If your library is in sharedlib/libipp.a, for example, append -l ipp. The linker is standard gnu ld, it has no idea what libraries you want from the library search path.

I do icc test.cc -L/opt/intel/ipp/sharedlib -I/opt/intel/ipp/include -o test The .h seems to be found OK. It recognizes the special IPP structures. But, when an actual IPP function is used it has an error. What should I do??
