Boost BiMap解析模板错误

Question

当我添加#include<boost/bimap.hpp>时，我得到了解析模板错误，我想从它的值中找到映射键，因此我想使用Boost的Bimap，但得到了下面的错误。

/usr/include/boost/bimap/relation/structured_pair.hpp: In function ‘bool boost::bimaps::relation::operator<(const boost::bimaps::relation::structured_pair<FirstType, SecondType, Info, Layout1>&, const boost::bimaps::relation::structured_pair<FirstType, SecondType, Info, Layout2>&)’:
/usr/include/boost/bimap/relation/structured_pair.hpp:375:19: error: parse error in template argument list

使用GCC 4.8.5：

• boost 1.64 https://wandbox.org/permlink/kg4tkbEIdHMv4mII
• boost 1.60 https://wandbox.org/permlink/1lA2L194rNfZrFsd
• boost 1.54 https://wandbox.org/permlink/7RUl49NAy0q9D2u3
• boost 1.49 https://wandbox.org/permlink/kpILpo63riVQGVyP

所以总而言之，看起来你还做错了什么。还包括哪些内容？如果可能，请检查预处理过的源代码。
