Description:
------------
Cannot successfully compile php-informix when using any of the following Fedora Core 2 srpms:
php-4.3.4-11, php-4.3.6-6, or php-4.3.7-1
As well as the source php-3.4.7 from php.net

I added the " || true" to the makefiles of 4.3.4 and 4.3.6 so they would finish compiling just like 4.3.7 (see recent changelog), but all of them give bad end results.

The only Informix Client SDK's available on IBM's website are 2.81.UC1, 2.81.UC2, and 2.81.UC3.  I tried all three with the same result. 

I set the following env vars:
INFORMIXDIR=/usr/local/informix
LD_LIBRARY_PATH=:/usr/local/informix/lib:/usr/local/informix/lib/esql

I was able to compile perl's DBD::Informix with no problems and I can query and write to my DB, so I think informix sdk is fine.

I add --with-informix=/usr/local/informix to php's SPEC file.  It starts compiling fine, then gives this error:

*******  RPM compile error:
   /usr/bin/ld: cannot find -lphpifx
   collect2: ld returned 1 exit status
   make: *** [sapi/cgi/php] Error 1
   error: Bad exit status from /home/admin/tmp/rpm-tmp.54071 (%build)

***  Strategy 2, forget the whole rpm and just do Informix module  ***

Since I already have php installed, I tried going into the php4.3.x/ext/informix dir to compile this module by itself.  I used the following commands:
phpize
./configure
make

It says it builds completely and without error.
cp modules/informix.so /usr/lib/php4/informix.so
put the appropriate informix.ini in /etc/php.d

then I use the following command to test it:
/home/admin>  php ifxtest.php

ifxtest.php contains the following lines of code:
<?
#ifx_connect(1,2,3);
?>

This script should give an error saying it could not connect to the database because I gave it bogus parameters.  But instead I get:

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