The M4 library will keep accumulating cruft otherwise. I thought we were talking about gschem symbols, gschem doesn't use M4 at all. PCB used to use M4 for (all?) its footprints, but now many are just shipped in their raw output format "newlib". The PCB build process now actually makes a newlib copy of all M4 footprints it knows about, installing as pcblib-newlib. (Necessary for a win32 port where launching M4 won't work - certainly not easily). There are a few drawbacks, not as much information is listed in the filenames of the converted footprints, and there are still a few name clashes which mean you don't get some footprints in the converted output. As you suggest though, the PCB library could probably benefit from some cleanup too. > I think we should embark on a yearlong project to assemble and verify a > basic symbol set.

I was wondering about some kind of web-based symbol / footprint review database, we can upload the existing sets, and mark them as needing review. If we had a way to categorise how good symbols are, and mark them as reviewed etc.. then we could all help. Someone would have to decide the desired library content for the shipped gEDA / PCB tools though. > > Since these meters are quite common items, I guess there is more chance > > we can include them (assuming they are appropriately licensed > > (http://geda.seul.org/license.html) > > That won't be a problem. Cool, lets see what Ales says about getting them included. -- Peter Clifton Electrical Engineering Division, Engineering Department, University of Cambridge, 9, JJ Thomson Avenue, Cambridge CB3 0FA Tel: +44 (0)7729 980173 - (No signal in the lab!) _______________________________________________ geda-user mailing list [email protected] http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
