我刚刚安装了一个名为Apron
的库,安装似乎已经完成了:
@ubuntu$ find -name "*apron*"
./lib/libapron_debug.so
./lib/libapron.a
./lib/libapron.so
./lib/libapron_debug.a
./local/lib/ocaml/3.11.2/stublibs/dllapron_caml.so.owner
./local/lib/ocaml/3.11.2/stublibs/dllapron_caml.so
./local/lib/ocaml/3.11.2/apron
./local/lib/ocaml/3.11.2/apron/libapron_caml_debug.a
./local/lib/ocaml/3.11.2/apron/apron.cmxa
./local/lib/ocaml/3.11.2/apron/libapron_caml.a
./local/lib/ocaml/3.11.2/apron/apron.cmi
./local/lib/ocaml/3.11.2/apron/apron.cmx
./local/lib/ocaml/3.11.2/apron/apron.a
./local/lib/ocaml/3.11.2/apron/apron.cma
我尝试了第一个例子:
(* with default setting:
apronppltop -I $MLGMPIDL_INSTALL/lib -I $APRON_INSTALL/lib
#load "gmp.cma";;
#load "apron.cma";;
#load "box.cma";;
#load "oct.cma";;
#load "polka.cma";;
#load "ppl.cma";;
#load "polkaGrid.cma";;
#install_printer Apron.Linexpr1.print;;
#install_printer Apron.Texpr1.print;;
#install_printer Apron.Lincons1.print;;
#install_printer Apron.Generator1.print;;
#install_printer Apron.Abstract1.print;;
let environment_print fmt x = Apron.Environment.print fmt x;;
let lincons1_array_print fmt x = Apron.Lincons1.array_print fmt x;;
let generator1_array_print fmt x = Apron.Generator1.array_print fmt x;;
#install_printer Apron.Var.print;;
#install_printer environment_print;;
#install_printer lincons1_array_print;;
#install_printer generator1_array_print;; *)
open Apron;;
...
然而ocaml -c file.ml
给了我Error: Unbound module Apron
open Apron;;
有谁知道为什么我无法加载Apron模块?非常感谢你!

我应该用'-I'选项指示Apron库的路径。由于它安装在OCaml的标准库中,您只需要编译:
ocamlc -I + apron -c file.ml
