how can I get past this ?

configure:2106: checking if compiler supports -R
configure:2121: gcc -o conftest -g -O2 conftest.c -R /usr/lib 1>&5
gcc: unrecognized option `-R'
/usr/lib: file not recognized: Is a directory
collect2: ld returned 1 exit status
configure: failed program was:
#line 2114 "configure"
#include "confdefs.h"

int main() {

; return 0; }

Looks like maybe a dud makefile... but more info needed.

php 4.3.4 configure
the part above is from the config.log

not really sure what other info you need.

From http://us2.php.net/oci8

I installed Oracle 8.1.7 client, mod_php (4.2.2, as DSO) on a RedHat 7.1 (Seawolf) and among others encountered the "cannot find -lclntsh" problem during making. But the already suggested "shared,{$ORACLE_HOME}" solution didnt work for me.
I finally found a solution:

Usually, the linker (ld) complains, that it can't find the clntsh .so / .a files, but they were present (check in the lib dir of $ORACLE_HOME if present, if not execute ../bin/relink as user Oracle and check what the error message says).

As I backtraced the incident, I found in the configure.log file the following lines:

configure: 2842 gcc -o conftest -g -O2 conftest.c -R /usr/lib 1>&5
gcc: unrecognized option '-R'
/usr/lib: file not recognized: Is a directory
collect2: ld returned 1 exit status

It turned out, that in the ./configure script it is checked, wether the compiler supports the -R option.
However, after I commented the lines responsible for this check and told the script, that my compiler wont support "-R" and as well doesnt need to check, after a make clean and ./configure it actually could be compiled.

You can find the lines I commented by searching for the regexp check.*-R. Comment from there till the next "else" and a "fi" a few lines below. Good Luck!
