The C++ standard has always forbidden containers of const elements (such as vector<const T> or set<const T>). Visual Studio 2013 and earlier accepted such containers. In the current version, such containers fail to compile. std::allocator::deallocate In Visual Studio 2013 and earlier, std::...
C++ 标准始终禁止 const 元素(如 vector<const T> 或set<const T>)的容器。 Visual Studio 2013 及更早版本接受此类容器。 在当前版本中,此类容器无法编译。 std::allocator::deallocate 在Visual Studio 2013 和早期版本中,std::allocator::deallocate(p, n) 忽略了传入用于 n 的参数。 C++ 标准始终要求 n...
std::vector<Eigen::Vector4f> v; 会出现如上问题。 看了好多文章都得不到解决,在http://blog.csdn.net/pkueecser/article/details/8535352上找到了可行的解决方法。记下来,方便以后查看 即写成:std::vector<Eigen::Vector4f, Eigen::aligned_allocator<Eigen::Vector4f>> v; 即可解决问题。 --- 作者:dou_...
Some target systems will not work with Posix malloc, realloc, free and C11 aligned_alloc. Or they might, but more allocation control is desired. The best approach is to use flatcc_builder_custom_init to provide a custom allocator and emitter object, but for simpler case or while piloting ...

例如:Vector v= Vector(1,0,0)+Vector(0,1,0)+Vector(0,0,1);创建了五个未命名的临时的Vectors对象:Vector(1,0,0),Vector(0,1,0),Vector(0,0,1),Vector(1,0,0)+Vector(0,1,0),Vector(1,0,0)+Vector(0,1,0)+Vector(1,0,0)。
