Hello. The OCaml manual states that executing bytecode program with "./prog" and "ocamlrun ./prog" should give the same result (in simple case, without options and environment modifications). However in my case the result is different: "./prog" executes well, but "ocamlrun ./prog" gives "Fatal error: unknown C primitive `unix_dup'".
But I have no good minimal case (other small unix.cma-dependent programs run fine both ways), and I can't show the full sources due to my contract with employer. I suspect this issue can give me additional headache in the future, so I prefer to solve it now. How can I find the source of this problem? What I have checked for now: - host OS is linux (gentoo, fresh enough) - the host contains (and contained ever) only one OCaml installation (3.11.2), and I can't install more recent OCaml versions system-wide (and I want this program to work under system-wide 3.11.2 anywhere) - ocaml toplevel doesn't fail on "#load "unix.cma"" and on calls to functions of Unix module - this system doesn't provide ocamlobjinfo, so I can't read its output - the program is built with ocamlbuild, without custom myocamlbuild.ml and other C-specific options, however some libraries may use C bindings (I'll check this if it is important) - I've tried to set environment variable LD_DEBUG=libs and run both cases: "ocamlrun ./prog" output is pasted to http://paste.in.ua/3499/raw/ , "./prog" output is pasted to http://paste.in.ua/3500/raw/ , but I don't understand where the problem is, even after meditation on these logs What should I do to diagnose this problem? -- Caml-list mailing list.
