error: could not compile `latinimers` due to previous error

> Task :cargoBuildArm64 FAILED

FAILURE: Build failed with an exception.

(I tried building it from within Android Studio too and it's the exact same error)

It does look like libunwind should exist, according to

~ ls /home/mraof/.rustup/toolchains/nightly-x86_64-unknown-linux-gnu/lib/rustlib/aarch64-linux-android/lib/|rg unwind
libpanic_unwind-deb996301f6c12b9.rlib
libunwind-9bd9b1ea0ddb7756.rlib

[mraof]

Managed to fix this by installing the ndk via android studio before installing it via pacman, though it took enough finagling I can't be certain exactly what was the straw that fixed the camel's back

[TheAwesome98-Real]

installing the ndk in android studio didn't help for me, and i can't figure out what else is causing it since those files also exist for me
