[ERROR] PHP4 as Apache DSO Module

Anon

I am trying to install php4 as an apache dso module. Everything works fine upto the point of starting apache. I get this message when starting:

Can't locate API module structure 'php4_module' in file /home/httpd/lib/libphp4.so: /home/httpd/lib/libphp4.so: undefined symbol: php4_module
bin/apachectl start: httpd could not be started

At this current time, I have apache running with mod_ssl, cold fusion and JSERV, all as DSO modules.

It is all running in Linux slackware 7 with kernel 2.2.16 with glibc2

This is the configuration I used for php4:

./configure --prefix=/home/httpd --with-apxs=/home/httpd/bin/apxs --with-xml --with-ftp --with-mysql=/usr/local --with-config-file-path=/home/httpd/conf --disable-debug --enable-track-vars --enable-magic-quotes --with-dom --with-servlet=/usr/local/jsdk --with-java=/usr/local/jdk --disable-short-tags --enable-calendar --with-openssl

Again, the configure, make and make install all work, the error happens when trying to load the module into apache.

This is how I configured apache:

SSL_BASE=/usr/local/ssl CFLAGS="-funroll-loops -02 -finline-functions" ./configure --prefix=/home/httpd --enable-module=so --add-module=src/modules/standard/mod_usertrack.c --enable-module=rewrite --enable-module=ssl --enable-module=log_referer --enable-module=vhost_alias --enable-module=mmap_static --enable-module=log_agent --disable-module=imap

Is the libphp4.so module in the directory? I used apxs and had a similar error. When I checked the directory that the lib module was supposed to be under I found it was not even loaded there. I found it lurking in the /usr/lib directory and copied it to the directory where Apache was looking for it and all went to working. You may also need to edit the Apache conf. file and add the php module as I did not see it in your list.

My httpd.conf file reads 'LoadModule php4_module lib/libphp4.so'

The file is in /home/httpd/lib where it should be. Just to make sure I wasnt stupid, I copied it to /home/httpd/libexec with all the other modules, corrected the httpd.conf to point there and still the same error.

Did the AddModlue mod_php4.c line also get into your httpd.conf file? If so you may just need to rebuild and try again. Sounds like it should be working.

Hello,
your problem comes from servlet that you specify with the option "--with-servlet".

Indeed, you don't access php pages via apache but via your servlet runner. So you don't have to install the LoadModule line. You have to install the servlet runner with the php servlet like it is indicated in php-4.0.2/sapi/servlet/README :
configure your classpath by adding to it phpservlet.ar
configure your LD_RUN_CONFIG with the libphp4.so (it's in /usr/local/lib/php/lib)

If you still have problem, tell me, I'm writing a guideline for that, I will give you the URL.

Bye

What are you talking about? You do indeed access php pages from apache (if that is in fact what you want to do), with the php apache module. The option, --with-servlet, AFIAK, simply builds a Java servlet which runs php scripts. This can then be used in Tomcat or some other engine if you want to interpret PHP pages from a servlet engine. This is the exact reverse of the PHP Java support (running Java code from PHP module), and is entirely orthogonal to getting PHP/Apache running.

In fact, I had Apache/PHP running with Java support (must have been version 4.0.2. It was not working correctly (I believe a deficiency in the premature Java support), so I downloaded PHP 4.0.4 to give it a spin, and I am getting the identical error. I don't know why php4_module symbol would not be defined in libphp4.so. I have tried both with and without the --with-servlet option (this should be irrelevant anyway).

Hi!!!

  I am trying to install php4.0.6 as an apache dso module. Everything works
  fine upto the point of starting apache. I get this message when
  starting: 

  Can't locate API module structure 'php4_module' in file
  /home/httpd/lib/libphp4.so: /home/httpd/lib/libphp4.so: undefined
   symbol: php4_module  bin/apachectl start: httpd could not be started 


  It is all running in Linux Redhat 7.0, Apache 1.3.19 

   This is the configuration I used for php4: 

    ./configure --with-apxs=path_apxs --with-xml=path_xml                 --with-informix=shared,/path_informix --with-gd=path_gd
     --with-mysql=no


   Again, the configure, make and make install all work, the error happens
    when trying to load the module into apache. 


    I was trying, many times but finally got the same error.... I don't know  what to do...  

      Thanks for your Help !!!!

(Sorry for my english..)

Check to see if the module libphp4.so actually loaded into your "/home/httpd/lib/libphp4.so" (that is usually not the base lib directory but it will work if the module is there) directory then check your apache config file to be sure php4 module is installed and is not remarked out (Red Hat puts this in the module but remarks it out by default).
