Thread Subject: R2009b Visual Studio 2008 / Win7 x64

I installed Visual Studio 2008 Express in my Win7 x64 and cannot get the compiler to compile a mex file. I tried all suggestions here and other places, and still it does not work. I also installed the trial version of Visual Studio 2008.

This is the error I am getting after configuring mex:

 Error: Could not find the 64-bit compiler. This may indicate that the
         "X64 Compilers and Tools" or the Microsoft Windows Software
         Development Kit (SDK) is not installed. To build 64-bit MEX-files
         Microsoft Visual C++ 2008 requires that these two packages are
         installed properly.

and this is the error I am getting when execute mex yprime.c

Error: Could not find the compiler "cl" on the DOS path.
         Use mex -setup to configure your environment properly.

As the error message suggests, you need to select "X64 Compilers and Tools"
when installing Microsoft Visual Studio. This is not selected by default.
Have a look at the following for more info:

This option does not exist in either Visual Studio 2008 express or visual studio 2008 trial! Also, it does not exist in the Windows 7 SDK .net 3.5 that I installed before. It will be nice if Mathworks engineer would reverify that.

Did you actually look at the page I mentioned, in particular note 6, which
should point you to the following solution?

I got the same problem here. Win7 x64, You do not have those options
mention in the page http://www.mathworks.com/support/solutions/en/data/1-6IJJ3L/index.htm

I installed Visual Studio 2008 Express and Visual Studio 2008 Full
including the Win 7 SDK and the amd64 folder does not exist. It looks
like Mathworks engineers did not test R2009b on Win7 for all options.

So, I am not the only one that experiences this problem. It will be nice if a Mathworks engineer will fix those issues.

There is no issue to fix, you need to install the correct components for
Visual Studio to work.

Actually, there is an issue to fix, but who's issue is the question. For those who have selected to install the x64 compilers, it is in the following directory in Win7 (C:\Program Files (x86)\Microsoft Visual xxxx\VC). So the issue, it seems, is that Matlab will not look in the x86 Program Files folder for the x64 compilers. I have the same issue, and I know for a fact the compilers are on the computer.

We just need a way to point Matlab to the x86 directory, or possibly try installing the compilers in the x64 Program Files directory.

Sure, in the mean time, I found this...

http://www.mathworks.com/matlabcentral/fileexchange/18508-microsoft-visual-studio-2008-mex-and-mbuild-setup-files

Download the files, then place the appropriate x64 files (both mex and mbuild) in the directories listed in the .txt file, then run mbuild -setup again. For me, this detected the x64 compiler. I have not tried compiling anything so I can't verify that it works, and the comments seem to be mixed....but it's a start.

Hi Arnaud,

I have a Win7 x64 machine running R2009b and I have the same problem. On the supported compilers page, we are greeted with this footnote:

"To use Microsoft Visual Studio with MATLAB on a 64-bit platform, you must select "X64 Compilers and Tools" when installing Microsoft Visual Studio. This is not selected by default. Microsoft Visual Studio 2008 Express and Professional Editions also require that the Microsoft Windows Software Development Kit (SDK) is installed properly. For more information, see Solution 1-6IJJ3L."

Now, this is misleading, since there is no option to select "x64 Compilers and Tools" when installing *VS*, at least from my experience - only options to install Silverlight and something for SQL.

At first, I had just installed VS and then tried using >> mex -setup again to receive the same error (that MATLAB cannot find the x64 compiler). Then, I read the solution page (1-6IJJ3L)

http://www.mathworks.com/support/solutions/en/data/1-6IJJ3L/index.html?solution=1-6IJJ3L

So, I installed the MS SDK today. During the installation of the SDK, I was able to select Visual C++ Compilers, which included the x64 compliers (so, the option to install x64 compilers comes with the installation of the SDK, not VS!). During this process I installed the options:
Developer Tools > Visual C++ Compilers
and
Developer Tools > Windows Headers and Libraries

Unfortunately, after doing this, I still can't get MATLAB to find the x64 compilers. Also, the SDK appears to have installed correctly, as the following file appears as wanted (see the solution page).

C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\bin\amd64\cl.exe

So, I'm not sure what to do at this point.

Sorry for the quick double-post on this subject, but I found something interesting.

Previously, I had installed MS Visual Studio 2008 first, then the SDK, as described here:
http://www.mathworks.com/support/solutions/en/data/1-6IJJ3L/index.html?solution=1-6IJJ3L

However, MATLAB was still unable to find the x64 compiler.

Then, today, I reinstalled MS VS, or rather, I ran the setup again and "repaired" the installation. To my surprise, it appeared that more x64 options were being installed than before. Perhaps this installation recognized the MS SDK installation and decided to install more x64 stuff on its own. Also to my surprise, MATLAB afterwards found the x64 compiler. Does the SDK (only Developer Tools > Visual C++ Compilers) need to be installed *before* Visual Studio?

