编辑： Matt J 2013-9-28

Hi,

I have downloaded a set of functions for computing exact geodesic on a surface mesh from here : http://www.mathworks.com/matlabcentral/fileexchange/18168-exact-geodesic-for-triangular-meshes

I was trying to go through the examples provided by the author, but as one of the functions makes a call to 'loadlibrary' I get the following error:

??? Error using ==> loadlibrary at 279
Microsoft Visual C++ 2005 or 2008 is required to use this feature.

I installed Microsoft Visual C++ on my machine, but this error still persists. Any help would be greatly appreciated. Thank you.

So here is what I did:

mex -setup

Please choose your compiler for building external interface (MEX) files:

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

Select a compiler:

[1] Microsoft Visual C++ 2010 Express in c:\Program Files (x86)\Microsoft Visual Studio 10.0

[0] None

Compiler: 1

Please verify your choices:

Compiler: Microsoft Visual C++ 2010 Express

Location: c:\Program Files (x86)\Microsoft Visual Studio 10.0

Are these correct [y]/n? y

***************************************************************************

Warning: MEX-files generated using Microsoft Visual C++ 2010 require

that Microsoft Visual Studio 2010 run-time libraries be

available on the computer they are run on.

If you plan to redistribute your MEX-files to other MATLAB

users, be sure that they have the run-time libraries.

Trying to update options file: C:\Users\Anton\AppData\Roaming\MathWorks\MATLAB\R2010b\mexopts.bat

From template: C:\PROGRA~1\MATLAB\R2010b\bin\win64\mexopts\msvc100freeopts.bat

Done . . .

Warning: The MATLAB C and Fortran API has changed to support MATLAB

variables with more than 2^32-1 elements. In the near future

you will be required to update your code to utilize the new

API. You can find more information about this at:

Building with the -largeArrayDims option enables the new API.

So I guess it was able to locate the compiler. However, I am not sure if it was the 64bit one.

I tried running the above examples again, but still get the same error ...

Any idea what else I could try?

Hi Walter,

well, you could really help if you tried running one the examples (from above mentioned toolbox) on your machine. Does it work for you?

My MATLAB machine is Linux, not MS Windows.

For versions older than R2011a, Visual Studio Express (free) editions were not supported with LOADLIBRARY - the support was added in R2011a. However, it looks like this user has been able to use some clever tweaks to make even older versions work with the Express versions: http://www.mathworks.com/matlabcentral/newsreader/view_thread/281365
