How to create a dll with Matlab Compiler?

Hi.

I am a new user of Matlab compiler and I would like to create a c++ shared library using library compiler. After exporting my main function in "Library compiler", I am not able to click on "Package" (the "package" button never turns green and is not active). Note that with the same code or main function I was able to create a standalone apps with Application compiler. Please what could be the problem?

Besides when I open the "Library compiler" I have the following messages:

Does it have a link to the difficulty I have to create the a .dll?

Thank you for your answers, Loic

[Walter Roberson]

You refer to creating a DLL with "MATLAB Compiler", but your tags say "MATLAB Compiler SDK". MATLAB Compiler SDK is the product you need to create a DLL since roughly the R2012b time frame (I would have to check the exact release); the facility used to be part of MATLAB Compiler but was moved to MATLAB Compiler SDK.

[Loic Wilfried Biakeu Njia]

It was a wording mistake, sorry. I indeed used Matlab Compiler SDK to create a DLL. I don't know for which reason I had those messages but now it is find. May be because I started first to build a standalone application, and then right after for the same script I tried to build the dll without closing the previous project (even if I changed the App from compiler to compiler sdk).

Anyway, thank you for the answer.
