You can see that to include the header, first, we use the name of the library (“my_roscpp_library”) followed by the name of the header we want to include (“my_super_roscpp_library.h”). Then we just call the function declared in the library header, sayHello(). Inside the CMak...
I am seeing an error marker in the cpp file. Steps to reproduce Create a new project from the sample_project template. Create the following test_function.c and test_function.h files. /* this is a test file */ #include <esp_system.h> void test_function_a(); ...

Another way to include paths in C++ is by using a macro. Macros are another type of function that can be used in place of an identifier or any other sequence of characters you want to represent as a single token.These functions are typically used for simple text replacements, such as ...
