Subject:PC Windows Poplog can now be extracted with Winzip 
From:Aaron Sloman See text for reply address 
Volume-ID:990727.01 

After I announced this

> The Poplog multi-language AI development system is now available free of
> charge, with full system sources.
> ..
>     ftp://ftp.cs.bham.ac.uk/pub/dist/poplog/freepoplog.html

unfortunately, some people found that after fetching the PC Windows
9x version of Poplog they could not extract it with WinZip because
each subdirectory in the tar file had an empty file, and WinZip
decided that because they were empty they could not possibly be
needed, and therefore did not extract them.

This screwed up installation of Poplog, alas (I don't know why).

An extracter from PCWARE worked fine.

Some people managed to get it to work by creating the required empty
files, i.e. disk1.id in disk1, disk2.id in disk2, etc.

Anyhow I have now rebuilt the tar file after replacing the empty
files with dummy NON-empty files. It is in

    ftp://ftp.cs.bham.ac.uk/pub/dist/poplog/new/pcwin-15.5.tar.gz

Now even Winzip believes they are needed and extracts them, so that
installation works.

Apologies to anyone who wasted time fighting the original version.

If you know the makers of Winzip tell them not to do things like
that....

(Note the PC version of Poplog has none of the graphical facilities,
and some of the interfaces to the operating system don't yet work
properly. Maybe some PC expert will look into the problems and fix
them?)

MIRROR SITES
If anyone wishes to set up a mirror site for poplog, I'll try to
keep a set of links in this directory

    ftp://ftp.cs.bham.ac.uk/pub/dist/poplog/.for.mirrors/

to all the files that need to be fetched.

Comments and suggestions to comp.lang.pop please.

Thanks.
Aaron
