Just that! My Raspi 3 was running twisterd for years. As I lost the system image, I did not succeed to recompile it. This stuff needs more than a simple fork. Is there nobody with the required skills willing to maintain Twister?

Twister is dead in several ways. Glad to see the Fediverse grow and flourish. It's not P2P but it's decentralized and better than all commercial social networks. Lot of activists, media, scientists, universities and even German authorities are using it.

compilation still possible on Ubuntu 22.04 and Debian 12, I'm using first one build for Ubuntu 23.10 and it works well.

anyway in the official branch someone pushed updates for LTS libboost versions pre-compiled binaries (amd64 and sometimes arm) also attached in TA Edition releases https://github.com/twisterarmy/twister-core/releases/tag/twisterarmy-1.3

[RealVegOs]

It worked on Devuan (forgot the version, perhaps 4) for me, but not on Debian 12. The precompiled TA Edition twisterd runs on Debian 12. Just tested. THX!

[d47081]

maybe I forgot and just copied 1.3 version for debian to deploy node faster

if nobody push updates for next LTS I'll try to make those fixes. anyway, glad this release was useful for you it also includes additional DNS resolver to make new nodes connectable, because seed2.twister.net.co does not work time to time.

new users also can connect to the peers manually using following page: https://twisterarmy.github.io/network

btw, twister-html TA edition contain additional templates and UI features e.g. build-in posts translation (configurable)

@RealVegOs could you please try to recompile twister-core with this update 9a0d8cb79f3f901ab9a2c915f97d05e03bfa98bd

it works for me on Debian 12, just my Ubuntu 23.10 build have modified boost libraries to make the test.

TA branch already contain this update, and I've sent PR to official repo https://github.com/miguelfreitas/twister-core/pull/463

[RealVegOs]

THX much! Compiled and runs. I used this: ./autotool.sh ./configure --with-boost-libdir=/usr/lib/x86_64-linux-gnu/ make
