使用emscripten生成python.cc.js

Question

我正在閱讀emscripten的教程 - https://github.com/kripken/emscripten/wiki/Tutorial以及在本地計算機上查看源代碼中的一些演示項目。

到目前爲止，我已經下載了源代碼並正確設置了我的.emscripten設置文件。

我在尋找一個參考找出：爲了創建/輸出「python.cc.js」和「python.html」，需要什麼系列的emcc命令？感謝以前嘗試使用emscripten的開發人員的任何提示。

這是我的.emscripten文件：

EMSCRIPTEN_ROOT = os.path.expanduser('~/Dev/emscripten') # this helps projects using emscripten find it 

# LLVM_ROOT = os.path.expanduser('~/Dev/llvm-3.0/cbuild/bin') 
LLVM_ROOT = os.path.expanduser('/opt/local/bin') 

# See below for notes on which JS engine(s) you need 
NODE_JS = 'node' 
SPIDERMONKEY_ENGINE = [os.path.expanduser('~/Dev/mozilla-central/js/src/js'), '-m', '-n'] 
V8_ENGINE = os.path.expanduser('~/Dev/v8/d8') 

CLOSURE_COMPILER = os.path.expanduser('~/work/closure-compiler/compiler.jar') # optional (needed for the benchmarks) 

TEMP_DIR = '/tmp' 


######################################################################################################## 


# Pick the JS engine to use for running the compiler. This engine must exist, or 
# nothing can be compiled. 
# 
# Recommendation: If you already have node installed, use that. Otherwise, build v8 or 
#     spidermonkey from source. Any of these three is fine, as long as it's 
#     a recent version (especially for v8 and spidermonkey). 

COMPILER_ENGINE = NODE_JS 
#COMPILER_ENGINE = V8_ENGINE 
#COMPILER_ENGINE = SPIDERMONKEY_ENGINE 


# All JS engines to use when running the automatic tests. Not all the engines in this list 
# must exist (if they don't, they will be skipped in the test runner). 
# 
# Recommendation: If you already have node installed, use that. If you can, also build 
#     spidermonkey from source as well to get more test coverage (node can't 
#     run all the tests due to node issue 1669). v8 is currently not recommended 
#     here because of v8 issue 1822. 

JS_ENGINES = [NODE_JS, SPIDERMONKEY_ENGINE] 

而這裏的，我運行了emconfigure ./configure命令：

calvins-MacBook ttys000 Sun Feb 05 11:47:32 |~/community/Python-2.7.2| 
calvin$ emconfigure ./configure

checking for --with-universal-archs... 32-bit

checking whether the C compiler works... no 
configure: error: in `/Users/calvin/community/Python-2.7.2': 
configure: error: C compiler cannot create executables 
See `config.log' for more details 

這是造成的config.log：

This file contains any messages produced by compilers while 
running configure, to aid debugging if configure makes a mistake. 

It was created by python configure 2.7, which was 
generated by GNU Autoconf 2.68. Invocation command line was 

    $ ./configure

見關於編譯項目的Emscripten wiki頁面，

http://kripken.github.io/emscripten-site/docs/compiling/Building-Projects.html

還有一個項目，編譯Python來Emscripten，empythoned，

https://github.com/replit/empythoned

我不知道它是最新的，但。
