RE: gEDA: Loadable Icarus Targets

Thanks, -t:dll did the trick.  Any documentation on format of the conf files?

Where is stub.conf?  I don't see it in the latest snapshot or release 0.7.

Also, is there a way to reference *.tgt and *.conf files outside of the ivl/lib directory?

-Tom

See the null.conf as an example. You want this instead:

~  -t:dll
~  flag:DLL=test_target.tgt

Notice that the "-t:dll" should be exactly like that. It's a little
confusing, but the way it is. Also, you should lookin the stub
target as an example as well. In particular, you should base your
conf file on the stub.conf, which has some more stuff in it that
you generally want.
