...sed in every Arduino Uno. My main motivation being that I hope to be able to use a couple of STL containers, <functional> and <type_traits> on the MCU. Not sure though if this can be reached by going via the clang route. Getting back to the compilation: when I run clang with both both -nostdlibinc (which makes it necessary to point clang to the header file location via -isystem /opt/avr/avr-libc/avr/include) and --gcc-toolchain I can compile the minimum example code. clang++ --target=avr -nostdlibinc -isystem /opt/avr/avr-libc/avr/include --gcc-toolchain=/opt/avr/avr-gcc -mmcu=atmega328p...

Hi everyone, I've been wondering how to correctly build clang/LLVM for the AVR target architecture. Unfortunately documentation is very scarce (or outdated or I didn't find it) and while I've been able to build clang/LLVM for AVR I'm still falling short of compiling an actual binary for the MCU. Here are the steps I've undertaken so far: git clone
