Need help in R2010b using the build_ada_sfcn command.

The mex -v -ada command executes correctly in version R2007a (.mexw32) and R2010b (.dll)

Tech Note 1821 - (Developing and Building S-Functions for Simulink® that Incorporate Ada Code) said the mex -v –ada command will not be supported past R2010b.

Tech Note 1821 says to use this command, build_ada_sfcn

But I get and error using build_ada_sfcn, can you tell me why??

This is the successful mex -v -ada PW_Build_20_1R.ads

>> mex -v -ada PW_Build_20_1R.ads Warning: The -ada option to mex is not recommended. Instead, use the method provided in Tech Note 1821, which includes a MATLAB function and interface files that provide the same capability.
