this is so jank

STM32 seems so very not designed to work with C++, but you can absolutely make it work.

This project should compile from C++ as long as your arm-none-eabi-g++ is new enough... works on my machine anyways

Try this

Also try this list of ARM toolchain downloads

Change this part of Makefile below line 79 if you're not me:

#ifdef GCC_PATH
GCC_PATH = $(HOME)/.arm-gcc/bin
CC = $(GCC_PATH)/$(PREFIX)gcc
CXX = $(GCC_PATH)/$(PREFIX)g++
AS = $(GCC_PATH)/$(PREFIX)gcc -x assembler-with-cpp
CP = $(GCC_PATH)/$(PREFIX)objcopy
SZ = $(GCC_PATH)/$(PREFIX)size
#else
#CC = $(PREFIX)gcc
#AS = $(PREFIX)gcc -x assembler-with-cpp
#CP = $(PREFIX)objcopy
#SZ = $(PREFIX)size
#endif
HEX = $(CP) -O ihex
BIN = $(CP) -O binary -S

to this:

ifdef GCC_PATH
CC = $(GCC_PATH)/$(PREFIX)gcc
CXX = $(GCC_PATH)/$(PREFIX)g++
AS = $(GCC_PATH)/$(PREFIX)gcc -x assembler-with-cpp
CP = $(GCC_PATH)/$(PREFIX)objcopy
SZ = $(GCC_PATH)/$(PREFIX)size
else
CC = $(PREFIX)gcc
AS = $(PREFIX)gcc -x assembler-with-cpp
CP = $(PREFIX)objcopy
SZ = $(PREFIX)size
endif
HEX = $(CP) -O ihex
BIN = $(CP) -O binary -S
