Re: Linking issues on Solaris 10 x86

[Kristof Van Damme <kristof@xxxxxxx>]

Hi Chris,
Thanks for your answer.

The OCI8 linking problem is a dynamic linking problem and occurs at runtime:
the path to instantclient lib 'libnnz10.so' is not linked in the oci8.so
module, while this is done for the 'libclntsh.so'. So at runtime the
libnnz10.so cannot be found.

This is what we get, when not tweaking the Makefile:

# /opt/app/damp/php/bin/php
PHP Warning:  PHP Startup: Unable to load dynamic library
'/opt/app/damp/php/lib/php/extensions/no-debug-zts-20060613/oci8.so' -
ld.so.1: php: fatal: libnnz10.so: open failed: No such file or directory in
Unknown on line 0

And when listing the dynamic dependencies of the oci8.so I get this output:
# ldd oci8.so 
    libclntsh.so.10.1 =>
/opt/app/damp/instantclient_10_2/libclntsh.so.10.1
    libnnz10.so =>     (file not found)
    ....

When I tweak the makefile and recompile it I get this output for
# ldd oci8.s0
    libclntsh.so.10.1 =>
/opt/app/damp/instantclient_10_2/libclntsh.so.10.1
    libnnz10.so =>     /opt/app/damp/instantclient_10_2/libnnz10.so
    ....
And php can be started at the cli without any problems (all libs found).
This is how it should be in my opinion.

There is a "solution" at the Oracle website, but I don't like it at all.
See http://www.oracle.com/technology/pub/notes/technote_php_instant.html
Here they propose to edit the LD_LIBRARY_PATH of the apache server. It was
written for linux, so it seems that they face the same problem.
IMHO editing LD_LIBRARY_PATH should be avoided if possible (see
http://blogs.sun.com/ali/entry/avoiding_ld_library_path_the). It is much
cleaner to link in the runtime path to the library as is already done for
the libclntsh.so.

I've already tried using the latest OCI8 PECL (version 1.4.1) module, but I
encounter the same problem.
I haven't tried it with instantclient_11_2 yet, but we still use oracle 10.

Regards,
Kristof.
