Error while loading library

I am trying to load a shared library from the sample code provided in the matlab documentation.
addpath(fullfile(matlabroot,'extern','examples','shrlib'))
if not(libisloaded('shrlibsample'))
loadlibrary('shrlibsample')
end
But when it tries to load the library i get an error:
Error using loadlibrary
The MATLAB program file describing your library could not be found, possible Perl or file system error.
Any help is appreciated.

Which MATLAB version are you using?
Have you installed a compiler and used
mex -setup
?

I had a very similar problem: When I tried,
addpath(fullfile(matlabroot,'extern','examples','shrlib'))
if not(libisloaded('shrlibsample'))
loadlibrary('shrlibsample')
end
I got:
Error using loadlibrary
Too many output arguments.
Following @Philip Borghesani's suggestion, I found that it was the "perl" command that was broken (returning too many outputs).
The problem turned out to be that MATLAB's built-in perl.m was shadowed by a perl.m in a toolbox I had downloaded from a third party.

Something quite odd is going on, This error is caused by a timeout waiting for the prototype file to be visible to MATLAB after supposedly successful creation. I have only questions and suggestions.
- If your current directory is not writable by you try changing to one that is.
- Make sure your tempdir is writable and the disk is not full
- If nether of these helps or is the problem try using the m_filename option to loadlibrary to specify the name and location of the prototype file that will be generated.
- If all else fails contact support.

I got the same problem, when I tried the perl command I got as a reponse an empty answer, while when I use it on a computer where the loadlibrary works, I get the expected hello. So, how do I fix perl now?

Any responses from Matlab Support? Have the same error and tried all steps here.

For a response from Mathworks Support you need to open a technical support case. This resource, MATLAB Answers, is replied to by volunteers, most of whom do not work for Mathworks.
