Date: Tue, 01 Jun 2004 15:27:44 +0300 From: Martin_Storsj Subject: Update for dynamic loading of ALSA I sent you a patch a few months ago which enables SDL to load ALSA dynamically. Now I've finally got time to tweak this yet some more. I've added code from alsa.m4 (from alsa's dev package) to acinclude.m4, and made the detection of the alsa library name a bit better. I've also fixed up the loading versioned symbols with dlvsym, so that it falls back to dlsym. I wouldn't say the configure script is complete yet, but this is how far I've come this time, and I'm no expert at those things.
