# Filename:	Makefile
# Purpose:	Makefile for the AGC simulation,
# Mods:		04/05/03 RSB.	Began.
#		04/21/03 RSB.	Added libyaAGC.a.
#		05/09/04 RSB	Added CheckDec.
#		05/12/04 RSB	Added Backtrace.
#		05/14/04 RSB	Added PREFIX-related stuff.
#		05/30/04 RSB	Added the -Wall switch.
#		08/09/04 RSB	Incorporated nbfgets.
#		08/18/04 RSB	Added SocketAPI.
#				Added the embedded demo thing.
#		08/24/04 RSB	Added some provision for sdcc.  
#				... But foolishly did it before remembering
#				that the ROM requirements of the AGC already
#				overwhelm any 8-bit CPU.
#		04/30/05 RSB	Added CFLAGS
#		06/02/05 RSB	Fixed CFLAGS.
#		06/27/05 RSB	Added DecodeDigitalDownlink.
#		07/30/05 JMS	Added compiling of libreadline
#		08/04/05 RSB	Added the CURSES variable.
#		08/06/05 RSB	... removed it again, and added a path
#				where libcurses.a can be found on some systems.
#				(Sometimes it is in /usr/lib, sometimes in
#				/usr/lib/curses, maybe other places as well.
#		03/06/09 RSB	Added 'all-archs' target, and made other 
#				adjustments related to building for multiple
#				target architectures using IMCROSS.
#		03/08/09 RSB	Added WinAGC.exe
#		........ OH	... something ...
#		04/24/09 RSB	Removed regex.o from OBJECTS.  Redefined
#				CSOURCE, from OBJECTS.  Conditioned
#				use of -lcurses.  Added READLINE back into
#				Win32 and Mac targets.
#		04/25/09 RSB	Fixed up native-Mac builds.
#		05/03/09 RSB	Adjusted for SOLARIS.
#		08/01/09 RSB	Added NormalizeSourceName.o.  Disabling
#				readline support for Win32 because of 
#				bad Vista problems.  ... No, couldn't
#				get rid of it.  Adjusted to link
#				to libcurses, to try and use a newer version
#				of libreadline.
#		08/02/09 RSB	Added Alberto Galdo's iPhone mods.
#		2012-09-16 JL	Updated to match tools directory changes.
#		2016-08-06 RSB  This had been set to build yaAGC statically-linked
#				for USERNAME=rburkey (me!) and dynamically-linked
#				for everyone else.  That's because I would often
#				build it for the purpose of making an installer,
#				and it was easier if the executables were statically
#				linked to the extent possible.  But it turns out 
#				that the standard library function gethostbyname()
#				used by agc_utilities.c no longer works (at least on
#		                some Linux distributions) if statically 
#		                linked.  Therefore, I need to make this change
#				to fix the symptoms I was seeing (namely, that 
#				yaAGC no longer listened on the specified port
#				on 64-bit Linux Mint and Ubuntu).  Neither the
#				problem nor the fix presumably affects anybody 
#				else's builds.
#		2016-11-12 RSB	"Permanently" disabled READLINE.
#		2016-11-18 RSB	Explicitly include socket library in Solaris.
#		2021-05-13 MKF	Defined WASI and targets yaAGC.wasm, yaAGC.wast.
