# This GNU Makefile supports different OS and CPU combinations.
#
# You should use it this way :
# [g]make TARGET=os [CFLAGS=...] 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 :
# USE_EPOLL : enable epoll() on Linux 2.6. Automatic.

# USE_MEMORY_PROFILING : enable the memory profiler. Linux-glibc only.
# USE_LIBATOMIC : force to link with/without libatomic. Automatic.
# USE_PTHREAD_EMULATION : replace pthread's rwlocks with ours
#
# Options can be forced by specifying "USE_xxx=1" or can be disabled by using
# "USE_xxx=" (empty string). The list of enabled and disabled options for a
# given TARGET is enumerated at the end of "make help". Most of these options
# support specific xxx_CFLAGS and/or xxx_LDFLAGS that can be individually
# forced. The currently active ones for a given set of options are listed in
# "make opts USE_xxx=1 ...".
#
# Variables useful for packagers :
# CC is set to "cc" by default and is used for compilation only.
# LD is set to "cc" by default and is used for linking only.
# OPT_CFLAGS sets the default optimization level (-O2).
# CFLAGS may be used to append any flags for the C compiler.
# LDFLAGS is automatically set to -g and may be overridden.
# ARCH_FLAGS for flags common to both CC and LD. Defaults to -g.
# DEP may be cleared to ignore changes to include files during development
# DEBUG may be used to set some internal debugging options.
# ERR may be set to non-empty to pass -Werror to the compiler
# FAILFAST may be set to non-empty to pass -Wfatal-errors to the compiler
# WARN_CFLAGS overrides the default set of enabled warning options
# NOWARN_CFLAGS overrides the default set of disabled warning 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".
# EXTRA is used to force building or not building some extra tools.
# 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.
# INSTALL is set to "install" by default and is used to provide the name of
# the install binary used by the install targets and any additional
# flags.
# PREFIX is set to "/usr/local" by default and is used for installation only.

# HLUA_PREPEND_CPATH may be used to prepend a folder to Lua's default package.cpath.
#
# Other variables :
# PCRE_CONFIG : force the binary path to get pcre config (by default
# pcre-config)
# PCREDIR : force the path to libpcre.

# OT_INC : force the include path to libopentracing-c-wrapper
# OT_LIB : force the lib path to libopentracing-c-wrapper
# OT_RUNPATH : add RUNPATH for libopentracing-c-wrapper to haproxy executable
