I have now downloaded it from SVN, compiled and tested it. I have an Ubuntu 8.10 and for obvious reasons gerbv compiles on it. ;) I also downloaded emc2 from git repository and complied it as a simulator target. Before I realized I needed the bwidget package it took some frustration. Else emc2 seems targeted at Ubuntu and also has a liveCD based on Ubuntu with everything on. I used the examples from gerbv as samples. They are quite big and complicated. In very many cases, the program either segfaulted or tripped an assert in the program. One of the examples that actually worked was l1-1.grb and that is two polygons in G36-G37. So that actually works, though it seems to be other issues. After a while I also found DJ's laminater where he kindly left some Gerbers. I tried laminator.front.gbr and that worked too. It is kind of complicated layout, not as the simple sample/test layouts. That proves G36 from PCB works too. In the cases it worked it was quite cool to be able to run pcb2gcode, load the generated file into emc2 and see and 3D rendered drill sweeping across the board milling out the traces from the gerber. Anyhow, I think this pcb2gcode has potential, given some time and maybe some helpful hands. That is at least what I think.

Re: gEDA-user: SMT assembly and gerbv lilbro.mosquito.net.nz
John Griessen wrote: lilbro.mosquito.net.nz is starting a low volume assembly business and they are choosing software to deal with relating solder paste dots and pick and place centroids to gerber output that made the boards they are assembling. Could gerbv be modified to generate lists of pads after finding where silk outline intersects or encloses soldermask openings? gerbv has basically a notion of vectors and this seems like more of a graphical problem. I am in the favour of one program solves one problem. The solution would might be some plugin API in gerbv to expose the internal data structures, but it is currently in the idea stage. Anyone wanting to hack some gerbv is always welcome on the gerbv-devel mailing list. They won't have anything but gerbers from most customers. That means there is no netlist associated, no pin 1 defined, only a mark on one corner of the silk outline that you have to see somehow. When you have placement information available in your program it would seem like a great idea to support that. There is an european PCB vendor that supports one free CAD, you send your design in the format used by that CAD program and they makes your PCB from that. So to accept designs that (not to be mentioned) CAD program and/or PCB could give a slight competing edge and you don't have to cross the river to get some water. Just my 50 öre...

[EMAIL PROTECTED] wrote: Stefan Petersen wrote: 2) The aperture macro also contains operations like $4=$1X$5. My copy of Gerber Format: Plot Data Format Reference Book is quite old, (c)1993. But some of the examples use the $4= construct to work around the severe restriction on expressions: Only one operator is allowed between commas., and Only one operator is allowed on the right side of the equals sign. If one wants to do anything remotely fancy, one almost has to use this gimmick. I wonder if these restrictions have been eased lately? Even simple left-to-right without operator precedence would be a big step up. I think it is basically the latest version of the manual around. :) I have not done my homework properly and read the book as the devil reads the bible. As the rewrite progress (other people are doing the job rewrite of the graphical stuff and other patching up here and there) I will look into this. I seem to remember running into this problem back with V1.0.2, and thought I might take a whack at fixing it, but I recall gerbv is written mostly in Scheme. To me, it might as well have been written in Boustrophedon. I know that Scheme is a beautiful language, and I've taken a couple of stabs at learning it, but I still don't know my cdr from a hole in the ground! gerbv is written in plain C with GLib and GTK as extension. It uses Scheme currently for project files only. A long time you could write backends (to generate other files from the parsed gerber) in Scheme. But that broke a long time ago when I changed built-in Scheme interpreter. Ah you saw the scheme directory and that scared you off. Look in the src directory and you be much relived. :) Regards, /Stefan ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
Re: gEDA-user: gerbv - abnormal exit (2nd attempt)
Hello! Thanks for the report. Of course there should not be any dumping of variables or severe crashing so that is a bug for sure. gerbv is in the middle of a major rewrite, so hopefully we might get this into the rewrite. I set it up as bug at least. Or if you want to do it. Looking at the gerber you send along there are two things I notice: 1) There is some kind of comment in the middle of the aperture macro. That is according to the manuals _I_ have seen not legal. Maybe there is something I have completely missed out. 2) The aperture macro also contains operations like $4=$1X$5. When I wrote the aperture macro parser (5 years ago) I was not aware of that this was a legal operation. The last half year something there has come several reports of (I think) Mentor Graphics generating these kinds of aperture macros. Unfortunate I have felt that I have painted myself into a bit of a corner when I wrote the parser, so it is not an easy task to add. The parser compiles the aperture macro into a small assembler program, where the assembler part is a very small stack based thing with eight operations. Not any operation support the $4= part.

Of course, these data may be bogus, but I suspect the developers didn't intend memory corruption to result. Platform: Fedora 8 (including GCC, and requisite libraries). Indeed, I *think* the data are fine. Close examination should reveal the macro renders two rectangles overlapped to form a larger rectangle with four small squares removed from its corners. The squares are then filled by four circles centered so the result is a rectangle with its pointy bits rounded off. If I remove the - from between Round and cornered in the aperture macro comment, gerbv displays *something*, but I don't believe it is right. If I replace the - with an X, I'm back to the stack dump. It appears the comment is somehow mistaken for an expression. J.
