Hi,

I'm trying to run c program using old Xview :
http://inls.ucsd.edu/%7Efisher/Complex/spider.tar.Z

I have compiled test program from :
http://www.linuxjournal.com/files/li.../linuxjournal/
articles/020/2035/2035l1.html

using
gcc sample.c -o sample -I/usr/include/xview -lxview -lolgx -lX11

After run it I have error:
Segmentation fault

Is it possible to run that program ?

Regards

Adam

PS I have 64 bit Linux

Xview is from the eighties and from what I read it is not the most
portable code. One site suggests that there will never be a native
xview library for 64-bit systems[1]. For 64-bit systems, the code has
to run in 32-bit mode and it's possible the library you have obtained is
not suitable for your system.

There's not nearly enough information here to answer your question, but
I can make a couple of suggestions:

Compile the program with the -g option. If you have the sources to
xview, compile them with -g as well. Statically link your application
if you can.

Run the program with the gdb debugger:

$ gdb spider
(gdb) run

When the program segfaults, gdb will give you a pretty good idea of
where it happened and why.

With luck, the problem will be obvious and easy to fix. Without luck,
you'll find yourself in a tar pit.

There are probably other newsgroups better suited to help you with this;
perhaps even one dedicated to X11 and/or xview.

I fell compelled to ask, though: why are you doing this? Xview is a
very very old library. It was written as a portability layer to help
pre-X11 Sunview programs get ported to X11.

Program is intresting. It's algorithm is unique.
It's description is here

Thx for answer.
I will work on it.
