Environment information
- OpenFOAM version : v2012
- Operating system : macOS 11.4 (arm)

Possible fixes
Line 528 in searchableSphere.C causes the error:
std::array<uint8_t, 3> idx{0, 1, 2};A quick fix is to add the array header at the top of the file:
#include "searchableSphere.H"
#include "addToRunTimeSelectionTable.H"
#include <array>
