Hierarchical bus support: Support for hierarchical buses doesn’t exist yet.

Thank you very much, Roland.
I think your patch solved my problem.
“hierarchical buses” I mean to connect ports from different sub schematics using bus connections.
 We will try implement it . If we have any interesting development we will let you know as sincerely.

Thanks Roland Lutz, that solved my question.

Hi Roland,

We can compile this xorn package successful to use. But when we try to test it, we have this problem

xorn netlist /home/geda_lib/netlist_xorn_hier/mod_7seg.sch

`xorn-netlist' failed to load.
This is an error. Please report it to <email address hidden>

You should not install the experimental netlister to the same path as gEDA/gaf.

Instead, do either of the following:

a) install the experimental netlister to a separate path (specifying --prefix=/some/path at configure time), or

b) run the experimental netlister directly from the build directory (you will find the binary under src/command/ after running "make").

Thank you very much. I followed solution b and now I can run xorn command of experimental netlister ok. I will test it more.
