1. abigen 参考文档(Native DApps: Go bindings to Ethereum contracts)

abigen --sol token.sol --pkg token --lang go --out token.go
Trying to bind solidity with abigen command,results in this error:

Failed to build Solidity contract: solc: exit status 1
unrecognised option ‘--add-std‘

func (s *Solidity) makeArgs() []string {
    p := []string{
        "--combined-json","bin,abi,userdoc,devdoc","--add-std",// include standard lib contracts
        "--optimize",// code optimizer switched on
    }
    if s.Major > 0 || s.Minor > 4 || s.Patch > 6 {
        p[1] += ",metadata"
    }
    return p
}

更新到新版的ethereum发现

func (s *Solidity) makeArgs() []string {
    p := []string{
        "--combined-json","--optimize",metadata"
    }
    return p
}

解决
