Yes, indeed, and the new incarnation of that template function already looks exactly like yours.

Howerver, that does not explain why adding the gtkmm property sheet would cause std::streamstring to crash.

I am now testing the library using GNU and Code::Blocks, but still, as soon as I add the gtkmm library, I get other errors.

I feel like I am against the wall here, the errors are from the gtkmm libary and there is very little I can do about it.

Â

Any suggestions?

There are indeed several problems with the code, not the least of which is that you are returning a reference to a stack-created temporary object, which is extremely likely to explode in your face at some point.

Â

Â

Â

Â

Â

This would be a more correct version of the function:

Â

Â

Â

Â

Â

template<typename T>

Â

Â

std::string toString(const T& data)

Â

Â

{

Â

Â

    std::ostringstream num;

Â

Â

    num << data;

Â

Â

   return num.str();

Â

Â

}

There is no problem with the code.
#include <iostream>

Â

Â

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. }

Â

Â

However, an error is triggered by line 3. This error started happening as soon as I

Â

Â

added the GTKmm property sheet. If I remove the property sheet from the project, then

Â

Â

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?
