SpiderMonkey 1.8 rc1をMacに入れる

まず，NSPRを入れる．

チェックアウト
$ cvs cvs -q -d :pserver:anonymous@cvs-mirror.mozilla.org:/cvsroot co -r NSPR_4_8_4_RTM mozilla/nsprpub
$ cd mozilla/nsprpub

コンパイル＆インストール
$ ./configure
$ sudo make install

/usr/local以下にインストールされる

$ ls /usr/local/include/nspr
$ ls /usr/local/lib/libnspr*

次に，SpiderMonkeyを入れる．

ダウンロード
$ curl -O http://ftp.mozilla.org/pub/mozilla.org/js/js-1.8.0-rc1.tar.gz
$ tar xzfv js-1.8.0-rc1.tar.gz
$ cd js/src

コンパイル
$ make JS_DIST=/usr/local JS_THREADSAFE=1 BUILD_OPT=1 -f Makefile.ref

/usr/local以下に手動インストール
$ sudo mkdir /usr/local/include/js
$ sudo cp jsapi.h jspubtd.h jsutil.h jstypes.h jscpucfg.h jsotypes.h /usr/local/include/js
$ sudo cp jscompat.h jsproto.tbl jsconfig.h jslong.h Darwin_OPT.OBJ/jsautocfg.h /usr/local/include/js
$ sudo cp Darwin_OPT.OBJ/libjs.a Darwin_OPT.OBJ/libjs.a /usr/local/lib

下記サンプルをコンパイルしてみる．

コンパイルと実行．
