Hi All, So I tried to create a github repo : https://github.com/2005m/RLibTorrent
As suggested by Ralf, I started on Ubuntu and installed libtorrent. I have few issues When I do R CMD build RLibTorrent and then R CMD check RLibTorrent_1.0.tar.gz , I get an error: * using log directory ‘/home/morgan/Documents/Packages/RLibTorrent.Rcheck’ * using R version 3.5.1 (2018-07-02) * using platform: x86_64-pc-linux-gnu (64-bit) * using session charset: UTF-8 * checking for file ‘RLibTorrent/DESCRIPTION’ ...

Google it but it i didn't help me solve it, because I didn't understand the explanation or the proposed solution was not working for me. Any idea what I am doing wrong?
