After I compile php-4.0.0 with mcrypt support, I could not fire up apache, it give me no error message on apache error log.  however, if I remove --with-mcrypt option, apache fire up ok with php-4.0.0
I tried --disable-posix-threads, but make no different
here is my  compile script on php-4.0.0

./configure \
 --with-apxs=/usr/apps/apache_1.3.12/bin/apxs \
 --with-interbase=/usr/interbase \
 --with-oracle=$ORACLE_HOME \
 --with-oci8=$ORACLE_HOME \
 --with-gdbm \
 --with-dba \
 --with-xml \
 --with-png-dir=/usr/local/lib \
 --with-mcrypt=/usr/local/lib \
 --disable-posix-threads \
 --disable-debug \
 --without-mysql \
 --enable-versioning \
 --enable-track-vars

even I remove --disable-debug, it still give me no error message.

Also, I find oracle very unstable under php-4.0.0, sometime it works, somtime it doesn't with the same code.
<?
      $con = ora_logon ($u, $p);
      $echo "$con";
      ora_close ($con);
?>

cheers,
