[Prepare SpiderMonkey24 with Universal Binary]

1. Extract SpiderMonkey source.
  $ tar jxvf mozjs-24.2.0.rc2.tar.bz2
  $ export PATH_TO_SPIDER_MONKEY=$(pwd)/mozjs-24.2.0

2. Build SpiderMonkey for i386.
  $ cd ${PATH_TO_SPIDER_MONKEY}/js/src/
  $ mkdir obj_i386
  $ cd obj_i386
  $ AR="ar" CFLAGS="-arch i386" CXXFLAGS="-arch i386" LDFLAGS="-arch i386" ../configure --target=i386-apple-darwin10.0.0 --disable-shared-js --prefix=${PATH_TO_SPIDER_MONKEY}/dist/i386 && make && make install

3. Build SpiderMonkey for x86_64.
  $ cd ${PATH_TO_SPIDER_MONKEY}/js/src/
  $ mkdir obj_x86_64
  $ cd obj_x86_64
  $ AR="ar" CFLAGS="-arch x86_64" CXXFLAGS="-arch x86_64" LDFLAGS="-arch x86_64" ../configure --target=x86_64-apple-darwin10.0.0 --disable-shared-js --prefix=${PATH_TO_SPIDER_MONKEY}/dist/x86_64 && make && make install

4. Copy headers from x86_64.
  $ cd ${PATH_TO_SPIDER_MONKEY}
  $ mkdir ./include
  $ cp -R ./dist/x86_64/include/* ./include/

5. Make header file compatible with both i386 and x86_64.

Modify <PATH_TO_SPIDER_MONKEY>/include/mozjs-24/js-config.h, line 45.
from:
  #define JS_BYTES_PER_WORD 8
to:
  #if defined(__i386)
  # define JS_BYTES_PER_WORD 4
  #endif
  #if defined(__x86_64)
  # define JS_BYTES_PER_WORD 8
  #endif

6. Merge libraries.
  $ cd ${PATH_TO_SPIDER_MONKEY}
  $ mkdir  ./lib
  $ lipo -create ./dist/i386/lib/libmozjs-24.a ./dist/x86_64/lib/libmozjs-24.a -output ./lib/libmozjs-24.a

[Build UnMHT for QuickLook]

1. Replace SMDIR variable in rules/Makefile.common.

from:
  SMDIR=/Users/arai/projects/spidermonkey24
to:
  SMDIR=<PATH_TO_SPIDER_MONKEY>

2. Replace ARCHS variable in rules/Makefile.common.

from:
  ARCHS=-arch x86_64 -arch i386 -isysroot /Developer/SDKs/MacOSX10.7.sdk
to:
  ARCHS=-arch x86_64 -arch i386 -isysroot <PATH_TO_SDK>

3. Build.
  $ make

4. Install into your Library Folder.
  $ make install
