[cl-objc-devel] Build Issues on OS 10.5.1 PPC

[Jeremy Shoemaker]

Hi,

Continuing from a previous discussion I was having directly with Luigi
Panzeri about this issue.  I was having problems with unknown foreign type
errors.

I'm running Leopard (10.5.1) on a PowerBook G4 under SBCL v.1.0.2

I've quoted his initial response.  He suggested I ask here to see if someone
else has the solution, though my initial problem was solved by his
suggestion.  I've run into a new problem though.

This was the source of the type error messages, but when I fixed that and
tried again, I got these errors from SBCL:

==== START OF LOG ====
Compiling CLOS bindings for Appkit framework in
/usr/local/lib/sbcl/site/cl-objc/src/frameworks/Appkit-CLOS.lisp
Control stack guard page temporarily disabled: proceed with caution

debugger invoked on a SB-KERNEL::CONTROL-STACK-EXHAUSTED:
  Control stack exhausted (no more space for function call frames).  This is
probably due to heavily nested or infinitely recursive function calls, or a
tail call that SBCL cannot or has not optimized away.

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:LOAD-OP NIL {11ABD101}> on
              #<ASDF:CL-SOURCE-FILE "generate-frameworks-bindings"
{11AC19A9}>.
  1: [ACCEPT] Continue, treating #<ASDF:LOAD-OP NIL {11ABD101}> on
              #<ASDF:CL-SOURCE-FILE "generate-frameworks-bindings"
{11AC19A9}>
              as having been successful.
  2: [RETRY ] Retry installation
  3: [ABORT ] Exit debugger, returning to top level.
==== END OF LOG ====

Retrying does nothing to help with this problem, and even eventually leads
to bad memory accesses on the part of SBCL, and an eventual seg fault.

Oh yeah, I'm using ASDF-Install to install Cl-ObjC by running the following
in SBCL:

(require 'asdf)
(require 'asdf-install)
(asdf-install:install 'cl-objc)

Anyone have any idea what might be the problem?

Thanks,
Jeremy Shoemaker
