simulink matlab function block build error

      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

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.

[Istvan]

Yes, I did. I can run on my xpc any model. The problem only occures when I have the Matlab Function block in my model....

Istvan

[Arnaud Miege]

OK, have you run mex -setup? Also, can you post the code of your MATLAB Function block?

[Istvan]

Note To configure your C compiler for the xPC Target software, use the xPC Target Explorer interface (see “Configuring the xPC Target Host PC for Your C Compiler” on page 2-19). Be aware that the mex -setup command does not set the C compiler for the xPC Target product.

[Istvan]

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

Thank you very much!

Istvan

[Arnaud Miege]

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).

Thanks friends. It was extremely helpful for me too.
