# Generic default make file containing settings that relate to the OS or
# to selectable features within the OS. The configuration options for Exim
# itself live in Local/Makefile, which is constructed by editing src/EDITME.

# These settings are basic defaults which may be overridden, either by the
# generic OS-specific files, or by site-specific files. Do not edit this file.
# Instead, edit or create suitable OS-specific and/or site specific files.
# See the manual for details.


# MAKE_SHELL contains the name of the shell to be used for executing commands
# from the make files. Normally /bin/sh should be used.

MAKE_SHELL=/bin/sh


# BASENAME_COMMAND contains the path to the "basename" command, which varies
# from OS to OS. This is used when building the Exim monitor script only. (See
# also HOSTNAME_COMMAND.) If BASENAME_COMMAND is set to "look_for_it" then the
# script checks for /usr/bin/basename and /bin/basename, and if neither is
# found, it uses /usr/ucb/basename. This copes with Solaris 2 and Linux, both
# of which come in different versions.

BASENAME_COMMAND=/usr/bin/basename


# If you set STRIP_COMMAND to the path of the "strip" command, it will be run
# on every binary that is built. It is left unset by default, which leaves
# the binaries unstripped.

# STRIP_COMMAND=/usr/bin/strip


# Some of the following commands live in different places in different OS. We
# include them all here for generality.

CHOWN_COMMAND=/usr/bin/chown
CHGRP_COMMAND=/usr/bin/chgrp
CHMOD_COMMAND=/usr/bin/chmod
MV_COMMAND=/bin/mv
RM_COMMAND=/bin/rm
TOUCH_COMMAND=/usr/bin/touch


# Some operating systems have different ways of building libraries of
# functions. This macro defines the command to do this, defaulting to
# the "ar" command with options "cq".

AR=ar cq


# Not all operating systems have the iconv() function. Those that do have
#
# HAVE_ICONV=yes
#
# in their OS-specific Makefiles. On those that don't it is possible to
# install an independent implementation of iconv(). If you've done this,
# add "HAVE_ICONV=yes" to your Local/Makefile.


# Perl is not necessary for running Exim itself, except when EXIM_PERL
# is set to cause Perl embedding. However, some Perl utilities are provided
# for processing the logs. Perl 5 is assumed.

PERL_COMMAND=/usr/bin/perl


# CC contains the name of the C compiler to be used.

CC=gcc


# CFLAGS contains flags to be passed to the compiler. Nothing is defaulted
# here; instead each OS-dependent Makefile contains a default setting.

# CFLAGS=-O


# LFLAGS contains flags to be passed to the link editor. Nothing is defaulted
# here; instead each OS-dependent Makefile contains a default setting if one
# is needed.

# LFLAGS=


# PCRE_LIBS contains the library to be linked for PCRE

PCRE_LIBS=-lpcre2-8


# LIBS and EXTRALIBS contain library settings that are used on linking
# commands to build binaries. The OS-dependent Makefile may contain a default
# setting for LIBS, leaving EXTRALIBS available for adding further libraries
# that are required for optional extras.

# LIBS=
# EXTRALIBS=


# LIBS_EXIM and EXTRALIBS_EXIM contain library settings that are used
# only when linking the Exim binary. They are not used for other binaries.
# One possible use is for the TCP wrappers library.

# LIBS_EXIM=
# EXTRALIBS_EXIM=


# LIBS_EXIMON and EXTRALIBS_EXIMON contain library settings that are
# used only when linking the Exim monitor binary. They are not used for
# other binaries.

# The error name for quota exceeded varies among operating systems, and
# even, unfortunately, in different versions of the same operating system.
# EDQUOT was not in Sys V, but is in SPEC 1170, apparently. It was used
# in SunOS4, but got taken out for SunOS5, where ENOSPC was given if a quota
# was exceeded. However, it got put back into SunOS5 with a patch to 5.4 in
# order to comply with SPEC 1170. Thus even different patch levels of the same
# system (SunOS5) may use different numbers.
#
# If you don't have quotas or are not interested in handling quota errors
# specially, just set this variable to 0. If it is not set, it defaults to
# EDQUOT if that is defined for the OS; otherwise it defaults to ENOSPC.

# ERRNO_QUOTA=EDQUOT


# The exiwhat utility script finds all the processes running Exim, and sends
# them a SIGUSR1 signal to get them to write their status to a file. There are
# two ways in which this can be done:
#
# (1) If the OS has a command to find processes and signal them, that can be
# used. Linux has "killall"; Solaris has "pkill". (Note: "killall" on Solaris
# does something very different - and disastrous.) The following are set in the
# OS-specific Makefiles for those OS where this can be done:

# EXIWHAT_MULTIKILL_CMD=
# EXIWHAT_MULTIKILL_ARG=

# (2) For other operating systems, exiwhat calls the ps command and greps the
# output in order to find all the processes running Exim. The arguments for the
# various commands needed to do this vary from OS to OS. These defaults work on
# Solaris 2, HPUX, and IRIX. The OS-specific Makefiles have different versions
# for other systems, and you can override with your own requirements in your
# private Makefiles in the Local directory. The most commonly found
# alternatives are -ax instead of -e for the ps argument, and / instead of a
# blank before the name exim for the grep argument on systems whose ps output
# shows the full path name. The quotes for the grep argument are specified
# here so that leading white space can be used. This value should always be
# given in single quotes.

EXIWHAT_PS_CMD=/bin/ps
EXIWHAT_PS_ARG=-e
EXIWHAT_EGREP_ARG=' exim( |$$|-)'

# For both kinds of exiwhat usage, the next setting specifies the signal that
# is sent.

EXIWHAT_KILL_SIGNAL=-USR1


# IPv6 is gradually spreading more and more widely. Most operating systems seem
# to support it nowadays. If you set this option, IPv6 support will be included
# in the Exim binary. As well as the basic enabling option, there are
# parameters for include and library directories that may be needed for IPv6 on
# some systems, where the support is not yet in the standard library.

# HAVE_IPV6=YES
# IPV6_INCLUDE=-I /usr/ipv6/include
# IPV6_LIBS=-L/usr/ipv6/libs -linet6

# Exim uses the function getaddrinfo() for converting IPv6 addresses in text
# form to binary. Apparently some operating systems do not support this, or not
# correctly, and require the use of the function inet_pton() instead. The
# following setting enables this. Note, however, the inet_pton() has reduced
# functionality compared with getaddrinfo(). In particular, it does not
# recognize the percent convention for identifying scopes (interfaces) that is
# used by some operating systems.

# IPV6_USE_INET_PTON=yes

# HOSTNAME_COMMAND contains the path to the "hostname" command, which varies
# from OS to OS. This is used when building the Exim monitor script only. (See
# also BASENAME_COMMAND.) If HOSTNAME_COMMAND is set to "look_for_it" then the
# script checks for /usr/bin/hostname and /bin/hostname, and if neither is
# found, it uses /usr/ucb/basename. This copes with Solaris 2, which comes in
# different versions.

HOSTNAME_COMMAND=/bin/hostname


# INCLUDE contains arbitrary include parameters that you may need to use
# when building exim. It is added to every compile command.

# INCLUDE=-I /some/special/include-directory


# Some OS require a separate library to be quoted when linking programs that
# call name resolver functions. This can be set in LIBRESOLV, which is left
# unset here, but is set is some of the OS-specific Makefiles.

# LIBRESOLV=


# Additional libraries and include directories may be required for some
# lookup styles, e.g. LDAP or SQL. LOOKUP_LIBS is included only on the
# command for linking Exim itself, not on any auxiliary programs. You
# don't need to set LOOKUP_INCLUDE if the relevant directories are already
# specified in INCLUDE.

# LOOKUP_INCLUDE=-I /usr/local/ldap/include -I /usr/local/sql/include
# LOOKUP_LIBS=-L/usr/local/lib -lldap -llber


# RANLIB should be set to something that does nothing on systems that do not
# have the ranlib command or do not need to run it on library files.

RANLIB=ranlib


# EXIM_CHMOD is available to specify a command that is automatically applied
# to the Exim binary immediately it is compiled. (I find this useful when
# building test versions.)

EXIM_CHMOD=@true


# If you want to use local_scan() at all, the support code must be included
# by uncommenting this line.

# HAVE_LOCAL_SCAN=yes

# LOCAL_SCAN_SOURCE defines the file in which the function local_scan() is
# defined. This provides the administrator with a hook for including C code
# for scanning incoming mails. The path that is defined must be relative to
# the Exim distribution directory. For example

# LOCAL_SCAN_SOURCE=Local/local_scan.c

# A very simple example points to a template function that doesn't actually do
# any scanning, but just accepts the message.  A compilable file must be
# included in the build even if HAVE_LOCAL_SCAN is not defined.

LOCAL_SCAN_SOURCE=src/local_scan.c

# If you want to specify options for your local_scan() that can be set from
# the main Exim configuration file, you need to uncomment the following line,
# and then provide a table of options in your local_scan() source, as described
# in the reference manual.

# LOCAL_SCAN_HAS_OPTIONS=yes

# The following are all concerned with configuring the way Exim handles its
# database (hints) and other dbm files.

# Some systems require a separate library to be supplied when linking programs
# that make use of DBM library calls. This can be set in DBMLIB, which is unset
# by default, but is set in some of the OS-specific Makefiles. Setting it in
# your Local/Makefile will override any other setting.

# DBMLIB=


# When Exim is attempting to lock one of its database (hints) files, it
# applies a timeout which can be altered here.

# EXIMDB_LOCK_TIMEOUT=60


# By default, Exim uses traditional ndbm function calls to handle its indexed
# hints databases. On systems that have Berkeley db installed, this still
# works via the compatibility interface. However, by defining USE_DB you can
# make it use native db function calls.

# USE_DB=YES

# Similarly, if you are using gdbm, Exim will by default use the ndbm
# compatibility interface. However, by defining USE_GDBM you can make it
# use the native gdbm function calls.

# USE_GDBM=YES

# The following definitions are relevant only when compiling the Exim monitor
# program, which requires an X11 display. See the variable EXIM_MONITOR in
# src/EDITME for how to suppress this compilation.

# X11 contains the location of the X11 libraries and include files.

X11=/usr/X11R6

# XINCLUDE contains options for header inclusion when compiling functions
# that call X11 functions.

XINCLUDE=-I$(X11)/include

# XLFLAGS contains flags to be passed to the linker when linking the monitor.

XLFLAGS=-L$(X11)/lib

# X11_LD_LIB contains the name of the X11 library that is to be added to
# LD_LIBRARY_PATH when running the monitor program.

X11_LD_LIB=$(X11)/lib

# A modified version of the Athena TextPop module is supplied with Exim. The
# modification is to remove the "replace" part of the "search and replace"
# operation because it isn't wanted. TextPop is only one of a number of
# modules that make up the Text widget. Some antique link editors cannot handle
# the case of a replacement module for one of a set of modules. To allow
# the monitor to be linked in such cases, set the value of EXIMON_TEXTPOP
# to be empty. The search operations will then contain a useless "replace"
# option, which is untidy, but does no harm.

EXIMON_TEXTPOP=em_TextPop.o
