gEDA-user: reload library directories while in gschem
I have the following line in my system-gafrc,
(component-library-search ${HOME}/projects/sym)
which searches that directory for symbols and symbol directories when
starting gschem. If I add a directory when working in gschem (e.g. I
did not have any opamps, and then made a new opamp directory for
those) I have to exit gschem and restart to see the symbols from that
directory.
Is there any way to reload the directories while in gschem, or is
restarting the only option?
Thanks,
Duncan

gEDA-user: pcb build problem
Anyone know what the following means when running configure for pcb? : config.status:742: creating Makefile config.status:877: WARNING: Makefile.in seems to ignore the --datarootdir setting I'm using: ./configure --prefix=/home/des0prb/geda --enable-maintainer-mode under Fedora 7 on pcb checked out from cvs today. I get a similar message in config.log for the other Makefiles as well, and make install fails because it tries to install to /pcb (ie it really does ignore datarootdir). I've a feeling I'm doing something daft, but I can't see what.

gEDA-user: PCB: Lost custom element data when file is reopened ? Bug ?
I spent the morning making 4 new elements. PCB worked great. I saved my work every 5 minutes. I closed PCB. I regenerated the netlist from the schematic due to a change. I used gsch2pcb myfile.sch to regenerate the netlist. I opened myfile.pcb with PCB. My custom elements are missing. Where did they go ? This actually happened to me yesterday as well.

This actually happened to me yesterday as well. Thanks gschem2pcb removed them because it didn't believe they were part of the net-list. Were they named correctly in PCB? If it removes correctly named elements which should be part of the netlist, and in the schematic have the correct footprint= attribute, then its probably a bug. gsch2pcb behaves the way it does this because of the case where you may change a footprint in the schematic, and you'll then need to delete and re-place it in PCB, or if you delete a component completely from the schematic. You really need to save your custom footprints in a file which gsch2pcb can find by looking at the footprint= attribute. It should then not delete these components. Before you re-create the work, take a look for the backup files gsch2pcb makes when altering your schematic. You may be able to find the elements you just lost.

Why did this happen ? myfile.pcb.bak0 has the custom elements in it because gsch2pcb saves a backup before modifying your design ;) I've had it happen to me to, occasionally for no apparent reason - that gsch2pcb doesn't think the footprint on your PCB matches the one it should be. In your case, its probably because gsch2pcb didn't insert those elements. You should save each element to a .fp file and set the footprint=... attribute in your schematic to match the filename (no .fp needed). Put the .fp files in a subdir, packages from your working directory. Alternatively, pass -d PATH on the gsch2pcb command line, then gsch2pcb will be able to find and insert them for you. You may like to play with changes such as the following in your .pcb file to avoid having gsch2pcb delete your existing footprints and replace them: As a test, I just tried it on one of my designs. If you break a footprint to pieces, make it an element again, give it the right refdes, gsch2pcb will replace it. This is the difference after breaking it up and replacing: After breaking up / re-pasting: Element[ CONN4 6 12 0 0 0 100 ] What gsch2pcb inserts: Element(0x00 25m CONN4 unknown 1000 2566 1 150 0x00) NB: By changing the above line in the .pcb file after re-pasting, (ignoring the coordinates, thats not the point), gsch2pcb no-longer replaces my footprint. This is probably because its trying to match the footprint=25m in my schematic. Try setting the right footprint name in the argument list before the refdes, and see if that makes gsch2pcb happy.

Re: gEDA-user: PCB: Lost custom element data when file is reopened ? Bug ?
Make sure the description field of the element matches the footprint name, and that the refdes is the same. Those are the fields gsch2pcb uses to determine if an element doesn't match the schematic. You can change the description by View-Description then n to rename it. Save that .bak0 file somewhere safe while you figure this out ;-) ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
Re: gEDA-user: PCB: Lost custom element data when file is reopened ? Bug ?
I suspect that gsch2pcb overwrote your project file. Did you save the custom elements individually? Have you looked to see if you have a backup project file? myproject.pcb- for example.

In addition, Omniscient International is sponsoring the class in Singapore and Malaysia in October (see http://omniscient-intl.com/). I'm always peppered with email from companies looking for consultants. A lot of Muse subscribers are. Why not send me your profile so I can connect folks based on their services? Send your specialties and geographic region. The sheer number of blogs is overwhelming. It's hard to find any worth following. But Steve Leibson's at http://www.edn.com/index.asp?layout=blogblog_id=98298 is always interesting. He's also a big fan of the history of this industry, and serves as a docent at The Computer History Museum (http://www.computerhistory.org/ ) in Mountain View, CA. When he gave me a tour he told me that for most folks it's only an hour. But for us, figure on three. And what a tour it was. If you're out there it's a must-see. I enjoyed an article in the August 2007 issue of IEEE Computer. Les Hatton, noted software researcher wrote The Chimera of Software Quality. A particularly noteworthy excerpt: Computer Science regrettably operates in a largely measurement-free zone. Researchers do few experiments, and even fewer publish their results. . As a result, software development isn't an engineering industry, but a fashion industry populated by unquantifiable statements and driven by marketing needs. We are exhorted to develop using JavaBeans, OO, or UML because these technologies will supposedly fulfill our wildest dreams. Secure Software --- It's hardly novel to say software security is important. What hasn't gotten much mind-share is secure embedded software. We talk a lot about reliable designs but usually security takes a back seat. Yet so many of our creations are linked to the Internet, and are subject to all of those threats. In fact, last week Forbes magazine had an article (http://www.forbes.com/security/2007/08/22/scada-hackers-infrastructure-tech-security-cx_ag_0822hack.html ) about hacking the SCADA systems that control all sorts of industrial processes, including nuclear power plants. These are all traditional embedded systems, some of quite of ancient heritage. Some are connected to the Internet. A few companies, like Green Hills, are aggressively creating products positioned to deal with these threats, but they are in the minority. Clearly, secure embedded technology will become a huge issue in the next few years. Rod Chapman of Praxis and SPARK fame sent me a link to a new report called Software Security Assurance (http://iac.dtic.mil/iatac/download/security.pdf ). It's very long (396 pages) but is absolutely topical. Like all of these things it's wordy and full of acronym soup, but does make some interesting and important points. A lot is less useful, but everyone should read the section starting on page 170 about design principles for secure software. There's nothing startling there, but somehow these ideas continue to be neglected. The table on pages 139-140 offers a great summary of what makes good requirements. The report is really a compendium of pointers to other sources. I recommend at least a quick look at it.
