   1 # Set the proper macros based on whether we are making the debugging version
   2 # or not.  The valid parameters to this file are:
   3 #
   4 #       DEBUG=1         ==> enable the making of the DBUG version
   5 #       DBMALLOC=1      ==> enable DBUG version with extensive MALLOC checking
   6 #
   7 #       DB_CFLAGS       ==> CFLAGS is set to this value at the end if DEBUG=1
   8 #       DB_LDFLAGS      ==> LDFLAGS is set to this at the end if DEBUG=1
   9 #       DB_LDLIBS       ==> LDLIBS is set to this at end if DEBUG=1
  10 #
  11 # The non debug versions of the above three macros are:
  12 #
  13 #       NDB_CFLAGS
  14 #       NDB_LDFLAGS
  15 #       NDB_LDLIBS
  16 #
  17 # One of the set of three should have values set appropriately prior to
  18 # sourcing this file.
