What part doesn't go well? Is it the IUP egg, or the IUP library itself?
I've rarely had trouble with the former, often with the latter ...

I've been meaning for a while to update my IUP library. I've had some
struggles with that in the past, and have worked out some solutions ...
however, I'm on Arch Linux, so the issues may or may not be similar. At any
rate, once I've done that I'll post a report in case it is useful.

I'm not sure how to narrow this problem down but I'd like to start with a
fresh build of chicken / IUP. However that process never seems to go well
for me. Has anyone recently installed the chicken IUP egg on 64bit Ubuntu
15.04 or a recent Debian and if so would you be so kind as to share your
recipe for success? I'd like to avoid losing several evenings trying every
permutation and combination of install strategies.

Thanks.

Hello,

are the systems in question running on the same architecture? Do they
have the same word size?

My gut feeling says that the problem looks suspiciously like some
calling convention or data type conversion issue.

Ciao,
Thomas

[Chicken-users] strange IUP canvas behavior - mouse clicks returning bad value

[Matt Welland]

obj: #, pressed 0, status   1
canvas-origin: 0 0 click at -1987635704 48

The -1987635704 is the x value returned by this callback:

#:button-cb (lambda (obj btn pressed x y status)
...

this is failing on Ubuntu 15.04 but working ok on sles11.

so far as I can tell this is not due to any changes in the code - running
an older version exhibits the save behaviour.

Any suggestions on what to look at?

Thanks,

Matt

Hi Matt--

My brain is not sure, but my finger is spontaneously pointing at the window
manager ;-)
