# We are using a recursive build, so we need to do a little thinking # to get the ordering right. # # Most importantly: sub-Makefiles should only ever modify files in # their own directory. If in some directory we have a dependency on # a file in another dir (which doesn't happen often, but it's often # unavoidable when linking the built-in.o targets which finally # turn into vmlinux), we will call a sub make in that other dir, and # after that we are sure that everything which is in that other dir # is now up to date. # # The only cases where we need to modify files which have global # effects are thus separated out and done before the recursive # descending is started. They are now explicitly listed as the # prepare rule. |

# Beautify output # --------------------------------------------------------------------------- # # Normally, we echo the whole command before executing it. By making # that echo $($(quiet)$(cmd)), we now have the possibility to set # $(quiet) to choose other forms of output instead, e.g. # # quiet_cmd_cc_o_c = Compiling $(RELDIR)/$@ # cmd_cc_o_c = $(CC) $(c_flags) -c -o $@ $< # # If $(quiet) is empty, the whole command will be printed. # If it is set to "quiet_", only the short version will be printed. # If it is set to "silent_", nothing will be printed at all, since # the variable $(silent_cmd_cc_o_c) doesn't exist. # # A simple variant is to prefix commands with $(Q) - that's useful # for commands that shall be hidden in non-verbose mode. # # $(Q)ln $@ :< # # If KBUILD_VERBOSE equals 0 then the above command will be hidden. # If KBUILD_VERBOSE equals 1 then the above command is displayed. # |
