### 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
# 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 /)
# MANDIR Subdir of PREFIX that contains man section dirs
# 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
#
# You can e.g. create a statically linked binary by running:
# % PCFLAGS='--static' CFLAGS='-static' LDFLAGS='-static' make
### 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
# Define to make SSLsplit set a session id context in server mode.
#FEATURES+= -DUSE_SSL_SESSION_ID_CONTEXT
### 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
# 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.
