Can't build for i686-linux-android

[igrep]

Problem Summary

I'm trying to build an Android app depending on wasmtime-api.
But building wasmtime-api for i686-linux-android fails due to an error by i686-linux-android-ar.exe though building for the other targets (aarch64-linux-android and armv7-linux-androideabi) successes.
Isn't Android supported yet?

Steps to Reproduce

cargo new wasmtime-android --lib
cd wasmtime-android

And edit dependencies etc. of Cargo.toml:

[dependencies]
[target.'cfg(target_os="android")'.dependencies]
jni = { version = "0.13.1", default-features = false }
wasmtime-api = { git = "https://github.com/CraneStation/wasmtime.git", rev = "43b761ef5f2d8a4c6bf4aab82922f053d1852d59" }

[lib]
crate-type = ["dylib"]

Then run cargo build --target i686-linux-android

Output by cargo build --target i686-linux-android

...

It seems like you mixed up ar and linker for android.

[igrep]

Oh, thank you! I wrote my .cargo/config in a wrong way!
Changing the target.i686-linux-android section into below fixed!

Have you compiled wasmtime successfully for Android ?

[igrep]

No. I successfully avoided the error, but I gave up after that because Cranelift didn't support i686 (at least then).

[tkkcc]

@igrep have you tried some other technics to run wasm on android x86 abi.

[igrep]

@tkkcc Unfortunately, I've never successfully run wasm on Android x86. Once I run wasmer on Android x86*-64* by https://github.com/iijlab/wasmonandroid. But it's about 64bit, and I guess it doesn't work with the latest wasmer.

[tkkcc]

Thanks for reply. I just tried a bit, and fail too. I tried wasmer llvm-compiler feature, as llvm-sys support static linking, it may be work. but i can't even run the example on my pc.

[cfallin]

We still do not support 32-bit x86 (#1980), aka i686; if anyone would like to contribute support, that would be fantastic, but unfortunately no one has had time so far. 64-bit x86 (x86_64) works fine for Linux/Windows/macOS/FreeBSD/...; if there are issues building for Android/x86_64 and someone has a patch we'd be interested in that too.
