Hello,

I got this error message. Can anyone help?

	source_sink `library('dialect/ciao/aggregates')' does not exist

Probably you need to install the ciao pack using

?- pack_install(ciao).

Once upon a time part of this was in the core sources. It was moved to a pack and extended a lot by Edison Mera. Part of the reason is that there is a lot of Ciao code in it that has a GPL license rather than the BSD-2 license of SWI-Prolog.
