Still not solved. After analysis, it may be that X11 is not fully installed, So enter:Sudo apt-Cache x11-dev

[Email protected]: ~ /Codes/$ sudo apt-cache search x11-dev
Libgl1-mesa-swx11-dev-a free implementation of the OpenGL API -- Development files

Libgtkglextmm-x11-dev-C ++ wrapper for the OpenGL extension to GTK (Development files)
Libx11-dev-X11 client-side Library (Development headers)

Install the above components separately. The command is as follows:
Sudo apt-Get install libx11-dev
Sudo apt-Get install libgtkglextmm-x11-dev
Sudo apt-Get install libghc6-x11-dev
Sudo apt-Get install libgl1-mesa-swx11-dev
