Same for me in Ubuntu 18.04 with all the X11 packages installed.

Any solution? :(

[WildBoarGonnaGo]

Same problem

[Gtalavero]

Same problem
Do you fix it? If you do, can you tell how?

[amalliar]

@Gtalavero I've added missing function declarations and headers here: #12
Note: if you want to be able to compile mlx-test, you need to temporarily comment out line 134 in mlx_int.h:
int (*(mlx_int_param_event[37]))();
