I have dev-lang/icc-11.1.071-r1 and sci-libs/ipp-11.1.072 from mainline portage installed. OpenCV's configure can find the ipp installation at /opt/intel/Compiler/11.1/072/ipp but not the IA32 libraries. Configure fails and it does not proceed with compilation. OpenCV will configure and compile just fine if the ipp use flag is not enabled. Reproducible: Always Steps to Reproduce: 1. Emerge media-libs/opencv-2.3.1a-r1 with ipp use flag enabled Actual Results: Configure fails to find IPP's IA32 libs, configure stops, and compilation does not take place Expected Results: Configure should find IPP's IA32, complete and proceed with compilation Portage 2.3.2-r2 (default/linux/x86/2008.0/desktop, gcc-4.6.2, glibc-2.14.1-r2, 3.2.5-gentoo i686)

From looking at the CMake files, the ebuild is detecting the IPP directory as "/opt/intel/Compiler/11.1/072/ipp" and then failing on either not finding ../ia32/ or lib/ia32 from there (probably the former, the CMake file has a conditional and I'm not sure which path it's taking). Can you confirm whether one of these exists?
I have /opt/intel/Compiler/11.1/072/ipp/ia32/lib/
Created attachment 306425 [details, diff] files/patch ok; this should do it. My system isn't finding the icc compiler for some reason so I can't actually emerge it. From the above, this line in the file OpenCVFindIPP.cmake is erroneous. If you don't know. add it to files/, then add it to the ebuild with epatch "${FILESDIR}"/opencv.patch in src_prepare(). It has two bites of the cherry and it got them both wrong. This makes it match your path you gave. Test, re-post
Cant test this because I cannot emerge icc right now (version in portage does not fetch)
Use flag has been masked, for lack of better options.
It appears the problem is not with OpenCV's ebuild. The environment variables which specify the library paths for ipp are installed incorrectly - at least with sci-libs/ipp-11.1.072. Please see https://bugs.gentoo.org/show_bug.cgi?id=426932 Setting the correct environment variables allows OpenCV's ebuild to find the libraries with no trouble.
Created attachment 319014 [details] files/OpenCV-2.3.1-OpenCVFindIPP.cmake.patch After a couple of days of revamped effort, I have solved the issue. The only environment variable which is actually checked is $IPPROOT. The other environment variables specifying the locations of the libraries appear to be ignored. The original patch did not address a secondary issue which caused a compile failure at 23% completion. I have corrected this secondary issue as well. There are two potential areas of concern. The first is that I have only confirmed that this works on my x86 system. I have not confirmed that it works on an amd64 system. The second is that my testing has only been done with sci-libs/ipp-11.1.072 which is in the 6.x series of IPP libraries. OpenCV's cmake script uses a different method of locating the IPP libraries depending on whether IPP is >=7.0, and my patch only affects the portion for <7.0. Therefore I do not know whether cmake will successfully find the libraries for IPP 7.0 or greater.
Created attachment 319016 [details, diff] files/OpenCV-2.4.2-OpenCVFindIPP.cmake.patch This is the same patch as above tailored to media-libs/opencv-2.4.2
