Casting between pointer to aggregate classes with a common member and another deriving member
03/07/2025 by galinette
I have a base and derived class: struct Base { std::vector bars; std::unique_ptr fruit_ptr; } struct Derived : public Base { Foo foo; } And a template class joining an int and another object: template struct WithCounter { int counter = 0; T payload; } Is there any way I […]
Friend extern "С" function with enum return type
03/07/2025 by Xeenych Xeenych
I have to interface with a С function, but this code doesn't compile. // c_enum.h #pragma once typedef enum { val1 = 0 } c_style_enum_t; c_style_enum_t c_func(); // my_class.hpp #pragma once extern "С" { #include "c_enum.h" } class my_class { public: private: friend c_style_enum_t ::c_func(); }; Gcc prints an errror: […]
Placement new + reinterpret_cast + pointer arithmetic = UB?
03/07/2025 by Avi
Similar to the example from the std::aligned_storage page here, imagine I have the following: template class SlotArray { static_assert(!std::is_array_v); static_assert(!std::is_void_v); using StorageType = std::aligned_storage_t; public: template T* alloc(Args... args) { std::size_t index = claimIndex(); return ::new(&slots[index]) T(std::forward(args)...); } void free(T* value) { static_assert(sizeof(std::ptrdiff_t)
Using Eigen::Ref<> to pass matrix row as lvalue
03/07/2025 by Rob McDonald
I'm having trouble passing a matrix .row(i) as an lvalue reference. I think this should be solvable with Eigen::Ref, but I'm having difficulty. The large code block at the bottom of this post currently works. A profile of this code looks like this: 100% fbatch 47.1% void de_casteljau 44.8% Eigen::internal::dense_assignment_loop::run […]
Using libarchive How to find files on current directory without searching subdirectory
03/07/2025 by senthil
This example .tar file which contains the files and folders. - >Parentdir1 > Parentdir2 > file1 > file2 > directory3(It contains 10 subfolder and 5000 files) I want to find the "file2" file on tar. It recursively iterates files on "directory3" after that found "file2". I I need a solution […]
C++ nonmember binary operator with private inheritance
03/07/2025 by Topological Sort
As has been pointed out elsewhere, the community thinks C++ binary operators like == should be nonmember functions. This presents a problem for me with private inheritance. #include class Parent { public: Parent(int arg = 0) {} int member() const { return member_; } private: int member_; }; bool operator== […]
std::cout problems with specific german characters ( Ä, Ö, Ü )
03/07/2025 by Hank Gordon
I currently work on a project on a Raspberry Pi using c++. I have problems streaming german special characters to the terminal. I wrote a logger::log() function and use it inside a classmethod. If I call the logger::log() function directly in main() it works fine. If I call a certain […]
Is struct/union initialisation with pointers-to-members possible?
03/07/2025 by notgapriel
Was looking through cppreference and could not find anything similar to what I would like to use. I would like to explicitly initialise only a single member of a struct/union. For this reason I can't use the U{value1,value2} syntax (seems to be referred to as "declaration list" syntax) for structs, […]
Why does my for loop with condition i=0;i<v.size()-1 run for one iteration even when size of v is zero in C++ [duplicate]

Is there any library for obtaining depth maps from point clouds that supports using the viewport field of a pcd file for locating the camera? [closed]
03/07/2025 by user24849449
I'm trying to convert some point clouds provided as PCD files to RGBD images using open3d.t.geometry.PointCloud.project_to_rgbd_image method. The idea is to implement something like cloudcompare bubble view mode. However, the origin of the point cloud doesn't match its viewpoint, so its location is required for calculating the extrinsic matrix required […]
