Can't connect to rtorrent. the mentor buffer is empty!

[LinArcX]

rtorrent is installed on my machine(void Linux) and I can use it from the terminal. here's my .rtorrrent.rc file:

directory.default.set = /mnt/E/rtorrent/download
session.path.set = ~/rtorrent/.session

schedule2 = watch_directory,5,5,load.start=/mnt/E/rtorrent/watch/*.torrent
dht.mode.set = auto
dht.port.set = 6881
protocol.pex.set= yes

scgi_local = ~/.rtorrent-rpc.socket
encoding.add = utf8

And here's my init.el file:

(use-package mentor)

(setq mentor-rtorrent-download-directory "/mnt/E/rtorrent/download")
(setq mentor-rtorrent-keep-session t)

When I run Mentor in Emacs, I just see an empty buffer. (in rterminal itself, I have bunch of torrent files)

Even if i try to add this line to my init.el:
(setq mentor-rtorrent-external-rpc "~/.rtorrent-rpc.socket")

I'll get these error:

Debugger entered--Lisp error: (file-missing "make client process failed" "No such file or directory" :name "scgi" :buffer #<buffer  *scgi /.rtorrent-rpc.socket*> :remote "/.rtorrent-rpc.socket")

I can confirm I get the same issue

Me too, both on my desktop and laptop, which are both running Gentoo.

I get the same issue on Arch.

The problem seems to be that the mentor-rtorrent-create-conf function creates a configuration file using the following two paths:

mentor/mentor.el

Lines 526 to 527 in ed42ae8

	(rpc (expand-file-name "rtorrent.rpc" mentor-home-dir))
	(conf (expand-file-name "rtorrent.rc" mentor-home-dir)))

Normally in ~/.emacs.d/mentor/rtorrent.rc. The path included inside that file, ~/.emacs.d/mentor/rtorrent.rpc, does not exist on my machine, and causes an error. If I manually touch it, I get no error, but the buffer is still empty.

Turns out my problem was that the guix build of rtorrent did not have support for xmlrpc. The version on the Arch package manager did.

@nameiwillforget On Gentoo, make sure you have installed rtorrent with the xmlrpc USE flag enabled (see https://packages.gentoo.org/packages/net-p2p/rtorrent).
