Fatal error: Call to undefined function oci_connect()

I followed one of the documentation realed to this error and I get below error.

environment variable is set correctly and then rerun this script.

I was looking into below link. But I could not find oci8.so file after the OCI build.

===> In reply to my request *"mgogala's"* reply was as below.

Install autoconf using yast. Check whether the package is installed by using:

$>rpm -qa autoconf
autoconf-2.59-5

BTW, this is not a Linux forum. There is one on OTN, I'm sure that Frits Hoogland will gladly help you out.
