Re: xboard 4.9.1 + gnuchess 6.7.2 don't work together

[Antonio Ceballos]

Hi Frank,

Thanks for your report. I think that the problem comes from the way GNU Chess is

invoked.

When you want to run it from XBoard, you must use the --xboard flag. The manual

of GNU Chess (info gnuchess) includes a couple of examples that show how to run

XBoard from the command line specifying GNU Chess as the first chess engine.

For instance:

xboard -fcp 'gnuchess --xboard'

If you just simply type

xboard -fcp 'gnuchess'

the interaction between both programs will not work.

The way XBoard invoked GNU Chess can be seen in xboard.debug. You should see

something like:

StartChildProcess (dir=".") gnuchess --xboard

In your attachment, the --xboard flag is missing.

Please let me know if this is of help to solve the problem.

Regards,

Antonio

Hello,

Xboard 4.9.1 doesn't work with GNU Chess 6.7.2 (archlinux machine).
If I'm white, it just makes one move and then after my second move it does nothing.
I've asked Xboard (bug-xboard@gnu.org) about this problem but they say, it's a GNU Chess problem.

So I don't know. Somehow the interaction between the two programs doesn't work?

I've attached the debug file:`xboard -debug`
