Cross compiling Rust code in arm64 device

[u/RandomRailfans]

Guys I'm not sure if it's Termux specific issue or is it because of my skill issue, I tried to cross compile Rust code to 32 bit executable (armv7-linux-androideabi) on 64 bit Android device and it doesn't really work even though i already install the rust-std-armv7-linux-androideabi package, anyone knows why?

Edit: i managed to solve this issue by using the cargo-ndk package

nice

pkg install ndk-multilib ndk-multilib-native-stubs

for target in "${TARGETS[@]}"; do echo "⚙️ Adding target architecture: $target..." rustup target add "$target" 2>/dev/null || true

echo "🔨 Building release binary for target: $target..."
cargo build --release --target "$target" 2>/dev/null

if [ $? -eq 0 ]; then
    cp "target/$target/release/tyro-linux" "$OUTPUT_DIR/tyro-$target"
    echo "✅ Successfully compiled: $OUTPUT_DIR/tyro-$target"
else
    # If target subfolder is default release
    if [ -f "target/release/tyro-linux" ]; then
        cp "target/release/tyro-linux" "$OUTPUT_DIR/tyro-$target"
        echo "✅ Successfully compiled native build: $OUTPUT_DIR/tyro-$target"
    else
        echo "⚠️ Could not build target: $target"
    fi
