"shared" PHP build problems on AIX

[Frank Fegert <fra.nospam.nk@xxxxxx>]

Hello all,

i'm currently trying to get a modularized (i.e. "shared") PHP to build
on AIX, but i'm running into some wierd linking issues with php-cli and
php-cgi, which i hope someone here can help me out with.
The environment is:
  AIX: 6100-08-01-1245
  xlC: 11.01.0000.0009
  php: 5.3.26

the relevant configure snippet from the RPM spec file is shown below.
If every "shared" keyword is removed in there, i get a "php", "php-cgi"
and "libphp5.so", each one by itself working like they are supposed to
and with the following number of symbols (via "dump -Tv"):
  php: 7177
  php-cgi: 7201
  libphp5.so: 7236

If i build with the "shared" keyword like shown below, the build is
also successful, but the binaries have the following number of symbols:
  php: 896
  php-cgi: 900
  libphp5.so: 6151

Executing PHP code depending on e.g. the MySQL module via the libphp5.so
in Apache works fine. But running code depending on e.g. the MySQL module
in "php" or "php-cgi" results in errors like this:

  PHP Warning:  PHP Startup: Unable to load dynamic library '/libdir/php/modules/mysql.so' -
  rtld: 0712-001 Symbol OnUpdateLong was referenced
        from module /libdir/php/modules/mysql.so(), but a runtime definition
              of the symbol was not found.
  rtld: 0712-001 Symbol zend_ini_boolean_displayer_cb was referenced
        from module /libdir/php/modules/mysql.so(), but a runtime definition
              of the symbol was not found.
  rtld: 0712-001 Symbol display_link_numbers was referenced
        from module /libdir/php/modules/mysql.so(), but a runtime definition
              of the symbol was not found.
  rtld: 0712-001 Symbol OnUpdateString was referenced
        from module /libdir/php/modules/mysql.so(), but a runtime definition
              of the symbol was not found.
  rtld: 0712-001 Symbol OnUpdateStringUnempty was referenced
        from module /libdir/php/modules/mysql.so(), but a runtime definition
              of the symbol was not found.
  rtld: 0712-001 Symbol zend_parse_parameters was referenc in Unknown on line 0

Does anyone have an idea where to look why php and php-cgi aren't build
like libphp5.so when configured as "shared"?

Thanks & best regards,
