Offhand, it appears that your header files don't define `struct exception'. Grep through /usr/include/**/*.h, find where `struct exception' is defined, include that, and see if it fixes your problem. Alternatively, try undefining HAVE_MATHERR and see if that helps you. Either way, you should investigate and see why XEmacs configuration system did the wrong thing with HAVE_MATHERR (`config.log' is a good place to start checking.) That's not quite the final solution. There is probably a bug in: 1) XEmacs floating point code; 2) XEmacs configuration mechanism; 3) MkLinux libc headers. IMHO, the culprit is, in order of decreasing probability, #2, #3 or #1. -- Hrvoje Niksic <hniksic(a)srce.hr&gt; | Student at FER Zagreb, Croatia --------------------------------+-------------------------------- HOW YOU CAN TELL THAT IT'S GOING TO BE A ROTTEN DAY: #15 Your pet rock snaps at you.
