   3 # This Makefile fragment is included by package Makefiles and
   4 # buildlink3.mk files for the packages that use dlopen().
   5 #
   6 # It defines the variables DL_CFLAGS, DL_LDFLAGS and DL_LIBS, which
   7 # are also exported into the CONFIGURE_ENV and MAKE_ENV environments.
   8 #
   9 # Package-settable variables:
  10 #
  11 # DL_AUTO_VARS
  12 #       When set to "yes", the necessary flags are added automatically
  13 #       to CFLAGS and friends.
  14 #
  15 #       Default: no

  17 # Keywords: dl dlopen
