Strings as arguments (Undefined reference)

[peaco]

Can anyone tell me what would be causing the following error:

C:\AppData\Local\Temp\cc4arLND.o(.text+0x543):list.cc: undefined ref
erence to `list::fixSize(basic_string<char, string_char_traits<char>, __default_
alloc_template<0, 0> > &, int)'
collect2: ld returned 1 exit status

With the following function.

string fixSize(string in, int len)
{ 
return in; //empty function for now
}

Called in the following way:

string temp = "Test";
temp = fixSize(temp, 20);

Can you provide more code? The compiler thinks you are trying to call a method in some list class.

Your prototype doesn't match your function body.

Your prototype probably looks something like this:

string fixSize(string& in, int len);

And it's part of a 'list' class?

So your function body should look like this:

string list::fixSize(string& in, int len)
//      ^                  ^
//      |                  |
//      |                  note the &, same as your prototype
//     class and scope operator (::)
{
  return in;
}

EDIT: doh, Duoas is faster than me!

Thanks guys, forgot to specify it as part of list.
