Hello,

I found that the option -Dkind8 was removed in the latest makefile (5.2.11). Is it really necessary?

Thanks.

-Dkind8 means that your fortran compiler will use 8-byte (64-bit) reals in the compiling. This shouldn't be a problem to omit, provided you are compiling with the right libraries and such, as the 64-bit systems will default to already using the appropriate real-number precision.

Hope this helps.