At any rate, at least the Simulink Accelerator appears to be working now. Unfortunately, I'm having trouble using Embedded MATLAB blocks in Simulink and I cannot run mex on the example in the solution page above. When I run the following code:

copyfile(fullfile(matlabroot,'extern','examples','mex','yprime.c'))
mex -v yprime.c
yprime(1,1:4)

I get at the output:

Unfortunately, a search on this error yielded only the following page:
http://www.mathworks.com/matlabcentral/newsreader/view_thread/166600

I will see if I can get MATLAB to find 'mt' as well.

For further documentation, when I try to use Embedded MATLAB, I get the following error when I click the 'Build' button from an Embedded MATLAB block:

Embedded MATLAB Interface Error: Error calling generated SFunction, attitude_control_sfun

Sometimes, if I try to run the simulation (after the build fails, with the error dialog still open), it will produce the following error:

This error seems to have something in common with the post
http://www.mathworks.com/matlabcentral/newsreader/view_thread/270052
where the author is also having problems running MATLAB on x64 Win7.

Hello,

I had the same problem. It seems that "Microsoft Windows SDK for Windows 7 and .NET Framework 4" released in May 2010 have a bug : the mexopts.bat file is not correctly generated . I uninstall this version and install "Microsoft Windows SDK for Windows 7 and .NET Framework 3.5 Service Pack 1" from that link http://www.microsoft.com/downloads/details.aspx?FamilyID=c17ba869-9671-4330-a63e-1fd44e0e2505&displaylang=en . If it still doesn't work, I can send you my mexopts.bat file. I tested on two different PC ( Windows 7 64 bit) and works very good.
Please let me know if this solves your problem.

Best regards,
Iulian

Chris,

I had a very similar problem (ie after installation mt.exe was not recognized).

Solution is to install the developer tools in SDK as well. As far as I can tell, you did not choose to install the developer tools so you do not get mt.exe in your SDK installation.

I hope this helps

Hi Mustafa,

As you might see from my post above (Date: 5 May, 2010 14:31:20, Message: 11 of 15), I installed
Developer Tools > Visual C++ Compilers
and
Developer Tools > Windows Headers and Libraries
from the SDK, which apparently inclues mt.exe (maybe just the VC++ compilers?)

As it turns out, the response above yours, (From: Iulian, Date: 25 May, 2010 18:03:21, Message: 14 of 15) seems to be the right respose - my mexopts.bat file was not being generated properly. Instead, I was able to solve the problem using the solution posted on
http://www.mathworks.com/matlabcentral/fileexchange/22689),
after hacking around with it a little bit.

I'm glad you were able to solve your problem. I think I wasn't clear in my response. Just to clarify, the solution to my problem was to install

Developer Tools> Windows Development Tools

in addition to Developer Tools>Compilers and Developer Tools>Headers.

Before I installed that I did not have an mt.exe anywhere on my machine.

Hey, I tried pretty much every solution on this page, and I'm not having any luck. I'm using windows 7 x64 and matlab r2009b. So, could you send me your mexopts.bat file?
My email should be available on my profile. Thank you so much!

Hello David and other users,
   I am having exactly the same problem you giuys have with the 2009b(x64) Matlab compiler problem with the downloades Microsoft C++ 2010 express and SDK 7.1. My problems has not been solved. I cannot select the compiler from the matlab and don't know how to find the exact that matlab is looking for. May you guys have any solution already? Would you please help me?
   I am also getting the exact error message like this:

   Error: Could not find the compiler "cl" on the DOS path.
          Use mex -setup to configure your environment properly.
  
  
   C:\PROGRA~1\MATLAB\R2009B\BIN\MEX.PL: Error: Unable to locate compiler.
  
 ??? Error using ==> mex at 221
Unable to complete successfully.

Any suggestion!?
Thanks so mcuh.

 If it still doesn't work, I can send you my mexopts.bat file. I tested on two different PC ( Windows 7 64 bit) and works very good.

Could you send me your mexopts file and a quick readme on where to place it please. My Email is avail on my profile.

Hi Iulian,
I also have the similar problem and tried everything described in this post. Could you send me your mexopts.bat file. That's the only other option left for me to try as of now. My email id is sageorge@usc.edu

Thanks in advance

> > I had the same problem. It seems that "Microsoft Windows SDK for Windows 7 and .NET Framework 4" released in May 2010 have a bug : the mexopts.bat file is not correctly generated . I uninstall this version and install "Microsoft Windows SDK for Windows 7 and .NET Framework 3.5 Service Pack 1" from that link http://www.microsoft.com/downloads/details.aspx?FamilyID=c17ba869-9671-4330-a63e-1fd44e0e2505&displaylang=en . If it still doesn't work, I can send you my mexopts.bat file. I tested on two different PC ( Windows 7 64 bit) and works very good.
