warning: ISO C++ says that these are ambiguous, even though the worst conversion for

[Ferric]

The complete warning message is : warning: ISO C++ says that these are ambiguous, even though the worst conversion for the first is better than the worst conversion for the second:
candidate 1: bool QByteRef:perator==(char) const
candidate 2: operator==(int, int) <built-in>

which refers to the following code
:

if (receivedMessage[0] == 0x0a)

if (receivedMessage[0] == 0x0a)

To copy to clipboard, switch view to plain text mode 

Is there a better way to write this code to get rid of this warning? Thanks for any help.

The message arises because the constant is an int, not a char.

if (receivedMessage[0] == '\x0a') 
if (receivedMessage[0] == char(0x0a))

if (receivedMessage[0] == '\x0a') 
if (receivedMessage[0] == char(0x0a))

To copy to clipboard, switch view to plain text mode

if(receivedMessage.at(0) == 0x0a)

if(receivedMessage.at(0) == 0x0a)

To copy to clipboard, switch view to plain text mode

All of the above seem to work, Thanks!
