undefined: abi.ConvertType for go file generated from solidity

[janus]

Hi there,

Please note that this is an issue tracker reserved for bug reports and feature requests.
When I use the below command
abigen --pkg erc20 --sol gole.sol --out erc20.go to generate a go file from solidity file. However, I noticed it has a missing type abi.ConvertType from one of the goethereum libs. It leads to error message , undefined: abi.ConvertType.

System information

Geth version: 1.15
OS & Version: Linux/Ubuntu 20

It's a breaking change in the API - @MariusVanDerWijden is working on it

[MariusVanDerWijden]

We recently changed the abi generator in order to remove some code. You need to update your geth version to v.1.23 if you want to use the bindings generated by v.1.23. Please let me know if it still fails if you update your version to v.1.23

@MariusVanDerWijden Please I upgraded and I still have geth version 1.9.23-unstable. Does Beth version 1.23 exist? If yes, how can I get it?

[MariusVanDerWijden]

No It doesn't exist yet, sorry. The change we made to abigen is here: #21091
Sorry for the confusion. You either need to recreate your bindings with an older version of abigen or wait until the next release.

@MariusVanDerWijden Okay... Please how do I set to a version and which version would pass without this error message? Sorry for the newbie question

[MariusVanDerWijden]

Easiest is to download the abigen binary from here: https://geth.ethereum.org/downloads/ make sure to select geth & tools 1.9.22 .
Then you can recreate the bindings just as you did previously but this time with ./path/to/abigen ....
And then it should work. All versions < current master and v1.23-unstable should work. Only they have this change

Encountered this error today. I'm using abigen 1.10.6-unstable-f05419f0-20210715 and it still produced a go file that contained the *abi.ConvertType syntax.
