Irssi installation instructions ------------------------------- To compile irssi you need: - glib-2.6 or greater - pkg-config - openssl (for ssl support) - perl-5.6 or greater (for perl support) For most people, this should work just fine: ./autogen.sh (for people who just cloned the repository) ./configure (if this script already exists, skip ./autogen.sh) 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). --disable-ssl Disable SSL support. --with-perl=[yes|no|module] Enable Perl support yes enable builtin (default) no disable module enable as module --with-perl-lib=[site|vendor|DIR] Specify installation dir for Perl libraries site install in dir for site-specific modules (default) vendor install in dir for vendor-specific modules DIR install in DIR --with-socks Build with socks library --with-bot Build irssi-bot --without-textui Build without text frontend If anything 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 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 - For unprivileged home directory installations, using the local::lib CPAN module is recommended. Read its docs, bootstrap it if needed, ensure that the environment variables are set before running the configure script, and append "--with-perl-lib=site" to the configure parameters to use it. 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 System specific notes --------------------- Cygwin Getting perl scripting to work needs a few things: - configure with --with-perl-staticlib - libperl.dll is required in linking and running irssi, it's normally located somewhere around /usr/lib/perl5/5.6.1/cygwin/CORE/libperl5_6_1.dll copy it to eg. /usr/bin/libperl.dll - -DUSEIMPORTLIB is needed to be defined while compiling src/perl directory. It doesn't hurt to be defined everywhere, so configure irssi with: CFLAGS='-DUSEIMPORTLIB' ./configure --with-perl-staticlib
