How do I get this working? about execution-spec-tests

Apologies, we've wrote on the README.md that the required go-ethereum version should be v1.10.13, but currently to create all test fixtures (and run all test fillers) you will need to use the most up-to-date go-ethereum master branch.

This can't be it, because I'm using geth 1.10.26:

qbzzt1@spec-tests:~/execution-spec-tests$ evm --version
evm version 1.10.26-stable-e5eb32ac
qbzzt1@spec-tests:~/execution-spec-tests$ 

[spencer-tb]

That release doesn't work me as well, as I believe it was released last November. The most up-to date master branch works for me built from source 😄

evm version 1.11.0-unstable-55f41d19-20230126

Similarly, the branch used in our release should work. Hope this helps, I'll make a change to the README.

I want to use the latest spec tests (I plan on adding to them, after all), so I'll just use the latest master. Any special things I need to do to compile geth?

[qbzzt]

Thank you, it works now. I assume that after I get it working I run, for example, fixtures/vm/dup/dup.json with retesteth?

Great! Yeah that sounds correct.

Although you have it working I am going to leave this here for future reference:

Here is a fast way to build geth from source in order to get the most up to date evm binary:

git clone https://github.com/ethereum/go-ethereum.git && cd go-ethereum
make all

To add the built evm binary to PATH, the most flexible option is to create a symlink to the binary. I use linux so for me this is:

ln -s build/bin/evm /usr/bin/evm

This allows you to change branches and re-build the evm binary on the fly.

Thank you.
