5 ## This file is used as part of 'make depend', to produce the
|
|
|
6 ## dependency list for src/Makefile.in.in.
|
|
|

|
|
|
8 ## Unfortunately, makedepend (at least the one that comes as part
|
|
|
9 ## of Open Windows under Solaris) is stupid and doesn't follow the
|
|
|
10 ## documented behavior. So we have to force the definitions of
|
|
|
11 ## certain options through -D flags (even though it's supposed to
|
|
|
12 ## pick this up), and post-process the output to get rid of stuff
|
|
|
13 ## we don't want.
|
|
|
14
|
|
|
15 ## The sed stage gets rid of include files in other directories,
|
|
|
16 ## except for lwlib.h (makedepend puts system include files in,
|
|
|
17 ## which is pretty stupid). We also get rid of some standard
|
|
|
18 ## include files that are in every or pretty much every file
|
|
|
19 ## and where changes in those files don't usually merit
|
|
|
20 ## recompilation of everything. Finally, we eliminate entirely
|
|
|
21 ## the dependencies for some files (such as unex*.c) that get
|
|
|
22 ## screwed up by makedepend. We just put those in by hand at
|
|
|
23 ## the top of the dependency list.
|

|

|
25 ## For Mule, we need to do some additional processing: conversion
|
|
|
26 ## to MULESRCDIR (at least so that the include files don't get
|
|
|
27 ## wiped out by the next stage) and removing the mule/ prefix
|
|
|
28 ## from the object file names.
|

|
30 ## The awk stage puts one dependency per line. Then we pass
|
|
|
31 ## the result through sort and uniq (makedepend is supposed
|
|
|
32 ## to not put in duplicate dependencies, but it does so
|
|
|
33 ## occasionally).
|
|
|
34
|
|
|
35 ## After running 'make depend', verify that the output (in
|
|
|
36 ## depend.out) is reasonable and then replace the stuff in
|
|
|
37 ## Makefile.in.in marked "generated by 'make depend'".
