Noticed a lot of people asking for this bit there isn't much help with this... so here it is....

Note:
no credit for this as I didn't make any of this.
All credit goes to the dev for the programs used. Also I wrote this up on my phone... Excuse me for the formatting. Will fix it up when I get the chance to.

Disclaimer: some phones are different and if this doesn't work, post here and we'll see if we can find a way around this. Also if your phone over heat, blows up, turns into an apple, and other issue or problem other you may encounter, none of those are my fault and you agree to the risk following or reading this tut


Requirements

• Rooted Android phone
• Decent internet to download things
• Termux installed (https://play.google.com/store/apps/details?id=com.termux)

Procedures
1. First you need to download the libs and packages required to build the client. Launch termux and enter in the following

apt update
apt install libpcap-dev
apt install libuv-dev
pkg install cmake
pkg install tsu
pkg install git

2. Download the git

git clone https://github.com/spacemeowx2/switch-lan-play.git

3. Change directory into the git folder and make a build directory

cd switch-lan-play
mkdir build
cd build

4. Build your client now

cmake ..
make

5.Your client is now built, to run it you use

tsudo ./lan-play --relay-server-addr example.com:11451

6. Profit

What does it spit out after you type

pkg search cmake

It works now, thanks!

Did you get it to work with your switch? It's running on my phone but my switch somehow can't connect to it.

Just a quick question: since this is based on linux (or a fork), is it possible to port it over to a rasp-pi 3 or something? Would be great to have this app running localy but not on any phone or pc, just a dedicated micro pc should do the trick (but thats just assumption)

I'm having a

/system/bin/sh: ./lan-play: not found

Error.

I'm on galaxy s8 rooted with magisk.

Anyone tried running this on something like UserLAnd for non rooted users? Planning to try later if nobody has.

EDIT: Seems to run into a permissions issue: "Error pcap_findalldevs: socket: Permission denied"
Running as the root user in the machine doesn't seem to fix it, so device root may be necessary.

I think I found out why I'm having the 'not found' problem. But I don't know how to fix it.

Awesome!

I will add that to the OP
Only thing i notice is, i find most phones i use doesn't come with cmake, so might be a good idea to install cmake on yours.
but then again, users can figure that out them self i guess....

No, in order for this to work, libpcap must have root access to view the network interface and modify it, hence root is required (just like on windows you may have to do a run as admin)

Do an

ls

what does that show?
you have to make sure you're in the "switch-lan-play/build" folder to run it.

Sorry for the late response. Gbatemp was having a maintenance when I sent the reply, anyway, here it is again.

you can move lan-play to data dir and then type "tsudo data/lan-play --rela........"

this works for me.

Can confirm, this one worked for me. Thanks a lot!

Nvm about the rasp, got it running localy on it (and it runs perfectly).
Just had a minor adjustment to some of the commands (Sudo instead of tsudo for instance), installed cmake and made the program within seconds.

Now to make it go autopilot if i turn off/on the raspberry pi... oh well, at least it runs
