Makefile

# -*- makefile-bsdmake -*-
#
#	Makefile - of the BSD variety
#
# (on older Mac OS X, use "bsdmake"; on macOS install "bmake")
#
# If using "make progname" then use "LDLIBS+=-llibrary" or, if necessary,
# "LDLIBS+='-L/usr/pkg/lib -llibrary'" to add libraries to the command line as
# this uses the ".c:" rule in <sys.mk> (i.e. <bsd.suffixes.mk> on FreeBSD, or
# <suffixes.mk> in BMake mk-files).  (Do not use LDFLAGS on the command line,
# though it can be set in the environment.)
#
# If using "make PROG=progname" then use "LDADD+=-llibrary" or, if necessary,
# "LDADD+='-L/usr/pkg/lib -llibrary'" to add libraries to the command line.
#
# Use "CPPFLAGS+=-flags" to add CC flags.  (Do not use CFLAGS on the command
# line, though it can be set in the environment.)
#
# Use "CPPFLAGS+=-S -o -" with a ".o" target to see assembler.
#
# Use "CSTD=c90" to set a specific C standard.  (The default is c89.)
#
# Use "OPTIM=-O0" to set the optimizer level.
#
# Use "DBG=-g3" to set the debugger level for GCC.
#
# Use "PEDANTIC=no" to turn off '-pedantic'.
#
# See also "Makefile.compiler", e.g. for sanitizer options.

# This Makefile works with NetBSD Make, OSX bsdmake, Pkgsrc bmake (on OSX/Darwin
# one must set "SHLIB_MAJOR= SHLIB_MINOR= SHLIB_TEENY=" because Pkgsrc's
# bootstrap-mk-files (as of 20160411) are not yet fully ported to OSX/Darwin),
# and Simon Gerraty's Bmake & Mk-files from http://www.crufy.net/FreeWare/.
#
# Pkgsrc will install on a vast number of systems, including MS-Windows with
# Cygwin.  Simon's Bmake works on many Unix-like systems.

# You can define USE_UBSAN or USE_ASAN on the command line to enable the
# Undefined or Address sanitizers with recent enough Clang or GCC.  Note if your
# system supports these you may of course use its way of enabling them instead
# (e.g. on NetBSD set "MKSANITIZER=yes USE_SANITIZER=address").
#
# N.B.:  The address sanitizer is not available when the PaX ASLR (Address Space
# Layout Randomization) feature is enabled on a given system, but it can be
# disabled for a given binary with paxctl(8):  paxctl +a ${prog}
