Ubuntu/Linux Port?

[omerXfaruq]

Hello,

This is a awesome application, thank you very much.

Does this app create a vpn on discord server? Or does it connect users to each other using the discord server as an initial bridge? Is there any documentation available?

Do you plan to port this app to ubuntu/linux? It seems it is only available for windows.
Can we compile on ubuntu and make it work?
It seems it is designed for windows.
Can I make it work from the terminal in ubuntu, what do you think?

It uses the Discord Game API for connectivity, which uses the Discord Servers.
See https://discord.com/developers/docs/game-sdk/lobbies

Regarding support on Linux. LPVPN is written with portability in mind, but the only thing we currently support is Windows (since the majority of players use Windows).

To support Linux, one would write a TUN implementation of this interface https://github.com/gyf304/lpvpn/blob/main/src/adapter.h

I may do this at some point in the future if I have weekend cycles available, but not at the current moment.
Feel free to try implementing it and report back!

I wonder if it could be extended to Android as well.
There are some games/emulators you could use it with.
Best examples that comes to mind are PPSSPP and Flycast.

Well I am able to run it with wine. But when I click either host or join, I get this error.

would be awesome to have on linux x86_64 and armhf aarm64

so this suggests the C++ code is mostly cross platform.
some work and this will build, mainly removing static libaries for windows, replace them with cmake checks to determine platform.
im not a programmer, so i cant help develop this.

#13

git clone https://github.com/gyf304/lpvpn/
cd lpvpn
mkdir build
cd build
cmake ..
make

not sure if make is correct here. make is usually good for C programming where g++ is used in C++

Did someone found a way to to run it on Linux?
