Description
- Download Android NDK r22
- Build with
export ANDROID_NDK_ROOT=/path/to/android-ndk-r22 ./build.sh --os android --arch x64 -c Release
Expected:
Build succeeds
Actual:
EXEC : error : /Applications/Xcode_12.5.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/ranlib: archive library: libSystem.Native.a the table of contents is empty (no object file members in the library define global symbols) [/Users/alklig/work/dotnet-runtime/runtime-bugs/src/libraries/Native/build-native.proj]

Build fails while linking libSystem.Native.a with:
Note that it's Xcode's linker that is complaining. So something about the toolchain detection is not picking up the linker from the NDK and falling back to whatever it finds on the PATH.
Possibly see #51876 which attempted to support r22 apparently did not get everything.
I have this in ndk/source.properties
Pkg.Desc = Android NDK
Pkg.Revision = 22.0.7026061
Have not tried the latest r22b 22.1.7171670 at this time.
