Question

我正在尝试make install ocaml-wasm 1。

不幸的是，构建失败并显示错误消息：

Error: /usr/lib/ocaml/bigarray.cma is not a bytecode object file

这是一个Dockerfile，因此您可以重现该错误：

FROM base/archlinux

RUN pacman -Sy --noconfirm ocaml ocamlbuild wget unzip make
RUN wget https://github.com/WebAssembly/spec/archive/v1.0.zip
RUN unzip v1.0.zip

CMD cd spec-1.0; make -C interpreter install; bash

您可以运行它：

docker build -t ocaml-wasm . && docker run --rm -it ocaml-wasm

它应该发现它会产生与上述相同的错误。这是make命令的全部输出：

如何获取ocaml-wasm进行编译？

我见过2，但答案无济于事。我尚未安装任何非标准二进制文件。能否在arch linux上的ocaml发行版被破坏？

Answer 1

我怀疑您的ocamlbuild版本为0.13（请参阅ocamlbuild --version），已知存在此问题。您应该使用0.12来避免此问题。

由于这个问题，ocamlbuild 0.13不能在opam上打包（因此它对大多数用户不可见），但是我还没有考虑分发打包者可能会决定打包它。

ocamlc-编译ocaml-wasm-错误：/usr/lib/ocaml/bigarray.cma不是字节码目标文件

这是一个Dockerfile，因此您可以重现该错误：
