Installation (Unix)
===================
The S-Lang library is required to build slrn. If you do not have a
recent version of it installed on your system (2.1.x is needed for
full features --- Version 1.x in not supported), you need to build it
before you can compile slrn. S-Lang is freely available from
<http://www.jedsoft.org/slang/>.
*** NOTE ***
This version of slrn also requires that the S-Lang library be
*fully* installed. This means that the modules as well as the slsh
library files must be installed. Installing S-Lang from source will
automatically accomplish this. However, many linux systems
separate these components out into separate packages. If you will
be using your distribution's version of S-Lang, then you will also
need to install the other components. On debian, it is sufficient
to install slsh:
apt-get install slsh
A similar action may be required for other distributions.
Slrn uses the GNU autoconf package that makes the installation quite
simple. Assuming that the S-Lang library is installed in a standard
location, e.g., under /usr/local, executing
./configure
make
make install
is enough to configure, build and install slrn. All needed
information will be determined automatically. If you have the S-Lang
library installed in a non-standard directory or if you wish to
install slrn somewhere other than under /usr/local, then you will need
to use the --prefix or --with-slang configure options, e.g.,
./configure --prefix=/home/bob --with-slang=/opt
will install the slrn executable in /home/bob/bin/ and use the S-Lang
library intalled under /opt.
The configure script supports a number of options listed below. Especially,
you need to specify --with-slrnpull if you plan to use slrnpull.
--prefix=PREFIX
Set PREFIX to the base directory where the architecture-independent part
of slrn shall be installed.
Default: /usr/local
--with-slanglib=DIR
The location of the S-Lang library (libslang.so)
--with-slanginc=DIR
The location of the S-Lang header file slang.h.
--with-slang=DIR
Using this option is equivalent to the pair of options
`--with-slanglib=DIR/lib --with-slanginc=DIR/include'
--with-ssl[=DIR]
Include support for connections via SSL, using the OpenSSL library.
You need to set DIR to the place where OpenSSL is installed.
--with-gnutls[=DIR]
Include support for connections via SSL, using the GNU TLS library and
its OpenSSL compatibility layer.
USE WITH CARE: GNU TLS is still under heavy development and slrn's
support for it is untested.
--with-uu[=DIR]
This option tells slrn to use the uudeview library for decoding
uuencoded articles instead of its builtin routines.
--with-canlock[=DIR]
Tells slrn to make use of the canlock library (needed to use
"Cancel-Locks" when posting, see <http://cssri.meowing.net/>).
USE WITH CARE: libcanlock does not seem to be fully mature yet; also,
the library does not have an installation routine. When installing it by
hand, be careful to copy only canlock.h (and none of the other header
files that come with it) into your system include directory.
--with-slrnpull
Build slrnpull and enable support for it in slrn.
--enable-setgid-code
Enables code that allows you to run slrnpull as an unpriviledged user.
See doc/slrnpull/setgid.txt for details.
--disable-nntp
Don't include NNTP support.
--enable-spool
Include support for reading news directly from a news spool (enabled
implicitly by --with-slrnpull).
--enable-inews
Enable inews support (enabled implicitly by --enable-force-inews).
--enable-force-inews
This option enforces the use of inews for posting. Without this option,
the user is allowed to choose a posting method.
--enable-strict-from
This option completely disallows the user to configure his "From" header
line. All attempts to change the startup values that were retrieved
from the system for "hostname", "username" and "realname" will fail.
make_from_string_hook does not get executed; manually added "From"
headers are rejected when posting.
--disable-charmap
Disables the mapping between ISO-Latin and native character sets like
isolatin, ibm850, NeXT and koi8
--disable-spoilers
Disable the special behaviour if slrn encounters a linefeed character.
--disable-emph-text
Turn off the coloring of *emphasized* _text_.
--disable-gen-mid
This prevents slrn from generating its own Message-IDs.
--enable-mid-cache
Make slrn cache Message-IDs during a session and use them to eliminate
cross-posts. This should not be necessary if your server supports Xref
in its overview database.
--disable-fake-refs
Don't use the In-Reply-To header for building the thread tree if no
References header is available.
--enable-grouplens
Enable grouplens support. Since the grouplens project seems to be dead,
you probably won't need this. See README.GroupLens for further
information.
--enable-warnings
If using gcc, enable the output of warnings during compilation.
--enable-profiling
If using gcc, the slrn binary will write profile data to gmon.out.
Never use this option when compiling slrn for production use!
--exec-prefix=EPREFIX
Set EPREFIX to the base directory where the architecture-dependent part
of slrn will be installed.
Default: PREFIX [/usr/local]
--bindir=BINDIR
The directory where the slrn executable will be put.
Default: EPREFIX/bin [/usr/local/bin]
--mandir=MANDIR
The place where man pages will be installed.
Default: PREFIX/man [/usr/local/man]
--datadir=DATADIR
Architecture-independent read-only files such as slang macros.
Default: PREFIX/share/slrn [/usr/local/share/slrn]
--sysconfdir=SYSCONFDIR
Directory for global configuration files (like slrn.rc).
Default: PREFIX/etc [/usr/local/etc]
--with-docdir=DIR
The directory where slrn's documentation is placed.
Default: PREFIX/share/doc/slrn [/usr/local/share/doc/slrn]
--with-libdir=LIBDIR
Directory where slrn will expect the global newsgroups description file.
Default: PREFIX/lib/slrn [/usr/local/lib/slrn]
Some rarely used compile-time options are not under autoconf control. You
need to edit src/slrnfeat.h manually before running "make" to change them.
