# Generate crunched binaries using crunchgen(1).
|
|
#
|
|
# General notes:
|
|
#
|
|
# A number of Make variables are used to generate the crunchgen config file.
|
|
#
|
|
# CRUNCH_SRCDIRS: lists directories to search for included programs
|
|
# CRUNCH_PROGS: lists programs to be included
|
|
# CRUNCH_LIBS: libraries to statically link with
|
|
# CRUNCH_SHLIBS: libraries to dynamically link with
|
|
# CRUNCH_BUILDOPTS: generic build options to be added to every program
|
|
# CRUNCH_BUILDTOOLS: lists programs that need build tools built in the
|
|
# local architecture.
|
|
#
|
|
# Special options can be specified for individual programs
|
|
# CRUNCH_SRCDIR_${P}: base source directory for program ${P}
|
|
# CRUNCH_BUILDOPTS_${P}: additional build options for ${P}
|
|
# CRUNCH_ALIAS_${P}: additional names to be used for ${P}
|
|
#
|
|
# By default, any name appearing in CRUNCH_PROGS or CRUNCH_ALIAS_${P}
|
|
# will be used to generate a hard link to the resulting binary.
|
|
# Specific links can be suppressed by setting
|
|
# CRUNCH_SUPPRESS_LINK_${NAME} to 1.
|
|
#
|
|
# If CRUNCH_GENERATE_LINKS is set to no, no links will be generated.
