Opencv+IPP+VC6

Hi dear IPP team members,

I am david and a industrial device software engineer.

Now we have a plan to using IPP to achieve the speed up work of our software.

our software has a long history (over 20years) and until now we are still using a very old version of opencv lib(0.9.7). I search online and find, it seems old version of opencv can auto load IPP function. I download a IPP6.0 and install it, and add it to the system path. but it seems the software can not load IPP as I thought. do you guys have any idea about my case, please let me know, I will be very grateful for your kind help.

It is a little difficult

It is a little difficult because I find there is not enough information on the net. please give me your idea whatever it works or not.

Could you share your

Could you share your configuration log of OpenCV?

Before configuring opencv, IPP related environment variables should be set such that opencv can detect IPP.

你好，你所说的配置log是指什么信息？目前我们想用opencv100的版本替代097的版本，速度有一定提升，但是和原来的程序存在一定兼容性的问题。目前来看097的版本无法自动加载IPP优化，而100的版本可以实现自动加载IPP优化。

执行./configure的时候会输出编译器

执行./configure的时候会输出编译器，各种依赖库等等的检测结果，那个里面可以看有没有检测到IPP，或者有没有去检测IPP。

有可能opencv 097太老了不支持IPP。

你们也可以搜索一下opencv的文件夹看看有没有跟IPP相关的文件，如果没有的话基本上就是不支持IPP了。
