I want to use MKL library in Linux OS. First I set environment variable as exportLD_LIBRARY_PATH=/opt/intel/mkl/10.2.2.025/lib/em64t:$LD_LIBRARY_PATH. Then, complie the program: mpif90-omain.exeexample.F90-L/opt/intel/mkl/10.2.2.025/lib/em64t-I/opt/intel/mkl/10.2.2.025/include/-lmkl_scalapack_lp64-lmkl_blacs_intelmpi_lp64-lmkl_lapack-lmkl_intel_lp64-lmkl_intel_thread-lmkl_core-liomp5-lpthread There is no error when compling. When I run the program, it says: main.exe:errorwhileloadingsharedlibraries:libmkl_scalapack_lp64.so:cannotopensharedobjectfile:Nosuchfileordirectory I don/t know why, I strictly accord to the user's Guideof "Intel Math Kernel Library for Linux OS"(March 2009), I was completely confused and have been stumbled here for more than two weeks. Who can help me? Thanks very much!
