The path is ${HOME}/d_apps/steering/steering/game_object.d

Compile command is

dmd map/map.d main_visual.d -ofmain_visual -H -gc -unittest 
-L-lDgame -L-lDerelictUtil -L-lDerelictGL3 -L-lDerelictSDL2 
-L-ldl -I/home/real/d_apps/dgame/source 
-I/home/real/d_apps/derelict_util/source 
-I/home/real/d_apps/derelict_gl3/source 
-I/home/real/d_apps/derelict_sdl2/source 
-I/home/real/d_apps/steering

Compiler message is same
