Nodeやio.jsのpreバージョンをビルドしてnvmから使う

Last updated at Posted at 2014-12-30
git clone git@github.com:joyent/node.git
cd node
./configure --prefix=~/.nvm/versions/v0.13.0-pre
make -j10
make install
git clone git@github.com:iojs/io.js.git
cd io.js
./configure --prefix=~/.nvm/v0.11.15-pre
make -j10
make install

nodeの方は現在のmasterブランチをビルドするとv0.13.0-preになり、io.jsはv0.11.15-preになる。このバージョン番号をうまくあわせないと認識できないっぽい。

https://github.com/creationix/nvm/blob/master/nvm.sh#L161
このへん読むとv0.12.0を境に配置ディレクトリが変わるっぽいので配置先もあわせた。

でもnodeはv0.12ブランチのが進んでいる?のでこっちのがいいかもしれない。
https://github.com/joyent/node/commits/v0.12

$ nvm ls
    v0.10.31
    v0.11.14
    v0.11.15-pre
->  v0.13.0-pre
    system
Node.js
$ nvm use v0.13.0-pre
$ node --v8-options | grep harmony
  --harmony_typeof (enable harmony semantics for typeof)
  --harmony_scoping (enable harmony block scoping)
  --harmony_modules (enable harmony modules (implies block scoping))
  --harmony_symbols (enable harmony symbols (a.k.a. private names))
  --harmony_proxies (enable harmony proxies)
  --harmony_collections (enable harmony collections (sets, maps))
  --harmony_generators (enable harmony generators)
  --harmony_iteration (enable harmony iteration (for-of))
  --harmony_numeric_literals (enable harmony numeric literals (0o77, 0b11))
  --harmony_strings (enable harmony string)
  --harmony_arrays (enable harmony arrays)
  --harmony_maths (enable harmony math functions)
  --harmony_promises ((dummy flag, has no effect))
  --harmony (enable all harmony features (except typeof))
io.js
$ nvm use v0.11.15-pre
$ node --v8-options | grep harmony
  --es_staging (enable all completed harmony features)
  --harmony (enable all completed harmony features)
  --harmony_scoping (enable "harmony block scoping" (in progress))
  --harmony_modules (enable "harmony modules (implies block scoping)" (in progress))
  --harmony_arrays (enable "harmony array methods" (in progress))
  --harmony_classes (enable "harmony classes (implies block scoping & object literal extension)" (in progress))
  --harmony_object_literals (enable "harmony object literal extensions" (in progress))
  --harmony_regexps (enable "harmony regular expression extensions" (in progress))
  --harmony_arrow_functions (enable "harmony arrow functions" (in progress))
  --harmony_tostring (enable "harmony toString" (in progress))
  --harmony_proxies (enable "harmony proxies" (in progress))
  --harmony_strings (enable "harmony string methods")

--harmony_classes --harmony_arrow_functionsオプションなどがio.jsの方がV8が新しいので入っていることがわかる。

見分けつかなくなるのでaliasはっておくのがよさそう

nvm alias iojs v0.11.15-pre
