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
