That will get you a somewhat old version of Poplog, with a limited
heap size and motif statically compiled in. If you get it to work,
you can at least investigate pop-11 (and it also includes prolog,
common lisp, and standard ML), though the heap size limit will
get in the way of serious work.

That message reccomends the following:

| : high enough. Don't ask me why, but setting _STK_LIM in

I have not tried that as I don't use Linux myself (I use suns
running Solaris). I am merely passing on the information.

There is a new version of linux poplog (Version 15.53) which works
with Redhat 5.2 without motif, which we have been allowed to
beta-test, though we can't distributed it.

The instructions I have produced for our students can be read at

    ftp://ftp.cs.bham.ac.uk/pub/dist/poplog/help/linux.install

I don't know if they will be useful for people outside Birmingham.

My instructions say how to fetch the Birmingham local extensions to
Poplog/pop-11.

In particular my RCLIB package provides a lot of GUI facilities
based only on the Poplog widget set, so you need need to have motif.
It is in
    ftp://ftp.cs.bham.ac.uk/pub/dist/poplog/rctar.gz

I shall shortly be adding scrolling text facilities. I don't know if
it still runs on Poplog V15.0.

I don't know what the procedures are going to be for distribution.
Sussex and ISL are discussing arrangements for this I believe.

My personal view is that although pop-11 is (at present) the core of
the Clementine data-mining system, which is sold and used
world-wide, the only way to get pop-11 out of its current trough of
usage in academe is to make it available completely free, at least
for academic users and personal use.

There's so much good free software, and academic budgets are so
stretched, that people no longer want to spend departmental funds on
compilers especially for a not very widely known system.

I think this point has been recognized.
