The simplest approach is to put "libsqlite3.dylib" in Racket's "lib" directory. Read further only if that's not good enough. The parts of Racket that load foreign libraries generally go through `ffi-lib`. There's a search path description in the docs for `ffi-lib`, but it chains to several other things. Mostly, the search path is based on `get-lib-search-dirs` from `setup/dirs`. That search path can be configured though Racket's "etc/config.rktd", but that's probably not what you want to change. The first result from `get-lib-search-dirs` is a user-specific directory; that's probably not what you want, either, but it's based on `(find-system-path 'addon-dir)` and the Racket version number (or, more precisely, the installation name). Finally, the last step in the `ffi-lib` search is to let the OS perform it's own search. If I remember correctly, Mac OS will search based on the `DYLD_LIBRARY_PATH` environment variable. -- You received this message because you are subscribed to the Google Groups "Racket Users" group.
