[Openmcl-devel] Creating FFI interface in Darwin x86-32

[Gary Byers]

The way that this has always worked is that:

1) the populate.sh script tells the translator (ffigen, invoked via 
h-to-ffi.sh) to parse one or more .h files into corresponding .ffi 
files.

2) A lisp function (named PARSE-STANDARD-FFI-FILES - defined in
"ccl:library;parse-ffi.lisp") reads the .ffi file(s) produced in
the first step and creates .cdb files.

It's sometimes necessary to run the second step twice (to resolve
things that were forward-referenced.)

If you have the translator installed and the populate.sh script set
up, you can run all of the steps enough times by doing something like:

? (ccl:create-interfaces :midishare)
