help! me too

This is a fairly old release. Does this issue persist on 3.17.x ?

This is a fairly old release. Does this issue persist on 3.17.x ?

My project needs this version

Unfortunately, supporting all old releases on new hardware and new toolchains is not a thing we likely to spend resources on.

./google/protobuf/stubs/atomicops_internals_macosx.h:157:52: error: unknown type name 'Atomic64'; did you mean 'Atomic32'?
inline Atomic64 NoBarrier_AtomicIncrement(volatile Atomic64* ptr,
^~~~~~~~
Atomic32

Does anyone have an idea?

I meet the same question. To resolve it, I have added
#elif defined(__arm64__) #define GOOGLE_PROTOBUF_ARCH_ARM 1 #define GOOGLE_PROTOBUF_ARCH_64_BIT 1
before
#else #error Host architecture was not detected as supported by protobuf
in src/google/protobuf/stubs/platform_macros.h for version 2.5.0
, then I made install successfully. Maybe you can try it.

Hi @DapengShi

I am able to resolve the issue with your comment. Thank you very much.

vi src/google/protobuf/stubs/platform_macros.h

#elif defined(__arm64__)
#define GOOGLE_PROTOBUF_ARCH_ARM 1
#define GOOGLE_PROTOBUF_ARCH_64_BIT 1

Add the above code before the following line:

#else
#error Host architecture was not detected as supported by protobuf
#endif

Hello @DapengShi

I can install it on the Mac M1 chip with your changes. Thanks a lot.

It works. Thanks~
