SDL example cannot locate __gxx_personality_v0 at runtime #28
Description
It seems like the libSDL.so, when built for aarch64, doesn't properly link to android's libc++ (or libstdc++?).
zig build -Dtarget=aarch64-linux-android
adb install zig-out/bin/sdl-zig-demo.apk
When building for arm, it can't find android_getCpuFamily
zig build -Dtarget=arm-linux-android
adb install zig-out/bin/sdl-zig-demo.apk
I'm only using NDK version 28 and build-tools version 35.0.1. do either of those matter?
The minimal example seems to build. install, and run fine.
dumping the libSDL.so from the apk shows that it does not need libc++
objdump -p lib/arm64-v8a/libSDL2.so

and readelf shows that it does need __gxx_personality_v0

I can't really find anything online about __gxx_personality_v0 except to use gpp instead of gcc, which I assume is like using zig c++ instead of zig cc, but I'm not sure how to achieve that.
