Coincidentally, for a while now I've been using a modified build of pulseaudio that has the whole ltdl_bind_now feature stripped out of it. Why, you might ask? Because without the ltdl_bind_now stuff, pulse 0.9.15-stable can be built with older versions of libtool and libltdl-dev (like the ones in Debian Lenny). I'm not sure quite what the bind_now stuff is trying to achieve. The stated purpose is simple enough, but as far as I can tell pulse isn't doing a bunch of other things that would be needed to avoid all unexpected delays in real-time code (e.g. preloading and locking code pages in RAM, preallocating stack, and so forth). It also seems to me that most of these delays can be avoided by simply executing a complete cycle of the audio processing loop once, and most human observers won't notice even the worst case delays in the first loop iteration (and the humans who do notice can start the PA daemon in advance and/or play some silent preroll samples with the specific sink inputs they intend to use). So I'm all in favor of dropping the feature. If the ltdl_bind_now stuff goes away, can the libtool dependency be downgraded as well? -------------- next part -------------- A non-text attachment was scrubbed...
