compile error on android target

[bigdogs]

Code

Just build a simple project, with command cargo +nightly build -Z build-std=std,panic_abort -Z build-std-features=panic_immediate_abort. It works for ios, but failed for android target.

seems panic on here in source code.

Meta

rustc --version --verbose:

<version>

It seems that cc can’t find your compiler, have you set your NDK properly?

[bigdogs]

@name1e5s Is there need any other setups to make android targets works? It's ok if I just run cargo build --target <android>, but when I add some features to make binary small, it will fail with above error. e.g. carg build --target <android> +nightly build -Z build-std=std,panic_abort -Z build-std-features=panic_immediate_abort. so what's the difference between that ?

Triage: Thank you for reporting. Please provide a minimal reproducer so that others can reproduce your problem. Thanks!
