# The default target of this Makefile is...
all:

include config/utilities.mak

# Define V to have a more verbose compile.
#
# Define O to save output files in a separate directory.
#
# Define ARCH as name of target architecture if you want cross-builds.
#
# Define CROSS_COMPILE as prefix name of compiler if you want cross-builds.
#
# Define NO_LIBPERL to disable perl script extension.
#
# Define NO_LIBPYTHON to disable python script extension.
#
# Define PYTHON to point to the python binary if the default
# `python' is not correct; for example: PYTHON=python2
#
# Define PYTHON_CONFIG to point to the python-config binary if
# the default `$(PYTHON)-config' is not correct.
#
# Define ASCIIDOC8 if you want to format documentation with AsciiDoc 8
#
# Define DOCBOOK_XSL_172 if you want to format man pages with DocBook XSL v1.72.
#
# Define LDFLAGS=-static to build a static binary.
#
# Define EXTRA_CFLAGS=-m64 or EXTRA_CFLAGS=-m32 as appropriate for cross-builds.
#
# Define NO_DWARF if you do not want debug-info analysis feature at all.
#
# Define WERROR=0 to disable treating any warnings as errors.
#
# Define NO_NEWT if you do not want TUI support.
#
# Define NO_GTK2 if you do not want GTK+ GUI support.
#
# Define NO_DEMANGLE if you do not want C++ symbol demangling.
#
# Define NO_LIBELF if you do not want libelf dependency (e.g. cross-builds)
#
# Define NO_LIBUNWIND if you do not want libunwind dependency for dwarf
# backtrace post unwind.
#
# Define NO_BACKTRACE if you do not want stack backtrace debug feature
#
# Define NO_LIBNUMA if you do not want numa perf benchmark
