<br> uh, i think i made i mistake;<br> <br> i enabled all options during configuration, which probably means that the last one enabled was the overriding one (oss), i did something like<br> <br> ./configure --enable-jack --enable-alsa --enable-oss<br> <br> i thought the 3 options were compatible on a single buy, but maybe one needs to build a separate stk library for each api?<br><br><b><i>"Gary P.

My guess wrt to the error below is the same issue I <br>reported yesterday ... please see the archives. To repeat:<br><br>In RtAudio, search for "pthread_attr_setschedpolicy(&attr, <br>SCHED_RR);" and change the SCHED_RR to
SCHED_OTHER. Make sure you <br>are in the RtApiAlsa section of the code.<br><br>I don't know why this is a problem for some and not others but I will <br>likely make this change in the next release of RtAudio.<br><br>Also, you shouldn't get this error if you are using the Jack API. <br>And RtAudio should use the Jack API automatically if it is only <br>compiled with Jack support. In fact, even if there is multiple Linux <br>audio API support compiled in, Jack gets highest priority. So, if <br>RtAudio finds a running Jack server when it starts up, it uses that.<br><br>Regards,<br><br>--gary<br><br>On 9-Feb-06, at 9:45 PM, Charlls Quarra wrote:<br><br>><br>> Hi,<br>><br>> compiling the following example:<br>> http://ccrma.stanford.edu/software/stk/crealtime.html<br>><br>> with<br>> g++ -D__LINUX_JACK__ crtsine.cpp -o crtsine -lpthread -ljack - <br>> lasound -lstk<br>><br>> ah, btw, i created an ebuild script for stk-4.2.1 for gentooers, is
