When I build my source code it works fine. But when I execute the code it gets an error.

ZeroLink: unknown symbol '_menu'

Executable “Number Game ” has exited due to signal 6 (SIGABRT).

Can some one please tell me whats wrong. I tried this program earlier and it worked fine.

Does this error happen when executing your program in XCode or when you try to run it as a standalone program?

I've run into an issue where the program will run through XCode but won't run as a standalone. I don't know why this happens. When it does happen though I have to create a blank new project, then import all my files and recompile. Then it works fine.

You're using ZeroLink. This means linking errors are delayed to runtime.

Yes, but you should get a warning at least during compilation.
The problem is that the compiler can't find the menu() function. Does it exist?

Heres my code. All I am trying to do is create a simple menu with a switch statement. I am just learing C.



#include <stdio.h>
#include <stdlib.h>
#include <time.h>

#define DELAY 150000

int menu(void);
void delay(void);

int main()
{
while(1)
{
switch(menu())
{
case 1:
{
puts("\nExicuting choice 1...");
delay();
}
case 2:
{
puts("\nExicuting choice 2...");
delay();
}
case 3:
{
puts("\nExicuting choice 3...");
delay();
}
default:
{
puts("\nNot a choice, try again.");
}
}
}
return 0;
}

First off, where are your menu() and delay() functions?

Also, all your case statements should end with a break; statement. Otherwise your code will execute every case statement after the first one it enters.

One more thing, It's "Executing" not "Exicuting".

I believe you mean menu() and delay().

Oops! Fixed. That's what I get for trying to correct a spelling error. The point still stands though. If you have a function prototype without the accompanying function your program isn't going to work.

Oops! That could be a problem . I'll try puting that in and running it, and i dont really pride myself on spelling .
