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?
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 […]
Chrome fails to read message fron Native host if the message length is multiple of 256
03/07/2025 by Nikos Papachatzakis
I'm building a chrome extension what utilizes a native messaging host for getting information about the DOM and transfer them to another app. During my testing i managed to send a message to the chrome extension that was exactly 266 bytes long (270 accounting the 4 bytes for length). After […]
FFMpeg D3D11 decoded image to OpenCV UMat
03/07/2025 by Spuriga
I would like to copy FFMpeg decoded image data to an UMat WITHOUT copiing it to the cpu ram. Is there any way to do it? What if there are two or more GPU card in the PC? I have this code for av_image_copy_to_buffer, works fine, but if I change […]
QQmlContext::setContextProperty alternative
03/07/2025 by kzsnyk
Back to Qt after some time, i can see a lot of changes from Qt5 to Qt6, and especially regarding the way C++ objects may be exposed to QML. From https://doc.qt.io/qt-6/qtqml-cppintegration-contextproperties.html void QQmlContext::setContextProperty(const QString &name, QObject *value) does not seem relevant anymore and best avoided from modularity reasons. Now every […]
Passing info between different branches of a class hierarchy in C++?
03/07/2025 by Rares Dima
So, I have a class hierarchy that looks like this: It is an embedded project, so the entire code will be run over and over. I have several algorithm classes, that compute some result given some inputs. The results are written to some structs (that contain the necessary members). class […]
How to convert a std::optional to a std::expected?
03/07/2025 by user2138149
I'm trying to convert a std::optional into a std::expected using a lambda function. The code I have written does not compile. The compiler complains that the monadic functions of std::optional must return another std::optional. Here's my example code, which can be found on Godbolt. godbolt link #include #include #include std::optional […]
