Sun)# You will notice below a "#ranlib ..." line; if your machine needs it,# remove the "#".## Please modify the Makefile below for the following exceptions:## Compiler Exceptions     Loader Exceptions#                              SCO#                              Solaris 2.1## You may also wish to set the "RDCOLOR" environment variable in your# login/profile/startup-sequence/etc file to be the string where the# <rdcolor.dat> file is to be located.  Furthermore, you may wish to# modify the <rdcolor.dat> file to include escape sequences for your# favorite terminal(s) (should be fairly obvious by inspection how to# do so using some editor).## Option: The PortMaster can optionally use a "firewall" to keep unwanted#         visitors out.  The PortMaster (Spm) uses an environment variable#         (SPMFIREWALL) to specify where the firewall file is located.#         One may also start up the PortMaster (Spm -f firewallfilename).#         Please read the documentation on this.OBJ = Saccept.o      Sprintf.o      Stest.o        outofmem.o     \      Sclose.o       Sprtskt.o      Stimeoutwait.o rdcolor.o      \      Sgets.o        Sputs.o        Svprintf.o     sprt.o         \      Smaskwait.o    Sread.o        Swait.o        srmtrblk.o     \      Smkskt.o       Sreadbytes.o   Swrite.o       stpblk.o       \      Sopen.o        Srmsrvr.o      error.o        stpnxt.o       \      Sopenv.o       Sscanf.o       fopenv.o       strnxtfmt.o    \      Speek.o        cprt.o         Speername.o    Speeraddr.o    \	  Sinit.o# LIB: name of libraryLIB       = simpleskts.a# EXETGT: where to put executables, as seen from the viewpoint of the EXE#  subdirectoryEXETGT=../EXE# usual compiler stuffCFLAGS    = -O -I./HDRLOADLIBES = ../$(LIB)# for SCO UNIX:# LOADLIBES = ../$(LIB) -lsocket# for Solaris 2.1# LOADLIBES = ../$(LIB) -lnsl# for g++ compiler: (tnx to Gary Johnson)# CFLAGS= -Wall -ansi -pedantic -O -I./HDRall     : $(LIB) exes examples$(LIB)  : $(OBJ)	ar r simpleskts.a *.o#	ranlib simpleskts.a#	/bin/rm -f *.o	@echo "finished updating simpleskts.a"exes : $(LIB)	( cd EXE;                                                  \      make LIB=$(LIB) CFLAGS="-O -I../HDR" LOADLIBES=$(LOADLIBES) EXETGT=$(EXETGT) )examples : $(LIB)	( cd EXAMPLES;                                             \      make LIB=$(LIB) CFLAGS="-O -I../HDR" LOADLIBES=$(LOADLIBES) )clean   :	@/bin/rm -f *.a *.bak *.err $(OBJ)	(cd EXE; make clean )	(cd EXAMPLES ; make clean )	@echo "All object files, the simpleskts library, and executables are now gone"
