compilation error

[welvinyu]

I was not able to build the example using make. It first reports the following error: Makefile:145: .depend: No such file or directory make: *** No rule to make target `.depend'. Stop.

After the line 145 on the Makefile, I encounter the following error: ocamlfind ocamlc -I +compiler-libs -g -annot -bin-annot -w A-4-9 -warn-error A-4-9-10-27-32-33-34-39-45 -I +compiler-libs -package cryptokit -I +unix -c ttmap.ml findlib: [WARNING] Interface topdirs.cmi occurs in several directories: /usr/local/lib/ocaml/compiler-libs, /usr/local/lib/ocaml File "ttmap.ml", line 1193, characters 6-25: Error: Unbound type constructor modtype_declaration Hint: Did you mean module_declaration or type_declaration? make: *** [ttmap.cmo] Error 2

I wonder if it has to do with the version of OCaml I installed?

$ ocaml -version The OCaml toplevel, version 4.02.3

I have the same problem

$ make
Makefile:145: .depend: No such file or directory
make: *** No rule to make target `.depend'.  Stop.
$ ocaml -version
The OCaml toplevel, version 4.01.0

I did $ touch .depend as a workaround and then it got past that first problem. I'm using 4.02.1 right now and also have the same problem as welvinyu so I'm looking into that next.

I switched to 4.01.0 by using $ opam switch 4.01.0. I also had to remember to download the source tarball https://ocaml.org/releases/4.01.0.html which needs to be in the ../ocaml-4.01.0/ location. And the requirements are opam install sha batteries cryptokit benchmark ocamlfind, and then the examples still worked

Thank you Andrew. After switching to 4.01.0, it works for me now. A minor caveat, the shared library cryptokit is installed to a path different from what's specified by the ld.conf file. Appending that path it solves the compilation problem. I think you can close this issue now.
