Well, the conclusion would be that there is something wrong with the installation ;-) > I hesitate to claim that versions of (sexplib+bin_prot) libraries > published in GODI are faulty---if I do not use ocamlfind, I can use > those libraries just fine. It could be that there is more than one installation of these libraries on your system and that they are in conflict. E.g. if you ever installed type_conv outside of Godi. > Do not you think that camlp4 is never expected (for any kind of input) > throw an exception?

To make sure that things compile, please delete any potential other installations of the above libraries from your system. One problem that seems to have happened for some people is that they previously installed type-conv and bin-prot. These packages have been renamed to type_conv and bin_prot (complex reason). If they have been previously installed, you may now have both packages on your system. It seems Godi cannot determine renamed packages and will leave old ones in place. Please make sure to manually delete all files and directories in your Godi installation that match "*type-conv*" or "*bin-prot*". If in doubt, just completely reinstall Godi. I've just tested the current release, and it works for me. Regards, Markus -- Markus Mottl http://www.ocaml.info markus.mo...@gmail.com -- Caml-list mailing list.
