haproxy/Makefile

# This GNU Makefile supports different OS and CPU combinations.
#
# You should use it this way :
#   [g]make TARGET=os ARCH=arch CPU=cpu USE_xxx=1 ...
#
# Valid USE_* options are the following. Most of them are automatically set by
# the TARGET, others have to be explictly specified :
#   USE_CTTPROXY         : enable CTTPROXY on Linux (needs kernel patch).
#   USE_DLMALLOC         : enable use of dlmalloc (see DLMALLOC_SRC)
#   USE_EPOLL            : enable epoll() on Linux 2.6. Automatic.
#   USE_GETSOCKNAME      : enable getsockname() on Linux 2.2. Automatic.
#   USE_KQUEUE           : enable kqueue() on BSD. Automatic.
#   USE_MY_EPOLL         : redefine epoll_* syscalls. Automatic.
#   USE_NETFILTER        : enable netfilter on Linux. Automatic.
#   USE_PCRE             : enable use of libpcre for regex. Recommended.
#   USE_POLL             : enable poll(). Automatic.
#   USE_REGPARM          : enable regparm optimization. Recommended on x86.
#   USE_SEPOLL           : enable speculative epoll(). Automatic.
#   USE_STATIC_PCRE      : enable static libpcre. Recommended.
#   USE_TPROXY           : enable transparent proxy. Automatic.
#   USE_LINUX_TPROXY     : enable full transparent proxy (needs kernel 2.6.28).
#   USE_LINUX_SPLICE     : enable kernel 2.6 splicing (broken on old kernels)
#   USE_LIBCRYPT         : enable crypted passwords using -lcrypt
#   USE_CRYPT_H          : set it if your system requires including crypt.h
#
# Options can be forced by specifying "USE_xxx=1" or can be disabled by using
# "USE_xxx=" (empty string).
#
# Variables useful for packagers :
#   CC is set to "gcc" by default and is used for compilation only.
#   LD is set to "gcc" by default and is used for linking only.
#   ARCH may be useful to force build of 32-bit binary on 64-bit systems
#   CFLAGS is automatically set for the specified CPU and may be overridden.
#   LDFLAGS is automatically set to -g and may be overridden.
#   SMALL_OPTS may be used to specify some options to shrink memory usage.
#   DEBUG may be used to set some internal debugging options.
#   ADDINC may be used to complete the include path in the form -Ipath.
#   ADDLIB may be used to complete the library list in the form -Lpath -llib.
#   DEFINE may be used to specify any additional define, which will be reported
#          by "haproxy -vv" in CFLAGS.
#   SILENT_DEFINE may be used to specify other defines which will not be
#     reported by "haproxy -vv".
#   DESTDIR is not set by default and is used for installation only.
#           It might be useful to set DESTDIR if you want to install haproxy
#           in a sandbox.
#   PREFIX  is set to "/usr/local" by default and is used for installation only.
#   SBINDIR is set to "$(PREFIX)/sbin" by default and is used for installation
#           only.
#   MANDIR  is set to "$(PREFIX)/share/man" by default and is used for
#           installation only.
#   DOCDIR  is set to "$(PREFIX)/doc/haproxy" by default and is used for
#           installation only.
#
# Other variables :
#   DLMALLOC_SRC   : build with dlmalloc, indicate the location of dlmalloc.c.
#   DLMALLOC_THRES : should match PAGE_SIZE on every platform (default: 4096).
#   PCREDIR        : force the path to libpcre.
#   IGNOREGIT      : ignore GIT commit versions if set.
#   VERSION        : force haproxy version reporting.
#   SUBVERS        : add a sub-version (eg: platform, model, ...).
#   VERDATE        : force haproxy's release date.

