[Sbcl-devel] Re: Problems loading foreign code under Mac OS X

[Brian M. <cha...@ac...>]

You have the wrong dlcompat library installed and linked to. Unfortunately
this is not an issue that we can really work around, as there are two
different versions of dlcompat. One of these prepends an underscore on
foreign symbols automatically, and the other does not. SBCL depends on the
latter behavior. I'm currently working on replacing dlcompat with a small
shim that replicates enough dl* functionality for SBCL and will allow us
to get past this confusion.

In the meantime I would suggest you reinstall dlcompat, passing it the
--enable-fink option in ./configure.

Hope that helps,
