ここで emscripten のチュートリアルを読んでいます。
ここまでで、ソースをダウンロードし、.emscripten 設定ファイルを適切に設定しました。
「python.cc.js」と「python.html」を作成/出力するために必要な一連のemccコマンドは何ですか? emscripten を試したことのある開発者からのヒントを歓迎します。
これが私の .emscripten ファイルです:
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]
そして、ここemconfigure ./configureに私が実行しているコマンドがあります:

結果の config.log は次のとおりです。
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
