[求助]好心人帮忙看下问题所在。。。

红色为问题所在，在我的电脑上就会出现如下错误：

sample8.c - 3 errors
52, 5 Undeclared identifier 'IIRFilterPtr'.
52, 18 syntax error; found 'identifier' expecting ';'.
52, 18 Undeclared identifier 'filter_information'.


去掉52行编译通过，连接又出问题，

1 Project link error
Undefined symbol '_FFT' referenced in "sample8.c".


但是，我在另一台机器上就没有问题。可以通过。

是不是因为我们的CVI版本不同，或者是包含的库不同？

怎么解决啊？？谢谢啦！！！！！！

二边的程序是一样的吗?有没有一些文件没有拷贝过来的呢?最好压缩一个上传,这样调一下比较容易找到问题所在!
