I am using an XL400 under Genera 8.0.
I am having a bunch of trouble getting packages defined correctly in a system I
have put together. A few files in the system require CLOS. Those files call
out ALP-CLOS in the top line. The package ALP-CLOS is defined as below:
(:shadowing-import documentation setf))
I wanted to define the package with the following CL code, by the Symbolics
doesn't support it:
(:shadowing-import-from "clos" documentation)
(:shadowing-import-from "clos" setf)
The system uses common lisp user as the default package; alp-clos is called out
as needed in particular files.
I first time i load the system, I get package problems; e.g.,
Trap: The function CLASS-PROTOTYPE is undefined
even though the defpackage code defined above has been loaded.
If I quit at this point and reload the system, I get:
Error: Making package ALP-CLOS use package CLOS causes name conflicts:
Package ALP-CLOS already contains ALP-CLOS::STANDARD-METHOD, ALP-CLOS::FIND-CLASS,
ALP-CLOS::CLASS-PROTOTYPE, ALO-CLOS::STANDARD-GENERIC-FUNCTION, ALP-CLOS::STANDARD.
When I choose the option:
<RESUME> Prefer the symbols from CLOS, un-interning or shadowing competitors.
everything loads and runs fine from then on.
How do I avoid this error loop? Is my defpackage wrong? Am I loading things in
the wrong order? I am quite perplexed. Any suggestions would be appreciated.
