/usr/local/apache/bin/httpsd
Syntax error on line 241 of /usr/local/apache/conf/httpd.conf:
Cannot load /usr/local/apache/libexec/libphp4.so into server: undefined symbol:
bc_compare
Excerpt from php compile time configuration:
--enable-bcmath=shared
Problem:
in Zend/zend_operators.c, function zendi_smart_strcmp(),
there is an unconditional call to bc_compare when bcmath is built, not taking care of
the fact that if the bcmath extension is built as a dso it may be possibly not loaded.
Please note:
DSOs are very helpful if you do one standard build for a variety of servers and
configurations so doing a non-shared build is not a solution.
