Yes, I was referring to that library and more info could be found from the web: http://www.libsdl.org/. The problem with the boost timer that you mentioned is that it provides

time elapsed, but not the interface like provided by SDL lib. Particularly the kind of timer callback function that is available in SDL lib is not available in Boost lit.

Christian, I was able to extract out SDL timers from the library and wrapped a callback timer class that is used with boost library. I am not sure if there are interests to port that into boost library. Although the SDL timer functions is under LGPL license but we can put the callback timer class under boost library.

Christian, Boost is very widely accepted and utilized by game developers, and on the web GameDev.net there are many many articles about various boost sub lib. But I haven't seen many discussions about SDL lib on this boost mail list from boost users/developers. SDL is very convenient cross-platform C++ development platform that can be used not only game developers but also by other developers. It has easy-to-use classes of multithreads, mutex, event queues, timer callbacks, semaphores, key board input handling, audio, video, to name a few. Most of these functionalities are available from Boost lib. But I haven't seen good timer callback available from Boost lib (anybody can correct me if I am not so informed of Boost timer). I tried to extract the timer functions (classes) from the SDL lib into an individual timer lib, and the work is still in progress. I am not sure other users in the list are interested in knowing about porting SDL timer to Boost. So if you can tell me your email of this email list, I can send you the project file. What exactly I did was that I included the relevant source files from SDL package, and compile it with testing program. I was able to get the exe file but the project also generated a library file in addition to the exe file. I am confused by the fact that the project generating TimerTest.lib, that I don't want t. Rather, I wanted to link them with TimerTest not intended to. I checked the project configuration file, and there is no setting that will generate a library file. I think it might be set in the program source code, but I did not find it. I am interested in your idea of implement SDL wrapper in boost lib. Thank you!

Fanzhe, I have been working on a sdl wrapper for boost::gil. It lets you draw on a canvas and react to event such as a timer event. I was thinking of outsourcing this portion so people can use just that. The good thing is the sdl is supporting almost the same platforms as boost does. The bad thing probably is the license sdl is using, LGPL. If you want I can give you a pointer for the code. Christian On 6/6/07, fanzhe cui wrote: the lib that

there is still no good implementation of timer in Boost lib (correct me if I am wrong). Anybody in this email list had a look at GameDev timer and have considered implementing such a lib in Boost?

Are you referring to the Simple Direct Medialayer?

What's wrong with/missing in boost::timer ?
