Request a new KPP feature:
to compile kpp on apple silicon based machines I would like to suggest to include in the makefile for Darwin :
ARCH := $(shell uname -m)
ifeq ($(ARCH), x86_64)
# Commands for Intel-based macOS
CFLAGS += -arch x86_64
else ifeq ($(ARCH), arm64)
# Commands for Apple Silicon-based macOS
CFLAGS += -arch arm64
else
$(warning Unknown architecture: $(ARCH))
endif
