How to setup mex in Win 8

Is it the same to set up mex in Windows 8 as it in Windows 7? I tried SDK for Win 7, but it does not work. Where can I find SDK for Win 8? Thank you for your help

[Jan]

Could you elaborate "it doesn't work", please?

Same issue. What is a valid mex compiler for R2012b (or 2012a) on Windows 8? I have tried the following: Windows SDK 7 (it claims a newer version of .net is already installed and so skips that part), Windows 8 SDK, Visual Studio Express 2012 for Desktop (and for Metro). Whenever I try "mex -setup", it cannot find any valid compilers.

[Michael]

Update: I got it to recognize the compiler by first installing an earlier SDK: http://www.microsoft.com/en-us/download/details.aspx?id=3138 and then installing the newer one: http://www.microsoft.com/en-us/download/details.aspx?id=8279

Hi,

Was having this issue. This is mostly because you have the Visual C++ 2010 Redistributable Package for x86 and x64 installed in your computer. This prevents windows from installing the 7.1v of the SDK.

I solved it by going to control panel and uninstalling the Visual C++ 2010 Redistributable Package for x64 and x86 and then installing the Microsoft SDK 7.1.

After that you should be able to run mex -setup and it should detect the sdk and everything will be fine.

Hope it helps!

I have done like what you said.. now the error is Making simulation target "similartopaper_sfun", ...

C:\Users\user\Downloads\slprj\_sfprj\similartopaper\_self\sfun\src>call "\..\..\VC\vcvarsall.bat" AMD64 The system cannot find the path specified.

Thanks Benzun, worked like a charm !

You need to install the Windows SDK 7.1 for Matlab 2012b even under Windows 8. See: http://www.mathworks.com/support/solutions/en/data/1-FPLDGV/

The installation of the SDK7.1 under Windows 8 fails, when you have a newer MSVC 2010 redistributable installed. So uninstall this at first. See: http://support.microsoft.com/kb/2717426.

If this works, please ask the technical support to add this information on the list of supported compilers.

Is there any other free 64 Bit alternative under Windows?

I still have problems about setting up mex in my computer. It seems like Matlab 2012a don't support SDK 8.0, but Win 8 don't support SDK 7.1. What should I do to set up mex in Matlab 2012a under Windows 8......

[Jan]

Please explain why you assume, that Win8 does not support the SDK7.1.

[Juhua Huang]

Because I tried. Can you install sdk 7.1 in win8? Please let me know if you can. I will think if it is other reasons that I can install sdk 7.1

I am experiencing the same issue.

Here the error given when I try to install it on my Win 8, R2012b:

14:12:49 27 April 2013: [SDKSetup:Error] Config_Products_Install: Windows SDK Setup (failed): Installation of the "Microsoft Windows SDK for Windows 7" product has reported the following error: Please refer to Samples\Setup\HTML\ConfigDetails.htm document for further information.

When I installed the SDK 8, then I get this:

>> mex -setup

Welcome to mex -setup. This utility will help you set up a default compiler. For a list of supported compilers, see http://www.mathworks.com/support/compilers/R2012b/win64.html

Please choose your compiler for building MEX-files:

Would you like mex to locate installed compilers [y]/n? y

I also find myself in need of a (free) mex compiler that works with 64 bit Windows 8 and MATLAB 2012b?

If u r not able to solve the issue using the previously told method, Follow this...this might help u..FOR WINDOWS 8,64 bit Step 1: Install microsoft SDK 7.1 in compatibility mode as told below (a)after the required file is downloaded from net, right click on the driver and select properties (b)select the compatibility tab,click the compatibility mode check box to select it (C)select the previous version of ur OS(i did as windows XP,SP2) (d)click OK now try to install the setup..

STEP 2:Now building the mex-files in matlab environment..... After installing microsoft SDK 7.1, in matlab 2012a (if u r using it) type "mex -setup" in the command window. list of the installed compiler will b displayed and select microsoft SDK 7.1 from the list..

 Now u can use the C/C++ files,Mex files,,,,,,

i have intalled viual studio 2015 and SDK 7.1 and still am facing this error..

>> mex -setup
Error using mex
No supported compiler or SDK was found. You can install the freely available
MinGW-w64 C/C++ compiler; see Install MinGW-w64 Compiler. For more options, see 
http://www.mathworks.com/support/compilers/R2015b/win64.html

[Walter Roberson]

Did you install VS 2015 Professional, or did you install VS 2015 Express? It needs the Professional version.

To get the SDK 7.1 to work on Windows 8.*, you will need to be sure that .NET 4.0 gets installed, which can be slightly tricky on Windows 8 (which has .NET 4.5 installed)

[naadiya khudabux]

yeah i have installed vs 2015 community version.. can u please share the link to download vs professional

Sorry that is outside my experience.
