Compilation failed with "error: ‘caml__frame’ undeclared"

[jared-wallace]

I got this error when compiling on Fedora rawhide, which uses Ocaml 4.04.

I know nothing about Ocaml, but some googling yielded this patch, which fixes the issue.

I have a similar error trying to compile orpie in Arch, but this patch didn't work for me.
Orpie is currently broken for Arch users.

I confirm the same error on Manjaro linux

I applied both the patch mentioned in the issue OP, as well as the patch currently included in the AUR package. Both fixed errors during build. However, I now get a third error:

Error: No implementations provided for the following modules:
         Gsl_sf referenced from rpc_calc.cmx
         Gsl_math referenced from rpc_calc.cmx

Fixed in 1a2d225 (by removing the local copy of ocamlgsl).
