| # 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. |
