Hi All, I am trying to build the latest version of Ocaml and FlexDLL on windows using msvc toolchain. There appears to be a circular dependencies on these two packages. OCaml build required Flexdll as specified in the README.win32 file set FLEXDLLDIR=%PFPATH%\flexdll And the FlexDLL build requires ocamlopt from the ocaml package to build flexlink.exe ocamlopt -g -w -105 -o flexlink.exe -cclib "-link version.res" version.ml coff.ml cmdline.ml create_dll.ml reloc.ml How do we compile ocaml if we don't have binary of flexlink? Also are they really completely backwards compatible so that we can use "any" older version of flexlink to compile the latest ocaml package to produce ocamlopt and then use ocamlopt to build the latest version of flexlink? Do we than recompile ocaml package to use the newly build flexlink? We have an old version of ocaml packages which is independent of flexlink 3.10. Can we use this version to compile the latest version of flexlink and then use this to compile a newer version of ocaml?
