CMake can't find X11

Question

I'm trying to compile Minetest 0.4.10 on Ubuntu 12.04.3 LTS with CMake, but I get this error:

andrew@rasts-tv:~$ cmake \Minetest-0.4.10
-- *** Will build version 0.4.10 ***
-- IRRLICHT_SOURCE_DIR = 
-- IRRLICHT_INCLUDE_DIR = IRRLICHT_INCLUDE_DIR-NOTFOUND
-- IRRLICHT_LIBRARY = IRRLICHT_LIBRARY-NOTFOUND
-- Could NOT find IRRLICHT (missing:  IRRLICHT_LIBRARY IRRLICHT_INCLUDE_DIR) 
-- CURL_INCLUDE_DIR = CURL_INCLUDE_DIR-NOTFOUND
-- CURL_LIBRARY = CURL_LIBRARY-NOTFOUND
-- CURL_DLL = 
-- GetText disabled
CMake Error at /usr/share/cmake-2.8/Modules/FindX11.cmake:411 (MESSAGE):
  Could not find X11
Call Stack (most recent call first):
  src/CMakeLists.txt:147 (find_package)


-- Configuring incomplete, errors occurred!

I installed LXDE (Lightweight X11 Desktop Environment), but it still shows the same error. What should I do?

This is the error message I got after installing the x11 header files:

andrew@rasts-tv:~$ cmake \Minetest-0.4.10

Answer 1

LXDE and X11 are not quite the same thing. You probably need the X11 header files. Try installing libx11-dev:

sudo apt-get install libx11-dev

Answer 2

try running the command

sudo apt install xorg-dev
