While cygwin cannot load shared libraries from bytecode, it still can load pure bytecode dynamically. It is reasonable that there is a dynlink.cma for this case, and that camlp4lib.cma depends on it. findlib has a special mode for platforms that cannot load shared libraries dynamically. This mode seems to be broken - it calls a script safe_camlp4 instead of camlp4, and safe_camlp4 produces ad hoc a new camlp4-type executable that includes the required C libraries - without that trick you couldn't use json-static at all on these platforms: https://godirepo.camlcity.org/svn/lib-findlib/trunk/tools/safe_camlp4 The question is now whether the error is in this script (does it have to add dynlink.cma anyway?) or whether mkcamlp4 is broken. Can you try to change safe_camlp4 so the line mkcamlp4 -o $tmp_camlp4 $cp4_mods || exit reads mkcamlp4 -o $tmp_camlp4 dynlink.cma $cp4_mods || exit ? (I don't have a cygwin ocaml at hand.) safe_camlp4 should be in the bin/ directory.
