[fpc-pascal] Is TEventobject obsolete?
Hi all, I have a doubt about Basicevent and RTLevent, according to the documentation Basicevent is obsolete and I should use RTLevent instead. I use most of the time Rtlevent but now I need to know the result of WaitFor (signaled, timeout, ect). Rtlevent don't provide this, instead TEventobject in syncobjs does it. The problem is that TEventobject is based on Basicevent, at least in fpc 2.6.1. This means that TEventobject is obsolete also? What should I do to have Events with return result in Wait calls? Thank you in advance and sorry for my poor english. Regards. -- Victor Campillo ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal

[fpc-pascal] Unit initialization in dll initialization for arm/WinCE
Hello all, Does unit initialization in libraries (.dll files) work in arm/WinCE? Somehow it seems that even code placed in the library initialization begin end block isn't executed either. I found some bug reports (e.g. 0019404) suggesting that this didn't work for arm/Linux but it has been added to the trunk. But not for arm/WinCE? If this is the case, is there a feasible workaround to call unit initialization sections manually? I am not statically linking the libraries by means of "external" clauses but I am using LoadLibrary() and GetProcAddress() to communicate with the dll from the exe, so I could create an exported function in the dll and call it manually from the exe after loading if I could somehow iterate in it the unit initialization sections and call them. Thank you in advance. Constantine. ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal

I found some bug reports (e.g. 0019404) suggesting that this didn't work for arm/Linux but it has been added to the trunk. But not for arm/WinCE? Linux and Windows have different schemes for library initialization, so even if it was the case that arm-wince did not work it would not help to apply the fix for arm-linux there as well.

[fpc-pascal] Re: Playing sounds with standard components
I took a look in Openal examples. I need to confess that I expected
something easier. Perhaps, something like:
PlaySound('file.wav', 0)
In MMSystem, we have something like that, but it's not cross platform.
The examples present hundreds of lines. It's something frightful!
Regarding the complexity, probably is's possible to do much more than
simply play a sound. In spite of that, it would be intersting to have
something easier.
The examples work with complex and for me, abstract structures. Which
kind of content, do I need to study to understand Openal or SDL?

On the lazarus forum, kpjcomp made a wrapper for Openal. Haven't tested it
but his example code is as simple as:
openAl := TLazOpenAL.Create;
wav1 := TLazOpenALWavFileSource.Create('drumloop.wav');
wav1.looping := true;
openal.SourceList.Add(wav1);
wav2 := TLazOpenALWavFileSource.Create('chimes.wav');
openal.SourceList.Add(wav2);
wav1.play;
wav2.play;
Perhaps worth looking at.

You need to wrap OpenAL a little to get something so simple.
In my Castle Game Engine (http://castle-engine.sourceforge.net/), I have
SoundEngine wrapper, with which you can play sound like
Buffer := SoundEngine.LoadBuffer(FileName);
SoundEngine.PlaySound(Buffer, false, ...);
See working example in SVN on
http://svn.code.sf.net/p/castle-engine/code/trunk/castle_game_engine/examples/audio/alplay.lpr
You may want to look at the source (LGPL) to see how it's done :)

Hello Ludo. :)
Where do I find the openal_nt unit?
unit1.pas(9,3) Fatal: Can not find unit openal_nt used by Unit1.

Nice project. :)
castle_game_engine-3.0.0-src.zip = +-70MB.
Hm... you could send only the files to play audio? :/
