Masahiro Yamada | 6825a95 | 2014-02-04 17:24:28 +0900 | [diff] [blame] | 27 | # We are using a recursive build, so we need to do a little thinking |
| 28 | # to get the ordering right. |
| 29 | # |
| 30 | # Most importantly: sub-Makefiles should only ever modify files in |
| 31 | # their own directory. If in some directory we have a dependency on |
| 32 | # a file in another dir (which doesn't happen often, but it's often |
| 33 | # unavoidable when linking the built-in.o targets which finally |
| 34 | # turn into vmlinux), we will call a sub make in that other dir, and |
| 35 | # after that we are sure that everything which is in that other dir |
| 36 | # is now up to date. |
| 37 | # |
| 38 | # The only cases where we need to modify files which have global |
| 39 | # effects are thus separated out and done before the recursive |
| 40 | # descending is started. They are now explicitly listed as the |
| 41 | # prepare rule. |
| 42 | |
Masahiro Yamada | ffe29eb | 2014-10-30 11:06:11 +0900 | [diff] [blame] | 43 | # Beautify output |
| 44 | # --------------------------------------------------------------------------- |
| 45 | # |
| 46 | # Normally, we echo the whole command before executing it. By making |
| 47 | # that echo $($(quiet)$(cmd)), we now have the possibility to set |
| 48 | # $(quiet) to choose other forms of output instead, e.g. |
| 49 | # |
| 50 | # quiet_cmd_cc_o_c = Compiling $(RELDIR)/$@ |
| 51 | # cmd_cc_o_c = $(CC) $(c_flags) -c -o $@ $< |
| 52 | # |
| 53 | # If $(quiet) is empty, the whole command will be printed. |
| 54 | # If it is set to "quiet_", only the short version will be printed. |
| 55 | # If it is set to "silent_", nothing will be printed at all, since |
| 56 | # the variable $(silent_cmd_cc_o_c) doesn't exist. |
| 57 | # |
| 58 | # A simple variant is to prefix commands with $(Q) - that's useful |
| 59 | # for commands that shall be hidden in non-verbose mode. |
| 60 | # |
| 61 | # $(Q)ln $@ :< |
| 62 | # |
| 63 | # If KBUILD_VERBOSE equals 0 then the above command will be hidden. |
| 64 | # If KBUILD_VERBOSE equals 1 then the above command is displayed. |
