[ace-users] ACEXML/std::map interaction

[Scott Smith]

OK, I guess it's been too long since I've done a map with a std::string.  I didn't think you needed a comparator functor for a std::string.  Turns out I was wrong (at least on VS2005).  Wasn't an ACEXML problem at all.

    SYNOPSIS:

       I am trying to use ACEXML to parse a file and part of the code in the same module uses a map defined as:

 

            typedef std::map<std::string, someobject> propertyMap;

 

      I am getting the following error on the compile:

Similar messages repeat numerous times.

 

      If I change the std::string key in the map to "const char *", I don't get the compile errors.  If I remove the include of "#include <ACEXML/common/DefaultHandler.h>" (still using std::string as the key into the map), the only compile errors I get are undefines for the ACEXML stuff.  

 

 

The includes I am using look like:

 

#include <ace/OS.h>

#include <ACEXML/common/DefaultHandler.h>

#include "ACEXML/common/FileCharStream.h"

#include "ACEXML/common/StrCharStream.h"

#include "ACEXML/parser/parser/Parser.h"

 

#include <vector>

#include <map>

#include <fstream>

 

 

I've tried changing the order (doing the ace block last).  It doesn't make any difference.  It appears to be some interaction between the ACEXML class and std::string/std::map.  Any thoughts about how I might fix this?
