Error trying to run compiled Fortran code

fixitben — Wed, 14 Sep 2016 22:18:06 GMT

I am running on fortran on a Linux box. When I compile it seems to compile fine. Using this command.

 ifort -mkl -o sesame1 *.f90

Then I try and run sesame1 using ./sesame1. I get the error below.

./sesame1: error while loading shared libraries: libmkl_intel_lp64.so: cannot open shared object file: No such file or directory

I am not sure why. I have manually exported the library to the LD_LIBRARY_PATH.

export LD_LIBRARY_PATH=/opt/intel/composerxe/mkl/lib/ia64/:$LD_LIBRARY_PATH

I have ran the command compilervars.sh. Still the same. I am not sure why it won't see the library.

Thanks

The command

The command

export LD_LIBRARY_PATH=/opt/intel/composerxe/mkl/lib/ia64/:$LD_LIBRARY_PATH

is incorrect unless you really have a Linux box with an Itanium CPU. Check the directory where the shared libraries are actually installed. The path will probably contain intel64, not ia64.

Thanks for your help. Soon

Thanks for your help. Soon after I posted this I realized my error. I am still not sure why the compilervars.sh and mklvar.sh doesn't load this path. Either way It works now. Thanks

Hello,

Hello,

Right, you may set it manually, or run the script with the CPU type option

>source mklvars.sh [intel64|ia32]

as MKL user guide https://software.intel.com/en-us/node/528500 mentioned:

It can set the INCLUDE, MKLROOT, LD_LIBRARY_PATH, MIC_LD_LIBRARY_PATH, MANPATH, LIBRARY_PATH, CPATH, and NLSPATH environment variables in the command shell using one of the script files in the bin subdirectory of the Intel MKL installation directory. The environment variable MIC_LD_LIBRARY_PATH specifies locations of shared objects for Intel® Many Integrated Core (Intel® MIC) Architecture

Best Regards,

Ying
