How to create a C++ project ? (Cpp project)
Hi,
You can either convert your existing C project to C++ (by right click on project then “Convert to C++”), or create a new project by choosing “C++ project” instead of “C project”.
However a C++ project is also a C project and the default main.c is still a C file (as are also the ST-provided libraries); you can just rename it as main.cpp (and correct it as it may not be a valid C++ file if you added incompatible C code). You can also include new C++ files in your project and they will be compiled by the C++ compiler; however, don’t forget to declare the functions that must be called from C code as extern "C"
The main difference is that the linker will use the C++ linker, even if you only include C files; note that if your C++ code must include C-compatible header files, these must, typically in a #ifdef c_plusplus
section declare all C functions as extern "C"
.
For example you can start your C header files by
#ifdef c_plusplus extern "C" { #endifand terminate them by
#ifdef c_plusplus }; #endif
