AX_LIB_ORACLE_OCI([MINIMUM-VERSION])
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.
Macro supports following options and their values:
1) Single-option usage:
--with-oci -- path to ORACLE_HOME directory
2) Two-options usage (both options are required):
--with-oci-include -- path to directory with OCI headers
--with-oci-lib -- path to directory with OCI libraries
NOTE: These options described above do not take yes|no values. If 'yes' value is passed, then WARNING message will be displayed, 'no' value, as well as the --without-oci-* variations will cause the macro to not check enything.
This macro calls:
AC_SUBST(ORACLE_OCI_CFLAGS) AC_SUBST(ORACLE_OCI_LDFLAGS) AC_SUBST(ORACLE_OCI_VERSION)
And sets:
