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 ...
#
# By default the detailed commands are hidden for a cleaner output, but you may
# see them by appending "V=1" to the make command.
#

#    generic, native, i586, i686, ultrasparc, custom

#### 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 32, 64, x86_64, i386, i486, i586 and i686 are understood.

#### 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

#### 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, DEBUG_AUTH, DEBUG_SPOE, DEBUG_UAF and DEBUG_THREAD. Please check
# sources for exact meaning or do not use at all.

#### 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.
# The following settings might be of interest when SSL is enabled :
#   LISTEN_DEFAULT_CIPHERS is a cipher suite string used to set the default SSL
#           ciphers on "bind" lines instead of using OpenSSL's defaults.
#   CONNECT_DEFAULT_CIPHERS is a cipher suite string used to set the default
#           SSL ciphers on "server" lines instead of using OpenSSL's defaults.
