[cl-graph-devel] find-connected-components gives error at subgraph-containing

[Gary King]

Hi Deepak,

I don't think this is a CLOS problem. Several years ago when I was trying to reorganize and simplify cl-graph, I pulled the subgraph-containing code out into a separate system that requires moptilities:

> #+asdf-system-connections
> (asdf:defsystem-connection cl-graph-and-moptilities
>   :requires (cl-graph moptilities)
>   :components ((:module 
> 		"dev"
> 		:components
> 		((:file "subgraph-containing")))))
> 

There are a bunch of reasons subgraph-containing isn't loaded:

* moptilities isn't around
* asdf-system-connections isn't around
* asdf-system-connections doesn't work with the latest ASDF (it may but I know I haven't tested it myself :-()

So the first thing I'd do is see if subgraph-containing.cl has been compiled and loaded. If not, then that's probably the source of the error message you're seeing. To fix it, you should get moptilities and then load them and maybe load subgraph-containing.cl by hand.

Let me know how it goes,

That's a great tag-line!
