Weird String error (LNK2019)

Well, I've been working on a simple explorer.exe replacement, with it's own simple scripting language.

Everything was going fine until I added a ParseScript, and tokenizeString Function:

Code:

---

PUNCH error LNK2019: unresolved external symbol "class std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> > __cdecl punch::tokenizeString(class std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> >,class std::vector<class std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> >,class std::allocator<class std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> > > >,class std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> >)" (?tokenizeString@punch@@YA?AV?$basic_string@DU?$char_traits@D@std@@V?$allocator@D@2@@std@@V23@V?$vector@V?$basic_string@DU?$char_traits@D@std@@V?$allocator@D@2@@std@@V?$allocator@V?$basic_string@DU?$char_traits@D@std@@V?$allocator@D@2@@std@@@2@@3@0@Z) referenced in function "class std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> > __cdecl punchScript::ParseScript(class punchScript::scriptObject)" (?ParseScript@punchScript@@YA?AV?$basic_string@DU?$char_traits@D@std@@V?$allocator@D@2@@std@@VscriptObject@1@@Z)

Now, from what I can gather, the error is related to the ParseScript function. Here's that and the tokenizeString one (Based on the one from the FAQ):

ParseScript:

Code:

---

string punchScript::ParseScript(scriptObject script)
{
        vector < string > commands;
        punch::tokenizeString(script.commands, commands,  "\n");
       
        for(int i=0; i < (int)commands.size(); i++)
        {
                if(commands[i].find("createWindow ", 0) == 0)
                {
                        string file = commands[i].erase(0, 12); //File for that command
                        char* buff = "";
                        sprintf(buff, "%s", file.c_str());
                        ShellExecute(NULL, "open", buff, NULL, NULL, SW_SHOWNORMAL);
                }
               
                if(commands[i].find("script ", 0) == 0)
                {
                        string file = commands[i].erase(0, 6); //File for that command
                       
                        scriptObject obj = LoadScript(file);
                        return ParseScript(obj);
                }
        }
       
        return "TRUE";
}

tokenizeString:

Code:

---

        string tokenizeString(string str1, vector<string> target, string delimeter="\n")
        {
                          string str = str1;
                          vector <string> tokens; //we'll put all of the tokens in here
                          string  temp;

                          while (str.find(delimeter, 0) != string::npos)
                          {
                            size_t  pos = str.find(delimeter, 0); //store the position of the delimiter
                            temp = str.substr(0, pos);      //get the token
                            str.erase(0, pos + 1);          //erase it from the source
                            tokens.push_back(temp);                //and put it into the array
                          }

                            tokens.push_back(str);          //the last token is all alone
                               
                        target = tokens;
                        return "TRUE";
                }

Sorry for the overly-long post ;)

You didn't need to double post.

I double posted? :S

I *Did* Have a browser crash almost as soon as I clicked "submit", but It didn't display on the page...

*Shrugs* Could a mod please remove this topic, then?

Where is your class definition?

Code:

---

class punchScript::scriptObject
{
        public:
                string file; //Filename
                string comments; //All the Comments, unused
               
                string commands; //List of commands and their parameters, separated by newline
};

I'll attach the other files as well..

I wonder why you bother creating so many namespaces if then you simply throw them all away with the using directives. Might as well forget about namespaces. You will save yourself and anyone else an headache when looking at your code.

Your problem is definitely related to this. std::string is not being seen inside the punch namespace. Fix it.

(I bet you are going to place using namespace std inside punch)

The problem is that the linker cannot find the definition of punch::tokenizeString. This is because you didn't define it in the punch namespace. Add punch:: to the definition of tokenizeString.
