# Name:    Makehead.cygwin
#
# Purpose: This file is used to customize operating system and installation
#          dependent features of the MX makefiles.  This version is customized
#          for Cygwin under Microsoft Win32.
#
#          Cygwin may be found at http://sources.redhat.com/cygwin/
#          or http://cygwin.com/
#
# Normally, the only things that end users may have to modify in this file are
# the definitions of INCLUDES, LIB_DIRS, and LIBRARIES.  If you want to speed
# up the build by linking everything statically, you may want to set the
# BUILD_LIBMX_DLL variable to 'no'.
#

INCLUDES	= $(MX_INCLUDES)
#
LIB_DIRS	= -L$(MX_LIB_DIR)
LIBRARIES	= -lrpclib

#
# Currently I build libMx.dll and its export library libMx.dll.a using
# the Cygwin 'dllwrap' utility.  Unfortunately, generating the export
# library takes a very long time, sometimes over 10 minutes, since libMx
# has so many symbols.  Most of this time is taken up by 'dlltool' which
# has to create around 4000 temporary files with names like ds0432.o, etc.
# in order to create the export library libMx.dll.a.  Thus, when you are
# debugging libMx on Cygwin, you probably want to set BUILD_LIBMX_DLL
# to 'no' while debugging and only set it to 'yes' when you are doing
# your final build.  However, this is still better than trying to use
# a libMx.def file which would have so many entries and change so often
# that it would be almost impossible to maintain.
#
# Theoretically, Cygwin's __attribute__((dllexport)) feature might be
# a way to cut down on the build time in analogy to the way that the
# Visual C++ _declspec(dllexport) feature does.  Unfortunately, so far
# any attempt to build libMx.dll.a seems to require the 10 minute wait
# to create all the ds*.o files even if you are using the dllexport
# attribute.  Probably I do not understand how to correctly use this
# feature yet, so if somebody can make this work, I would be interested
# in hearing about it.
