问题1：如果   gcc  安装失败 需要按照失败的提示，重新安装。

问题2：cannot find -lbz2
解决方案：
apt-get install libbz2-dev

问题3：Makefile:13: *** missing separator.
	解决方案：打开文件Makefile 13行加个TAB分隔

问题4：

bsdiff.c:(.text.startup+0x2b0): undefined reference to `BZ2_bzWriteOpen'

collect2: error: ld returned 1 exit status
<builtin>: recipe for target 'bsdiff' failed

解决方案：
 把下载好的bzip2库拷到bsdiff的文件夹 
修改bsdiff  bspatch 文件 ，添加如下倚赖
#include "bzip2/bzlib.c"
#include "bzip2/crctable.c"
#include "bzip2/compress.c"
#include "bzip2/decompress.c"
#include "bzip2/randtable.c"
#include "bzip2/blocksort.c"
#include "bzip2/huffman.c"
