解决ubench安装失败问题

想使用ubench测试CPU，但是一直安装存在问题。后查阅资料，请教群友及同事，最终解决。记录如下：

testcloud@computer9:~/Test/Ubench_1221/ubench-0.32$ ./configure

1.参考http://www.extmail.org/forum/thread-7882-1-4.html安装并打上了patch，但是问题没有解决，make时候又出错。

testcloud@computer9:~/Test/Ubench_1221/ubench-0.32$ patch -p0 < /home/testcloud/Test/Ubench_1221/ubench-patch

make: *** [ubench] Error 1

2.修改或者检查Makefile：

其中第14，15行：

另外第22行：

$(CC) $(CFLAGS) -o $@ $(objects) $(LDFLAGS)

然后重新make：

3.修改cpubench.c

第28行增加头文件：#include <stdio.h>

检查第74行：

4.执行：gcc -o ubench signals.o cpubench.o membench.o ubench.o -lm

5.检查makefile，并重新编译：

运行./ubench之后得出结果如下：

完成。
