Dinesh - have you read https://github.com/PX4/Firmware/issues/9863 which seems to discuss the same compile error that you are observing error: expected initializer before '_PARAMS' extern double atan PARAMS((double));?

Thanx Geoff,
I tried those methods given in the link. in short the link tells to update GCC. I did that. But i got new a error which is given below. If u come across any solution kindly forward me.

You listed your product as the MATLAB and Simulink Student Suite. I don't believe that product allows compilation.
Walter Roberson
Walter Roberson 2018-8-21
You will need to reconfigure so that warnings are not treated as errors. The code at that location has
case 'd': sign = true;
/* FALLTHROUGH */
case 'u': base = 10; break;
which is valid C, even if it could be better written.

Something in your compilation chain is compiling with
-Werror=implicit-fallthrough=
You need to either remove that or else add
-Wno-error=implicit-fallthrough=
(I do not know what would happen if both appear on the same command line.)
