Build fail on MacBook M1

[zanmato1984]

General Question

It's a brand new MacBook M1 I just obtained, with barely nothing installed.

Clang version:

Apple clang version 13.0.0 (clang-1300.0.27.3)
Target: arm64-apple-darwin21.4.0
Thread model: posix
InstalledDir: /Library/Developer/CommandLineTools/usr/bin

CMake version:

cmake version 3.23.2

Build tiflash with:

cmake .. -DCMAKE_BUILD_TYPE=DEBUG -DENABLE_TESTS=ON
make -j

Two errors occurred:

Undefined symbols for architecture arm64:
  "_GetAarch64FeaturesEnumName", referenced from:
      _AddFlags in list_cpu_features.c.o
  "_GetAarch64FeaturesEnumValue", referenced from:

I think I was following every step in the build doc, but I don't know why it failed.

Waiting for workaround.

Any update? @solotzg @SchrodingerZhu

I have been on some personal stuffs since Thursday. I will be looking into the CPU features specific problems this weekend.

[fuzhe1989]

Some updates:

• For the first issue (cpufeatures): change cpu feature behavior for M1 #5394 works for me.
• For the second issue (protoc): manually brew install protoc and ensure using nightly rustc works for me.
