VC++ 6.0 errors

Expand Post »

Hi Everyone
I am new to vc++ 6.0 graphics programming. I am getting some errors of a program which i am trying to compile. i have added all the dependencies but not able to figure out why I am getting the following errors. Any suggestions.

Threading.cpp

Re: VC++ 6.0 errors

my guess is that you forgot to include one or more header files. You should post the line(s) the compiler is complaining about.

Re: VC++ 6.0 errors

All the errors are from these codes. I have no clue why? Thanks in advance.

C++ Syntax (Toggle Plain Text)
std::map<std::string, std::map<std::string, c_PerformanceMeasurement> >::iterator iClass = mPerformances.find(Class);
std::map<std::string, std::map<std::string, c_PerformanceMeasurement> >::iterator iClass = mPerformances.find(Class);

C++ Syntax (Toggle Plain Text)
if (iClass != mPerformances.end())
 {
  std::map<std::string, c_PerformanceMeasurement>::iterator iPerformance = iClass->second.find(Name);
  if (iPerformance != iClass->second.end())
  {
   return iPerformance->second;
  }
 }
if (iClass != mPerformances.end())
 {
  std::map<std::string, c_PerformanceMeasurement>::iterator iPerformance = iClass->second.find(Name);
  if (iPerformance != iClass->second.end())
  {
   return iPerformance->second;
  }
 }

Re: VC++ 6.0 errors

does second.find(Name); return an iterator of the correct type? such as std::map<std::string, c_PerformanceMeasurement>::

looks like the variable mPerformances is a const map<...
you have to change ...>::iterator to ...>::const_iterator

Yes, it does. Actually, this code is developed by one of the developer of my company. The code runs ok in his machine. But when I try to compile it in my machine, it gives me error. I made sure that all the settings are same as his but same old errors. any suggestions?
