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", "bin,abi,userdoc,devdoc", "--optimize", // code optimizer switched on } if s.Major > 0 || s.Minor > 4 || s.Patch > 6 { p[1] += ",metadata" } return p }
解决
