### Variable overrides

# You can change many aspects of the build behaviour without modifying this
# make file simply by setting environment variables.
#
# Dependencies and features are auto-detected, but can be overridden:
#
# OPENSSL_BASE  Prefix of OpenSSL library and headers to build against
# LIBEVENT_BASE Prefix of libevent library and headers to build against
# LIBPCAP_BASE  Prefix of libpcap library and headers to build against
# LIBNET_BASE   Prefix of libnet library and headers to build against
# LIBJSON_BASE  Prefix of libjson-c library and headers to build against
# CHECK_BASE    Prefix of check library and headers to build against (optional)
# PKGCONFIG     Name/path of pkg-config program to use for auto-detection
# PCFLAGS       Additional pkg-config flags
# XNU_VERSION   Version of included XNU headers to build against (OS X only)
# FEATURES      Enable optional or force-enable undetected features (see below)
#
# Where and how to install to:
#
# PREFIX        Prefix to install under (default /usr/local)
# DESTDIR       Destination root under which prefix is located (default /)
# BINDIR        Path to user executables (default $(PREFIX)/bin)
# MANDIR        Path to man section dirs (default $(PREFIX)/share/man)
# SYSCONFDIR    Path to system configuration (default $(PREFIX)/etc)
# INSTALLUID    UID to use for installed files if installing as root
# INSTALLGID    GID to use for installed files if installing as root
#
# Standard compiler variables are respected, e.g.:
#
# CC            Compiler, e.g. for cross-compiling, ccache or ccc-analyzer
# CFLAGS        Additional compiler flags, e.g. optimization flags
# CPPFLAGS      Additional pre-processor flags
# LDFLAGS       Additional linker flags
# LIBS          Additional libraries to link against
# SOURCE_DATE_EPOCH     Set to epoch time to make the build reproducible
#
# On macOS, the following build environment variables are respected:
#
# DEVELOPER_DIR         Override Xcode Command Line Developer Tools directory
# MACOSX_VERSION_MIN    Minimal version of macOS to target, e.g. 10.11
# SDK                   SDK name to build against, e.g. macosx, macosx10.11
#
# Examples:
#
# Build against custom installed libraries under /opt:
# % OPENSSL_BASE=/opt/openssl LIBEVENT_BASE=/opt/libevent make
#
# Create a statically linked binary:
# % PCFLAGS='--static' CFLAGS='-static' LDFLAGS='-static' make
#
# Build against musl libc that needs an additional library for fts(3):
# % LIBS='-lfts' make
#
# Build a macOS binary for El Capitan using the default SDK from Xcode 7.3.1:
# % MACOSX_VERSION_MIN=10.11 DEVELOPER_DIR=/Applications/Xcode-7.3.1.app/Contents/Developer make


### Mirroring

# Define to disable support for mirroring connection content as emulated
# packets to a network interface (-I/-T options).  Doing so will remove the
# dependency on both libnet and libpcap.  Use this for constrained environments
# or on platforms without usable libnet/libpcap.  Logging connection content to
# PCAP files will remain fully functional (-X/-Y/-y options) as it does not
# make use of libnet and libpcap.
#FEATURES+=	-DWITHOUT_MIRROR

### Content filtering
# Define to enable HTTP content filtering. This feature requires json-c library.
# File with filtering rules can be applied with -J option. Example:
# {"rules" : [
# { "id"      : "1",
#   "action"  : "drop",
#   "method"  : ["GET"],
#   "url"     : ["1.example.com/", "2.example.com/*]",
#   "content" : ["text/html", "image/*"]}
# ], "default_action" : "pass", "http_deny_tmpl" : "<h2>%s</h2>" }
#FEATURES+=	-DWITH_CONTENT_FILTER


### OpenSSL tweaking

# Define to enable support for SSLv2.
# Default since 0.4.9 is to disable SSLv2 entirely even if OpenSSL supports it,
# since there are servers that are not compatible with SSLv2 Client Hello
# messages.  If you build in SSLv2 support, you can disable it at runtime using
# -R ssl2 to get the same result as not building in SSLv2 support at all.
#FEATURES+=	-DWITH_SSLV2


### Debugging

# These flags are added to CFLAGS iff building from a git repo.
DEBUG_CFLAGS?=	-g
#DEBUG_CFLAGS+=	-Werror

# Define to remove false positives when debugging memory allocation.
# Note that you probably want to build OpenSSL with -DPURIFY too.
#FEATURES+=	-DPURIFY

# Define to add proxy state machine debugging; dump state in debug mode.
#FEATURES+=	-DDEBUG_PROXY

# Define to add certificate debugging; dump all certificates in debug mode.
#FEATURES+=	-DDEBUG_CERTIFICATE

# Define to add SSL session cache debugging; dump all sessions in debug mode.
#FEATURES+=	-DDEBUG_SESSION_CACHE

# Define to add debugging of sslsplit's own ClientHello message parser.
#FEATURES+=	-DDEBUG_CLIENTHELLO_PARSER

# Define to add thread debugging; dump thread state when choosing a thread.
#FEATURES+=	-DDEBUG_THREAD

# Define to add privilege separation server event loop debugging.
#FEATURES+=	-DDEBUG_PRIVSEP_SERVER

# Define to add diagnostic output for debugging option parsing.
#FEATURES+=	-DDEBUG_OPTS

# When debugging OpenSSL related issues, make sure you use a debug build of
# OpenSSL and consider enabling its debugging options -DREF_PRINT -DREF_CHECK
# for debugging reference counting of OpenSSL objects and/or
# -DPURIFY for using valgrind and similar tools.


### Mac OS X header selection

# First, try to use the exact XNU version reported by the kernel.  If they
# are not available, try to look up a suitable XNU version that we have
# headers for based on the OS X release reported by sw_vers.  Then as a last
# resort, fall back to the latest version of XNU that we have headers for,
# which may or may not work, depending on if there were API or ABI changes
# in the DIOCNATLOOK ioctl interface to the NAT state table in the kernel.
#
# Note that you can override the XNU headers used by defining XNU_VERSION.
