Description: The R plugin for TeXmacs did not install a tm_r executable in it's plugins directory. This causes R sessions to show "Busy..." and "R]" and not allow the user to evaluate any code.

The R plugin developer for TeXmacs informed me of the problem in the comments thread to this blog post:

Additional info:

This is for TeXmacs package version 1.99.5-2.

Comment from the R plugin maintainer when investigating the Manjaro installation on my operating system (Manjaro):

"Indeed R doesn’t work under TeXmacs. In my installation, this is because for some reason the interface between R and TeXmacs, called tm_r, isn’t installed. It should be under /usr/lib/TeXmacs/bin
I’m not sure why. I was trying to install TeXmacs from the source, but I was having problems (with guile). Do you know how to recompile the TeXmacs package in manjaro?

OK, actually I don’t need to compile all of TeXmacs, just tm_r.
It seems there’s a problem with the compilation, which can be solved by adding a line
#define HAVE_PTY_H
to the source code, or compile with -D HAVE_PTY_H
Maybe I should tell the package maintainer.

So, you can compile that file in the TeXmacs source and put it in said directory (in the source directory go to plugins/r and type make)."

Steps to reproduce:

1. open TeXmacs.
2. Click the Sessions icon (it looks like a computer monitor).
3. Select R from the dropdown menu.
4. A session textblock should appear "Busy..."
5. A broken session prompt should appear "R]"
