[comp.lang.lisp] VaxLISP 2.2/Ultrix -- Calling external routines?

hall@aplcen.apl.jhu.edu (Marty Hall) (03/06/90)

Sorry to post an implementation-specific question, but the University
sysadmins were not able to provide me with a phone # or email address
for DEC LISP S/W suport.

According to the documentation, the following should let me use
shell commands from wi/ LISP:

(define-external-routine (system :entry-point "_system")
  "Optional documentation"
  (command :lisp-type string :vax-type :asciz) )

However, when I do

(call-out system "date")

I get an error message saying that call-out entry point _system could
not be located in /tmp/vaxlispfoo123.o. There is also a message saying
something about an illegal magic number in the file ~/lisp.

Any suggestions? A phone number or email address for vaxlisp S/W
support would be welcome also. This is probably not of general interest
to the net, so please email. Thanks.
