crashes when trying to perform castle (king/rook exchange)

[randcoop]

Binary package hint: knights

The Ubuntu package for Knights in Edgy (0.6-7.1ubuntu1) crashes when it encounters a castle move (invoked by moving the king two squares toward the rook).

The Debian Unstable package (0.6-7.1) does not have this bug. So the creater of the (K)Ubuntu package developed the error.

The problem with installing the Debian package is only that the Adept notifier sees the Ubuntu version of the package as an upgrade for the Debian pakage. As a result, the notifier red triangle is always on in the taskbar.

It seems to me that the fix should be simple: replace the Ubuntu package with the generic Unstable version of the Debian package.

I can confirm this on Kubuntu Edgy. The package from Debian unstable works.

This is the console output when Knights crashes:

Things are getting more interesting ....

I rebuilt the knights package from sources from a) the ubuntu and b) debian unstable sources (.orig.tar.gz + diff) using debuild. Both final packages crash on castle with the same output.

The result is now the following:
- orginal edgy pkg - crashes
- original debian unstable pkg - works
- edgy src rebuilt on kubuntu edgy - crashes
- debian unstable src rebuilt on kubuntu edgy - crashes

This looks like a problem somewhere else. Maybe some differences in dev packages ...? Or some "magic" in the sources, which fails to work correctly with the edgy dev packages.

Seems to me, then, that the answer is to put the Debian unstable package in the Kubuntu repository and simply rename it.

That may not satisfy the Kubuntu developers, but it would result in a Knights program that is current and doesn't crash.

This is indeed a bug in knights, see my comment from 2006-11-07 15:57 at

http://sourceforge.net/tracker/index.php?func=detail&aid=1587926&group_id=31461&atid=402242

The patch is attached to the sourceforge's bug report, to be sure I attached it here as well.

Could the package maintainer fix this please in ubuntu so that we don't have to wait for the next knights release?

Refreshing browser windows can be nice sometimes. Sorry about the spam.

[randcoop (rcooper)]

The package at ubuntu.lnix.net (see message above) works.

[Frode M. Døving (frode)]

If it's not fixed already, it won't happen for edgy i guess.
Was fixed for feisty.
