Value. Like this. #include <iostream> #include <map> void func(int* n) { std::cout< m1; //m1["test"] = n; } void main() { func(new int()); } Uncomment the m1... line to uncover the error. On 11 March 2010 17:25, Rutger ter Borg wrote:

I'm having difficulty storing pointers in a std::map. I can't find anything online about it, are std::maps supposed to be able to store pointers?

Sure, as key or as value? Providing a code example might help in this case.

First, this is not really a boost question, so a general C++ list would be a more appropriate forum. That said, running the code -- with the line uncommented -- through codepad gives me only one error: Line 12: error: '::main' must return 'int' I suspect you're using a less-than-stellar compiler. ~ Scott

Thanks guys. I'm embarrassed to say that it was the #include <string> problem.

use boost::ptr_mapstd::string,int or std::map to manange the memory, if you need that. -Thorsten
