Window / getting game pad events without showing a window

« on: November 19, 2010, 04:35:23 pm »

I want to use SFML for platform-independent gamepad support, but I already have a working GUI using Qt. I looked at the Qt sample in SFML-1.6, which seems to be very close to what I want.

Question 1: Does this still work with SFML-2 from svn? More specifically: Is SFML's WindowHandle type still compatible with Qt's WId type? On all supported platforms? (This is at least how I understand the usage in the 1.6 sample.)

Question 2: Is this possible at all? I think, I would need to create a Window-object, that does not open an actual window on the screen, nor creates an openGL-context.

Any insight appreciated.

C / CSFML and cmake configuration problem

« on: November 18, 2010, 09:31:49 pm »

Hi!

I just saw, that sfml switched to cmake in the version 2 branch. That's great! I have a problem building CSFML, though: When trying to do the cmake configuration I get:

Code: [Select]

#:~/src/sfml2/bindings/c/build$ cmake ..
CMake Error: The following variables are used in this project, but they are set to NOTFOUND.
Please set them or make sure they are set and tested correctly in the CMake files:

It seems to work, when you installed both the release and the debug version of SFML. If you just want a release build, it fails like described.

Using Ubuntu 10.10, x86_64, branches/sfml2 revision 1671

(btw: is this the right place for questions like this? I didn't find an active bug tracker.)

General / Compiling sfml2 with mingw (without Codeblocks)

« on: April 13, 2010, 01:36:03 pm »

Hi!

I am trying to compile the sfml2 svn snapshot with mingw (without Codeblocks on Windows XP). When invoking "make", I get the following error:

Code: [Select]


../../src/SFML/System/Thread.o:C:\msys\1.0\home\Administrator\nikki\playground\sfml\sfml2\build\make/../../src/SFML/System/Thread.cpp:97: undefined reference to `sf::priv::ThreadImpl::~ThreadImpl()'


(and the same for line 85)

My guess is, that this has something to do with the platform-dependent implementation of threads (although this might just be a wild guess).

So my question is this: Is it supported to compile sfml like this? AKA Is this just a temporary failure in svn that will be fixed?

Or should I use Codeblocks to compile sfml2? (From what I understand, using Codeblocks (with the mingw-compiler) is "the SFML-way" (tm) to compile things on windows. So I guess this problem doesn't exist when using Codeblocks.

Thanks for any advice.

Audio / delay in Sound.Play() (Windows XP)

« on: April 09, 2010, 05:57:55 pm »

Hi!

I am using sfml-audio to play some sounds and there seems to be a delay between the call to Sound.Play() and the actual playing of the sound. My estimate is, that the delay is ~250 ms long (but that's of course hard to measure). This problem shows in Windows XP, on a linux system the same code plays sounds without the delay.

When I try to play the sound looped (as suggested in another thread for a similar problem) there is no gap.

Is this a problem with sfml, OpenAL or something else?

Any help appreciated.
