GCC compiler error messages.

This is a list of compiler error messages I have hit and the method used to clear them.

warning: comparison between pointer and integer

Maybe OK. This was generated from 'if (strstr(line,"word") != NULL )' strstr returns NULL or pointers, I was only interested in the fact that a string had been found, not where it was.

`floppyto.c:782: parse error at end of input

floppyto.c is the program name, 782 is the line number but it is one greater then the file length. This is because of unbalanced {} or unbalanced comments /* */

parse error before `printf'

Missing ; before this statement.

Segmentation error.

You have attempted to access protected storage or overwritten something important!

subscripted value is neither array nor pointer

Attempted to subscript a scalar variable.

`j' undeclared (first use this function)

Declare the variable.

/usr/lib/crt0.o: Undefined symbol _main referenced from text segment

Generated when main() is missing. I have seen this twice.

When there was a syntax error in an included header file.
And when the C source file was missing in the gcc command!

Undefined symbol _initscr referenced from text segment

Called a function but have not supplied it or the library that contains it with an #include statement.

unterminated `#if' conditional

#endif preprocessor required.

warning: passing arg 1 of `cpystr' makes integer from pointer
without a cast

This is the code causing the problem:

void cpystr( char item);
main()
{
   char src[]="martin leslie";
   cpystr(src);
}
   cpystr(char item)
{
}

It should be....

void cpystr( char item[]);
main()
{
   char src[]="martin leslie";
   cpystr(src);
}
   cpystr(char item[])
{
}

conflicting types for `Alex'
previous declaration of `Alex'

Alex has been declared in two enum statements. Here is the code

parse error before `1'
At top level:
warning: data definition has no type or storage class
parse error before string constant
warning: data definition has no type or storage class

There is a conflict between enum and #define statements. Here is the code
