3# NOTE:  Please would any committer updating this file also update the
4# make.conf(5) manual page, if necessary, which is located in
5# src/share/man/man5/make.conf.5.
6#
7# /etc/make.conf, if present, will be read by make (see
8# /usr/share/mk/sys.mk).  It allows you to override macro definitions
9# to make without changing your source tree, or anything the source
10# tree installs.
11#
12# This file must be in valid Makefile syntax.
13#
14# There are additional things you can put into /etc/make.conf.
15# You have to find those in the Makefiles and documentation of
16# the source tree.
17#
18# Note, that you should not set MAKEOBJDIRPREFIX or MAKEOBJDIR
19# from make.conf (or as command line variables to make).
20# Both variables are environment variables for make and must be used as:
21#
22# env MAKEOBJDIRPREFIX=/big/directory make
23#
24#
25# The CPUTYPE variable controls which processor should be targeted for
26# generated code.  This controls processor-specific optimizations in
27# certain code (currently only OpenSSL) as well as modifying the value
28# of CFLAGS to contain the appropriate optimization directive to cc.
29# The automatic setting of CFLAGS may be overridden using the
30# NO_CPU_CFLAGS variable below.
31# Currently the following CPU types are recognized:
32#   Intel x86 architecture:
33#       (AMD CPUs)	amdfam10, opteron-sse3, athlon64-sse3, k8-sse3,
34#			opteron, athlon64, athlon-fx, k8, athlon-mp,
35#			athlon-xp, athlon-4, athlon-tbird, athlon, k7,
36#			geode, k6-3, k6-2, k6
37#       (Intel CPUs)	core2, core, nocona, pentium4m, pentium4, prescott,
38#			pentium3m, pentium3, pentium-m, pentium2,
39#			pentiumpro, pentium-mmx, pentium, i486
40#       (VIA CPUs)	c7, c3-2, c3
41#   AMD64 architecture:	amdfam10, opteron-sse3, athlon64-sse3, k8-sse3,
42#			opteron, athlon64, k8, core2, nocona
43#   SPARC-V9 architecture:	v9 (generic 64-bit V9), ultrasparc (default
44#				if omitted), ultrasparc3
45# Additionally the following CPU types are recognized by clang:
46#   Intel x86 architecture (for both amd64 and i386):
47#       (AMD CPUs)	znver1, bdver4, bdver3, bdver2, bdver1, btver2, btver1
48#       (Intel CPUs)	cascadelake, tremont, goldmont-plus, icelake-server,
49#			icelake-client, cannonlake, knm, skylake-avx512, knl,
50#			goldmont, skylake, broadwell, haswell, ivybridge,
51#			sandybridge, westmere, nehalem, silvermont, bonnell
52#   ARM architecture:	armv5, armv5te, armv6, armv6t2, arm1176jzf-s, armv7,
53#			armv7-a, armv7ve, generic-armv7-a, cortex-a5,
54#			cortex-a7, cortex-a8, cortex-a9, cortex-a12,
55#			cortex-a15, cortex-a17
56#   ARM64 architechture:	cortex-a53, cortex-a57, cortex-a72,
57#				exynos-m1

61#CPUTYPE?=pentium3
62#NO_CPU_CFLAGS=		# Don't add -march=<cpu> to CFLAGS automatically
63#
64# CFLAGS controls the compiler settings used when compiling C code.
65# Note that optimization settings other than -O and -O2 are not recommended
66# or supported for compiling the world or the kernel - please revert any
67# nonstandard optimization settings
68# before submitting bug reports without patches to the developers.
69#
70# CFLAGS.arch provides a mechanism for applying CFLAGS only when building
71# the given architecture.  This is useful primarily on a system used for
72# cross-building, when you have a set of flags to apply to the TARGET_ARCH
73# being cross-built but don't want those settings applied to building the
74# cross-tools or other components that run on the build host machine.
75#
76# CXXFLAGS controls the compiler settings used when compiling C++ code.
77# Note that CXXFLAGS is initially set to the value of CFLAGS.  If you wish
78# to add to CXXFLAGS value, "+=" must be used rather than "=".  Using "="
79# alone will remove the often needed contents of CFLAGS from CXXFLAGS.
80#
81# Additional compiler flags can be specified that extend or override
82# default ones. However, neither the base system nor ports are guaranteed
83# to build and function without problems with non-default settings.
84#
85# CFLAGS+=	-msse3
86# CXXFLAGS+=	-msse3
87# CFLAGS.armv6+= -mfloat-abi=softfp
88#
89# MAKE_SHELL controls the shell used internally by make(1) to process the
90# command scripts in makefiles.  Three shells are supported, sh, ksh, and
91# csh.  Using sh is most common, and advised.  Using ksh *may* work, but is
92# not guaranteed to.  Using csh is absurd.  The default is to use sh.
93#
94#MAKE_SHELL?=sh
95#
96# BDECFLAGS are a set of gcc warning settings that Bruce Evans has suggested
97# for use in developing FreeBSD and testing changes.  They can be used by
98# putting "CFLAGS+=${BDECFLAGS}" in /etc/make.conf.  -Wconversion is not
99# included here due to compiler bugs, e.g., mkdir()'s mode_t argument.
100#
101#BDECFLAGS=	-W -Wall -ansi -pedantic -Wbad-function-cast -Wcast-align \
102#		-Wcast-qual -Wchar-subscripts -Winline \
103#		-Wmissing-prototypes -Wnested-externs -Wpointer-arith \
104#		-Wredundant-decls -Wshadow -Wstrict-prototypes -Wwrite-strings
105#
106# To compile just the kernel with special optimizations, you should use
107# this instead of CFLAGS (which is not applicable to kernel builds anyway).
108# There is very little to gain by using higher optimization levels, and doing
109# so can cause problems.

252#	SENDMAIL_LDFLAGS=-L/usr/local/lib
253#	SENDMAIL_LDADD=-lsasl2
254#
255# Note: If you are using Cyrus SASL with other applications which require
256#	access to the sasldb file, you should add the following to your
257#	sendmail.mc file:

266# Setting SENDMAIL_SET_USER_ID will install the sendmail binary as a
267# set-user-ID root binary instead of a set-group-ID smmsp binary and will
268# prevent the installation of /etc/mail/submit.cf.
