Issue with Embedded Coder Target for Arduino

I am following this MathWorks File Exchange Link. I am having problem while running the myarduino_blink.slx demo.

My MATLAB version is R2015a, and I am using an Arduino Uno. I ran the file setup_custom_target_arduino.m after changing the relevant directory listing and the arduino version in the m file, and I got the output of Arduino on COM 3, which was correct.

After this, I checked the Simulink Library Browser and I had the Custom C/C++ Target Arduino Library will all its modules. Now when I simulate the model, I get the following error:

Error in S-function 'myarduino_blink/Digital Output':
S-Function 'sfunar_digitalOutput' does not exist

Kindly help me out, what could I have done wrong?

Update 1

Ok, I solved the "does not exist" problem. Apparently, no MEX compiler was installed. So I installed the Windows SDK, then re-ran the m file and now I am able to generate the .mex64 files. Now I run into another problem, when I build the simulink model, it gives this error:

Build procedure for model: 'myarduino_blink' aborted due to an error

How to solve this?

setup_custom_target_arduino.m calls build_all_sfunctions.m which should compile all of the S-Functions in the blocks directory. It looks as if that hasn't occurred for some reason. Check in the blocks directory that each of the S-Functions has a .c, .tlc (both of which come with the package) and a .mex64 (which is the compiled version of the .c generated by build_all_sfunctions.m) file.

If they are not there then the setup hasn't executed correctly, and you'll need to compile all of the S-Functions. If they are there then you most likely have some sort of path issue (although since you say you can see the library in the library browser this seems unlikely).
