Charybdis INSTALL Document $Id: INSTALL 3384 2007-04-03 22:45:04Z jilles $ Copyright (c) 2001 by ircd-hybrid team Copyright (c) 2002-2004 ircd-ratbox development team Copyright (c) 2005-2008 charybdis development team ---------------------------------------------------------------------- HOW TO BUILD 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. 1. Read the NEWS file to find out about the exciting new features in this version. Other good reads are BUGS, doc/example.conf, and README.FIRST. 2. 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 option. * --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-openssl=/path/to/openssl) * --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. 3. make should build ircd. 4. make install will install the server, modules, and tools in the the prefix specified when configure was run. 5. 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. 6. If you are upgrading from Hybrid 5 or Hybrid 6, the config file has changed drastically... There is a utility to convert your old config file to the new format. In prefix/bin there is something called "convertconf". Its usage is: ./convertconf (old config file to convert) (converted file name) Convertconf will NOT convert I: lines. You must use "convertilines" for this which contains a much superior method of conversion and will group I: together under one auth {};. Once this is done, move your new config to prefix/etc/ircd.conf and EDIT IT! There are still things that need changing in the config, including the fact that classes MUST be above auth/connect blocks! 7. If you are upgrading from Hybrid 5 or Hybrid 6, the kline file has also changed... There is a utility to convert the old kline configuration file to the new format. In prefix/bin there is a program called "convertklines". Its usage is: ./convertklines (old kline.conf filename) (new kline.conf filename) (dline.conf filename). Once this is done, move the new files into the prefix/etc/ directory under their proper names. By default, the kline file is named kline.conf and the dline file is named dline.conf. ---------------------------------------------------------------------- HOW TO GET HELP 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 ircd-ratbox@lists.ratbox.org so the fixes can be incorporated into the next release of ircd-hybrid. If ratbox crashes on you, PLEASE contact ircd-ratbox@lists.ratbox.org ASAP with a backtrace of the core. DISCUSSION: There is a mailing list for discussion of ratbox issues, To subscribe, visit: http://lists.ratbox.org/cgi-bin/mailman/listinfo/ircd-ratbox ---------------------------------------------------------------------- NOTES The best way to get a backtrace of the core is to follow this sequence of instructions: 1. Change to the directory containing the core file 2. Run gdb on the binary and the core file. With an unmodified ircd-ratbox installation, an example command line is below (in the /usr/local/ircd directory) $ gdb bin/ircd ircd.core 3. At the "(gdb)" prompt, enter the command "bt" 4. Save the output of the backtrace command and send it to ircd-ratbox@lists.ratbox.org 5. Be sure to save the ircd binary, the modules, and the core file in a safe place in case the developers need to look deeper than a backtrace provides. ---------------------------------------------------------------------- OPENSSL NOTES 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 -L/usr/local/lib -o ircd blalloc.o channel.o vchannel.o class.o client.o dline_conf.o event.o fdlist.o fileio.o hash.o irc_string.o ircd.o ircdauth.o ircd_signal.o linebuf.o list.o listener.o m_error.o match.o memdebug.o modules.o motd.o mtrie_conf.o oldparse.o numeric.o packet.o parse.o res.o rsa.o restart.o s_auth.o s_bsd.o s_bsd_kqueue.o s_conf.o s_debug.o s_gline.o s_log.o s_misc.o s_serv.o s_stats.o s_user.o scache.o send.o sprintf_irc.o tools.o whowas.o lex.yy.o y.tab.o version.o -lintl -ldescrypt -lcrypto -lfl rsa.o: In function `get_randomness': /home/wcampbel/dev/ircd-ratbox/src/rsa.c(.text+0x60): undefined reference to `RAND_pseudo_bytes' /usr/local/lib/libcrypto.so: undefined reference to `ERR_load_RSAREF_strings' /usr/local/lib/libcrypto.so: undefined reference to `RSA_PKCS1_RSAref' *** 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.
