Description:
------------
I compile with rpmbuild -bb php.spec

Version csdk: 2.90 UC3
Apache Version: Apache/2.0.52 (Red Hat)

Compilation from sources is ok, but when apache2 restart, the log shows:

PHP Warning:  Unknown(): Unable to load dynamic library '/usr/lib/php4/informix.so' - /opt/informix/lib/esql/libifos.so: undefined symbol: ifx_checkAPI in Unknown on line 0

I try to compile only the informix module with:

phpize (in ext/informix)
./configure
make

compile ok

and copy informix.so to /usr/lib/php4

Restart apache and same problem
