PHP_CHECK_FUNC and shared extension (OCI8)

Hi,

how do I use PHP_CHECK_FUNC to make it work even when the extension is
shared?

In ext/oci8/config.m4, if I use

  PHP_ADD_LIBPATH($OCI8_DIR/lib, OCI8_SHARED_LIBADD)
  PHP_CHECK_FUNC(OCILobIsTemporary, clntsh, ocijdbc8)

it works when configured --with-oci8, but not with --with-oci8=shared.
With --with-oci8=shared, the test case in configure does not give
-L$OCI8_DIR/lib to gcc, so it cannot work.

My previous approach:

  AC_SEARCH_LIBS(OCILobIsTemporary, ocijdbc8, [
    PHP_ADD_LIBRARY(ocijdbc8, 1, OCI8_SHARED_LIBADD)
  ], [ ], -lclntsh)
      
suffers from the same problem.

Apparently, I'm something missing here.


FWIW, I append a patch for current 4.3.2-dev, although I have not been
able to test it on anything else then Linux with Oracle 8.1.6. The patch
should not affect those systems that find OCILobIsTemporary with
-lclntsh alone. --with-oci8=shared should be no problem there, although
the configure messages

  checking for OCILobIsTemporary in -lclntsh... no
  checking for __OCILobIsTemporary in -lclntsh... no
  checking for OCILobIsTemporary in -locijdbc8... no
  checking for __OCILobIsTemporary in -locijdbc8... no

are misleading. On Tru64 (where OCILobIsTemporary needs -locijdbc8), it
should work --with-oci8, but still not --with-oci8=shared.

In case somebody wants to test the patch, I put a bzip'ed configure
(built with autoconf 2.13, automake 1.5, libtool 1.4.3) on
<http://elmicha.de/tools/configure.bz2>.
