This is because of the update to the compiler.
I have fixed this issue by changing the following in odom.h:

static const double wheel_radius_ = 0.1325;
static const double wheel_tread_  = 0.248;

to

static constexpr double wheel_radius_ = 0.1325;
static constexpr double wheel_tread_  = 0.248;

Thank you for the comment. It will be fixed in melodic-devel.
