Hey folks,

I'm trying to configure a Xeon processor-based (EM64T/AMD 64) SuSE 9.2 
Professional machine to run Apache 1.3.33, PHP 5.0.3 and WebSphere 
Application Server 5.1.1.3.   I was able to get all these guys cooperating 
on a 32 bit Pentium III machine on the same version of SuSE Pro.  But I 
seem to be running into some 32 bit vs 64 bit issues on this new machine.

The way things worked out on the older machine was that I had a binary 
installation of Apache (IBM HTTP Server, based on 1.3.28) which used a 
shared object to communicate with WAS, and which used libphp5.so that I 
compiled against it via apxs for PHP.  All was well.

On this machine, however, I can't get the precompiled 32-bit Apache (IHS) 
talking to PHP via libphp5.so, as the PHP build against it creates a 
64-bit object:

# /opt/IBMHttpServer/bin/apachectl configtest
Syntax error on line 231 of /opt/IBMHttpServer/conf/httpd.conf:
Cannot load /opt/IBMHttpServer/libexec/libphp5.so into server: 
/opt/IBMHttpServer/libexec/libphp5.so: cannot open shared object file: No 
such file or directory

# file /opt/IBMHttpServer/libexec/libphp5.so
/opt/IBMHttpServer/libexec/libphp5.so: ELF 64-bit LSB shared object, AMD 
x86-64, version 1 (SYSV), not stripped


On the other hand, if I try to compile my own version of Apache, it will 
work with the 64-bit version of libphp5.so, but will not use the 32-bit 
WebSphere plugin:

# /opt/local/apache/bin/apachectl configtest
Syntax error on line 243 of /opt/local/apache/conf/httpd.conf:
Cannot load /opt/WebSphere/AppServer/bin/mod_ibm_app_server_http.so into 
server: /opt/WebSphere/AppServer/bin/mod_ibm_app_server_http.so: cannot 
open shared object file: No such file or directory

# file /opt/WebSphere/AppServer/bin/mod_ibm_app_server_http.so
/opt/WebSphere/AppServer/bin/mod_ibm_app_server_http.so: ELF 32-bit LSB 
shared object, Intel 80386, version 1 (SYSV), not stripped


So, I guess my question is how can I get my 64-bit version of Apache to 
use the 32-bit WAS plugin, or alternately how can I get the 32-bit version 
of IHS to use the 64-bit PHP object?  Is it possible to do that?  If not, 
how would I compile a 32-bit version of libphp5.so on AMD 64 so that the 
32-bit version of IHS can use it? 

Thanks in advance for any pointers.
