Hi, I am trying to use cpp based codes, but the build result returns some syntax errors. Is it possible to use cpp syntax with IDF?

It is possible. There is even a small amount of C++ code inside the IDF internals themselves.

Neil Kolban has some C++ samples/snippets/utils here: https://github.com/nkolban/esp32-snippe ... /cpp_utils

STL is available. But there are some restrictions, for example exception support is disabled.

Can you please be more specific about the errors you are seeing?

There are also a couple of sample skeletons for C++ available here ...

Thank you for the kind replies, ESP_Angus and N. Kolban.
I am using basic idf and I have built my project, after just including some .cpp files in other .c files.
Am I doing wrong?? If it needs other procedures or configurations, could you please let me know?

Can you post some of your code or the exact errors? It's hard to guess from just a rough description like this.

Make sure any C++ symbols (functions, etc.) called from C are marked with 'extern "C"' in their C++ declarations.

EDIT: Also files in C++ syntax must be in a .cpp file, so the build system knows to run a C++ compiler not a C compiler.

Who faced this?
