hello, good morning everybody! i have some doubts about this, i'm using an ATMEL SAMD2 microcontroller, i'm new to this compiler and they let me handle this micro in keil uvision. I tried to make a library handling C++ language but I get these errors and this is the code:
I hope you can see the screenshots I captured, otherwise I leave the errors that marked me the compiler:

I want to know if the microcontrollers of the ATMEL(Microchip) family support C++ language programming on keil uvision or do I have to use their ATMEL STUDIOS interface?
I hit this recently, too (on the SAMC21). ARMCLANG is built from Clang (naturally), and Clang addresses C++ DR2229 (see the list of C++ defects here). I'm not aware of a clang switch that can turn off the DR2229 fix.
The solution I chose was to use C for the functionality that needed access to the things defined in samc21.h, and call those functions from my C++ code.
Hello, Adam Lins! Thank you, I reviewed the document, so you don't add the SAMC21 library as such? or what do you call it? I didn't quite understand the solution.
I'm using the SAMC21 libraries -- I just don't include the SAMC21 header file in any C++ files, to avoid the compiler complaining about the header. I define functions in C files that use the information from the header (e.g., timer register access structures), and call those "helper" functions from the C++ code.
