Sources

Latest release version: 0.8.19 – Downloads

See the included INSTALL file for building instructions

To verify the signatures:

gpg --keyserver wwwkeys.pgp.net --recv-keys DDBEF0E1

You shouldn’t really trust this key without verifying its fingerprint. See it with gpg --fingerprint [email protected] and ask someone if it matches (eg. on #irssi).

gpg --verify irssi-0.8.19.tar.xz.asc

(This key is different from the one used to sign binaries of versions before 0.8.10. More gpg help can be found from GPG manual)

Development sources

Git – You can also get the development version. To check it out, run

git clone https://github.com/irssi/irssi

After check-out, you must run ./autogen.sh. It may be necessary to install additional packages. More information can be found on the wiki.
