Currently we are integrating clang-tidy into our project and we found that it has troubles when we introduce interfaces to classes (in multiple files). Consider following code //driver_interface.hpp class IDriver { public: virtual void doOperation() = 0; }; //specific_driver.hpp #include "driver_interface.hpp" class SpecificDriver : public IDriver { public: void doOperation() […]
I am building this with ipopt 3.11.9-2.2build2 on Ubuntu 20.04.6, with GCC 9.4.0: #include #include using namespace Ipopt; /** * @brief Trivial quadratic problem for testing. */ class Dummy_NLP : public TNLP { public: Dummy_NLP() { } virtual ~Dummy_NLP() = default; bool get_nlp_info(Index &number_of_variables, Index &number_of_constraints, Index &number_of_nonzero_jacobian_entries, Index &number_of_nonzero_hessian_entries, […]
I'm not a network programmer, my design choices are just based on my Google searches. My Scenario My clients could receive some events reported by other clients from the server consecutively, and asynchronously there are other requests from the client to the server.

Considering I have a struct iphdr *ip_hdr; and want to print saddr/daddr using printf. Using two separate printf calls: printf("received packet from %s\n", inet_ntoa(*(struct in_addr*)&ip_hdr->saddr)); printf("received packet to %s\n", inet_ntoa(*(struct in_addr*)&ip_hdr->daddr)); correctly prints the source/destination addr. Why does printf("received packet from %s to %s\n", inet_ntoa(*(struct in_addr*)&ip_hdr->saddr), inet_ntoa(*(struct in_addr*)&ip_hdr->daddr)); print use […]
Snippet, also on godbolt #include #include template auto select_tuple(Tuple&& tuple, std::index_sequence) { return std::tuple( std::get(std::forward(tuple))...); } int main() { std::tuple t{1, 'x', 2.0}; auto t2 = select_tuple(t, std::index_sequence{}); } As you can see in the godbolt link, the compiler throws an error: /opt/compiler-explorer/gcc-snapshot/lib/gcc/x86_64-linux-gnu/15.0.0/../../../../include/c++/15.0.0/bits/utility.h:135:5: error: implicit instantiation of undefined template 'std::tuple_element' […]
As written in the title, how? I thought that DXGI_SWAP_CHAIN_FLAG_ALLOW_MODE_SWITCH in DXGI_SWAP_CHAIN_DESC::flags was responsible about this, but even when I set DXGI_SWAP_CHAIN_DESC::flags to 0, the switching doesn't disable.
