#668: problem: fc.11: emacs + eflite does not work. -----------------------------------------+---------------------------------- Reporter: rabbit | Owner: lennart Type: defect | Status: new Milestone: | Component: daemon Keywords: eflite emacspeak flite alsa | -----------------------------------------+---------------------------------- - just to isolate problem, I decided to run emacs+emacspeak+eflite from console.
- there was no problem running the same version of flite/eflite/emacs/emacspeak in fc9. - pulseaudio binary works of course. - problem exists only in (emacs+emacspeak)+(flite+eflite) case. When flite+eflite runs alone from commandline, and reads data let's say from standard input, there is no problem. how to run it to read from stdin? prompt$ ./eflite q {hallo world} d #now You should hear "hallo world". - problem comes from eflite server thread. client keeps on putting data to socket, while server stops on strace: futex(0x454edf54, FUTEX_WAIT_PRIVATE, 43, NULL or more detailed gdb (I noticed 2 cases). gdb: (gdb) bt #1 #0 0x00e91422 in __kernel_vsyscall () #1 0x008c2fa5 in pthread_cond_wait@@GLIBC_2.3.2 () at ../nptl/sysdeps/unix/sysv/linux/i386/i486/pthread_cond_wait.S:122 #2 0x005cb2ed in pa_cond_wait (c=0xb750c988, m=0xb750c930) at pulsecore /mutex-posix.c:139 #3 0x003c1a5e in pa_threaded_mainloop_wait (m=0xb750c838) at pulse /thread-mainloop.c:201 #4 0x00113ae3 in pulse_wait_operation () from /usr/lib/alsa- lib/libasound_module_pcm_pulse.so #5 0x00112d88 in snd_config_iterator_end () at conf.c:3815 #6 0x03e8f7d9 in snd_pcm_ioplug_drop (pcm=0xb750ef20) at pcm_ioplug.c:464 #7 0x03e45281 in snd_pcm_drop (pcm=0xb750ef20) at pcm.c:1091 #8 0x009896f5 in audio_drain_alsa (ad=0xb7508698) at au_alsa.c:299 #9 0x0098a36d in audio_drain (ad=0xb7508698) at audio.c:213 #10 0x0804be5a in s_clear (s=0x80515e0) at fs.c:884 #11 0x0804cda0 in parse (client=0x8e36bd0, buf=0x8e36ce8 "s") at es.c:590 #12 0x0804d197 in handle (client=0x8e36bd0) at es.c:673 #13 0x0804dc3d in main (argc=1, argv=0xbfdbded4) at es.c:910 (gdb) bt #2 #0 0x00ff0422 in __kernel_vsyscall () #1 0x008c6936 in __pause_nocancel () from /lib/libpthread.so.0 #2 0x008c0ba4 in __pthread_mutex_lock_full (mutex=0xb690c930) at pthread_mutex_lock.c:316 #3 0x005cac5a in pa_mutex_lock () from /usr/lib/libpulsecommon-0.9.15.so #4 0x003c1702 in pa_threaded_mainloop_lock () from /usr/lib/libpulse.so.0 #5 0x00112d16 in snd_config_iterator_end () at conf.c:3815 #6 0x03e8f7d9 in snd_pcm_ioplug_drop (pcm=0xb690e480) at pcm_ioplug.c:464 #7 0x03e45281 in snd_pcm_drop (pcm=0xb690e480) at pcm.c:1091 #8 0x03e4b550 in snd_pcm_close (pcm=0xb690e480) at pcm.c:695 #9 0x009899fe in audio_close_alsa (ad=0xb69084e8) at au_alsa.c:193 #10 0x0098a831 in audio_close (ad=0xb69084e8) at audio.c:81 #11 0x0804a119 in close_audiodev () at fs.c:503 #12 0x0804c058 in s_clear (s=0x80515e0) at fs.c:910 #13 0x0804cda0 in parse (client=0x8739bd0, buf=0x8739ce8 "s") at es.c:590 #14 0x0804d197 in handle (client=0x8739bd0) at es.c:673 #15 0x0804dc3d in main (argc=1, argv=0xbf8b3804) at es.c:910 (gdb) To get this trace I used the fact that eflite stops working after some time, so I could attach gdb to running process. some info on software. emacs 23.1.1 compiled by me. emacspeak 30.0 compiled by me. flite-1.3.13.fc11 (built by fedora). eflite 0.4.2 built by me. efltite module taken from CVSROOT=:pserver:anonym...@eflite.cvs.sourceforge.net:/cvsroot/eflite. how to build: autoconf && ./configure --with-audio=alsa && make. Don't forget to install alsa-lib-devel-1.0.21-3.fc11.i586 (/usr/include/sys/asoundlib.h must exist). to run emacspeak with eflite edit /usr/local/bin/emacspeak: ...... ...... # add 2 following lines: DTK_PROGRAM=/path/to/eflite export DTK_PROGRAM EMACS_UNIBYTE=1 export EMACS_UNIBYTE exec emacs -q -l /usr/local/share/emacs/site-lisp/emacspeak/lisp /emacspeak-setup.el $INITSTR $CL_ALL then run /usr/local/bin/emacspeak.
