There is no problem with the code.
#include <iostream>
1. template< typename T>
2. std::string& toString(const T& data){
3. std::stringstream num(std::stringstream::out);
4. num << data;
5. return run.c_str();
6. }
However, an error is triggered by line 3. This error started happening as soon as I
added the GTKmm property sheet. If I remove the property sheet from the project, then
the applicatin compiles without any problem.
So, the problem is the gtkmm and not VC++ or the IDE in my Win7.
Is there anyone here having the same problem?
