[Xcircuit-dev] segfault in xcircuit 3.6.82

Tue Mar 13 03:42:54 PDT 2007

Dear Tim,

When I run xcircuit  from outside the installation folder it
segfaults, but when I start it from inside the installation folder it
runs just fine. I've included stackdumps from both. (In both occasions
I started the 'xcircexec' executable).
(running debian testing)

I've been using XCircuit for about 2 weeks now, having run through the
3 tutorials (which have been very usefull) , and tried out the 3.4 and
3.6 branches. These are my findings: (I'll keep it short)
Pro's
- I really like the overall feel of the program, the technology
prefixes in the 3.6 branch really eases the library management.
- Hierarchy works better than in any program I've used so far
- Postscript really works out well; I can use the same file for
editing, printing, and documentation.
- With XCircuit I can really soup up my schematics, as it's also very
usable for creating neat 2d drawings.

Cons
- Maybe I missed someting, but when I want to create a PCB (using
PCB), I have to place the footprints myself, and have to edit their
reference designators, in order to make use of the generated netlist.
- (This is only minor and doesn't bother me) While trying to convince
my classmates to give XCircuit a try, they all disliked its graphical
interface (though this was using the old xw system, the tk version in
3.6.82 already looks a bit better).

Best Regards,
Dimitri Princen
