General / Precompiled SFML 1.6 for 64 Bit Windows

Solved my compilation issues. The 64 bit OpenAL can be found by downloading the OpenAL SDK installer.

Window / x64 - GetEvent crash

« on: December 09, 2011, 11:26:15 pm »

Hey Laurent.

I found the problem

In WindowImplWin32.cpp

Code: [Select]

       // Get WindowImplWin32 instance (it was passed as the last argument of CreateWindow)
        longThis = reinterpret_cast<long>(reinterpret_cast<CREATESTRUCT*>(LParam)->lpCreateParams);

That is wrong, since long is 32 bit on x64 but pointers are 64 bit.

You should change it to:

 

Code: [Select]

      LONG_PTR This = reinterpret_cast<LONG_PTR>(reinterpret_cast<CREATESTRUCT*>(LParam)->lpCreateParams);

After changing this it works fine.

I noticed this problem migth occur in a few other places, e.g. the first constructor. with SetWindowLongPtr?

Window / x64 - GetEvent crash

« on: December 09, 2011, 10:20:18 pm »

I have an application that works well in 32 bit, however I'm having some problems with 64 bit.

The GetEvent method seems to crash my application.

I have compiled SFML 1.6 as a static library for x64 with /MDd.

I have traced the problem down to the very first call of GetEvent and then deeper into the code:

Code: [Select]

void WindowImplWin32::ProcessEvents()
{
    // We update the window only if we own it
    if (!myCallback)
    {
        MSG Message;
        while (PeekMessage(&Message, NULL, 0, 0, PM_REMOVE))
        {
            TranslateMessage(&Message);
            DispatchMessage(&Message); // access-violation
        }
    }
}

Where Message has the following values:

message = 799
wParam = 1
lParam = 0
time = 25335545
pt = {x=611, y=411}

Any ideas what could cause this our how to debug it?

If I just skip the GetEvent calls the application runs fine and the window is rendered, but it of course wont respond to any interaction.

EDIT:

On second thought this should proably go into the "Window" forum.

I found and managed to compile freetype as required However, openal still remains a mystery.

I'm having trouble building Debug DLL using the solution found in ingwiks link. I get link error towards opengl and freetype. Any ideas how to fix it?

Audio / Change OpenAL Device

« on: January 16, 2011, 01:01:08 pm »

I'm using SFML 1.6 in my project and I would like to be able to choose which output device should be used by sf::SoundStream.

As SFML 1.6 doesnät seem to support this I'm wondering if there is a way that I can change the the active al device to one I have created through something like alcMakeContextCurrent.

Is this possible? And if so I'd appreciate some tips on how to go about it.

SFML wiki / [Sources] Video Integration with ffmpeg (Updated: 1.03)

Suggestion. If you use PIX_FMT_RGBA in sws_getContext (and other parts)  you can avoid the copy in UpdateImage.

Thanks for the help.

Graphics / OpenGL with no or hidden window

Thanks. Almost there.

One last problem. How do I swap buffers using the context? It seems to create a dummy window in the background. However it is a private member and I cannot call Display on it.

And if the main is unavailable... how do I add an ogl context to a new thread without creating a window?

I'm using SMFL to do some gpgpu computing... which doesnt require a window however a ogl context is still needed.

In what ways can I run OpenGL SFML with no or someway hidden window?

Audio / Audio streaming problems

Wouldn't it be better if the Sleep time depended on the sample rate. Instead of a fixed value.

I can modify 1.6. I'm working on a business critical application and would prefer to keep using 1.6 while 2.0 is maturing.

Could you send me the required changes?

Thank you.

EDIT:

Found it on SVN. Thx.
