There's really no away around the fact that audio is still a mess on Linux. Best plan is to use either SDL or OpenAL and let that deal with the lowlevel. --ryan. |

My understanding is that OSS still supports some sound cards that ALSA
doesn't, so if you have such a card then OSS is the way to go. If on the
other hand ALSA support is available then that is the preferred way. For
me ALSA has been nice, and the Debian packages makes configuration a
non-issue.

It has become the default API in 2.6 kernels, and is considered the default sound API these days. It provides a backward compatible OSS device emulation, but it's not always enabled at compile time ( and not always working right if you use DMA modes ). Writing directly for ALSA is a better choice I think. TTimo |

Can anyone give me a quick summary of the state of ALSA vs. OSS today? It's my understanding that ALSO is considered more modern but that adoption is slower, hence OSS is a bit more reliably available -- but is that still the case, and if it is, is it even relevant for the fraction of Linux users that play games?

Hi, I have a few programs that are linked against libraries that are placed on the same path as the executable. That works fine I link the executable using '-rpath,.', but only when the program has been executed from the location of the executable. I would like to run the executable from anywhere and had the following idea: create a simple program that changes the current folder and creates another process for the real program, so that the real program starts in the correct location. Does somebody know a better way of doing the same? Thanks in advance, -- Ignacio Castaño cas...@ya... |

Hi,
I've finally found a very simple solution that should work on most cases.
Currently most distributions provide dialog programs, those programs are
designed to be used from shell scripts, and provide a very simple
interface to create different kind of dialogs. Some examples of those
programs are: kdialog, zenity and xdialog.
So, to create a simple message box, you can do:
system( format("kdialog --title %s --msgbox %s", title, text) );
If none of those programs are available, you can still use a little
utility called xmessage that I think should be available on most systems.
Hope that helps,
--

The Mac used to have something called PlainTalk - don't know if it comes with MacOS X. There seem to be numerous commercial packages that will run on Linux, e.g. IBM ViaVoice. On the open-source front, I just read in IEEE Spectrum that Intel released an audio-visual speech recognition library as open-source. It's on sourceforge in the opencvlibrary project as the openAVSR package. Looks like it'll run on windows and linux (x86, I assume). That's probably more than what you're looking for, but I thought it sounded pretty cool. Got a lot of hits for speech libraries on sourceforge, many of them implemented in Java, e.g. FreeTTS (speech synthesis). CMU Sphinx for speech recognition seems like a possibility. Apache-style license and runs on windows, linux and java. -Phil Daniel Vogel wrote: > Does anyone know of libraries providing functionality a la Microsoft's > Speech SDK for Linux and/ or Mac? > > http://www.microsoft.com/speech/download/sdk51/ > > I'm interested in both speech recognition and speech synthesis functionality > as we utilize them for the Windows version of UT2004 and wouldn't mind > having equivalent features for the Mac/Linux version. > > -- Daniel, Epic Games Inc. > > > > ------------------------------------------------------- > This SF.Net email sponsored by: ApacheCon 2003, > 16-19 November in Las Vegas.

Does anyone know of libraries providing functionality a la Microsoft's Speech SDK for Linux and/ or Mac? http://www.microsoft.com/speech/download/sdk51/ I'm interested in both speech recognition and speech synthesis = functionality as we utilize them for the Windows version of UT2004 and wouldn't mind having equivalent features for the Mac/Linux version. -- Daniel, Epic Games Inc. |

You can make a number of large assumptions, and thus make an educated guess, but that's about it. If They're running KDE and Konquerer is installed, then it is minimally not an unlikely choice, but has no guarantees. If they are running Gnome, Gnome has a concept of a default handler for HHTP URLs, and the user has set that preference (frequently not the case), and the browser that the preference points to is even installed (may or may not be true, then that is also a fairly reasonable guess. If they're not running either KDE or Gnome then you really have no idea. Just check the process table to see if you can find a browser being used by the current user, and use that. If that fails, just pick the first recognisable thing you find off $PATH. Or you could just ask the user... -- J C Lawrence ---------(*) Satan, oscillate my metallic sonatas. cl...@ka...

I _think_ I've seen some > sample source code for this, and I know our own apps supports this. Some Unix libraries and applications follow the "BROWSER" environment variable, in the way that "EDITOR" is generally respected as a means to determine the preferred text editor. From python's library reference (since they describe it well enough) ... "Under Unix, if the environment variable BROWSER exists, it is interpreted to override the platform default list of browsers, as a colon-separated list of browsers to try in order. When the value of a list part contains the string %s, then it is interpreted as a literal browser command line to be used with the argument URL substituted for the %s; if the part does not contain %s, it is simply interpreted as the name of the browser to launch." UT2003 does this, but if BROWSER isn't set, we use a default like this: "opera:mozilla:galeon:konqueror:netscape:xterm -e links:xterm -e lynx:"; This is all trial and error, but I tried to organize the defaults in order of what will likely be a preference if it exists on a system at all (i.e. - If opera is installed, it's almost certain the user went out of their way to have it, so try it first. "netscape" generally exists on any modern Linux system if nothing more modern has been added, and "lynx" is a desperate fallback. In more recent times, "galeon" should probably be tried before "mozilla" for the same reason "opera" is at the front of the list.) It's not perfect, but it generally seems to work, and if the user gets a browser they don't prefer by default, they can always set the environment variable to their liking. But there isn't an honest-to-god facility for determining the correct browser. --ryan. |

I don't believe this is possible, you have to do some convoluted searching for the appropriate browser. I _think_ I've seen some sample source code for this, and I know our own apps supports this.

My main concern is that I don't want to distribute the wx libraries (that are >1Mb) with my application. I have been thinking about using gtk, but it might not be available on the target machine either and in that case I would have the same problem. Do you know of a simpler library that just provides a messagebox on top of xlib only? Now that I think about it, in this case fltk could be a better alternative, specially because it can be statically linked. -- Ignacio Castaño cas...@ya... |
