conan-center-index VS VulkanExamples

Conan is a package manager for C/C++. See: https://conan.io/.

The way it works is that you can provide "recipes", which are Python scripts, that automate the process of collecting source code (usually from a remote Git repository, or a remote source tarball), patching it, making its dependencies and transitive dependencies available, building for specific platform and architecture (via any number of build systems), then packaging up and serving binaries. There's a lot of complexity involved.

Here are the two recipes I mentioned:

libcurl: https://github.com/conan-io/conan-center-index/blob/master/r...

OpenSSL v3: https://github.com/conan-io/conan-center-index/blob/master/r...

Now, for the sake of this thread I want to highlight three things here:

- Conan recipes are usually made by people unaffiliated with the libraries they're packaging;

- The recipes are fully Turing-complete, do a lot of work, have their own bugs - therefore they should really be treated as software comonents themselves, for the purpose of OSS clearing/supply chain verification, except as far as I know, nobody does it;

- The recipes can, and do, patch source code and build scripts. There's supporting infrastruture for this built into Conan, and of course one can also do it by brute-force search and replace. See e.g. ZLib recipe that does it both at the same time:

https://github.com/conan-io/conan-center-index/blob/7b0ac710... -- `_patch_sources` does both direct search-and-replace in source files, and applies the patches from https://github.com/conan-io/conan-center-index/tree/master/r....

Now, good luck keeping track of what's going on there.

Just checkout ConanCenter https://conan.io/center it's free.

https://github.com/conan-io/conan-center-index there's 200+ PR that need reviewing :) we add community reviewers fairly often

As for ffmpeg it was last updated 10 days ago https://github.com/conan-io/conan-center-index/commits/master/recipes/ffmpeg/all :)

This is a more complicated recipe https://github.com/conan-io/conan-center-index/blob/master/recipes/pcapplusplus/all/conanfile.py

You can use the Conan package manager with prebuilt binaries/libraries

https://conan.io/center

It's available in Conan too https://github.com/conan-io/conan-center-index/tree/master/recipes/crowcpp-crow though it's not well maintained so no promises if it's working

You need something like https://conan.io/center/ to install the dependencies. You're lucky because it works well with CMake.

This post on github contains a list of packages supported by conan 2.0, its also kept up to date https://github.com/conan-io/conan-center-index/discussions/16196

Use a package manager: https://vcpkg.link/ https://conan.io/center/

cmake_minimum_required(VERSION 3.11) project(my_project LANGUAGES CXX VERSION 1.0 ) include(FetchContent) FetchContent_Declare( glfw GIT_REPOSITORY "https://github.com/glfw/glfw" GIT_TAG dd8a678a66f1967372e5a5e3deac41ebf65ee127 ) message("Fetching glfw...")

The second sample comes from NVIDIA. It shows a transcoded version of the API sample, High Dynamic Range, and illustrated the usage of the C++ binding of Vulkan provided by Vulkan.hpp. Sample - https://github.com/KhronosGroup/Vulkan-Samples/tree/master/samples/api/hpp_hdr Vulkan.hpp - https://github.com/KhronosGroup/Vulkan-Hpp

or https://github.com/KhronosGroup/Vulkan-Hpp which help quite a bit. Or https://github.com/VcDevel/std-simd.

If you want GUIs, same, you have at least (but not only) Qt or WxWidgets.

Want to interface scripting? Pybind11, Boost.Python, WrenBind17 for Wren, Sol2 for Lua... and all things that interface to C work also if you feel brave...

I really think that when it is about getting the job done... C++ goes a long way towards the task.

This is my 20 year experience of C++, almost 13 of those years professionally. Now, back to read the paper. :)

If you're not a complete beginner, the vulkan.hpp version of Sascha Willems' samples is out of date, you could contribute some updated examples. You'd get a decent overview of various Vulkan features and become familiar with both the C and C++ APIs.

I don't have a cheat sheet but I do have a repository with a bunch of examples that use the C++ api https://github.com/jherico/vulkan
