@chapter Building and Installing

Heimdal uses GNU Autoconf to configure for specific hosts, and GNU
Automake to manage makefiles. If this is new to you, the short
instruction is to run the @code{configure} script in the top level
directory, and when that finishes @code{make}.

If you want to build the distribution in a different directory from the
source directory, you will need a make that implements VPATH correctly,
such as GNU make.

You will need to build the distribution:

@itemize @bullet
@item
A compiler that supports a ``loose'' ANSI C mode, such as @code{gcc}.
@item
lex or flex
@item
awk
@item
yacc or bison
@item
a socket library
@item
NDBM or Berkeley DB for building the server side.
@end itemize

When everything is built, you can install by doing @kbd{make
install}. The default location for installation is @file{/usr/heimdal},
but this can be changed by running @code{configure} with
@samp{--prefix=/some/other/place}.

If you need to change the default behaviour, configure understands the
following options:

@table @asis
@item @kbd{--without-berkeley-db}
DB is preferred before NDBM, but if you for some reason want to use NDBM
instead, you can use this option.

@item @kbd{--with-krb4=@file{dir}}
Gives the location of Kerberos 4 libraries and headers. This enables
Kerberos 4 support in the applications (telnet, rsh, popper, etc) and
the KDC. It is automatically found if present under
@file{/usr/athena}.  If you keep libraries and headers in different
places, you can instead give the path to each with the
@kbd{--with-krb4-lib=@file{dir}}, and
@kbd{--with-krb4-include=@file{dir}} options.

You will need a fairly recent version of our Kerberos 4 distribution for
@code{rshd} and @code{popper} to support version 4 clients.

@item @kbd{--enable-dce}
Enables support for getting DCE credentials and tokens.  See the README
files in @file{appl/dceutils} for more information.

@item @kbd{--disable-otp}
By default some of the application programs will build with support for
one-time passwords (OTP).  Use this option to disable that support.

@item @kbd{--enable-osfc2}
Enable some C2 support for OSF/Digital Unix/Tru64.  Use this option if
you are running your OSF operating system in C2 mode.

@item @kbd{--with-readline=@file{dir}}
Gives the path for the GNU Readline library, which will be used in some
programs. If no readline library is found, the (simpler) editline
library will be used instead.

@item @kbd{--with-hesiod=@file{dir}}
Enables hesiod support in push.

@item @kbd{--enable-netinfo}
Add support for using netinfo to lookup configuration information.
Probably only useful (and working) on NextStep/Mac OS X.

@item @kbd{--without-ipv6}
Disable the IPv6 support.

@item @kbd{--with-openldap}
Compile Heimdal with support for storing the database in LDAP.  Requires
OpenLDAP @url{http://www.openldap.org}.  See
@url{http://www.padl.com/Research/Heimdal.html} for more information.

@item @kbd{--enable-bigendian}
@item @kbd{--enable-littleendian}
Normally, the build process will figure out by itself if the machine is
big or little endian.  It might fail in some cases when
cross-compiling.  If it does fail to figure it out, use the relevant of
these two options.

@item @kbd{--with-mips-abi=@var{abi}}
On Irix there are three different ABIs that can be used (@samp{32},
@samp{n32}, or @samp{64}).  This option allows you to override the
automatic selection.

@item @kbd{--disable-mmap}
Do not use the mmap system call.  Normally, configure detects if there
is a working mmap and it is only used if there is one.  Only try this
option if it fails to work anyhow.
