#
# Usage:
#
#	* Options:
#		- DEBUG=[0|1] turn on/off debug MACRO
#		- Version is MAJOR.MINOR.DATE.TIME
#			+ MAJOR=N makes this major version N
#			+ MINOR=N makes this minor version N
#		- OBJ=someobjetc.o : compile and link with objetc or source
#		- You can force update with flag -B
#
# Examples:
#
# * From linux prompt:
#    - Normal C program (ex1.c)
#        $ make ex1.x
#    - Aspipo program (ex1.c) with object:
#        $ make ex1.x OBJ=libaspipo-ux64.o
#    - Multiple objects:
#        $ make ex1.x OBJ="mylib1.o mylib2.o"
#    - Multiple sources to generate a single binary ex1.x:
#    	 $ make ex1.x SRC="mysrc1.c mysrc2.c"
#	 - Normal C program (ex2.c) version 2.3, no debug
#	 	 $ make ex2.x MAJOR=2 MINOR=3 DEBUG=0
#	 - Brainforce:
#	     $ make ex1.bf.x
#	 - Portugol:
#	 	 $ make ex1.gpt.x
#
# * Directly from vim editor command line:
#    - Normal C program (ex1.c)
#        :make ex1.x
#    - Aspipo program (ex1.c)
#        :make ex1.x OBJ=libaspipo-ux64.o
#
# * Copy from 'rascunhos' to 'trabalhos'
# 	- $ make copy PRG=ex1
# 	It will try to copy every file matching patterns:
#		cp ex1.c 		# c source code
#		cp ex1.h 		# c library source code
# 		cp ex1.x 		# binary from c source code
# 		cp ex1.gpt 		# portugol source code
# 		cp ex1.gpt.x 	# binary from portugol source code
# 		cp ex1.bf 		# brainforce source code
# 		cp ex1.bf.x 	# binary from brainforce source code
# 		cp ex1.cpl.x 	# binary from c code with some prolog predicates linked to it
# 		cp ex1.pl 		# prolog source code
# 		cp ex1.pl.x 	# binary from prolog source code
# 		cp ex1.so 		# shared library object from c source code
# 		cp ex1.pl.so 	# c library object with some functions that may be called by a prolog program
# 	to the '../trabalhos' folder
#
# * CTAGS
# 	 - Generate a 'tags' index file with all tags in all C source codes
# 	 	$ make tags
# 	 - Use with vi:
# 	 	:make tags
# 	 	- To find a function or other tag, use $ vim -t tag
# 	 	- Inside vi, use :ta tag
#
#
# * clean
#   Clean temporary files *.o and errors.err
#   	$ make clean
#
# * wipe 
#	- WARNING!! Clean all created files: *.x *.so *.o errors.err and tags
# 		$ make wipe
#
# Log:
# 2017-03-03:
# 		* added -fdiagnostics-color=always to colorize tee output
# 		* added -pg -fprofile-arcs to allow gprof command on debug
# 2017-03-05:
# 		* added variable CCCOLOR to work with vi
# 			- set makeprg=make\ o=%< CCCOLOR=never\ $* 
# 			- set makeprg=make\ %<.x CCCOLOR=never\ $*
# 			- set makeprg=make\ CCCOLOR=never\ $*
#		* added CPPFLAGS += -D$(D) so we can pass values to
#			C-Pre-processor via make prog.x D=VARIABLE=VALUE
# 2017-03-06:
# 		* ifeq "$(DEBUG)" "1" to set CFLAGS
# 		* added _XOPEN_SOURCE=700 to pair with -ansi
# 		* added _FORTIFY_SOURCE=1 to help catch overflows
# 2017-03-18:
# 		* added -lcurl to link with libcurl

# disable builtin rules with MAKEFLAGS and .SUFFIXES
MAKEFLAGS += --no-builtin-rules
#.SUFFIXES:
.PHONY: clean wipe nomatch
