-7.8 Custom kbuild commands
---------------------------
-
- When kbuild is executing with KBUILD_VERBOSE=0, then only a shorthand
- of a command is normally displayed.
- To enable this behaviour for custom commands kbuild requires
- two variables to be set::
-
- quiet_cmd_<command> - what shall be echoed
- cmd_<command> - the command to execute
-
- Example::
-
- #
- quiet_cmd_image = BUILD $@
- cmd_image = $(obj)/tools/build $(BUILDFLAGS) \
- $(obj)/vmlinux.bin > $@
-
- targets += bzImage
- $(obj)/bzImage: $(obj)/vmlinux.bin $(obj)/tools/build FORCE
- $(call if_changed,image)
- @echo 'Kernel: $@ is ready'
-
- When updating the $(obj)/bzImage target, the line:
-
- BUILD arch/x86/boot/bzImage
-
- will be displayed with "make KBUILD_VERBOSE=0".
