AX_LIB_POSTGRESQL([MINIMUM-VERSION],[ACTION-IF-FOUND],[ACTION-IF-NOT-FOUND])
This macro provides tests of availability of PostgreSQL ’libpq’ library of particular version or newer.
AX_LIB_POSTGRESQL macro takes only one argument which is optional. If there is no required version passed, then macro does not run version test.
The –with-postgresql option takes one of three possible values:
no - do not check for PostgreSQL client library
yes - do check for PostgreSQL library in standard locations (pg_config should be in the PATH)
path - complete path to pg_config utility, use this option if pg_config can’t be found in the PATH (You could set also PG_CONFIG variable)
This macro calls:
AC_SUBST(POSTGRESQL_CPPFLAGS) AC_SUBST(POSTGRESQL_LDFLAGS) AC_SUBST(POSTGRESQL_LIBS) AC_SUBST(POSTGRESQL_VERSION)
And sets:
HAVE_POSTGRESQL
It execute if found ACTION-IF-FOUND (empty by default) and ACTION-IF-NOT-FOUND (AC_MSG_FAILURE by default) if not found.
