# we have to set these in this file rather than in so_commondefs
# because otherwise, $(DEFINES) doesn't get used.
# we set the SO_SHLIBDEFS and SO_SHLIBOPTS here so that we only
# have to set them once (not once for debug, once for optimze, once for profile)

# The following stuff makes .o's get built directly into the library:

# This puts out of date object files into the archive.  The dependency
# is a features of smake; it makes the library dependent on date of
# the .o's inside it, which are, of course, dependent on their source
# files.  .OODATE will be the list of .o's that are out of date.

# We have to redefine clean to remove .o's from the library.
# Unfortunately, we can't just use 'ar -d $(SOLIB) $(OBJECTS)' because
# ar will complain if SOLIB doesn't exist, or if any of the OBJECTS
# aren't in the archive.  Hence, the complicated code below:

clean: $(COMMONPREF)$$@

		$(AR) d $(SOLIB) $$JUNK ; \

# Treat all of the rest of the COMMONTARGS normally.
# The :S/// stuff is a feature of smake; it removes part of the variable.
