HINT:
1.在执行./bootstrap.sh时遇到gcc版本过低问题：
checking if compiler is new enough... no
configure: error: compiler is too old; GCC 4.9 or later and Clang 3.3 or later are supported
解决方法：Ubuntu 14.04 更新gcc版本至4.9.2（http://www.linuxdiyf.com/linux/20175.html）
2.在执行make -j4的时候遇到gcc编译器内联错误("make -j4" failed in the dir p4c/build)
g++: internal compiler error: Killed (program cc1plus)
Please submit a full bug report,
with preprocessed source if appropriate.
See <file:///usr/share/doc/gcc-4.9/README.Bugs> for instructions.
make[1]: *** [unified-sources-p4c_bm2_ss-0.o] Error 4
make[1]: *** Waiting for unfinished jobs....
make[1]: Leaving directory `/home/wasdns/p4c/build'
make: *** [all] Error 2
原因：内存不足。
解决方法：将命令替换为
$ make -j2
3.执行make check的时候，会有大量的test failed，大多数是P4 14的test，目前尚未解决这个问题：
