I have a problem with make on a Sun 3/80 running SunOs 4.0.3 that I have spent the past two days trying to solve. The makefile in my main working directory must be capabale of building 30+ different executables from about 45 common source files and 1 uniques source file per executable. Make has handled of all this nicely with just one command line arguement. Recently I decided it would be advantageous to have my makefile manage separate directories for each of debugabble, profiled and clean object files and executables. I would like to add a second command line option an addition target or a macro to choose which class of compilation will occur each time. So far the best I have managed to come up with is to have a separate macro DIR defined on the command line. I define DIR to be the profile, debug or clean and then use a pattern dependancy rule for each directory which gets the various flags set correctly for each source compilation. The problem comes from the fact that this requires 3 sets of rules for each executable profiles/pr:~$(PR_OBJECTS) $(LIB_DEP) ~gcc -pg $(OPT) -o $@ $(PR_OBJECTS) $(LIB_PATH) $(LIBS) ~beep debug/pr:~$(PR_DB_OBJECTS) ~cc -g -o $@ $(PR_DB_OBJECTS) $(DB_LIB_PATH) $(DB_LIBS) ~beep clean/pr:~$(PR_OBJECTS) $(LIB_DEP) ~gcc $(OPT) -o $@ $(PR_OBJECTS) $(LIB_PATH) $(LIBS) ~beep note that the important difference between debug and profiles, clean is that for profiles and clean of source files except the one containing the main function are placed in library, while the debugabble version just links all of the object files. So I guess what I need is based on the value of the second parameter to make be able to set the values for a number of macros. Short of writing a C program or using make to call make with all the right macros defined does anyone have any good ideas? Mark Levison levisonm@qucis.queensu.ca

Two possibilities: (1) Use four Makefiles --- one each for profiles, debug, and clean, which define macros, and a fourth which is included into the other three and defines the actual rules in terms of those macros. "make -f profiles.mk", for example, would build the profiling version. Drawback: since make doesn't realize you're playing games, you must "touch" the sourrce files to force recompilation from one form to another. (2) Get the "shape" distribution from the comp.sources.unix archives. It has built-in support for this sort of thing, as well as many other features. ++Brandon -- Me: Brandon S.
