Re: matlisp on Mac OS X (Intel)

Jan,

Okay.  I think I've found the problem.   Go back to the file  
configure.in and edit the block that deals with Darwin.  Change  
things so that you end up with:

FLIBS="-llapack -lblas -lg2c -lSystem /usr/lib/dylib1.o"
SHARED_LIB_LDFLAGS="-dylib -single_module"

Then run:

	autoconf configure.in > configure

and then run

	./configure --prefix=`pwd` --with-fflags="-O3 -fPIC"  --with- 
lisp=sbcl --with-lisp-exec=sbcl

This will create a libmatlisp.so that CAN be loaded into sbcl and  
which will allow the 'make' process to run to completion (i.e. the  
loading and processing of 'start.lisp' works).
Note that the -llapack -lblas entries in the FLIBS statement will  
load the apple vecLib framework optimized lapack and blas libraries  
as can be seen in the resulting shared object:

% otool -L lib/libmatlisp.so

lib/libmatlisp.so:
         ./lib/libmatlisp.so (compatibility version 0.0.0, current  
version 0.0.0)
         /System/Library/Frameworks/Accelerate.framework/Versions/A/ 
Frameworks/vecLib.framework/Versions/A/libLAPACK.dylib (compatibility  
version 1.0.0, current version 192.15.0)
         /System/Library/Frameworks/Accelerate.framework/Versions/A/ 
Frameworks/vecLib.framework/Versions/A/libBLAS.dylib (compatibility  
version 1.0.0, current version 192.15.0)
         /usr/local/lib/libg2c.0.dylib (compatibility version 1.0.0,  
current version 1.0.0)
         /usr/lib/libSystem.B.dylib (compatibility version 1.0.0,  
current version 88.3.7)

Anyway this seems to work for me.
Cheers,
