这个SNAPHU的安装花费了我很多的时间，一直在调试snaphu，但总是提示bash错误，段错误，很是烦人，今天小结一下。

SNAPHU 安装：

   # http://www-star.stanford.edu/sar_group/snaphu/snaphu-v1.4.2.tar.gz 

     tar zxvf snaphu-v1.4.2.tar.gz

     cd snaphu-v1.4.2/src

     make

     make install

     cd ../bin

     cp snaphu $MY_BIN  (复制可执行文件到MY_BIN文件下)

#### 编译的snaphu不可用 编译有问题

yu@yu-H34:~/apps/ROI_PAC_3_0_1/snaphu-v1.4.2/src$ sudo make

cc  -O3      -c -o snaphu_tile.o snaphu_tile.c

cc  -O3      -c -o snaphu_solver.o snaphu_solver.c

cc  -O3      -c -o snaphu_io.o snaphu_io.c

snaphu_io.c: In function ‘WriteConfigLogFile’:

    fprintf(fp,"# Log file generated %s",ctime(t));

cc  -O3      -c -o snaphu_util.o snaphu_util.c

cc  -O3      -c -o snaphu_cost.o snaphu_cost.c

cc  -O3      -c -o snaphu_cs2.o snaphu_cs2.c

cc  -O3    \

snaphu.c \

snaphu_tile.o snaphu_solver.o snaphu_io.o snaphu_util.o snaphu_cost.o snaphu_cs2.o  \

-o ../bin/snaphu \

-lm

上述的编译可能有问题，不能正常使用。

运行程序时出错：

.............

单独试用snaphu出错：

去改make_offset.pl 里的参数，把精配准的参考窗口大小和搜索窗口大小64，8 改为128，64等
