Irssi installation instructions ------------------------------- To compile irssi you need: - glib-2.6 or greater - pkg-config - openssl (for ssl support) - perl-5.005 or greater (for perl support) For most people, this should work just fine: ./configure make su make install (not _really_ required except for perl support) You may want to give some parameters to configure, here's the most commonly used ones: --prefix - Specifies the path where irssi will be installed. YES, you can install irssi WITHOUT ROOT permissions by using --prefix=/home/dir --with-proxy - Build the irssi proxy (see startup-HOWTO). --enable-ipv6 - Enable IPv6 support. If you want irssi to prefer IPv6 for hosts that have both v4 and v6 addresses, use /SET resolve_prefer_ipv6 ON. You can also override this with /SERVER -4 or -6 options. If ncurses is installed in a non-standard path you can specify it with --with-ncurses=/path. If anything else is in non-standard path, you can just give the paths in CPPFLAGS and LIBS environment variable, eg.: CPPFLAGS=-I/opt/openssl/include LDFLAGS=-L/opt/openssl/lib ./configure Irssi doesn't really need curses anymore, by default it uses terminfo/termcap directly. The functions for using terminfo/termcap however are usually only in curses library, some systems use libtermcap as well. If you want to use only curses calls for some reason, use --without-terminfo. Perl problems ------------- Perl support generates most of the problems. There's quite a many things that can go wrong: - Compiling fails if you compile irssi with GCC in a system that has perl compiled with some other C compiler. Very common problem with non-Linux/BSD systems. You'll need to edit src/perl/*/Makefile files and remove the parameters that gcc doesn't like. Mostly you'll just need to keep the -I and -D parameters and add -fPIC. - If there's any weird crashing at startup, you might have older irssi's perl libraries installed somewhere, and you should remove those. - Dynamic libraries don't want to work with some systems, so if your system complains about some missing symbol in Irssi.so file, configure irssi with --with-perl-staticlib option (NOT same as --with-perl=static). - If configure complains that it doesn't find some perl stuff, you're probably missing libperl.so or libperl.a. In debian, you'll need to do apt-get install libperl-dev You can verify that the perl module is loaded and working with "/LOAD" command. It should print something like: Module Type Submodules ... perl static core fe
