Problem with deleting sf::Font pointer

[Nerote]

Hello, i ran into some trouble when playing around with the sf::Font class.

sf::Font* font = new sf::Font();

delete font;
 

This is not working, just wondering if there's something i've missed?

Thanks!

You mean that this code doesn't work? (and what does "doesn't work" mean exactly?)

#include <SFML/Graphics.hpp>

int main()
{
    sf::Font* font = new sf::Font();
    delete font;
    return 0;
}

If it works, then please provide a complete code that reproduces the problem.

Manual memory management is in C++ kind of depreciated, much nicer is to allocate things on the stack and if it's not possible then use a smart pointer, which will automatically free the resource thanks to RAII.

I tried to allocate and delete in the main function.
I am using Visual Studio 2012 and it breaks when calling delete in "dbgheap.c"

extern "C" _CRTIMP int __cdecl _CrtIsValidHeapPointer(
        const void * pUserData
        )
{
        if (!pUserData)
            return FALSE;

        if (!_CrtIsValidPointer(pHdr(pUserData), sizeof(_CrtMemBlockHeader), FALSE))
            return FALSE;

        return HeapValidate( _crtheap, 0, pHdr(pUserData) );
}
 

Im having a hard time describing my problem any better.
Thanks.

Did you recompile SFML? You need to (or get an unofficial nightly build) , since there's no precompiled version for VS2012.

Are you using libraries built for your compiler version?

[Nerote]

Yes I have recompiled SFML for this version.

Show the actual, complete, minimal int main() which causes the problem.
Is that enough to crash?

int main()
{
sf::Font * font=new sf::Font();
delete font;
}

Are you sure that you don't mix debug and release?

[Nerote]

This code does not work.

#include <SFML\Graphics.hpp>


int main()
{
        sf::Font* font = new sf::Font();
        delete font;

        return 0;
}
 

And im not mixing release and debug.

I just got some response from a friend who said as previous poster stated with putting them on the stack. So i guess i should avoid pointers with the fonts.

Although im a bit confused why i am not able to delete sf::Font's.

The problem is not whether you should do it or not, this code should work. If it doesn't, it means that you have an environment issue that must be fixed, otherwise you won't be able to develop anything with SFML.

How did you recompile SFML, what options did you change in CMake?

[Nerote]

I followed the tutorial on this website when i recompiled it.
I set the CMAKE_BUILD_TYPE to Debug, rest as the default.
Generator set to Visual Studio 11.
