As of hybrid-4, the distribution uses GNU autoconf instead of the old
Config script. The Makefile has also been updated to include CFLAGS
defines for popular modern OSes.
Read the NEWS file to find out about the exciting new features in
this version. Other good reads are BUGS, doc/ircd.conf.example, and
Run the configure script. It will create include/setup.h and the
Makefiles to match your system. In ircd-ratbox, the paths are now handled
with the --prefix option to configure, not in config.h.
/usr/local/ircd is the default if no prefix is specified.
./configure --prefix="/usr/local/ircd"
Note: There are some special optional parameters to the configure
script that some admins may wish to use.
--enable-kqueue - Use the superior kqueue(2) system call as
opposed to the default poll(2). This is currently only available
on FreeBSD 4.1 or higher.
--enable-devpoll - Enable the superior /dev/poll support on
Solaris. Linux /dev/poll is broken and will not work with this
--enable-epoll - Enable the superior Linux Edge-Triggered Polling
system. This is currently only available on 2.5 Linux kernel
versions or later.
--enable-openssl - Enable the openssl dependent crypto functions.
This will allow CHALLENGE to work and encrypted links. On systems
where the configure script can automatically detect OpenSSL, this
option is not necessary. If configure cannot find OpenSSL, you
must specify a path with this option
--enable-ipv6 - Enable IPv6 support.
--enable-assert[=OPTION] - Enable some debugging code. OPTION is
either 'soft' or 'hard' (default: hard). 'hard' should never be
used on production servers as it may generate unnecessary cores.
'soft' prevents cores from being generated but still imposes some
additional load.
--enable-small-net - Tunes the server for smaller networks by
reducing the startup memory footprint. This should really only be
used for *small* networks, as this tends to be a performance hit
on larger networks.
--with-nicklen=LENGTH - Sets the maximum NICK length. Note that
this must be consistent across your entire network.
make should build ircd.
make install will install the server, modules, and tools in the
the prefix specified when configure was run.
If you wish to enable the user log, oper log, and failed oper log,
issue these commands at the shell prompt (in the prefix directory)
$ touch logs/userlog
$ touch logs/operlog
$ touch logs/foperlog
Note: If you use different names in ircd.conf, you must 'touch' the
specific names.
Send Check or Money Order to... just kidding! You're on your own for
support. Try asking other ircd-ratbox admins on EFnet if you can't fix it
yourself. If you do fix anything, however, please send context or unified
diffs to so the fixes can be incorporated into
the next release of ircd-hybrid. If ratbox crashes on you, PLEASE contact ASAP with a backtrace of the core.

Older FreeBSD machines sometimes have the obsolete ports version of
OpenSSL libcrypto in /usr/local/lib. When configure is used with
--enable-openssl, and libintl is detected in /usr/local/lib, the
/usr/local/lib directory will be searched BEFORE the system /usr/lib for
libraries by the linker. The linker may try to link to the old
/usr/local/lib libcrypto instead of the system /usr/lib libcrypto. Some
older versions may cause error messages similar to the following:
gcc -g -O2 -DIRCD_PREFIX=\"/home/wcampbel/ircd\" -Wl,-export-dynamic

*** Error code 1
If this is the case, you may need to rerun configure without the
--enable-openssl option, manually edit src/Makefile and modules/Makefile
to put -L/usr/lib before the -L/usr/local/lib in LDFLAGS, or remove the
old OpenSSL from /usr/local, and recompile all applications that use
libcrypto to use the system one.
