I'm using Cyclone IV DE2-115 board, I have tried connecting the CLOCK_50 input to the clocks pin according to this manual ftp://ftp.altera.com/up/pub/altera_material/13.0/boards/de2-115/de2_115_user_manual.pdf. I tried PIN_Y2 (CLOCK_50) as well as PIN_AE23 (SMA_CLKOUT) both this warning still persists. Any help would be greatly appreciated!
module uart(
input wire CLOCK_50, // map to onboard clock (50 MHz)
input wire i_Rx_Channel, // Rx channel, map to general purpose pin
input wire i_Tx_DV, // signals TX to read a byte to send
input wire i_Tx_Byte, // byte to be sent by Tx
output wire o_Tx_Channel, // Tx channel, mapped to GPIO 1
output wire o_Rx_Ready,
output wire received_Rx_byte); // map to onboard LEDs for testing
parameter c_CLOCK_PERIOD_NS = 100;
parameter c_CLKS_PER_BIT = 434;
parameter c_BIT_PERIOD = 8600;
uart_rx# (
.CLKS_PER_BIT (c_CLKS_PER_BIT)
) receiver(
.i_Clock (CLOCK_50),
.i_Rx_Serial (i_Rx_Channel),
.o_Rx_DV (o_Rx_Ready),
.o_Rx_Byte (received_Rx_byte)
);
endmodule

No clocks defined means you didn't create a .sdc file for timing analysis. You need to constrain the design.

But it shouldnt affect whether my code works correct? Thanks!
