## +23 ## Shared Libraries in Windows, in Linux, and yes - in C++ ## OFEK SHILON ## Terminology ## • Shared Library: - Shared Object, Dynamic Object, Dynamic Shared Object (DSO), Dynamic Load Library Library (DLL), Dynamic Shared Library • Binary: • Executable / Shared Library, Component, Module • Symbol: • Function / Global variable • "Linux": • Unix-like systems • Mostly MacOS too (1 important address (6.8.2), they compare equal.” • Actual calls are made to a PLT entry. • Different among libraries!  ## C++ Implication

## Generic Graph Libraries in C++20 ## ANDREW LUMSDAINE, PHIL RATZLOFF 20 21 October 24-29 ## About Us  ## • Andrew areas related to high-performance computing, including systems, programming languages, software libraries, and large-scale graph analytics. Open-source software projects resulting from his work include practical (concrete) problems – theory reuse • Goes hand-in-glove with goals of generic software libraries  ![Image](/upl

## +24 ## Reflection Based Libraries to Look Forward To ## SAKSHAM SHARMA ## Reflection based libraries to look forward to ## Saksham Sharma CppCon 2024 ## Why me Director, Quant Research Tech at languages (Go, Python, Java) • Reflection in C++ as per P2996 ☐ Syntax and examples • Reflection libraries! Python bindings ABI hashing (boost::abi_hash?) A duck-typed std::any (boost::virtual_any?) Reflection libraries! • Reflection is a really powerful language feature ☐ With great power comes great responsibility • Easier to write general-purpose / boilerplate-reducing libraries • Solve multiple

It also integrates the following additional but essential limited only by the available memory. There is thus no real limitation to the number of components, component pins, connections, or sheets.
