Can this be built on Mac M1? #60

Closed ChenZhongPu closed 1 year ago

ChenZhongPu commented 1 year ago

According to the README, Mac M1 is supported.

... an ARM processor with NEON instructions ...

Makefile uses aarch64 as the condition for test:

ifeq ($(PROCESSOR), aarch64)
# for 64-bit ARM processors
CFLAGS = -fPIC -std=c99 -O3 -Wall -Wextra -pedantic -Wshadow -D__ARM_NEON__

But in fact what uname -m returns on my Mac M1 is arm64. What about the following condition:

ifneq ($(filter $(PROCESSOR), arm64 aarch64),)

Thanks for the report.

I have had, myself, an M1, an M1 Pro and an M2 -based machine over the years. It has always worked. Apple defines __ARM_NEON__ by default so there is no need to specify it.

Please reopen a new issue which provides, at a minimum, a detailed description of the build error you are encountering.
