 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)

configure options

  --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.

  --with-perl=static

  Build Perl support statically to irssi binary
  (default is to build a module)

  --with-perl-lib=[site|vendor|DIR]

  Specify installation dir for
  Perl libraries. Site is the default (usually
  /usr/local/lib/perl/...), vendor uses the path
  where the base of the perl is installed
  (/usr/lib/perl/...), or DIR specifies exactly
  where you want to install it.

  --without-perl

  Disable Perl support

  --with-socks

  Build with socks library

  --with-bot

  Build irssi-bot

  --without-textui

  Build without text frontend

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
