Attached is my current portfile which builds both a static archive and dynamic library.

The last thing to do is build the example programs that can be used to test Tarcs:

#for the second pass through WRKSRC_SHARED, use a nonexistent MAKEOBJDIR to
71	#prevent make from entering the obj subdirectories and breaking the build (see,
72	#for example, the description of .OBJDIR in make(1)):
73	        (cd ${WRKSRC}_SHARED && \
74	                ${SETENV} ${MAKE_ENV} MAKEOBJDIR="${NONEXISTENT}" \
75	                ${MAKE} ${_MAKE_JOBS} ${MAKE_ARGS} ${BINS:S|^|bin/FreeBSD/|})

which corresponds to

$(DIREXE)direct$(EXEEXT): $(STDDEPS) $(DIROBJ)direct$(OBJEXT) $(DIRLIB)libtaucs$(LIBEXT)
	$(LD) $(LDFLAGS) \
	$(LOUTFLG)$(DIREXE)direct$(EXEEXT) \
	$(DIROBJ)direct$(OBJEXT) \
	-L$(DIRLIB) -ltaucs \
	$(LIBS)
$(DIREXE)taucs_run$(EXEEXT): $(STDDEPS) $(DIROBJ)taucs_run$(OBJEXT) $(DIRLIB)libtaucs$(LIBEXT)
	$(LD) $(LDFLAGS) \
	$(LOUTFLG)$(DIREXE)taucs_run$(EXEEXT) \
	$(DIROBJ)taucs_run$(OBJEXT) \
	-L$(DIRLIB) -ltaucs \
	$(LIBS)
$(DIREXE)iter$(EXEEXT): $(STDDEPS) $(DIROBJ)iter$(OBJEXT) $(DIRLIB)libtaucs$(LIBEXT)
	$(LD) $(LDFLAGS) \
	$(LOUTFLG)$(DIREXE)iter$(EXEEXT) \
	$(DIROBJ)iter$(OBJEXT) \
	-L$(DIRLIB) -ltaucs \
	$(LIBS)

in the makefile. They set a nonexistent directory using OBJDIR with BSD make. Gnu make does not have this option, does it? It seems rediculus to have to build the library each time. Can I issue these with ‘system', omitting the library object?
