Re: [Xbae-discuss] Xbae Matrix Core Dump on HP-UX 11

[Danny B. <dan...@sk...>]

Tony,

The r5 vs r6 difference by itself could cause all sorts of problems.
Whether this is one of them is hard to tell without more information.

With the above, I mean that mixing software versions at compile-
and/or run-time is a recipe for disaster. I am not sure from your
message whether this is the case.

If you would have e.g. the Xbae widgets compiled against Motif 1.2
which itself was compiled against X11R5, and you would use that
together with UIMX widgets compiled against X11R6, then I would
say you're in for a surprise.

If on the other hand you have sources to everything, and compile
such that you're sure that the UIMX widgets, Xbae, and Motif all rely
on the same X version; and UIMX and Xbae rely on the same Motif version,
then things should work.

I'd say your first thing to look into is this (make sure to look
both at runtime and compile time dependencies). If all that is good
(consistent, I mean), then maybe we need to look at the exact error
message, stack trace, whether to use a more recent version of Xbae,
etc.

Please ask again if any of this is unclear.
