Anyway we can make the non supported variant error for an engine, non fatal for
xboard?
What error exactly do you mean? You should not be able to switch to a
variant the current first engine does not support. The second engine is
only woken up when you hit Two Machines. But this gives me a non-fatal
error popup, saying the second engine does not support the variant.
(Minor bug: the Two Macines menu remains check-marked after this, in
addition to Edit Game, which is the mode it leaves me in.)
When XBoard is set for 'normal', and I load HaChu (which does not play
'normal') as first engine, it does not give me an error. (Just a
rejection of my move by HaChu when I start playing, which probably also
should be considered a bug.) I did not get anything fatal.
I guess it should have switched to a variant that HaChu does play (the
first one of its variants-feature list) when it was loaded as first
engine. XBoard already does that when you would load HaChu from the
command line without explicit -variant specification:
xboard -fcp hachu
would start up in Chu Shogi (and the second engine would also be hachu!).
OTOH, when an engine does not support 'normal', it was sort of expected
you would install it with a -variant option that would specify a variant
it does play. It would then appear in the Load Engine listbox as hachu
(chu) (say). In this case it would auomatically switch variant on
loading it, and there would not be a problem.
