Intel® C++ Compiler for Linux* - Error while loading shared libraries: [shared lib]: cannot open shared object

If this error message references an Intel shared runtime library, such as, then this implies that the Linux* loader was not able to locate the library. First check that you have the Intel lib directory in your LD_LIBRARY_PATHenvironment variable. However, this can still be a problem when running a program where a new shell is created to run the program (such as MPICH). To fix this problem, link the Intel provided libraries statically with the -static-libcxa (for 10.x compiler and earlier versions only) or -static-intel flags or add the -rpathlinker option so the executables can find the libraries at runtime, for example:

icpc test.cpp -Xlinker -rpath -Xlinker <path to Intel libraries>

Path to Intel libraries depends on where you install the Intel compiler. The default paths to Intel libraries look like
9.1 compiler for IA-32: /opt/intel/cc/9.1/lib
9.1 compiler for Intel 64: /opt/intel/cce/9.1/lib
10.1.017 compiler for IA-32: /opt/intel/cc/10.1.017/lib
10.1.017 compiler for Intel 64: /opt/intel/cce/10.1.017/lib
11.0.069 compiler for IA-32: /opt/intel/Compiler/11.0/069/lib/ia32
11.0.069 compiler for Intel 64: /opt/intel/Compiler/11.0/069/lib/intel64

Note that anyone using a binary compiled with the -rpath option will need those libs to exist in that directory path as well, so you may have to redistribute the Intel provided libraries with your application.
