编译遇到的问题及解决方法
1、gorocksdb包问题
通过go get 获取最新的gorocsdb，遇到
file: 'file:///home/zhiguo/go/src/github.com/tecbot/gorocksdb/db.go'
severity: 'Error'
message: '# github.com/tecbot/gorocksdb
could not determine kind of name for C.rocksdb_cache_get_pinned_usage
could not determine kind of name for C.rocksdb_cache_get_usage
'
at: '1,1'
source: ''
查看tecbot/gorocksdb说明文档发现，需要在系统上先build RocksDB v5.5+.
根据facebook/rocksdb安装文档，参考安装rocksdb博客，发现仍未解决问题。
最终临时解决方法：比较最新的tecbot/gorocksdb(有49个文件)和fabric/vendor/github/tecbot/gorocksdb(有29个文件)，尝试在gopath/src/github.com目录下，删除最新的tecbot/gorocksdb，然后复制粘贴fabric/vendor/github目录下tecbot/gorocksdb`，
最终项目可进行编译。
在编译的过程中又遇到如下错误：

发现某些类型重复
临时解决方法：将fabric/vendor/tecbot/gorocksdb删除，项目可编译
2、可执行程序
在geth-pbft目录下，终端运行go install ./cmd/geth只生成geth可执行文件，而通过go install ./...编译所有的geth-pbft文件，生成七个可执行文件：abigen、bootnode、evm、faucet、geth、puppeth、rlpdump，都位于gopath/bin目录下，其中会用到的有geth和puppeth
但是，系统存在之前安装的geth和puppeth，位于usr/bin目录下，将其通过sudo mv XXX /home/ethtest/gethexe移动到其他目录下。如果不进行此操作，在终端运行的geth和puppeth都是之前安装的版本，并非本次编译生成的可执行文件。
若要测试编译生成的geth和puppeth，可在gopath/bin目录下将可执行文件重命名，比如geth2、puppeth2，然后运行。
