C++ file cfx_pmta.cxx won't compile - c++

Question

I am trying to compile the PMTA cfx_pmta.cxx file so I can make some changes but I can't get it to compile before I have even made any changes.
Here are the includes at the to of the file:

Any help would be a great!! Just need to be able to get it to compile the DLL and then I can make the changes needed.
Also I'm not a C++ dev so trying to get my head round it, so go easy.

Answer 1

std::cout is a output stream which is defined within the <iostream> header.
in order to use std::string objects you have to include the <string> header
Try adding:
#include<iostream>
#include<string>
In your cxx file.

Answer 2

After some reading I decided to try the Command Line compiler and to my amazement it compiled fine.
So if anyone is intrested in how to recompile the cfx_pmta.cxx file for PMTA to change the Cold Fusion custom tag code run the following command (obviously changing path to match your file locat
cl /LD /MT /EHsc /IC:\path\api\include /IC:\ColdFusion8\include /D "_WIN32" C:\path\api\cfx_pmta.cxx /link C:\path\api\lib\pmta.lib ws2_32.lib advapi32.lib
