Hi @Joao_Abrantes, the Anysphere C/C++ extension relies on Clangd for the language server, which needs to be configured via a compile_commands.json (the build tool, such as CMake, can generate this file). Please see Intellisense disabled in new C++ extension and the Clangd Getting Started Guide for more on configuring Clangd.
