It looks like that function call takes a double as a parameter, which is a type of floating point number. I’m guessing that’s why the compiler is complaining that the ‘+nofp’ feature can’t be used with that function.

Hi Vijay,

Thank you for this patch.
This patch as such looks ok to me but I am getting a build the following failure when openssl library is being built.
