Dockerfile for aarch64

[ghost]

I'm on an M2 Mac, and I've been trying to create a Dockerfile for aarch64, because the anchor build command takes over 15 minutes on my machine when using the current amd64 image.

I figured out how to build the Solana CLI tools from source (there's no aarch64 Linux binary), but now I'm stuck with the following error (when running anchor build):

/root/.rustup/toolchains/bpf/bin/cargo: error while loading shared libraries: libz.so.1: cannot open shared object file: No such file or directory

apt-file search libz.so.1 told me it belongs to zlib1g, but I already have it installed (the aarch64 version).

I managed to resolve the previous error

#16 228.0 qemu-x86_64: Could not open '/lib64/ld-linux-x86-64.so.2': No such file or directory

by running

# apt-get install libc6-amd64-cross && mkdir /lib64 && ln -s /usr/x86_64-linux-gnu/lib/ld-linux-x86-64.so.2 /lib64/ld-linux-x86-64.so.2

but maybe that wasn't the correct approach?

Anyway, here's my Dockerfile (based on the official amd64 one):

# Build a dummy program to bootstrap the BPF SDK (doing this speeds up builds).
RUN mkdir -p /tmp && cd /tmp && anchor init dummy && cd dummy && anchor build

The last command (anchor build) causes the above-mentioned errors.

The reason I'm doing this is because I want to make Solana development easier with my command-line tool create-solana-starter (a Grizzlython hackathon submission). Installing all the needed tools (Rust, Solana, Anchor, etc.) locally can be a hassle, so I would like to give users the option to use Docker instead.

Would appreciate any advice on how to proceed from here!

I got around the libssl issue by just manually installing the version it wanted, although I can't confidently say that it's safe or not:

I have the same issue and it seems that Rust Solana toolchain is x86_64 getting downloaded even on aarch64 Linux system. This is what I see in my aarch64 container (running on M2 Mac):

node@9fd3ed47fbfe:/tmp$ file /home/node/.rustup/toolchains/stable-aarch64-unknown-linux-gnu/bin/cargo
/home/node/.rustup/toolchains/stable-aarch64-unknown-linux-gnu/bin/cargo: ELF 64-bit LSB pie executable, ARM aarch64, version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux-aarch64.so.1, for GNU/Linux 4.1.49, with debug_info, not stripped
node@9fd3ed47fbfe:/tmp$ file /home/node/.rustup/toolchains/bpf/bin/cargo
/home/node/.rustup/toolchains/bpf/bin/cargo: ELF 64-bit LSB pie executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux 3.2.0, BuildID[sha1]=8ce82da00b04ebeffef3123908ca46cc96f735ee, with debug_info, not stripped

What I need to figure out now is why is that x86_64 toolchain downloaded - whether it's Anchor or Solana scripts doing that.

OK, it's cargo-sbf-build doing that. It installs https://github.com/solana-labs/platform-tools here:

https://github.com/solana-labs/solana/blob/8c860e98949efafee878acfac9da67b0bf927cac/sdk/cargo-build-sbf/src/main.rs#L601-L607

And there are no binaries for linux-aarch64, the only aarch64 build is for macOS:

https://github.com/solana-labs/platform-tools/releases/tag/v1.37

There is an issue about that anza-xyz/platform-tools#66.
