ocamlopt链接错误代码2 [英] ocamlopt linking error code 2

问题描述

我运行了命令opam install ocamlbuild，看来我在ocamlopt上遇到了某种问题

I ran the command opam install ocamlbuild and it seems that I have some kind of problem with ocamlopt

这是opam告诉我的:(我猜它只是不喜欢我的4.04版本)

Here is what opam is telling me : (I'm guessing it just doesn't like my 4.04 version)

谢谢.

推荐答案

从输出来看，您可以尝试重新安装当前为4.04.0的当前开关.

You could try reinstalling the current switch, which looks to be 4.04.0, judging from the output.

运行opam switch reinstall 4.04.0应该重新编译ocamlopt.opt二进制文件.

Running opam switch reinstall 4.04.0 should recompile the ocamlopt.opt binary.
