Re: [Plplot-devel] xwin driver bug under PseudoColor Xserver

[Alan W. I. <ir...@be...>]

I suspect this is one more variation on a chronic X_CreateWindow problem
that Maurice reviewed "fixes" of (stretching back 7 (!) years) in
http://sourceforge.net/mailarchive/message.php?msg_id=3D151054.

I suggest you temporarily change

case $system in
    SunOS-* )
            AC_DEFINE(USE_DEFAULT_VISUAL)
=09    ;;
    * )
esac

appropriately in configure.in to see see whether defining USE_DEFAULT_VISUA=
L
will workaround your problem for 8-bit pseudocolour X servers.  If it does,
that is one more clue about what the real fix should be.
