Question

我想在ubuntu 12.04上下载emscripten。我下载了Cmake 3.3.0然后我下载了esmscripten_portable并运行了这些命令：

    # Fetch the latest registry of available tools.
./emsdk update

# Download and install the latest SDK tools.
./emsdk install latest

我收到了以下错误消息：

    -- Could NOT find OCaml (missing:  OCAMLFIND OCAML_VERSION OCAML_STDLIB_PATH) 
-- Could NOT find OCaml (missing:  OCAMLFIND OCAML_VERSION OCAML_STDLIB_PATH) 
-- OCaml bindings disabled.

我安装了所有这些库但是当我运行此命令时：./ emsdk activate latest.I收到此消息：Emscripten配置文件/home/slim/.emscripten已使用以下内容重写：

import os
SPIDERMONKEY_ENGINE = ''
NODE_JS = 'node'
LLVM_ROOT='/home/slim/Bureau/emsdk_portable/clang/tag-e1.34.3/build_tag-e1.34.3_32/bin'
EMSCRIPTEN_ROOT='/home/slim/Bureau/emsdk_portable/emscripten/tag-1.34.3'
EMSCRIPTEN_NATIVE_OPTIMIZER='/home/slim/Bureau/emsdk_portable/emscripten/tag-1.34.3_32bit_optimizer/optimizer'
V8_ENGINE = ''
TEMP_DIR = '/tmp'
COMPILER_ENGINE = NODE_JS
JS_ENGINES = [NODE_JS]

To conveniently access the selected set of tools from the command line, consider adding the following directories to PATH, or call 'source ./emsdk_env.sh' to do this for you.

   /home/slim/Bureau/emsdk_portable:/home/slim/Bureau/emsdk_portable/clang/tag-e1.34.3/build_tag-e1.34.3_32/bin:/home/slim/Bureau/emsdk_portable/emscripten/tag-1.34.3

我跑：

source ./emsdk_env.sh

但是当我运行命令时：

./emcc v

我得到了：

bash: ./emcc: No such file or directory

下载emscripten时出错
