Subject: [lift-devel] Lift as of April 2010 not ASDF-INSTALLable on SBCL
	1.0.38
Message-ID: <68EA462D-AEB2-4720-9F88-233D7BE97CE8@nimbulous.com>

Apologies in advance if I've missed something, but it would appear that Lift in its present form released in April 2010 (and as installed by ASDF-INSTALL on 5/19/2010 & 5/20/2010) does not compile on SBCL.

I'm attaching a simple but crude script you can run with SBCL to reproduce the error.

Here's a snippet of the first error message encountered:

; compiling (DEFUN SUBCLASSES ...)
; compiling (DEFUN SUPERCLASSES ...);
; compilation aborted because of fatal error:
;   SB-INT:SIMPLE-READER-PACKAGE-ERROR at 7651 (line 199, column 39) on #<SB-SYS:FD-STREAM
;                                                                         for "file /Users/phil/src/lift/ext/site/lift/dev/utilities.lisp"
;                                                                         {1003A35EB1}>:

As you probably know, the package for the Meta-Object Protocol on SBCL is SB-MOP, not MOP.  Note that I did try just removing the package qualifier MOP (since the package definition tries to use the package appropriate to each implementation), but further errors resulted.

Just speculating, but it would appear that these symbols were previously included in commented-out code as of a checkin of dev/macros.lisp on 2/27/2010, then later moved to (non-commented out) code in dev/utilities.lisp on 3/12/2010.

For now, this is not at all critical, as I have a version of Lift downloaded last fall that appears to load just fine. 

Let me know if I can help further with resolution of this problem.  Thanks much for such useful software!

:)

Subject: [lift-devel] Having problems compiling with SBCL
Message-ID: <85CD6AD6-E24C-4AA5-8E81-1EDB233DAA50@clemson.edu>

The original problem is in 'lift/utilities.lisp' line 199: 'mop:slot- 
definition-class

There's no such symbol. There is a #+sbcl sb-mop which I'm assuming  
should solve the problem. sb-mop is a package. Do I not have a  
prerequisite or something simple?
