STL map problem
Author
Hello, I'm a newbie using STL, and have been trying to setup a map for resource management within my game, but keep getting a linkage problem. Here is the code for the header file:
I thought it had something to do with the fact that I was storing pointers, but even a simpl std::map<std:string, std:string> gives an error.
Any help is appreciated.
Thanks.
I bet the linker is complaining about the static instance; "unresolved external" or some such.
steeg, your static CResManager instance; is only a declaration, you still need to add CResManager CResManager::instance; to some CPP file to define the variable.

yes, I have that on my .cpp file, which is just blank right now:
#include "ResManager.h"CResManager CResManager::instance;CResManager::CResManager(void) {}CResManager::~CResManager(void) {}and the error I am getting (say when I use std::map<std:string, std:string> is:
ResManager.obj : error LNK2019: unresolved external symbol __imp___CrtDbgReportW referenced in function "public: bool __thiscall std::_Tree (and it goes on for lines and lines...)

This is a build settings issue. Creating a new project and copying your source files into it should fix it.
A quick [google] turns up people who have had the same problem (and had other less drastic possible solutions, if you have a bunch of custom build settings you'd rather not trash)
Or you can make sure that "Ignore All Default Libraries" is set to No (Project->Properties->Configuration Properties->Linker->Input).

you can try gdb and do a stack trace.
He is having linker errors, not runtime errors.
