You need to be very careful that you have followed all of the steps outlined above such as having Visual Studio 2008 Pro SP1 installed with the 64 bit compilers. That error may be occurring because it is attempting to use a 32 bit compiler, but I can't remember entirely. I encourage you to visit the mathworks.com forums and read up on MATLAB documentation if you are still having difficulty. Hi Tobias,

I have successfully set this up numerous times with different versions of MATLAB and on different machines. I encourage you to carefully review my post and perform the steps. Then explain to me specifically what the problem is if you are still having difficulty. You may need to install Windows SDK. I also recommend seeking advice on mathworks.com in the forums as people who develop MATLAB regularly post and check there. Hi Xin,

I am sure that I chose full install during the install of visual studio. But I got the following in MATLAB: >> !set VS VS90COMNTOOLS=C:\Program Files (x86)\Microsoft Visual Studio 9.0\Common7\Tools\ >> !"%VS90COMNTOOLS%..\..\VC\vcvarsall.bat" Setting environment for using Microsoft Visual Studio 2008 x86 tools. I think MATLAB is using the x86 compiler instead of x64. Do you know how to check the x64 compiler? I have re-installed the visual studio several times, and it still goes like this. Thanks a lot for your help. Xin Hi Todd,
Thank you very much for your reply.

Thanks a lot for your help.

When you open MATLAB you need to make sure you browse to the correct folder so that you can see the files on the left sidebar in MATLAB default view. If you are using 64 bit Windows did you make sure you did a full install and/or installed the 64 bit compilers. Did you make sure you compiled both the header and source files correctly into the dll? MATLAB needs the header file and the dll file. Hi Xin

I also installed Microsoft Visual Studio 2008 Pro SP1 and MATLAB 2009b on my computer. But When I tried to use 'loadlibrary', it always came out an error that 'fatal error C1083: Cannot open include file:'test.h': No such file or directory' Do you have any idea where the problem is? Any help would be appreciated. Xin Thank you very much for your sharing.
