Ubuntu下安装oprofile后执行出错!

[china_clear]

我用的ubuntu是嵌入式,芯片为Xscale270.
Linux内核为:2.6.14.7-intc1-bs3
我把oprofile在交叉编译环境编译好后,手工COPY到目标机上,编译出的执行文件都可以执行,只有opcontrol是文本文件,不能执行.
错误信息为:
./opcontrol: line 1652: printf: not found
./opcontrol: line 1652: printf: not found
./opcontrol: line 1652: printf: not found
./opcontrol: line 1652: printf: not found
mount: mounting nodev on /dev/oprofile failed: Device or resource busy
cpu_type 'unset' is not valid
you should upgrade oprofile or force the use of timer mode
./opcontrol: line 1678: printf: not found
./opcontrol: line 1678: printf: not found
./opcontrol: line 1678: printf: not found
Unknown option "". See opcontrol --help

我搞了几天了没搞定,请大家帮忙看看!有什么方法可解决?谢谢了!

再问一下,不用opcontrol能对程序进行性能分析吗?
怎么执行命令?

[china_clear]

编译了一个printf,可以了!
不过又出现了一个错误:
/mnt/usr/local/bin/opcontrol: line 1810: seq: not found


有哪位帮忙解决一下!谢谢了!

seq先简单，自己写了一个！
现在的问题是，取不到数据，不知为什么？

有没有人提示一下？
