Subject: ocamlbuild and c libraries
Date: Wed, 27 Jun 2007 12:14:07 -0400 [thread overview]
Message-ID: <46828CCF.20901@janestcapital.com> (raw)
For the most part I tried to follow Nicolas's example on the previous
thread with similar name, but unfortunately I get an error that I do not
entirely understand.
My target is intern/live_query/live_query.native. It uses an ocaml/c
library called jane that lives in janebase/lb (thanks Nicolas, for the
renaming tip). In there exists a jane.mlpack, and a libjane.clib. Also
there is a couple of _tags file:
$ cat janebase/lb/_tags
<*.cmx>: for-pack(Jane)
<*.cmo>: for-pack(Jane)
<jane.cmx>: -for-pack(Jane)
<jane.cmo>: -for-pack(Jane)
<cephes>: include
<jane.cm{x,}a>: use_libjane
$ cat intern/live_query/_tags
<{single,live}_query.{byte,native}>: use_jane (i also tried
include_jane, this results in a different error message; in fact the
same error if I omit this _tags altogether, it says undefined references
in jane.o)
Also, myocamlbuild.ml :
$ cat myocamlbuild.ml
open Ocamlbuild_plugin;;
open Command;;
let packages = "bigarray,pcre,res,netstring"
let headers = ["janebase/lb/cephes/mconf.h";
"janebase/lb/cephes/protos.h"];;
let ocamlfind cmd =
S [A "ocamlfind"; A cmd; A "-package"; A packages;
A "-I"; A "+camlp4"; A "-pp"; A "camlp4orf";
A "-pp"; A "camlp4o /home/awarshaver/multi-oc/lib/pa_type_conv.cmo
/home/awarshaver/multi-oc/lib/pa_sexp_conv.cmo"];;
flag ["ocaml"; "compile"] (A"-thread");;
flag ["ocaml"; "link"; "program"] (S[A"-linkpkg"; A"-thread"]);;
dispatch begin function
| After_options ->
Options.ocamlc := ocamlfind "c";
Options.ocamlopt := ocamlfind "opt";
Options.ocamldep := ocamlfind "dep";
| After_rules ->
ocaml_lib "jane";
flag ["link"; "library"; "ocaml"; "byte"; "use_libjane"]
(S[A"-dllib"; A"-ljane"; A"-cclib"; A"-ljane"]);
flag ["link"; "library"; "ocaml"; "native"; "use_libjane"]
(S[A"-cclib"; A"-ljane"]);
dep ["link"; "ocaml"; "use_libjane"] ["janebase/lb/libjane.a"];
dep ["compile"; "c"] headers;
| _ -> ()
end
I can build the library ok...
$ ocamlbuild janebase/lb/jane.cmxa
+ ocamlfind c -package bigarray,pcre,res,netstring -I +camlp4 -pp
camlp4orf -pp 'camlp4o /home/awarshaver/multi-oc/lib/pa_type_conv.cmo
/home/awarshaver/multi-oc/lib/pa_sexp_conv.cmo' -c janebase/lb/cephes/main.c
janebase/lb/cephes/main.c: In function ‘main’:
janebase/lb/cephes/main.c:9: warning: control reaches end of non-void
function
Finished, 286 targets (0 cached) in 00:01:12.
But not my target..
$ ocamlbuild intern/live_query/live_query.native
Solver failed:
Ocamlbuild knows of no rules that apply to a target named jane.cmx.
This can happen if you ask Ocamlbuild to build a target with the wrong
extension (e.g. .opt instead of .native) or if the source files live in
directories that have not been specified as include directories.
Backtrace:
- Failed to build the target intern/live_query/live_query.native
- Building intern/live_query/live_query.native:
- Building jane.a:
- Failed to build all of these:

Compilation unsuccessful after building 358 targets (358 cached) in

Insights appreciated!
Thanks,
Andrew
