Intel® C++ Compiler for Linux* - Issues running Intel® C++ Compiler for Intel® 64-based application

If you see the following error message when running the compiler 10.1 and earlier version:

mcpcom: error while loading shared libraries: cannot open shared object file: No such file or directory compilation aborted for /tmp/hello.cxx (code 127)

It is because the Intel® C++ Compiler for applications running on Intel® 64 architecture requires the following 32-bit (IA-32) C and C++ runtime libraries:,,, and

The requirement on 32-bit (IA-32) libraries is due to the compiler and various components being 32-bit applications, and dynamically linking to these libraries. The above error message is confusing as it doesn't indicate that the IA-32 version of libstdc++ library is required. To avoid this problem, install the 32-bit (IA-32) versions of these libraries. Most Linux* distributions for Intel® 64 architecture will install these 32-bit libraries by default.

This article only applies to Intel® C++ Compiler 10.1 and earlier versions.  Intel® C++ Compiler 11.0 for Intel® 64 is a 64-bit application, which doesn't require 32-bit libraries.
