USC_ec application does not compile in IPP 6.1.2.041

I am compiling on AMD 64 bit Vista-64 using visual Studio 2005. I am using the sample project file for echo cancellation. I am not able to link. I am using libs from emt64\\stublib and speech-codec\\lib\\win64 ipp_rta.lib.

What am I doing wrong.?

Looks to me like you've got an environment variable problem. I just successfully opened the same sample project in VS 2008 (had to convert from the existing project files) and did not experience any problems with the build.

Is your IPPROOT environment variable set to point to the installation directory? In a typical "standalone" install IPPROOT should be pointing to something like on a Vista 64 system:

C:\Program Files (x86)\Intel\IPP\6.1.1.035\em64t

or

C:\Program Files\Intel\IPP\6.1.1.035\em64t

The project files do reference the IPPROOT env variable.

Thanks . I fixed it. The problem was that I needed to choose x64 config in the VStudio Configuration manager.

I was using win32 on a 64 bit machine with emt64 package.
