AzuraCast VS libtcod

I don't have any experience with it, but it looks like AzuraCast does what you want.

I've used AzureCast - https://www.azuracast.com/ - super simple to stand up and run - you can run multiple radio stations with it.

It’s also worth looking into RadioDj or Azuracast for solid, less complex alternatives. I might be switching back to RadioDj since it’s a tad bit easier to queue up songs.

Okay yeah so this is all wrong. I'm using this as reference for an example docker compose file.

Take a look at AzuraCast. This seems very suited to your need

Azuracast perhaps?

Azuracast. Not quite as powerful but much easier to run. Also Linux, although you can tinker to get it running under Windows. It would run well in a cloud host like Linode or Digital Ocean, which might mean you don’t need a relay service like Alon depending on how many listeners you have. You can also host it at home of course.

Libtcod itself uses SDL2. It maps tile glyphs to a texture atlas and maps Unicode codepoints to tile positions. Then it has another data structure called a console which has the background color, foreground color, and codepoint for each tile on that console. It then uses SDL_RenderGeometry to quickly render the background and colored glyphs to an SDL texture, skipping unchanged tiles as an optimization, then renders that texture to the window. The C99 source is here: renderer_sdl2.h renderer_sdl2.c, a C++ version would surely look better.

libtcod has always been a favorite of mine. Does a lot of things to zero fanfare outside the indie roguelike scene.

I've ended up recovering the old 1.3.2 to 1.5.0 builds of libtcod. You can find them on the GitHub releases page. Most of, maybe all of the other places which had these builds are down, but thankfully Jice still had copies of these builds.

FoV is a port from C -> Java of the algorithm found here

Hey man, I don't wanna piss in your cherrios if you're intentionally doing it all the hard way, but you know about tcod right? https://github.com/libtcod/libtcod/

Browsing the repo, looks like it has a full C only API, https://github.com/libtcod/libtcod/blob/master/src/libtcod/libtcod.h

libtcod support for terminals is in progress at least for ANSI true colour, and I have a minimal compatibility layer for UNIX only.
