Undefined reference to "Str::ToInt(unsigned char*)"

Question

I added a new function into my library, and while compiling Gcc refuse to recognize it. Every function works without problem, and this is the only one that give problem.

String.hpp

#ifndef __String_Included__
#define __String_Included__

namespace Str
{
    //Other prototype
    int ToInt(unsigned char*);
};
#endif

String.cpp

int ToInt(unsigned char* Source)
{
    //Codecodecodecodecodecodecode
}

When I call Str::ToInt in the main I get that error. I'm working on Codeblocks 12.11 and Windows 8

Answer 1

You declared Str::ToInt() as a member of the namespace Str but you defined a function outside of any namespace with the same name ToInt(). You need to, at least, Str:: in front of the definition:

int Str::ToInt(unsigned char* Source) { ... }
