   3 # Generate crunched binaries using crunchgen(1).
   4 #
   5 # General notes:
   6 #
   7 # A number of Make variables are used to generate the crunchgen config file.
   8 #
   9 #  CRUNCH_SRCDIRS: lists directories to search for included programs
  10 #  CRUNCH_PROGS:  lists programs to be included
  11 #  CRUNCH_LIBS:  libraries to statically link with
  12 #  CRUNCH_SHLIBS:  libraries to dynamically link with
  13 #  CRUNCH_BUILDOPTS: generic build options to be added to every program
  14 #  CRUNCH_BUILDTOOLS: lists programs that need build tools built in the
  15 #       local architecture.
  16 #
  17 # Special options can be specified for individual programs
  18 #  CRUNCH_SRCDIR_${P}: base source directory for program ${P}
  19 #  CRUNCH_BUILDOPTS_${P}: additional build options for ${P}
  20 #  CRUNCH_ALIAS_${P}: additional names to be used for ${P}
  21 #
  22 # By default, any name appearing in CRUNCH_PROGS or CRUNCH_ALIAS_${P}
  23 # will be used to generate a hard link to the resulting binary.
  24 # Specific links can be suppressed by setting
  25 # CRUNCH_SUPPRESS_LINK_${NAME} to 1.
  26 #
  27 # If CRUNCH_GENERATE_LINKS is set to no, no links will be generated.
