I wish to try the trial version of the latest Intel C++ Compiler for Windows with Mathematica. I have downloaded the current version of Intel® C++ Composer XE 2011 for Windows and installed only the "Intel C++ Compiler" component from this package. But Mathematica does not recognize it:

In[1]:= Needs["CCompilerDriver`"]
CCompilers[]

Out[2]= {}

How to configure Mathematica to use the Intel C++ Compiler?

Make sure you have installed the 64 bit tools for Visual studio (if you are on a 64 bit system). You did install visual studio right? – Ajasja May 23 '12 at 15:02
@Ajasja At least when using the Microsoft compiler, it's not strictly necessary to install Visual Studio. The Windows SDK with the command line compiler will suffice. But the Intel compiler I have never used on Windows. – Szabolcs May 23 '12 at 15:03
@Ajasja I use 32 bit Windows XP. I have not installed Visual Studio. Is it strictly necessary? – Alexey Popkov May 23 '12 at 15:04

Yes, for the Intel compiler it is strictly necessary. It works with the Express edition as well, at least I think so. – Ajasja May 23 '12 at 15:08

This Intel version 12 is not supported, and that's why CCompilerDriver is not automatically detecting your Intel compiler. Until I have a chance to look into this, you could go into AddOns/Applications/CCompilerDriver/IntelCompilerWindows.m and replace ICPP_COMPILER11 with ICPP_COMPILER12. This may work only superficially, but it would be the fastest thing for you to try. – Joel Klein May 24 '12 at 2:24

Mathematica 8 automatically detects Intel version 11, but not Intel version 12 which was released later.

In order to use the Intel 12 compiler, you'll need to set $CCompiler to point CCompilerDriver to where you've installed the Intel compiler:

Needs["CCompilerDriver`"]
$CCompiler = {"Compiler" -> 
    CCompilerDriver`IntelCompiler`IntelCompiler, 
   "CompilerInstallation" -> "E:\\IntelCompiler"};

You can put this in a kernel initialization file, such as $UserBaseDirectory/Kernel/init.m so you don't need to evaluate it every time you start Mathematica.

This should now Just Work in Mathematica 9. – Joel Klein Nov 30 '12 at 3:18
