When i run this command :(make c2play-x11) i get the following message:

==== Building c2play-x11 (debug) ====

Thank you in advance.

Ensure you have the development headers (libass-dev) installed as shown in the README.
https://github.com/OtherCrashOverride/c2play/blob/beta1/README

Install dependencies:
sudo apt install libasound2-dev libavformat-dev libass-dev

Now the previous issue is ok. (In master branch there wasn't a readme file.Thank you for point out)

Now it prints the following:

In file included from ../../src/UI/Compositor.h:27:0,
from ../../src/UI/Compositor.cpp:17:
../../src/UI/Egl.h:22:21: fatal error: EGL/egl.h: No such file or directory
compilation terminated.

Thank you!

Nevermind,I run this command:
sudo apt-get install libglfw3-dev libgles2-mesa-dev

and now is ok.

Thank you very much for your support.
