compiler-errors - 无法将libsvm与OCaml一起使用

Question

我试图在OCaml项目中使用libsvm:

open Lacaml.D
open Libsvm

但是，当我尝试运行我的makefile时，我遇到了一个奇怪的错误:

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

我确保所有软件包都存在(使用depext):

您必须通过给它选项-thread或-vmthread来指示ocamlfind选择线程库-请参见ocamlfind
