Description

Enviroment : gcc-7 7.3.0-27ubuntu1~18.04

Additional Libraries: Protocol Buffers.

The current amcl crypto that i am using as backend, redefine FP_ZERO, that it is by default defined in math.h in libgcc that it is included in protocol buffers, since i am rewriting dta and rps with protobuf3 using amcl.

This leads to users to be not able to compile. The solution is quite trivial, just put

#ifndef FP_ZERO

#define FP_ZERO 0

#endif

This will solve the issue.

Best Regards,

Giorgio
