Follow these steps to invoke the Intel® C/C++ Compiler from the command line:

1. Open a command prompt from the Windows* Start menu:
   Intel(R) Software Development Tools » Intel(R) C++ Compiler... » C++ Build Environment...
   
   To build from a regular DOS command prompt you will need to set the Compiler’s build environment variables first. You can set the build environment by executing the “iclvars.bat” which is located in the [intelc-install-dir]\[IA32|EM64T|IA64]\Bin directory in the Compiler’s installation directory tree.
   
   
2. Invoke the compiler as follows:
   icl /c [options... ] inputfile(s) [ /link link_options ]

   icl will always use the options set in icl.cfg. “icl.cfg” is located in the same directory as “iclvars.bat”.

3. Invoke the linker as follow:
   xilink [options... ] inputfile(s)

   Example:
   > icl /c /O2 hello.c
   > xilink hello.obj
