M1 support in ndk-build script

[JancyWeng]

在Mac M1上使用NDK

export NDK_HOME=/Users/xxx/Library/Android/ndk/android-ndk-r22
export PATH=$NDK_HOME:$PATH

然后运行 ndk-build 的时候报错 ERROR: Unknown host CPU architecture: arm64

是否是不支持Mac M1？

[hhb]

M1 native support is not ready yet. See #1299. In the mean time you can try to run ndk-build with rosetta2 like: arch -x86_64 /bin/bash -c ndk-build

@hhb how to resolve this issue.?

[DanAlbert]

Did you try using Rosetta?

[muhammadatifarif]

no rosetta for android studio.

[DanAlbert]

Rosetta is something you install yourself. It's part of macOS, not Studio.

You will still need rosetta for ndk-build for a little while longer as many of the components listed in #1299 still need fat binaries, but that fix will resolve an ndk-build issue with rosetta. Plan is to have everything in the NDK be fixed to not require rosetta by the time r24 reaches stable (and a lot will be backported to r23).

For the upcoming r24, we currently have these components as universal binaries: LLVM, make, python3, and shader-tools. The NDK package still needs yasm and simpleperf migrated. CMake and Ninja are shipped independently of the NDK, and they're in progress. (I have them building as universal binaries already, but we need to upgrade the CMake version in the SDK.)

[DanAlbert]

Because r23 doesn't have the fix yet. You can figure out what releases are still waiting for fixes by looking at the "projects" section of the bug.
