Leafnode is an NNTP proxy news server which you can use to quite conveniently keep your un/read status synced over several newsreaders on different devices.

You can install Leafnode on your uberspace using linuxbrew, which is a fork of the well-known homebrew for mac.

Installing linuxbrew

The uberspace-wiki already holds most of the steps neccessary to install linuxbrew, i.e.:

$ git clone https://github.com/Homebrew/linuxbrew.git ~/.linuxbrew
$ echo "PATH=\"$HOME/.linuxbrew/bin:$PATH\"" >> ~/.bashrc
$ echo "MANPATH=\"$HOME/.linuxbrew/share/man:$MANPATH\"" >> ~/.bashrc
$ echo "INFOPATH=\"$HOME/.linuxbrew/share/info:$INFOPATH\"" >> ~/.bashrc

Do not forget to source your .bashrc-file or just logout and login again.

Installing Leafnode version 1.11.10

does NOT run on uberspace, though. Install Leafnode-2 instead!

So far, so good, but if you want to install leafnode, it will throw the following error-msg at you:

$ brew install leafnode
==> Installing dependencies for leafnode: bzip2, pcre
==> Installing leafnode dependency: bzip2
Error: bzip2 cannot be built with any available compilers.
To install this formula, you may need to:
brew install gcc

This leads to a kind of recursive situation, though:

$ brew install gcc
==> Installing dependencies for gcc: gmp, mpfr, libmpc, isl, cloog
==> Installing gcc dependency: gmp
Error: gmp cannot be built with any available compilers.
To install this formula, you may need to:
brew install gcc

Luckily, i was not the first one encountering this problem, so the solution was already there - you have to add a symlink in your .linuxbrew-directory to your gcc/g++ compiler:

$ ln -s `which gcc` ~/.linuxbrew/bin/gcc-`gcc -dumpversion |cut -d. -f1,2`
$ ln -s `which g++` ~/.linuxbrew/bin/g++-`g++ -dumpversion |cut -d. -f1,2`

Having done this, you can install leafnode without any further problems:

$ brew install leafnode

==> Installing leafnode dependency: bzip2

==> make install
/home/USER/.linuxbrew/Cellar/leafnode/1.11.10: 27 files, 820K, built in 10 seconds

Next step is to configure it properly.

 

 

Note:

You might encounter the following, GitHub related, error:

$ brew search git
git
Error: GitHub API rate limit exceeded for x.x.x.x. (But here's the good news: Authenticated requests get a higher rate limit. Check out the documentation for more details.)
Try again in 40 minutes 22 seconds, or create an personal access token:
  https://github.com/settings/tokens
and then set it as HOMEBREW_GITHUB_API_TOKEN.

To fix this, create your GitHub API token (you need to have an GitHub account for that) and add the following line to your ~/.linuxbrew/bin/brew file:

#!/bin/sh
export HOMEBREW_GITHUB_API_TOKEN=xxx
