Hello
I know that C++ is not officially supported but I wonder whether somebody else had the same problem. I can compile an example project with gcc (mingw32-make) and compilation is successful if I just add a c++ file to the list of source file in the make file. However I get compilation errors in cmsis_gcc.h as soon as I add any nordic related header file to the c++ file.
The include is wrapped in extern "C" {}. SDK is nRF5_SDK_17.0.0_9d13099
Would be nice to be able use C++ with arm gcc toolchain.
Here the error messages:

I'll appreciate any hints or comments.
