Here is the error:
-----------------------
Unable to locate 'mexopts.bat', and therefore cannot determine which compiler to use for simulation builds.
Use 'mex -setup' to select a supported compiler.
------------------------

i tried to run mex -setup command and this is what i got:

-------------------------------
Would you like mex to locate installed compilers [y]/n? y

Select a compiler:

[0] None

Compiler:
---------------------------------
i am using Windows 7 x64, i am not sure if this has anything to do with the error? iam trying to run a stateflow with S

Any help would be appreciated.

Thanks,

Ahmed Gabr

You need a supported C compiler on 64-bit windows. Assuming you are using
R2009b, have a look at:
http://www.mathworks.co.uk/support/compilers/R2009b/win64.html

If you are using Microsoft Visual Studio, pay particular attention to note
#6 on that page.

HTH,

Arnaud
