Well, as you might expect, this does compile. Ok, so here's a better
picture of what's happening in my code:
include files:
codes.h // contains only the #defines as mentioned above
impl.h // the implementation of a class library
Source
impl.cpp
<file impl.cpp>
#include "codes.h"
#include "impl.h"
#include <iostream>
#include <map>
// then basically what I have above. I declare the map as spelled out
above
// and then define the map as outlined above.
</file impl.cpp>
I tried to compile the program from the command line just to remove VS
from the equation and I'm still getting those errors. I did, "cl /c /
Foimpl.obj." Oh well, it's tomorrow's fight. I may be posting in
here tomorrow depending on what I find.
Thanks,
Andy
