[Gcl-devel] RE: [Axiom-developer] building Axiom with GCL Version_2_6_7pre fails

[Mike Thomas]

Hi Bill.

| Can you imagine what recent change (last week?) might lead

| routine?

You are right; the probe-file change.

(probe-file "./") returns nil on Windows with the latest changes.

In daase.lisp.pamphlet the "./" is hard wired:

  (localdatabase nil
     (list (list '|dir| (namestring (probe-file "./")) ))
     'make-database)



Lispworks gives:

CL-USER 1 > (probe-file "./")
#P"C:/Documents and Settings/miketh/"

CL-USER 2 > (truename "./")
#P"C:/Documents and Settings/miketh/"



Corman Lisp gives:

(probe-file "./")
NIL
(truename "./")
#P"C:/Documents and Settings/miketh/"

CLISP:

[1]> (truename "./")
#P"C:\\Documents and Settings\\miketh\\Desktop\\"
[2]> (probe-file "./")

*** - no file name given: #P"C:\\Documents and Settings\\miketh\\Desktop\\"
1. Break [3]> :C 1


Windows GCL currently follows Corman on this one and the Hyperspec says
this:

Common Lisp experts:

1. Which behaviour is correct on Windows?  (I believe that "." and ".." are
actual entities on Unix, but not Windows.  Convenience argues for following
LW rather than Corman.)

2. What is the system independent way to get the name of the current
directory in Common Lisp?


Cheers
