Anchor test without AVX2 CPU

Question

After initialising a project with anchor init, when I run anchor-test, it gives me this message at the last.

Unable to get recent blockhash. Test validator does not look started. Check .anchor/test-ledger/test-ledger-log.txt for errors. Consider increasing [test.startup_wait] in Anchor.toml.

The expected output at last should be the transaction hash but I don't get it.

When I use solana-test-validator it returns Aborted(Core Dumped). It seems like my CPU is not AVX2 compatible for which I am not able to run solana-test-validator.

The project is instructing me to build from source.

What to do now?

Sounds like you'll need to build solana-test-validator from source! This isn't very hard to do thankfully, and the steps go:

• Install Rust:

$ curl https://sh.rustup.rs -sSf | sh
$ source $HOME/.cargo/env
$ rustup component add rustfmt

• Install build dependencies, for Ubuntu:

$ sudo apt-get update
$ sudo apt-get install libssl-dev libudev-dev pkg-config zlib1g-dev llvm clang make

• Download the source code:

$ git clone https://github.com/solana-labs/solana.git
$ cd solana

• Build the test validator:

$ cargo build --bin solana-test-validator --release

• Run it:

$ ./target/release/solana-test-validator
