In this case we ## can skip the use of depcomp and easily inline the dependency ## tracking. ## Verbosity of FASTDEP rules ## -------------------------- ## (1) Some people want to see what happens during make. They think ## @-commands are evil because hiding things hinders debugging. ## (2) Other people want to see only the important commands--those that ## may produce diagnostics, such as compiler invocations. They ## do not care about build details such as dependency generation ## (the if/then/else machinery in FASTDEP rules). Their point is ## that it is hard to spot diagnostics in a verbose output. ## (3) Other people want `make -s' to work as expected: silently. ## This way they can spot any diagnostic really easily. ## ## The second point suggests we hide rules with @ and that we `echo' ## only the relevant parts. However this goes against the two others. ## There are regular complaints about this on the mailing list, but ## it's hard to please everybody. On April 2003, William Fulton (from ## clan (3)) and Karl Berry (from clan (2)) agreed that folding the ## compile rules so that they are output on a single line (instead of 5) ## would be a good compromise. Actually we use two lines rather than one, ## because this way %SOURCE% is always located at the end of the first ## line and is therefore easier to spot.
