Hi I am new to arduino and have very little coding experience. I am trying to set up my firmware for my 3D printer and I keep getting this error message:
sketch\Marlin_main.cpp:2802:36: warning: invalid suffix on literal; C++11 requires a space between literal and identifier [-Wliteral-suffix]



sketch\Marlin_main.cpp: In function 'void set_bed_level_equation_lsq(double*)':

sketch\Marlin_main.cpp:978:36: warning: deprecated conversion from string constant to 'char*' [-Wwrite-strings]



In file included from sketch\ultralcd.cpp:44:0:
