我正在从源代码构建以太坊（因为我需要将源代码提供给调试器，以跟踪其工作原理）并且我在构建期间出错：
[niko@localhost sources]$ go run github.com/ethereum/go-ethereum/cmd/geth/main.go ---verbosity 5 --ipcdisable --port 40401 --rpc --rpcport 9101 --pprof --datadir=/home/niko/saved-niko-home/myeth/ --networkid=15 console

所有未定义的符号都包含在这些文件中：
[niko@localhost sources]$ ls -l github.com/ethereum/go-ethereum/cmd/geth/config.go github.com/ethereum/go-ethereum/cmd/geth/chaincmd.go github.com/ethereum/go-ethereum/cmd/geth/monitorcmd.go github.com/ethereum/go-ethereum/cmd/geth/accountcmd.go

[niko@localhost sources]$
但是，如果我将这些文件添加到命令行，我将收到另一个错误（符号重复），我在另一个问题中提交了这个错误：can not use function as type in Go
所以，不知何故，使用自动构建过程，以太坊被编译为包含这些变量（configFileFlag，initCommand等），但是当我尝试手动执行时，我缺少一些东西。但是哪些东西？
