# SYNOPSIS
|
|
#
|
|
# AX_BERKELEY_DB([MINIMUM-VERSION [, ACTION-IF-FOUND [, ACTION-IF-NOT-FOUND]]])
|
|
#
|
|
# DESCRIPTION
|
|
#
|
|
# This macro tries to find Berkeley DB. It honors MINIMUM-VERSION if
|
|
# given.
|
|
#
|
|
# If libdb is found, DB_HEADER and DB_LIBS variables are set and
|
|
# ACTION-IF-FOUND shell code is executed if specified. DB_HEADER is
|
|
# set to location of db.h header in quotes (e.g. "db3/db.h") and
|
|
# AC_DEFINE_UNQUOTED is called on it, so that you can type
|
|
#
|
|
# #include DB_HEADER
|
|
#
|
|
# in your C/C++ code. DB_LIBS is set to linker flags needed to link
|
|
# against the library (e.g. -ldb3.1) and AC_SUBST is called on it.
