Hi all I have test tor x86 android binary on x86 android device, it cann't work with --enable-rust , rust_welcome_string & rust_str_get called by C code correctly, but in C code, rust_str_get always return zero length string, it's very strange. after read https://github.com/rust-lang/libc#platforms-and-documentation, I found that arm-linux-androideabi is the only one supported target on android platform. it may be the root cause of the issue on x86-android platform. -- Thanks PGP Fingerprint: F7BA D6CE 6592 77C7 0D2E 3BD5 5479 A15E B305 B8FE
