Description: Child process seg faults on php call
Found a post on a newsgroup that gets around this bug. I modified libtool and it runs
successfully now.
The configure script generates a script named 'libtool'. Modify the archive_cmds= and
archive_expsym_cmds line to include the following switch:
\${wl}-bI:/ias/Apache/Apache/libexec/httpd.exp
This tells PHP which calls to the Apache API have been exported and can be resolved at
runtime.

Here is exactly what I did to reproduce the problem. This is on an AIX 4.3.3 box with
Oracle 9iAS which runs Apache 1.3.12. I have successfully installed PHP on Oracle
8iAS which runs Apache 1.3.9.
Here's the exact steps I took to install PHP:
NOTE: I ran all of this as the oracle user and I had my ORACLE_HOME set to
/ias/6iserver. This shouldn't be necessary since we specify this on the configure
line but I did it to be safe.
Added -I/ias/Apache/perl/lib/5.00503 to the end of the #!perl call at the top of the
apxs script. A perl module (strict.pm) is required but is not found in the include
path when the configure script runs apxs.
Also, I'm not sure why, but Oracle 9iAS automatically assumes everyone is running
Solaris. In the apxs script I changed a '-DSOLARIS2=260' reference to -DAIX=43.
Ran CC=cc configure --with-apxs=/ias/Apache/Apache/bin/apxs --with-oci8=/ias/6iserver
--without-mysql --prefix=/ias/Apache/Apache
After the configure script was done I edited config_vars.mk and added
-I/ias/rdbms/demo and -I/ias/rdbms/public to the INCLUDES variable. IAS keeps some of
the oci8 header files in these directories. Also, for 9i I had to add
-I/ias/Apache/Apache/include to the INCLUDES variable. I did not have to do this for
8iAS.
AIX has a sparsely documented bug where alloca() is not defined on the system and the
PHP configure script does not seem to handle this properly. We need to add -ma to
CFLAGS to get around this.
Created a link in /ias/6iserver/lib for libclntsh.a. For some reason only a .so was
included in 9iAS. I checked 8iAS and this file is not missing here. Ran ln -s
libclntsh.so libclntsh.a in the /ias/6iserver/lib directory.
Ran make.
Ran make install.
Apache starts up ok, but I get a seg fault at the first call to PHP. Only the child
http process dies.
Apache error log shows:
[Sun Feb 18 20:51:19 2001] [notice] Apache/1.3.12 (Unix) ApacheJServ/1.1 PHP/4.0.4pl1

Any ideas?
