I'm running Mathematica 9 on a 64 bit Windows 8.1 laptop. I'm having no luck getting C compilation to work.





The package did load successfully, as $Packages shows CCompilerDriver entries and




I have the following compilers installed:

  • Microsoft Visual Studio Professional 2013
  • Intel C++ Composer XE

Is it possible for you to install MS VS 2012 and try again to set up the compiler ? –  Sektor Feb 4 '14 at 14:54
AFAIK under Windows the PATH to the Visual Studio compiler is not set system wide. Can you try to add VC to your PATH and restart Mathematica? –  halirutan Feb 4 '14 at 14:55
@halirutan Oh, I had no trouble running VS 2012 and compile str8 after install :) –  Sektor Feb 4 '14 at 14:59
@halirutan I don't remember the details, but it does not find the location of VS using PATH. I think it uses another environment variable ... –  Szabolcs Feb 4 '14 at 16:28
I don't have access to Windows at this moment, but I looked at the VS compiler driver, and it looks like it find the location of the compiler based on the VS110COMNTOOLS environment variable. There are lines like installPath["2012"] := installPathFromEnvironment["VS110COMNTOOLS"] for 2005, 2008, 2010 and 2012, but not 2013. I don't know how your version of VS indicates its location, but you could try CCompilerDriver`VisualStudioCompiler`Private`installPath["2013"] := ... or whatever is appropriate for you compiler, and trying again. –  Szabolcs Feb 4 '14 at 16:33

Visual Studio 2013 is not supported out of the box by Mathematica 9.0.1. To fix this,

  • Navigate to AddOns\Applications\CCompilerDriver within the Mathematica installation directory.

  • Back up VisualStudioCompiler.m as we're going to modify it.

  • Open the file and search for the line starting with installPath["2012"]

  • Add the following line below it:

    installPath["2013"] := installPathFromEnvironment["VS120COMNTOOLS"]
  • Search for the line $VisualStudioVersions = {"2012", "2010", "2008", "2005"} and add "2013" at the beginning, like this:

    $VisualStudioVersions = {"2013", "2012", "2010", "2008", "2005"}
  • Save the file, restart Mathematica, and try again.

Well, it seems that this was a hit and run question. The OP has disappeared. If anyone can test if this solution is working, please comment so we can finalize or delete the answer. –  Szabolcs Feb 5 '14 at 18:15
I can confirm that this does not fix the issue. Think I will have to reinstall VS2012 now, crap! –  RunnyKine Feb 8 '14 at 19:39
@RunnyKine Before you do that, let's experiment a bit ... does the VS120COMNTOOLS environment variable exist on your system? What is its value? –  Szabolcs Feb 8 '14 at 19:43
It exists, I can't see the full value but it's C:\Program Files (x86)\Microsoft Visual Studio 12.0 ... –  RunnyKine Feb 8 '14 at 19:50
@RunnyKine OK, did you actually edit the file I referenced in the post, the way I described? (Make a backup of the original and put the backup in some other directory.) If not, please try actually editing, and make one more change: look up the line starting with $VisualStudioVersions and add "2013" at the beginning of that list. Let's see if it works when both changes are done. –  Szabolcs Feb 8 '14 at 19:54
