RE: gEDA-user: Newby Question on Symbols

[John Davies <john.davies@metagence.com>]

Thank you Stefan, it works.  So I put the filename.sym and the filenamesch
in ....geda/share/gEDA/sym/local and I was then able to see filename.sym in
the component-library under Local, include it in a schematic and descend to
the underlying circuit.  Unfortunately I have not been able to access
ftp://www.icarus.com/pub/eda/gtag/, or find the correct file type from the
top level. I think that the file is no longer on the site. But I am nearly
there.  The next stage is for me to put a gschemrc in my working directory
and include the appropriate working files within it.  I have tried this but
do not know the correct format to use.  I am assuming that I do not need to
include every schematic/symbol in ....geda/share/gEDA/sym/local, since this
would mix various projects.  Any suggestions as to how this is handled?

There are a couple of attributes that must be attached to the symbol so it
knows where to find the schematic, ie the filename of the schematic.

A good start. You must have the attribute source=filename.sch attached.

A couple of months ago I made a hierachial schematic. You can use it as an
example. Stephen Williams has gracefully put it on his ftp site:
ftp://www.icarus.com/pub/eda/gtag/

Good luck,
