https://devzone.nordicsemi.com/f/nordic-q-a/92203/zephyr-and-using-c-codeI&#39;m considering transitioning a product codebase to the nRF family (nRF52 or nRF53). It&#39;s Arduino code, with lots of C++ code. As in the cpp_synchonization example provided with Zephyr, I can compile code with a C++ class defines in the CPP file.en-USTelligent Community 13Thu, 22 Sep 2022 16:59:20 GMThttps://devzone.nordicsemi.com/thread/387558?ContentTypeID=1Thu, 22 Sep 2022 16:59:20 GMT137ad170-7792-4731-bb38-c0d22fbe4515:6a5b1354-14d2-41aa-b350-a0ebe578721aDavid Elvig <p>Beautiful!</p> <p>Fixed with your suggestions.</p> <p>I needed to also add&nbsp;<em><span style="text-decoration:underline;">extern &quot;C&quot; {</span></em></p> <p><em><span style="text-decoration:underline;">...<br />}</span></em></p> <p>around the prototype in a c header file I was calling.</p> <p>It all compiles and links!</p> <p>Source updated <a href="https://github.com/Davidelvig/DaveLED1">here</a> if anyone wants to look. &nbsp;I&#39;ll leave this test repo live for a while.</p> <p>Thanks!</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/387496?ContentTypeID=1Thu, 22 Sep 2022 12:28:50 GMT137ad170-7792-4731-bb38-c0d22fbe4515:4007197c-3a8c-4e19-8aa3-3c22dfcb24efwilu<p>main.c file should be renamed to main.cpp to&nbsp;change the compiler to g++ instead of gcc.<br /><br />Do not add&nbsp;src/TestCPP.hpp as a target source, header files are not compiled.<br /><br />In main.c file add extern &quot;C&quot; before void main() function.<br /><br /></p><div style="clear:both;"></div>
