I don't understand who to avoid that error.
Could you help me please ?

a) check if you have "using namespace std;" somewhere in your code, or
b) try and replace the calls to the map(...) function, like "touch_last_x = map(p.y, TOUCH_MAP_X1, TOUCH_MAP_X2, 0, gfx->width())" with "::map(...)", i.e. "touch_last_x = ::map(p.y, TOUCH_MAP_X1, TOUCH_MAP_X2, 0, gfx->width())".
