I am using Dev C++ and am getting the stated error.  attached is where i include the ConfigFile header that is giving me the grief.

I just can't find an error.  Can someone help?
#include <cstdlib>
#include <iostream>
#include "ConfigFile.h"
#include "Triplet.h"
#include <windows.h>
#include <wininet.h>
#include <string>
#include <fstream>
#include <io.h>
 
using std::string;
using std::cout;
using std::endl;
 
using namespace std;
 
int main(int argc, char *argv[])
{
    //initialize variables
    
    string ssid;
    string ftp_server;
    string username;
    string password;
    string pos_data_loc;
    string pos_data_file;
    string server_file;
    string data_string;
    string prog_call;
    const char* prog_input;
    
    std::time_t now;
    time( &now );
        
    // Load the Config File
	ConfigFile config( "C:/Intelitap/config.inf" );
	
	// Read the various config lines into variables so we can use them in other places	
	//config.readInto( ssid, "ssid" );...

Hi  jamied66,

the linker mentions the ctor ConfigFile::ConfigFile(sdt::string... cannot be found - either it's not implemented or the file where it's implemented isn't compiled or the generated .obj file cannot be found in the lib-path.

Hope that helps,

ZOPPO

>> undefined reference to 'ConfigFile::ConfigFile(sdt::string...
Are you actually building the translation unit that contains the implementation for this class? Have you declared a cosntructor for the class ConfigFile and forgotten to implement it?

The error states "...ConfigFile::ConfigFile(sdt::string" sdt::string should be std::string

Check the file ConfigFile.cpp where you define the constructor for the ConfigFile object and change sdt::string to std::string or you could omit it completely since you have using namespace std;

I didn't write the ConfigFile library myself, no.
i've attached ConfigFile.cpp.  From what I can see it's in good order.

the above typo (sdt instead of std) was just that. a typo on my part.

Again, all help is appreciated.

Thanks.

I figured it out myself.  turns out the files were deleted from the project, so they weren't intialzing, even though the files were still there.  

sorry.

That's what I meant with 'the file where it's implemented isn't compiled' ...

Both Zoppo and I pointed this out in the first 2 answers you received. This being the case I see no valid reason to delete this question.

There are objections:

Both evilrix and me gave the hint that it might be the file in question wasn't compiled - that's exactly what jamied66 'figured out' himself ...

Best regards,
