conan-center-index VS Vcpkg

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/

5.4.5 can be compromised

vcpkg may expire assets after 1.5 years, so achieve long-term reproducibility you will need to cache your dependencies.... Somewhere. Not sure what the expected solution is.

There were various approaches recommended depending on our language and ecosystem. My classmates who developed using Node.js were recommended npm, and PyPI or poetry for Python. Since my program is written in C++, I was recommended to look into one of vcpkg or conan, but I ultimately did not use either package manager.

Which dependencies are not in vcpkg? We can ask them to add it. It’s pretty easy just open an issue there https://github.com/microsoft/vcpkg/issues .

The hyperscan update to vcpkg seems to have happened from 5.4.0 to 5.4.2 in this commit on Apr 20.

Dear Fictrac team, I am hoping to install Fictrac in our windows 11 x64 laptop (Visual Studio 2019, cMake 3.26.4). I followed the installation guideline on github page fictrac and used the latest vcpkg

This works fine if one wants to do stuff like clang main.cpp -lvulkan, or even find_package(Vulkan REQUIRED) in CMake, but it doesn't define VULKAN_SDK, and therefore doesn't work with vcpkg's Vulkan support, for instance. A fair bit of Vulkan development, tutorials, etc. assume that the entire SDK is installed, as-is.
