mm cache - php bug?


From: Ted Lu
Subject: mm cache - php bug?
Date: Mon, 18 Aug 2003 01:46:15 -0700

Hi,

I use Linux 9.0  with Apache server  version 2.0.47, php version 4.3.3RC3 
installed
ok.
Then I try to install Turck MM Cache version 2.3.22.  While I issued the command

% ./configure --enable-mmcache=shared
--with-php-config=/usr/local/php4/bin/php-config

I got the following message.

=================================================================
configure: WARNING: ext/session/php_session.h: present but cannot be compiled
configure: WARNING: ext/session/php_session.h: check for missing prerequisite
headers?
configure: WARNING: ext/session/php_session.h: proceeding with the 
preprocessor's
result
configure: WARNING:     ## ------------------------------------ ##
configure: WARNING:     ## Report this to address@hidden ##
configure: WARNING:     ## ------------------------------------ ##
===================================================================

I tried to continue and finished but it cannot recognize the 
"extension="mmcache.so"
which is added
inside the php.ini.

The php_session.h is also attached in this email.

Please have a loook.  Thanks!

Ted
