I've built the game successfully from github, but I don't know how to run it. I've tried with "./ygopro" and I get this:

Irrlicht Engine version 1.8.1

After this is written, a window appears for short time and then disappears.

I can run the official release that I have installed on Windows with Wine successfully.

Does the difference in Irrlicht version cause the game to crash or should I run the game some different way?

You should try to match the library version.

@adriano

If you know how to do that, please tell me. Where in source code can I change what version of Irrlicht is ygopro compiled with?

you should compile with the ubuntu provided irrlicht.
ubuntu has already all the necessary libraries already in the repository.

the workflow on ubuntu is as follows:

git clone "the fluorohydride ygopro repository"
download premake4
premake4 gmake
cd build
in the ygopro.make change "-l liblua" into "-l liblua5.2"
make

copy the generated executable into the ygopro percy folder
./ygopro

Great, I did it. I had to copy the executable in the right directory 😛 Is it normal that I only get offline mode (LAN, Puzzle, ... and no Multiplayer)?

yes.

The open source version has no official support for multiplayer and AI mode.
To play online with the open sourced ygopro:
go to LAN mode
enter this ip: "173.224.211.157"
enter this port: "21001"
in the username field put your username followed by $ and your password.

Here are the full instructions to play multiplayer with the open source version:

Username and password to what exactly? This site?
Also, where do I get the online version then?
Thanks for all your help 🙂

no, just enter with a random username$password.
if you pick an unused username the account is created automatically.

the account on the website is not related to the one you create in the game.

The online version is closed source and can be downloaded from this website.
