Native +audio does not work with recent versions of HP-UX. + +Under HP-UX 10.20 and later (e.g., HP-UX 11.XX), with native audio +enabled, the dumped XEmacs binary ("xemacs") core dumps at startup if +recent versions of the libAlib.sl audio shared library is used. Note +that "temacs" will run, but "xemacs" will dump core. This, of course, +causes the XEmacs build to fail. If GNU malloc is enabled, a stack +trace will show XEmacs to have crashed in the "first" call to malloc(). + +This bug currently exists in all versions of XEmacs, when the undump +mechanism is used. It is not known if using the experimental portable +dumper will allow native audio to work. + +**** Cause: + +Recent versions of the HP-UX 10.20 (and later) audio shared library (in +/opt/audio/lib), pulls in the libdce shared library, which pulls in a +thread (libcma) library. This prevents the HP-UX undump() routine (in +unexhp9k800.c) from properly working. What's happening is that some +initialization routines are being called in the libcma library, *BEFORE* +main() is called, and these initialization routines are calling +malloc(). Unfortunately, in order for the undumper to work, XEmacs must +adjust (move upwards) the sbrk() value *BEFORE* the first call to +malloc(); if malloc() is called before XEmacs has properly adjusted sbrk +(which is what is happening), dumped memory that is being used by +XEmacs, is improperly re-allocated for use by malloc() and the dumped +memory is corrupted. This causes XEmacs to die an horrible death. + +It is believed that versions of the audio library past December 1998 +will trigger this problem. Under HP-UX 10.20, you probably have to +install audio library patches to encounter this. It's probable that +recent "fresh, out-of-the-box" HP-UX 11.XX workstations also have this +problem. For HP-UX 10.20, it's believed that audio patch PHSS_17121 (or +a superceeding one, like PHSS_17554, PHSS_17971, PHSS_18777, PHSS_21481, +or PHSS_21662, etc.) will trigger this. + +To check if your audio library will cause problems for XEmacs, run +"chatr /opt/audio/lib/libAlib.sl". If "libdce" appears in the displayed +shared library list, XEmacs will probably encounter problems if audio is +enabled. + +**** Workaround: + +Don't enable native audio. Re-run configure without native audio +support. + +If your site supports it, try using NAS (Network Audio Support). + +Try using the experimental portable dumper.
