I have installed oracle 8.1.6.
It work fine

when I compile the php-4.0.0

./configure --with-oracle --with-oci8 ......

It's OK, no error ($ORACLE_HOME was set)

then make,make install

at apache directory: (apache 1.3.12)
./configure --activate-module=.....

It's OK too.

BUT

In browser;
these functions ,"ora_plogin,ocilogin"always return 
"Call to undefined function ..."

why?

my "ldconfig -v":
