I want to make a standard make/smake/pmake rule for the depend: pseudotarget. Then I want to include the list of target rules generated by makedepend, but if the file generated by makedepend is not found, make aborts. Now how can I get around this circular problem: If Makedepend is not found as an include file, just run mkdepend instead of aborting! Also, how can I make all of the .c or .h files a dependency for depend : ?

Take a look at /usr/include/make/commonrules (and its predecessor in the same directory, commondefs). These files are used by almost all SGI makefiles. Commonrules contains a big depend rule with some gory SGI-specific multipleple-product-handling code in it, and a separate incdepend rule that relates a timestamp file to the source files (the .c and .h files you mention). We keep incdepend separate from depend so that one can re-make all dependencies without having to remove the timestamp file. Commonrules wants you to list your source files in CFILES, C++FILES, &c. It uses SGI's "sinclude" extension to make(1) (also supported by smake) to include the generated make dependencies from a separate file if it exists, and to silently proceed if the file to include can't be found. Thus, you could write a depend rule that tests for the existence and non-emptiness of this Makedepend file and run mkdepend if (despite the fact that make already performed the sinclude) no such file existed. But you would then want make to re-read the makefile and re-sinclude the new dependencies. This would suggest bailing out with a word of advice to the user, or a recursive invocation of $(MAKE). Are you using mkdepend(1), X's makedepend, a combination of these, or something else? /be

What I do in my makefiles is something like the following:
OBJS = .o files...
..
depend: $(OBJS:.o=.c)
makedepend -- $(CFLAGS) -- $(OBJS:.o=.c)
By using the modifier on the OBJS variable, I only have to maintain a
single list of object files. For automated RCS updates, I also have a
list of header files which goes along with the OBJS... Also, if you do
mixed-language work, you can define say FOBJS for FORTRAN stuff, and
COBJS for C stuff. Oh, if you _do_ do mixed-language programming, I
have a little shell script which will generate FORTRAN dependencies for
you. It works in conjunction with makedepend (for any C files) to generate
a new dependency list.
