Note, however, that it is not running LOAD-FOREIGN-LIBRARY, as that would have it reloaded when the image is restored. For example, SBCL stores the loaded foreign libraries in its "shared objects" concept, and tries to restore them all by default when restoring. See also cffi#157 for a similar effect. By registering the c-file libraries as :static, using the recently-merged FOREIGN-LIBRARY-LOAD-STATE, we can make CFFI not use dlopen() after the image is restored, when the library will be needed.

This behavior is incorrect: the ASDF operation is generating a .so, which is a shared object not a static archive. You can't just declare it to be statically linked. |

Hm, indeed, it only works in the context of static-program-op. I'll try to think of a way to apply this state only for this operation. |
