Try what's documented in /usr/share/doc/Cygwin/_autorebase.README for DLLs under non-standard system paths: create a file /var/lib/rebase/dynpath.d/ocaml containing your .so directory path /usr/lib/ocaml/stublibs/: $ echo /usr/lib/ocaml/stublibs/ > /var/lib/rebase/dynpath.d/ocaml then rebase-trigger full, shutdown all Cygwin processes, rerun setup, and your Cygwin setup should be properly rebased including your added DLLs/SOs. If you were testing as a user, you should add your build paths to /var/lib/rebase/user.d/$USER e.g. $ echo $HOME/src/build/lib/ocam/stublibs/ > /var/lib/rebase/user.d/$USER and do the above to pick up the added paths and include them in the Cygwin rebase database. -- Take care.
