MyClass does not name a type. What the compiler was too polite to say: You idiot, you forgot to specify the namespace. This message can be perplexing at first because you can see either the #include or forward declaration for your class and you know you've spelled it correctly but the message persistently says MyClass does not name a type. Mais mon debugger m'affiche: 'Batiment' does not name a type Je crois que c'est un probleme de header, mais j'en ai mis partout et pourtant ca ne fonctionne pas. Peut-etre que je n'ai mis de trop. Je vous passe mon code.

I have a class named backgroundObstacleManager that I created and another class Pit that have to interact with each other.
OK, I've seen this error explained at least 100 times on the net. But in every case, it seems to be an error of #including <string.h> instead of <string> or metioning string instead of std::string. But, I've done all those things. And it still does not work.
By way of background: I am a LONG time newbie C++ programmer (meaning that I write code in spurts and then not at all for several years, which means that whenever I advance beyond newbie status, I slide back after time). I have also traditionally been coding using the old Borland compiler (which works, even if it is ancient, but I like the IDE). I have now been trying to come into the 21st century by using gnu c++ (g++ and mingw). The code problem that I am presenting compiles using the Borland compiler, but gives me the error message only when I try to compile with g++.
The problem code:
You can see I use std::string and have this header protected with an #ifndef envelope. I am not using namespace in the header, which people tell me is a bad thing to do.
So, any suggestions??
Thanks for your time.
The C standard headers time.h and stdlib.h should not be used in C++ code. You need to using the C++ versions of these headers, which are included with #include <ctime> and #include <cstdlib>, respectively. Then, any function from these headers must also be prefixed with std:: like all other C++ standard library classes and functions.
Then, the _strdate and _strtime functions are not standard C/C++ functions. They are C functions provided by old Microsoft headers (included by time.h), and you should not use them if you want to write portable code (e.g., be able to use another compiler or OS beside Microsoft or Borland). The standard C++ equivalent of that code is this for example (using the '>strftime function):
If you look at the documentation for strftime that I linked to, you will find further options for formatting the date / time printout.
I've been trying to write a class called Point, with a file Point.cpp including a header file Point.h . I tried to set a global variable of type Point called ORIGIN, however I get an error message saying 'error: ‘ORIGIN’ does not name a type'
Point.h is as follows:

Point.cpp is as follows:
I have a feeling the error has something to do with the part in Point.cpp where I try to assign values to ORIGIN's x and y member variables, although I'm not quite sure how to fix this :(
any help would be appreciated, thanks!
I managed to fix this problem, but now it seems that I'm still having a problem with overloading the ' << ' operator. I get an error message saying
no match for ‘operator<<’ in ‘cout << '('
What am I doing wrong here?? Again, any help would be appreciated, thanks!
