Message <Context> the type long double _Complex is not fully supported on this platform. The type is only accepted when the compilation specifies the option to make the long double type 64-bits in size. Description On some platforms HP C does not support the long double _Complex type where the real and imaginary component are 128-bits in size. As HP C requires that each component of a long double _Complex be the same size as a long double, this compilation must specify the option to treat long double as 64-bits. User Action Either specify the correct compiler option or use the double _Complex type instead of the long double _Complex type.
