Exa: Support for ARM64 version

[nlamirault]

Could you provide an ARM64 version in a next release ?
Thanks.

It looks like rust-cross can help with cross-compiling for ARM — the next time I make a new release I’ll see what I can do.

[0x3333]

I'm was looking for a version to run on my RBPi 3B+.

I boot up a Ubuntu Docker Image(docker run -it ubuntu /bin/bash) and run:

apt update
apt install -y git curl gcc-arm-linux-gnueabihf

pushd /usr/local/src && git clone https://github.com/ogham/exa.git && popd

curl https://sh.rustup.rs -sSf | sh
export PATH=$PATH:/root/.cargo/bin
rustup target add armv7-unknown-linux-gnueabihf
cat >>/root/.cargo/config <<EOF
[target.armv7-unknown-linux-gnueabihf]
linker = "arm-linux-gnueabihf-gcc"
EOF

cd /usr/local/src/exa
cargo build --release --no-default-features --features "default" --target=armv7-unknown-linux-gnueabihf

The binary will be in target/armv7-unknown-linux-gnueabihf/release folder:

$ file target/armv7-unknown-linux-gnueabihf/release/exa
target/armv7-unknown-linux-gnueabihf/release/exa: ELF 32-bit LSB shared object, ARM, EABI5 version 1 (SYSV), dynamically linked, interpreter /lib/ld-, for GNU/Linux 3.2.0, BuildID[sha1]=071f9344646fa0987b828ef0d22dc6a6938c119a, with debug_info, not stripped

Hope it helps.

Came here looking for an ARM release for the Pinebook Pro. I'll try compiling it tomorrow.

Easier method using @messense docker images for cross compiling:

# Clone exa
cd /tmp && git clone https://github.com/ogham/exa.git && cd exa

# Build using Cocker
docker run --rm -it -v "$(pwd)":/home/rust/src \
  messense/rust-musl-cross:armv7-musleabihf \
    cargo build --release --no-default-features --features "default"

[eggbean]

@0x3333 I just tried that on my RasPi and got this:

$ docker run --rm -it -v "$(pwd)":/home/rust/src \
>   messense/rust-musl-cross:armv7-musleabihf \
>     cargo build --release --no-default-features --features "default"

Any idea what's going here?

Has anybody got a static binary compiled on ARM that they could share?

@eggbean, my command is to cross-compile exa for Pi on an x86 machine... I just run it and it worked flawless.

Thanks, I misread. I didn't even realise that was possible. Cheers.

[eggbean]

@0x3333 Do you have this issue?

https://github.com/ogham/exa/issues/719

[0x3333]

@eggbean, yes I do have it...

[ickam]

@eggbean if you're looking for an armhf binary, it is actually available in debian repositories, although the version that they have is 0.8.0-2. For arm64 I had to compile it myself. I did it on a target machine and it worked, but I forgot to save the deb package that I made with cargo deb
I can still upload the exa binary directly from my path if you (or anyone else) need/s it, but you may need to resolve some dependencies.

@ickam Cross-compiling it using the method 0x3333 explained worked fine. Cheers.
