RE: VSE10 and GTKmm 2.22

Hi,

 

Iâm not sure if itâs the case in your application, but to build successfully a Gtk or Gtkmm application under MSVC and then run it perfectly, you need to bypass the main function of your application and redirect it to the WinAPI. In plus, you need to add Imm32.lib and msvcrt.lib as additional dependencies.

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.

 

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.

 

 

 

 

 

This would be a more correct version of the function:

 

 

 

 

 

template<typename T>

 

 

std::string toString(const T& data)

 

 

{

 

 

    std::ostringstream num;

 

 

    num << data;

 

 

   return num.str();

 

 

}

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?
