This Nix Friday I will be in the stream as well and we will talk about the C/C++ infrastructure in nixpkgs. We won’t talk too much about the language itself, but how the compilers/linkers are integrated into stdenv and how the build system abstraction works. If you happen to package C/C++ applications or libraries, this should give you a good overview. If you have any question you want to answered, please post them here: Nix Friday: C/C++ questions for next stream
