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 ...
#
# When in doubt, invoke help, possibly with a known target :
#   [g]make help
#   [g]make help TARGET=linux-glibc
#
# By default the detailed commands are hidden for a cleaner output, but you may
# see them by appending "V=1" to the make command.
#
# Valid USE_* options are enumerated in the "use_opts" variable and are listed
# below. Most of them are automatically set by the TARGET, others have to be
# explicitly specified :

#    linux-glibc, linux-glibc-legacy, linux-musl, solaris, freebsd, dragonfly,
#    openbsd, netbsd, cygwin, haiku, aix51, aix52, aix72-gcc, osx, generic,

#    a53, a72, armv81, armv8-auto
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 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

# without appearing here. Currently defined DEBUG macros include DEBUG_FULL,
# DEBUG_MEM_STATS, DEBUG_DONT_SHARE_POOLS, DEBUG_FD,
# DEBUG_NO_POOLS, DEBUG_FAIL_ALLOC, DEBUG_STRICT_NOCRASH, DEBUG_HPACK,

# 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.
