Dear all I've come out with a howto that I wish to contribute back to the community. This howto is actually a sort of a draft that I made for my own "self-reminder". It was an interesting experience collating the data to eventually come out with the stuffs. I hope it is useful enough to someone not to go through the same "hell/happy hunting grounds" The said howto is here - http://www.maulvi.net/2007/06/12/php-with-informix-ids-support-via-ifx-module-centos5-rhel5/ Lastly, I read with interest on comments from Karanbir on building the RPMs. Not sure how to build it myself, I'm still learning. Furthermore, not sure whether IBM would allow their ClientSDK and the PHP module be RPMed, license-wise. Comments, constructive please.. Sincere regards and thanks Maulvi Bakar
