Subject: Dynamic loading of ALSA
I recently discovered that SDL can dynamically load ESD and aRts, and
made a patch which adds this same functionality to ALSA.
The update for configure.in isn't too good (it should e.g. look for
libasound.so in other directories than /usr/lib), because I'm not too
good at shellscripting and autoconf.
The reason for using dlfcn.h and dlopen instead of SDL_LoadLibrary and
SDL_LoadFunction is that libasound uses versioned symbols, and it is
necessary to load the correct version using dlvsym. This isn't probably
any real portability issue, because ALSA is linux-only.

This is the porting of 1.2.0 version of SDL (the latest stable one) to AmigaOS/68k. All the bugs known of the past version have been corrected. And I've added all the new SDL features. This version of SDL needs Cybergraphx V3 (r69+) or CyberGraphX V4 and AHI v3+. Probably it works also with P96 or CGXAga, but it's untested. This version is available as linked library for SAS/C and GCC, only 68k this time, a powerup (ppcemu compatible) and a morphos version will be ready quite soon (i hope). Implemented: - 8/16/24/32bit video modes, both fullscreen and windowed. - Hardware surfaces. - CGX blitting acceleration. - CGX colorkey blitting acceleration. - AHI audio (8/16 bit, with any audio format), always uses unit 0 for now. - Thread support (maybe not 100% compatible with other implementations) - Semaphores - Window resizing and backdrop windows (NEW) - Joystick/Joypad support. To do: - CDRom audio playing support - OpenGL (A guy was working on it but I've lost his tracks :( ) The SAS/C library is distributed with debug info attached, to strip debug info simply add STRIPDEBUG argument to the linker. NOTE: SDL includes debug output using kprintf, to disable it add to your project a function like this: void kprintf(char *a,...) { } Otherwise you can redirect the debug to a console window with sushi, sashimi or similar tools (the default output is the internal serial port). For info, support, bugfix and other feel free to mail me: Gabriele Greco (gabriele.greco@aruba.it) You can find also a small SDL Amiga page at: http://ggreco.interfree.it/sdl.html
