ACE Tutorial 005
On the road to a multithreaded server


Before we go, I wanted you to see the Makefile.

#  Local macros
#----------------------------------------------------------------------------

# You can generally find a Makefile in the ACE examples, tests or the library
# itself that will satisfy our application needs.  This one was taken from
# one of the examples.

  # Define the name of the binary we want to create.  There has to be
  # a CPP file $(BIN).cpp but it doesn't necessarily have to have your
  # main() in it.  Most of the time, though, it will.
BIN    = server

  # Few applications will have a single source file.  We use the FILES
  # macro to build up a list of additional files to compile.  Notice
  # that we leave off the extension just as with BIN
FILES  =
FILES += client_handler

  # The BUILD macro is used by the ACE makefiles.  Basically, it tells
  # the system what to build.  I don't really know what VBIN is other
  # than it is constructed from the value of BIN.  Just go with it...
BUILD  = $(VBIN)

  # Here we use some GNU make extensions to build the SRC macro. Basically,
  # we're just adding .cpp to the value of BIN and for each entry of the
  # FILES macro.
SRC = $(addsuffix .cpp,$(BIN)) $(addsuffix .cpp,$(FILES))

  # This is used by my Indent target below.  It's not a part of standard
  # ACE and you don't need it yourself.
HDR = *.h

#----------------------------------------------------------------------------
#  Include macros and targets
#----------------------------------------------------------------------------

  # This is where the real power lies!  These included makefile components
  # are similar to the C++ templates in ACE.  That is, they do a tremendous
  # amount of work for you and all you have to do is include them.
  # As a matter of fact, in our project, I created a single file named
  # "app.mk" that includes all of these.  Our project makefiles then just
  # need to include app.mk to get everything they need.

include  $(ACE_ROOT)/include/makeinclude/wrapper_macros.GNU

#  Local targets
#----------------------------------------------------------------------------

  # Sometimes I like to reformat my code to make it more readable.  This is
  # more useful for the comments than anything else.  Unfortunately, the
  # "indent" program doesn't quite grok C++ so I have to post-process it's
  # output just a bit.
Indent : #
  for i in $(SRC) $(HDR) ; do \
    indent -npsl -l80 -fca -fc1 -cli0 -cdb < $$i | \
      sed -e 's/: :/::/g'  \
          -e 's/^.*\(public:\)/\1/' \
          -e 's/^.*\(protected:\)/\1/' \
          -e 's/^.*\(private:\)/\1/' \
          -e 's/:\(public\)/ : \1/' \
          -e 's/:\(protected\)/ : \1/' \
          -e 's/:\(private\)/ : \1/' \
      > $$i~ ;\
    mv $$i~ $$i ;\
  done

  # One of the targets in the ACE makefiles is "depend".  It will invoke
  # your compiler in a way that will generate a list of dependencies for
  # you.  This is a great thing!  Unfortunately, it puts all of that mess
  # directly into the Makefile.  I prefer my Makefile to stay clean and
  # uncluttered.  The perl script referenced here pulls the dependency
  # stuff back out of the Makefile and into a file ".depend" which we then
  # include just like the makefile components above.
  #
  # NOTE:  The 'depend' target expects to have GCC available.
  # You can do the same thing with other compilers  but the ACE
  # makefiles and utilities are only wired up to work with GCC.
Depend : depend
  perl ../fix.Makefile

.depend : #
  touch .depend


HTML : #
  [ -f hdr ] || $(MAKE) UNSHAR
  perl ../combine *.pre ; chmod +r *.html

SHAR : #
  [ ! -f combine.shar ] || exit 1
  shar -T hdr bodies *.pre > combine.shar && $(RM) hdr bodies *.pre *.pst

UNSHAR : #
  sh combine.shar

CLEAN : realclean
  $(RM) hdr bodies *.pre *.pst .depend

#----------------------------------------------------------------------------
#  Dependencies
#----------------------------------------------------------------------------

  # Don't put anything below here.  Between the "depend" target and fix.Makefile
  # it's guaranteed to be lost!

  # This is inserted by the fix.Makefile script
include .depend
