Upload to the board failed after LCD enabled

Hi Folks,

I recently brought BigTreeTech SKR V1.3 and uncommented REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER and clicked upload button but faced
an error that say

Marlin\src\lcd\ultralcd.cpp:767:9: error: 'touch_buttons' was not declared in this scope
if (touch_buttons) {
^~~~~~~~~~~~~
Marlin\src\lcd\ultralcd.cpp:767:9: note: suggested alternative: 'buttons'
if (touch_buttons) {

^~~~~~~~~~~~~
buttons
Marlin\src\lcd\ultralcd.cpp:805:5: error: 'else' without a previous 'if'
else wait_for_unclick = false;
^~~~
*** [.pio\build\LPC1768\src\src\lcd\ultralcd.cpp.o] Error 1

I am not sure what above mean but can anyone shed light to why I am recieving these errors?

Its a bug in latest marlin... reported here [github.com]

Someone has presumed that touch is active in this part of the code without checking it has been enabled

A hack to get it to work is

edit Marlin\src\lcd\ultralcd.cpp:

at line 767 you will find

if (touch_buttons) {

insert the following above that line

#if ENABLED(TOUCH_BUTTONS)

so it becomes

#if ENABLED(TOUCH_BUTTONS)
     if (touch_buttons) {

at line 793 you will find

else {

add this line after it

#endif

at line 806 you will find the line

}

change it to

#if ENABLED(TOUCH_BUTTONS)
    }
  #endif

Sorry I did not followed your suggestion correctly so now its works, the upload passed but nothing show up on the display.

The board is connect to the computer with REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER connected. Any suggestion to why it not showing up?

An official fix has been posted. Grab the new ultralcd.cpp from [github.com]

Thank you for the update DUST, the display controller is not showing anything, what could that be? I looked in U8glib-HAL and don't see REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER supported?
