7 # /etc/make.conf, if present, will be read by make (see

9 # to make without changing your source tree, or anything the source
12 # This file must be in valid Makefile syntax.
14 # There are additional things you can put into /etc/make.conf.
15 # You have to find those in the Makefiles and documentation of
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:
22 # env MAKEOBJDIRPREFIX=/big/directory make
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) znver3, znver2, znver1, bdver4, bdver3, bdver2, bdver1,
34 # btver2, btver1, amdfam10, opteron-sse3, athlon64-sse3,

57 #NO_CPU_CFLAGS= # Don't add -march=<cpu> to CFLAGS automatically
59 # CFLAGS controls the compiler settings used when compiling C code.
60 # Note that optimization settings other than -O and -O2 are not recommended
61 # or supported for compiling the world or the kernel - please revert any
62 # nonstandard optimization settings
63 # before submitting bug reports without patches to the developers.
65 # CFLAGS.arch provides a mechanism for applying CFLAGS only when building
66 # the given architecture. This is useful primarily on a system used for
67 # cross-building, when you have a set of flags to apply to the TARGET_ARCH
68 # being cross-built but don't want those settings applied to building the
69 # cross-tools or other components that run on the build host machine.
71 # CXXFLAGS controls the compiler settings used when compiling C++ code.
72 # Note that CXXFLAGS is initially set to the value of CFLAGS. If you wish
73 # to add to CXXFLAGS value, "+=" must be used rather than "=". Using "="
74 # alone will remove the often needed contents of CFLAGS from CXXFLAGS.
76 # Additional compiler flags can be specified that extend or override
77 # default ones. However, neither the base system nor ports are guaranteed
78 # to build and function without problems with non-default settings.
82 # CFLAGS.armv6+= -mfloat-abi=softfp
84 # MAKE_SHELL controls the shell used internally by make(1) to process the
85 # command scripts in makefiles. Three shells are supported, sh, ksh, and
86 # csh. Using sh is most common, and advised. Using ksh *may* work, but is
87 # not guaranteed to. Using csh is absurd. The default is to use sh.
91 # BDECFLAGS are a set of gcc warning settings that Bruce Evans has suggested
92 # for use in developing FreeBSD and testing changes. They can be used by
93 # putting "CFLAGS+=${BDECFLAGS}" in /etc/make.conf. -Wconversion is not
94 # included here due to compiler bugs, e.g., mkdir()'s mode_t argument.
96 #BDECFLAGS= -W -Wall -ansi -pedantic -Wbad-function-cast -Wcast-align \
97 # -Wcast-qual -Wchar-subscripts -Winline \

99 # -Wredundant-decls -Wshadow -Wstrict-prototypes -Wwrite-strings
101 # To compile just the kernel with special optimizations, you should use
102 # this instead of CFLAGS (which is not applicable to kernel builds anyway).

160 # By default, the system will always use the keyboard/video card as system
161 # console. However, the boot blocks may be dynamically configured to use a
162 # serial port in addition to or instead of the keyboard/video console.

249 # access to the sasldb file, you should add the following to your
252 # define(`confDONT_BLAME_SENDMAIL',`GroupReadableSASLDBFile')
259 # Setting SENDMAIL_SET_USER_ID will install the sendmail binary as a
260 # set-user-ID root binary instead of a set-group-ID smmsp binary and will
