# SYNOPSIS
|
|
#
|
|
# AX_LIB_ORACLE_OCI([MINIMUM-VERSION])
|
|
#
|
|
# DESCRIPTION
|
|
#
|
|
# 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-oracle -- path to ORACLE_HOME directory
|
|
#
|
|
# 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
|
|
#
|
|
# 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-oracle-* variations will cause the macro to not
|
|
# check anything.
|
|
#
|
|
# This macro calls:
|
|
#
|
|
# AC_SUBST(ORACLE_OCI_CFLAGS)
|
|
# AC_SUBST(ORACLE_OCI_LDFLAGS)
|
|
# AC_SUBST(ORACLE_OCI_LIBS)
|
|
# AC_SUBST(ORACLE_OCI_VERSION)
|
|
#
|
|
# And sets:
|
|
#
|
|
# HAVE_ORACLE_OCI
