我正在尝试使用 boost::spirit::qi 解析以下字符串。
连接时钟 sda 1.020::1.030 0.200::0.00
CONNECT da doai 0.100::0.050 0.040::0.300
然后通过回调发送解析出的token。但是出现以下错误。 只有在尝试解析长序列时才会出现编译问题。如果语法序列更短，编译问题就会消失。
例如，如果我使用下面的语法解析以下内容，则没有编译错误。
连接时钟 0.200::0.00
连接 da 0.040::0.300
auto connect_parser = qi::copy(qi::lit("CONNECT") >> qi::space >> pin_parser[boost::phoenix::bind(callback, "PIN1", qi::_1)] >> qi::space
>> val_parser >> qi::space
);
