std::map<std::string,int> Problem

[tombert]

Hi all,

can someone please tell me what's wrong with that code?
I am using gcc 4.7 from MinGW, under 4.6 it seemed to have compiled correctly.

The error is:
: error: no matching function for call to 'std::map<std::basic_string<char>, int>::insert(std::string&, int)'

Example:
class TDir {
typedef std::map<std::string,int> Subdirs;
public:
TDir(){}
~TDir(){}
void getDir(std::string name) {
Subdirs t;
t.insert(name,0);
}
};

^^^^^^

It's strange gcc4.6 compiled that code.

try with std::make_pair from <utility>:
t.insert(std::make_pair(name,0));

 

[Juha Nieminen]

t.insert( std:air<std::string,int>(name,0) );

How about just

t.insert( std::make_pair(name,0) );

Or even easier:

t[name] = 0;
