Hi Stephan,
Wow, what a useful webpage! I wish it was linked to from
redwoods.stanford.edu!
Now, reports from the field.
I ran the install script, modified the export script to only export
:dependencies, and ran it like
./export redwoods/jun-04/vm6/04-06-11
(after fiddling with LD_LIBRARY_PATH to make libXm visible) on a recent
Fedora machine with 500m of RAM.
The result:
[changing package from "COMMON-LISP-USER" to "LKB"]
LKB(1): Error: An explicit gc call caused a need for 532938752 more bytes
of
heap. The operating system will not make the space available
because of a lack of swap space or some other operating system
imposed limit or memory mapping collision.
Well, I said, fine. I'll find you more memory. I installed on one of
stanford's vine machines (2GB ram, debian 3.0).
a) uname does not understand -i on this machine. I created a wrapper.
b) libc against which libXm is linked is different from libc on this
machine. bomb.
Well, I said, fine. I'll give you a Solaris machine. So I installed on
on one of Stanford's tree machines. After chaning export to run the
solaris tdsb, i got it to churn for a while, until it bailed with
[changing package from "COMMON-LISP-USER" to "LKB"]

But it did get up to
exporting `redwoods/jun-04/vm6/04-06-11' [4000 -- 4200]
before then, so may be the output is lying around somewhere? If so,
where?
Thanks
Anton
