void CityXMLManager::print_patch_to_xml (
patch_type _type,
vector <patch_type> & _neighbours_types,
vector <pair<Vector3, float > > & _obstacles)
您好， 我想问一下上面的行是否在语法方面被接受了？这行代码以前在Window和Visual Studio 2008编译中运行良好。然后，当相同的代码进入mac os x环境时，错误就会出现。有人将这些代码传递给我，我不明白这一行中发生了什么。
抱怨的错误是：
Use of undeclared identifier 'patch_type'
Variable has incomplete type 'void'
'_neighbours_types' was not declared in this scope
'_patch_types' was not declared in this scope
Reference to 'vector' is ambiguous
提前致谢！
