Re: Symbol referencing error

[kabir dot patel at uk dot andersen dot com]

I'm confused.....

*pToUpperC is decalred in a header file as:

char *pToUpperC()

and hence looks like a function. But the function body has not been defined
either in the syb2pv.h or syb2pv.c files.

I changed the above to:

char *pToUpperC(char *)

since pNote is declared as:

char *pNote

I also, declared *pToUpperC in my syb2pv.c file, but still get the error
message.

Was this what  I was meant to do?

Thanks

It seems strange to be a GCC related problem.
Are those in the same file (with the funcion before the fprintf) ?
If not, you should use them like this:

***** Solution A) All in one file:
************************************************

// main.c

char *pToUpperC(char *argument) {       // this defines the function
   ...
}

...

fprintf(stream,",%s", pToUpperC(pNote));        // this uses it

// end of main.c

***** Solution B) All in one file, with forward declaration
************************************************

// main.c

char *pToUpperC(char *argument);        // this declares the function

...

fprintf(stream,",%s", pToUpperC(pNote));        // this uses it

...

char *pToUpperC(char *argument) {       // this defines it
   ...
}

// end of main.c

***** Solution C) Two different files
************************************************

// file pToUpper.h
#ifndef pToUpper_h
#define pToUpper_h

char *pToUpperC(char *argument);        // this declares the function

#endif // pToUpper_h
// end of file pToUpper.h

// file pToUpper.c
char *pToUpperC(char *argument) {       // this defines the function
   ...
}
// end of file pToUpper.c

// main.c (where you call pToUpper() from)
#include "pToUpper.h"

...
fprintf(stream,",%s", pToUpperC(pNote));        // this uses the function
...

// end of main.c

*****************************************************
In cases A & B, compile with

gcc main.c -o main

In case C with

gcc main.c pToUpper.c -o main
*****************************************************

If all this sound silly, I'm sorry, but I couldn't think of anything else.
