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`"]

Out[2]= {}

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

  • $\begingroup$ 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? $\endgroup$

    $\begingroup$ Yes, for the Intel compiler it is strictly necessary. It works with the Express edition as well, at least I think so. $\endgroup$

    $\begingroup$ 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. $\endgroup$

    $\begingroup$ @jfklein It works, thank you. @Ajasja After defining $CCompiler = {"Compiler"->CCompilerDriver`IntelCompiler`IntelCompiler,"CompilerInstallation"->"C:\\Program Files\\Intel\\Composer XE 2011 SP1\\"}; now DefaultCCompiler[] returns CCompilerDriver`IntelCompiler`IntelCompiler. $\endgroup$ Commented May 24, 2012 at 10:03

    $\begingroup$ CCompilers[] only lists compilers that are seen to be valid installations. CCompilers[Full] will list all compilers supported on that $SystemID. $\endgroup$

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:

$CCompiler = {"Compiler" -> 
   "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.
