Unable to build the hello world

[VoreckLukas]

So i dont know which repo this issue belongs to so I'll put it here. I tried to get this set up on nixos together with devkitnix to install the devkit toolchain. But when i try to run cargo 3ds build on the initial hello world i get the below compiler error

❯ cargo 3ds build

[Meziu]

You're trying to compile mio and socket2, which are io/net related libraries that officially support UNIX-like targets (mainly Linux and MacOS). The Nintendo 3DS does not follow such standards and is not supported by those libraries (but work can be done to support it, at least partially and out-of-tree).

You can have a look at our network-sockets example, which uses only std::net sockets (which are almost fully supported).

Also, an hello-world that needs sockets doesn't look like a proper hello-world program, are you sure you are compiling the correct example?

[VoreckLukas]

I just did a cargo 3ds new and a cargo 3ds build idk why it's pulling in networking

[VoreckLukas]

my bad. I realized I pulled in an mqtt library (not using it yet, just pulling it in) and that seems to have borked it (pulled it in as preparation for what i want to do
