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