      Hi,
I am trying to build the most simple simulink model: constant source --> matlab function block (doing out = in) --> sink (out). 
When using matlab function block, at the step of buolding the model, I get an error... any ideas why? I am grateful for any suggestion.

Here is the error:

myModelName =

test

 +++++ opening model test & setting parameters...
 +++++ building model test ...

### Starting xPC Target build procedure for model: test ??? Error using ==> tlc_c at 174 Error using ==> create_file_name_info at 267 unexpected compiler

Error in ==> RTW.makertw.make_rtw at 267 buildResult = tlc_c(h,...

Error in ==> make_rtw at 22 buildResult = h.make_rtw(varargin{:});

Thank you!

Have you set up your C compiler and target settings in xPC Target Explorer? Have tried running xpctest? You should go through the Getting Started section of the documentation before doing anything else.

So mex -setup solved the issue. (sets up C comp. for Host PC, separately from the Target PC).

Thank you very much!

Excellent. Yes, you need a compiler when using the MATLAB Function, which needs to be set up separately from the one used for xPC Target (although it could be the same compiler).
