In the C/C++ options i don&#39;t see the compiler option for the preferred language when I open a project form the SDK15. when I create a test project, I can choose whether theen-USTelligent Community 13Tue, 01 Mar 2022 08:40:47 GMThttps://devzone.nordicsemi.com/thread/355449?ContentTypeID=1Tue, 01 Mar 2022 08:40:47 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e1d9afdd-fea3-447e-942d-48e021532703Einar Thorsrud<p>Hi,</p> <p>The nRF5 SDK is not tested with C++ compilers, it is not officially supported, and we know it use some constructs that are not valid C++.

That said, it should be possible to build your application files as C++ and the SDK files itself as C, but you may see a variety of issues. See for instance <a href="https://devzone.nordicsemi.com/f/nordic-q-a/4180/c-development-using-nrf51-sdk-on-keil/14946#14946">this old</a> post.</p> <p>PS: The <a href="https://www.nordicsemi.com/Products/Development-software/nRF-Connect-SDK">nRF Connect SDK</a> supports C++.</p><div style="clear:both;"></div>
