无法将 libsvm 与 OCaml 一起使用

Question

我尝试在 OCaml 项目中使用 libsvm :

open Lacaml.D
open Libsvm

但是，当我尝试运行我的 makefile 时遇到了这个奇怪的错误：

ocamlfind: Error from package `threads': Missing -thread or -vmthread switch

我的 makefile 是：

ocamlfind ocamlopt -o prog -linkpkg -package lacaml -package libsvm Example1.ml

我确保所有包都存在（使用 depext）：

# Installed packages for system:
base-bigarray             base  Bigarray library distributed with the OCaml compiler
base-bytes                base  Bytes library distributed with the OCaml compiler

您必须通过为其提供选项 -thread 或 -vmthread 来指示 ocamlfind select 线程库 - 请参阅 ocamlfind
