std::bad_expected_access is a template class that is thrown. I have code that only cares that any instantiation of it is thrown, not which instantiation. Is there a way to catch (or some other mechanism) all instantiations of a template that are thrown?
I am receiving a segmentation fault when calling the solve() method from the class mySolver, but I only receive this error when it is called from another class for which it is a member. I believe that solve() has been implemented correctly as I have called it before (not stored […]
I want the picture to be fully displayed in the window. I render my own image by inheriting QQuickItem and using OPenGL. As in the QT case https://doc.qt.io/qt-6.5/qtquick-scenegraph-openglunderqml-example.html. I suspect this may have something to do with the vertex coordinates, which cause the texture to be obscured by other elements […]
I am trying to render a 3D cude on the window and observe the perspective projection. In the vertex shader when I dont multiply the projection matrix, the cube gets rendered (but you cant observe the perspective projection). When I multiply the perspective projection matrix the cube seems to be […]
My problem is that I do not know how to properly change the fluent-bit configuration in my c++ application during program execution. I use two plugins: tail and lib. There is a need to change the readable files for the tail plugin at any time. The configuration yaml file looks […]
I created two identical programs (one in Rust and one in C++). They are single threaded, and there are no heap allocations. The rust version (cargo run --release) runs in 12 sec. The C++ version (compiled with MSVC /O2 Release or gcc) runs in 17 sec. Profile guided optimization didn't […]
I am responsible for securing an old Windows C++ project. It uses the MFC ODBC CDatabase class to interface with SQL-Server. All DB query and insert operations are done using parameterized stored-procedures, so it seems like good practice. But almost all the DB C++ code prepares statements in this form: […]
want to add Firebase to an Axmol Game engine ios project (https://github.com/axmolengine/axmol) . I used to add the xcframeworks with CMake, but the firebase-ios-sdk does not have the xcframeworks. When I try to add firebase-ios-sdk with the Swift Package Manager, Xcode blocks with the message 'preparing to validate' with no […]
