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.

Try running "mex -setup" on your MATLAB. Is it able to automatically locate Visual C++? If not, you may be missing x64 compilers (by default only the 32-bit compiler is installed): http://www.mathworks.com/support/solutions/en/data/1-6IJJ3L/?solution=1-6IJJ3L

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

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

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?

Maybe the error needs to be taken literally: that for some reason it requires C++ 2005 or 2008, whereas you are using C++ 2010. For example perhaps it requires SDK 6.1 for some reason.

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

Thanks for clearing that up

So going back to a supported C++ 2008 would have worked. Too bad no-one happened to suggest anything helpful along those lines...
