Description:
------------
Configure reqests the shared OCI library libclntsh.so. The Oracle instant client for AIX (10.1 as well as 10.2) is shipped with libclntsh.a which is supposed to be a shared library(according to Oracle support).

I opened a SR at Oracle because I expect them to ship libclntsh.so. 

Oracle asked to report a bug at PHP also. They say PHP should link libclntsh.a on AIX.

Oracle Reference: SR number 6037776.993 

Reproduce code:
---------------
configure --with-apxs2=/usr/local/apache2/bin/apxs --disable-cli --without-mysql --with-oci8-instant-client=/usr/local/instantclient10_1

Expected result:
----------------
Configure running successfully

Actual result:
--------------
...
checking for Oracle (OCI8) support using ORACLE_HOME installation... no
checking for Oracle (OCI8) support using Oracle Instant Client... yes
checking Oracle Instant Client directory... /usr/local/instantclient10_1

Use OCI8 from PECL.

Soory, I posted a wrong Orcale SR number. The correct one is 6032016.994

Background information: Originally all AIX shared libraries had .a extensions.  Recently AIX supports both .a and .so extensions to mean shared.

Will try OCI8 from PECL. Due to holidays I will probably not find the time until Jan. 15.
 [2007-01-11 10:10 UTC] Martin dot Schnoy at hydro dot com 
I replaced the oci8 extension that was shipped with PHP 4.4.4 by the latest version from PECL, ran buildconf --force and called configure with parameter --with-oci8=instantclient,/usr/local/instantclient10_1. The result was the same as with the originally shipped oci8:

checking for Oracle (OCI8) support... yes
checking Oracle Instant Client directory... /usr/local/instantclient10_1
checking Oracle Instant Client SDK header directory... /usr/local/instantclient1
0_1/sdk/include
checking Oracle Instant Client version... configure: error: Oracle Instant Clien
t library version not supported

Configure failes because it does not find /usr/local/instantclient10_1/libclntsh.so.10.1

>Configure failes because it does not find
>/usr/local/instantclient10_1/libclntsh.so.10.1

ln -s /usr/local/instantclient10_1/libclntsh.so /usr/local/instantclient10_1/libclntsh.so.10.1
 [2007-01-11 10:31 UTC] Martin dot Schnoy at hydro dot com 
There is no /usr/local/instantclient10_1/libclntsh.so, only a /usr/local/instantclient10_1/libclntsh.a. Orcale does not ship libclntsh.so with instant client for AIX.
 [2007-01-11 10:53 UTC] tony2001@php.net 
Then create both .so and .so.10.1 as symlinks to .a.
 [2007-01-11 11:08 UTC] Martin dot Schnoy at hydro dot com 
I tried that already last December. Here is an extract of my posting to Orcale SR 6032016.994:

I linked libclntsh.a as libclntsh.so and 
libclntsh.so.10.1 and compiled PHP 4.4.4. There were no errors at compile time. 
However, there was an error when Apache 2 tried to load the PHP module:

httpd: Syntax error on line 53 of /usr/local/apache2/conf/httpd.conf: 
Cannot load /usr/local/apache2/modules/libphp4.so into server: 

rtld: 0712-001 Symbol OCIInitialize was referenced from module

0509-021 Additional errors occurred but are not reported.

This is because libclntsh.a is in fact no shared library. It is a static 
library that can not be used as a shared library.

Works just fine on AIX, Solaris and other weird OSes using the way I've described. Fix your linker or ask Oracle to provide dynamic libraries instead.
 [2007-01-12 11:37 UTC] Martin dot Schnoy at hydro dot com 
Oracle accepted this issue as bug #5722859 and will distribute the .so in further releases.
