Hello, in Coq 8.5 the protocol between CoqIDE and coqtop changed and
also how coqtop is started.  This is an example of the command line
CoqIDE uses:

 coqtop -main-channel stdfds -control-channel 127.0.0.1:48310 -ideslave

IIRC the control channel is optional, but you must tell coqtop how to
connect to the UI (main channel), either using a pipe as in the example
or using a socket (as for the control channel, HOST:PORT).

I'll look at the error message and try to make it more informative.

To get more info about the new protocol used by CoqIDE:

  coqtop -toploop coqidetop --help-XML-protocol

Last, the main loop of coqtop can now be changed by providing a plugin
in the toploop/ directory.  CoqIDE makes no exception (if you install
coq system wide you find coqidetop.cmxs inside this directory).
If you are interested in developing a UI for Coq, this gives you the
freedom to choose the communication protocol you prefer.

There is no documentation, so feel free to ask.

Best,
