If CRUNCH_GENERATE_LINKS is set to "no", then no links will be generated. This defaults to "yes" so things like release crunch building still works.

# 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.
