我想知道获取error: invalid value '6' in '-O6'的原因和一些解决方案来超越此错误。当我尝试编译c ++比特币的区块链解析器项目时，会出现此问题。实际上这个项目的作者似乎只是在Ubuntu OS中编写了它，尽管我试图在我的OS X中编译这些代码。
以下是make命令的输出：
c++ -- cb/allBalances.cpp
c++ -- cb/allAddresses.cpp
c++ -- callback.cpp
c++ -- cb/dumpTX.cpp
c++ -- cb/closure.cpp
c++ -- cb/help.cpp
c++ -- option.cpp
c++ -- opcodes.cpp