#### Installation options.
DESTDIR =
PREFIX = /usr/local
SBINDIR = $(PREFIX)/sbin
MANDIR = $(PREFIX)/share/man
DOCDIR = $(PREFIX)/doc/haproxy

#### TARGET system
# Use TARGET=<target_name> to optimize for a specifc target OS among the
# following list (use the default "generic" if uncertain) :
#    generic, linux22, linux24, linux24e, linux26, solaris,
#    freebsd, openbsd, cygwin, custom
TARGET =

#### TARGET CPU
# Use CPU=<cpu_name> to optimize for a particular CPU, among the following
# list :
#    generic, i586, i686, ultrasparc, custom
CPU = generic

#### Architecture, used when not building for native architecture
# Use ARCH=<arch_name> to force build for a specific architecture. Known
# architectures will lead to "-m32" or "-m64" being added to CFLAGS and
# LDFLAGS. This can be required to build 32-bit binaries on 64-bit targets.
# Currently, only x86_64, i386, i486, i586 and i686 are understood.
ARCH =

#### Toolchain options.
# GCC is normally used both for compiling and linking.
CC = gcc
LD = $(CC)

#### Debug flags (typically "-g").
# Those flags only feed CFLAGS so it is not mandatory to use this form.
DEBUG_CFLAGS = -g

#### Memory usage tuning
# If small memory footprint is required, you can reduce the buffer size. There
# are 2 buffers per concurrent session, so 16 kB buffers will eat 32 MB memory
# with 1000 concurrent sessions. Putting it slightly lower than a page size
# will prevent the additional parameters to go beyond a page. 8030 bytes is
# exactly 5.5 TCP segments of 1460 bytes and is generally good. Useful tuning
# macros include :
#    SYSTEM_MAXCONN, BUFSIZE, MAXREWRITE, REQURI_LEN, CAPTURE_LEN.
# Example: SMALL_OPTS = -DBUFSIZE=8030 -DMAXREWRITE=1030 -DSYSTEM_MAXCONN=1024
SMALL_OPTS =

#### Debug settings
# You can enable debugging on specific code parts by setting DEBUG=-DDEBUG_xxx.
# Currently defined DEBUG macros include DEBUG_FULL, DEBUG_MEMORY, DEBUG_FSM,
# DEBUG_HASH and DEBUG_AUTH. Please check sources for exact meaning or do not
# use at all.
DEBUG =

#### Additional include and library dirs
# Redefine this if you want to add some special PATH to include/libs
ADDINC =
ADDLIB =

#### Specific macro definitions
# Use DEFINE=-Dxxx to set any tunable macro. Anything declared here will appear
# in the build options reported by "haproxy -vv". Use SILENT_DEFINE if you do
# not want to pollute the report with complex defines.
DEFINE =
SILENT_DEFINE =


#### CPU dependant optimizations
# Some CFLAGS are set by default depending on the target CPU. Those flags only
# feed CPU_CFLAGS, which in turn feed CFLAGS, so it is not mandatory to use
# them. You should not have to change these options. Better use CPU_CFLAGS or
# even CFLAGS instead.
CPU_CFLAGS.generic    = -O2
CPU_CFLAGS.i586       = -O2 -march=i586

#### Common CFLAGS
# These CFLAGS contain general optimization options, CPU-specific optimizations
# and debug flags. They may be overridden by some distributions which prefer to
# set all of them at once instead of playing with the CPU and DEBUG variables.
CFLAGS = $(ARCH_FLAGS) $(CPU_CFLAGS) $(DEBUG_CFLAGS)

#### Common LDFLAGS
# These LDFLAGS are used as the first "ld" options, regardless of any library
# path or any other option. They may be changed to add any linker-specific
# option at the beginning of the ld command line.
LDFLAGS = $(ARCH_FLAGS) -g

#### Target system options
# Depending on the target platform, some options are set, as well as some
# CFLAGS and LDFLAGS. The USE_* values are set to "implicit" so that they are
# not reported in the build options string. You should not have to change
# anything there.

#### Old-style REGEX library settings for compatibility with previous setups.

# to be broken using libc, so consider using pcre instead. Supported values are

# of "USE_PCRE" and "USE_STATIC_PCRE" (see build options below).
