<code>AX_LIB_ORACLE_OCI([MINIMUM-VERSION])</code>
</p>
<h2>
Description
</h2>
<div class="indent">
<p>
This macro provides tests of availability of Oracle OCI API of particular
version or newer. This macros checks for Oracle OCI headers and libraries
and defines compilation flags
</p>
<p>
Macro supports following options and their values:
</p>
<p>
1) Single-option usage: --with-oracle - path to ORACLE_HOME directory
</p>
<p>
2) Two-options usage (both options are required): --with-oracle-include -
path to directory with OCI headers --with-oracle-lib - path to directory
with OCI libraries
</p>
<p>
This macro calls:
</p>
<pre>
AC_SUBST(ORACLE_OCI_CFLAGS)
AC_SUBST(ORACLE_OCI_LDFLAGS)
AC_SUBST(ORACLE_OCI_VERSION)
</pre>
<p>
And sets:
</p>
<pre>
HAVE_ORACLE
</pre>
