I am compiling mex files using matlabs lcc compiler. All files compile sucesfully, but the linking breaks. It complains about undefined reference to all IPP functions I have used. I have only used those in the ipps part, i.e signal processing. I have inlcluded the switch -L"C:Program...ia32stublib" -libpath"C:Program...ia32stublib" and added ipps.lib to the list of files to link with. Do any of you have any clues to why the linker is not finding the symbols to link with?
