Problem with Calendar

Hello ! Hope this the right place to ask my question. I have upgraded my RH 5.2 with new GLIBC and all other stuff including PHP 3.0.11 Everything works fine except one thing - attempt to execute dl("/www/bin/calendar.so") causes adding a new record to Apache's error_log: '[notice] child pid nnn exit signal Illegal instruction (4)' Unfortunately, I can't trace the source of this problem :-( So, I decided to make calendar object files along with others during compilation of mod_php. I have added it to makefile.in (FUNCTIONS) and run configure. It compiles Ok and I can see it in library file, but attempt to call one of calendar's functions causes 'call to undefined function' error. So, what should I do to put calendar's functions into mod_php ? TIA -- Dim Zegebart Moscow, Russia
