wherever you have compatible libraries (unless you compile it including the libraries into the program code).

Ok, I get tons of error messages (unfortunately there are only in german, so I won't post them here)....roughly translated they mean

musik.c:18:582: Warning: Zero-Sign ignored (activated by default)

Could it be that I'm missing some important libraries? Because it's working without any problem on the other machine.

I think you may have different versions of the libraries. But what happens if you recompile from your source code? Or is your error output from when you compile from the source code?

yeah, it's the error output when i run
gcc -o musik musik.c

[sudodus]

yeah, it's the error output when i run
gcc -o musik musik.c

It works for me without warning messages.

$ gcc -o musik musik.c
$ ./musik
****** Meine Musiktitel ******

N = Neuen Eintrag hinzufügen 
L = Eintrag löschen 
F = Musiktitel finden 
A = Alle Einträge anzeigen 
B = Programm beenden 

Ihre Wahl:

Can you run the program afterwards? (If only warning messages, it might be possible to run the program. Error messages will probably stop the compile and link process.)
