[clpython-devel] Re: CLPython on SBCL

[Leonardo Varuzza]

Same error with SBCL 1.0.16.11 on AMD64:

; compiling (DEFCLASS PY-DICT ...)
debugger invoked on a SIMPLE-ERROR in thread #<THREAD "initial thread"
{100244CF51}>:
  The stream
  #<SB-SYS:FD-STREAM for "file
/home/varuzza/lisp/prog/clpython/core/early-dict.fasl" {10039AD0F1}>
  has no suitable method for STREAM-ELEMENT-TYPE, and so has fallen through
to
  this method.  If you think that this is a bug, please report it to the
  applicable authority (bugs in SBCL itself should go to the mailing lists
  referenced from <http://www.sbcl.org/>).

Type HELP for debugger help, or (SB-EXT:QUIT) to exit from SBCL.

restarts (invokable by number or by possibly-abbreviated name):
  0: [RETRY ] Retry performing #<ASDF:COMPILE-OP NIL {10037950A1}> on
              #<ASDF:CL-SOURCE-FILE "early-dict" {10032E1401}>.
  1: [ACCEPT] Continue, treating #<ASDF:COMPILE-OP NIL {10037950A1}> on
              #<ASDF:CL-SOURCE-FILE "early-dict" {10032E1401}> as having
been
              successful.
  2: [ABORT ] Exit debugger, returning to top level.
