Error compiling SPECS.cpp file

[sajidmahmud]

I followed the instructions from the Readme file and ran the following command:

g++ -o SPECS SPECS.cpp
However, I am getting the following error,

SPECS.cpp: In function ‘long double u3b(long double*, long double ()[3000], long double ()[3000], int, int, long double, long double ()[4], long double, int)’:
SPECS.cpp:1932:1: warning: control reaches end of non-void function [-Wreturn-type]
1932 | }
| ^

What could be the reason for this? I am trying to use it on a 64 bit Ubuntu machine.
