echo -e is not a portable way to do this, better use printf. Works with MacOS X. Signed-off-by: Waldemar Brodkorb <mail@waldemar-brodkorb.de> Acked-by: Arnout Vandecappelle (Essensium/Mind) <arnout@mind.be> Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>

# Macro that builds the needed Makefile target to create a root
|
|
# filesystem image.
|
|
#
|
|
# The following variable must be defined before calling this macro
|
|
#
|
|
# ROOTFS_$(FSTYPE)_CMD, the command that generates the root
|
|
# filesystem image. A single command is allowed. The filename of the
|
|
# filesystem image that it must generate is $$@.
|
|
#
|
|
# The following variables can optionaly be defined
|
|
#
|
|
# ROOTFS_$(FSTYPE)_DEPENDENCIES, the list of dependencies needed to
|
|
# build the root filesystem (usually host tools)
|
|
#
|
|
# ROOTFS_$(FSTYPE)_PRE_GEN_HOOKS, a list of hooks to call before
|
|
# generating the filesystem image
|
|
#
|
|
# ROOTFS_$(FSTYPE)_POST_GEN_HOOKS, a list of hooks to call after
|
|
# generating the filesystem image
|
|
#
|
|
# ROOTFS_$(FSTYPE)_POST_TARGETS, the list of targets that should be
|
|
# run after running the main filesystem target. This is useful for
|
|
# initramfs, to rebuild the kernel once the initramfs is generated.
|
|
#
|
|
# In terms of configuration option, this macro assumes that the
|
|
# BR2_TARGET_ROOTFS_$(FSTYPE) config option allows to enable/disable
|
|
# the generation of a filesystem image of a particular type. If
|
|
# configura options BR2_TARGET_ROOTFS_$(FSTYPE)_GZIP,
|
|
# BR2_TARGET_ROOTFS_$(FSTYPE)_BZIP2 or
|
|
# BR2_TARGET_ROOTFS_$(FSTYPE)_LZMA exist and are enabled, then the
|
|
# macro will automatically generate a compressed filesystem image.
