Where is libclntsh.so and does it have 10.1 suffix?

Assigned to the maintainer.
You can put the libraries to /usr/lib/oracle/10.2.0.3/client/lib/ for now, it should help.

Have make link for all .so into directory lib make link lib32,lib64 to lib but doesn't help so much.

the only thing that really help is putting a PDO_OCI_VERSION=10.2 at line 71961 of .configure and every thing compile correctly after that.

something is wrong in this block of configure's code

 echo $ac_n "checking Oracle version""... $ac_c" 1>&6
echo "configure:71938: checking Oracle version" >&5
  if test -s "$PDO_OCI_DIR/orainst/unix.rgs"; then
    PDO_OCI_VERSION=`grep '"ocommon"' $PDO_OCI_DIR/orainst/unix.rgs | sed 's/  */:/g' | cut -d: -f 6 | cut -c 2-4`
    test -z "$PDO_OCI_VERSION" && PDO_OCI_VERSION=7.3
  elif test -f $PDO_OCI_LIB_DIR/libclntsh.$SHLIB_SUFFIX_NAME.10.1; then
    PDO_OCI_VERSION=10.1
  elif test -f $PDO_OCI_LIB_DIR/libclntsh.$SHLIB_SUFFIX_NAME.9.0; then
    PDO_OCI_VERSION=9.0
  elif test -f $PDO_OCI_LIB_DIR/libclntsh.$SHLIB_SUFFIX_NAME.8.0; then
    PDO_OCI_VERSION=8.1
  elif test -f $PDO_OCI_LIB_DIR/libclntsh.$SHLIB_SUFFIX_NAME.1.0; then
    PDO_OCI_VERSION=8.0
  elif test -f $PDO_OCI_LIB_DIR/libclntsh.a; then
    if test -f $PDO_OCI_LIB_DIR/libcore4.a; then
      PDO_OCI_VERSION=8.0
    else
      PDO_OCI_VERSION=8.1
    fi
  else
    { echo "configure: error: Oracle-OCI needed libraries not found under $PDO_OCI_DIR" 1>&2; exit 1; }
  fi
  echo "$ac_t""$PDO_OCI_VERSION" 1>&6

  fi

But what I can't find where ...

Did you try using this syntax: --with-pdo-oci=instantclient,/usr,10.2.0.3 ?

Ok find a solution that's not a craky hack

Before ./configure 
# For Oracle client
export LD_LIBRARY_PATH=/usr/lib/oracle/10.2.0.3/client:$LD_LIBRARY_PATH
export ORACLE_HOME=/usr/lib/oracle/10.2.0.3/client

configure option for oracle :
 --with-oci8=shared,instantclient,$ORACLE_HOME,10.2.0.3 \
 --with-pdo-oci=shared,instantclient,$ORACLE_HOME,10.2.0.3 \

And everything goes nicely ... 

I think this trick should be added somewhere in the php website doc for the oci and pdo_oci compilation.
Or/And in the configure --help 

Good work guys as always :-))
If someone could confirm this recette, we can close the bug.

Well, that's exactly what ./configure --help says:
  --with-pdo-oci=DIR      PDO: Oracle-OCI support. Default DIR is ORACLE_HOME.
                            You may also use --with-pdo-oci=instantclient,prefix,version to use
                            the InstantClient SDK. For Linux with 10.1.0.3 rpms (for example) use:
                            --with-pdo-oci=instantclient,/usr,10.1.0.3

Thank tony, I think i shouldn't try to compile somewhere in the middle of the night, 
I've replace the last , by / and that's why it doesn't work.

So now closing this.
