| 1) For the boost 1.39, we can compile 32-bit boost library using following command: | |
| $ ./bjam -a address-model=32 architecture=x86 variant=debug threading=multi link=shared runtime-link=shared | |
| the most important flag is: "address-model=32 architecture=x86", if only set the address-model to 32, the gcc compiler still can't compile 32bit library. we must also set the architecture to x86 |

###checkout the thrift-0.8.0
$ cd thrift
$ git checkout thrift-0.8.0
###download the ubuntu core image
download the ubuntu core image like:
$ wget http://releases.ubuntu.com/15.04/ubuntu-15.04-snappy-amd64-generic.img.xz
