ola VS cpr

You won’t be able to use both universes usb connection. But I use my own mkII via Ola running on a virtual machine and a unicast artnet connection. Never had an issue with this setup and it allows to use both universes. This could help solving you crash issue…

You could in fact une an open DMX. You need to setup an ola server (https://www.openlighting.org/ola/ ) which would read the artnet input and convert it to the open DMX.

https://www.openlighting.org/ola/ is a nice library which can talk to a lot of different things (USB / various Ethernet protocols). It is pretty easy to include into a python script as well. Then you could do the UI stuff in python and rely on OLA for the DMX output.

This one might fit the bill https://github.com/libcpr/cpr

There is also the cpr package which should offer a more c++ focussed interface for curl.

So I'm very new to C++ and I'm trying to write a C++ version of a tool that I put together in Python. I'm trying to use libcpr for all my HTTP needs. I've spent the day trying to get it set up and working, but I'm getting a bunch of linking errors when I try to run. I really don't know if I did the building of it correctly, I'm trying to use Visual Studio Community 2022 and the Usage section of their docs talks about CMake and a couple package manager methods.

I think vcpkg manifests have solved a really key portion of the "please give me these libraries" problem. Couple lines in a json file, pass CMake to your vcpkg toolchain script path and triplet, and you're pretty much done with dependencies. I actually used it for a project with libcpr/cpr and a couple other popular libraries, and I was shocked at how painless it was to get up and running with some web request stuff.

Libraries like nlohmann's json, cpr, fmt are prime examples of what I'm seeking. Any suggestions?

Basically specifying the language and the repo, and it does work when the request is made from postman or from the browser. However, when using https://github.com/libcpr/cpr, I'm getting the following response:
