Howdy Miller, Following up from the dev list last year, I added your multi instance test to the c samples included with libpd: https://github.com/libpd/libpd/tree/master/samples/c_samples/multi <https://github.com/libpd/libpd/tree/master/samples/c_samples/multi>
The one thing I want to double check is the changes to z_libpd.c you mentioned in http://lists.puredata.info/pipermail/pd-dev/2014-05/019832.html: <http://lists.puredata.info/pipermail/pd-dev/2014-05/019832.html:> > Here's how I modified libpd_wrapper/z_libpd.c: > > 55d54 > < sys_time = 0; > 110c109 > < sched_tick(sys_time + sys_time_per_dsp_tick); > --- > > > sched_tick(); > > 130c129 > < sched_tick(sys_time + sys_time_per_dsp_tick); \ > --- > > > sched_tick(); \ Currently, that line is https://github.com/libpd/libpd/blob/master/libpd_wrapper/z_libpd.c#L171 <https://github.com/libpd/libpd/blob/master/libpd_wrapper/z_libpd.c#L171> and I’m getting a segfault if I replace it with sched_tick(); AND set gcc optimization to -O3 Here’s a gdb backtrace: #0 0x0000000100091f2f in outlet_float (x=0x3f7ffc2a3f7ffc38, f=0.999937057) at m_obj.c:388 #1 0x00000001000ac572 in pdfloat_bang (x=0x10021ac20) at x_connective.c:89 #2 0x0000000100093d58 in pd_bang (x=0x10021ac20) at m_pd.c:267 #3 0x0000000100091ddd in outlet_bang (x=0x10021ae20) at m_obj.c:363 #4 0x00000001000c45e4 in metro_tick (x=0x10021ada0) at x_time.c:162 #5 0x0000000100095021 in sched_tick () at m_sched.c:418 #6 0x00000001000c5d4d in libpd_process_float (ticks=1, inBuffer=0x7fff5fbffa50, outBuffer=0x7fff5fbff750) at z_libpd.c:173 #7 0x0000000100000d18 in main () If I don’t optimize, it works fine: print: 0 1003-frequency: bang print: 0 1004-frequency: bang 1003-frequency: 1 1004-frequency: 2 1.000000 1.000000 0.999999 0.999999 0.999998 0.999998 0.999997 0.999997 1.000000 1.000000 0.999998 0.999998 0.999996 0.999996 0.999995 0.999995 print: 1 0.999944 0.999944 0.999943 0.999943 0.999942 0.999942 0.999941 0.999941 print: 1 0.999815 0.999815 0.999810 0.999810 0.999804 0.999804 0.999799 0.999799 print: 2 print: 2 -------- Dan Wilcox @danomatika danomatika.com <http://danomatika.com/> robotcowboy.com <http://robotcowboy.com/> > On Apr 21, 2015, at 10:56 AM, Kjetil Matheussen <[email protected]> > wrote: > > But for libpd, are you sure you need to add anything?
