[FLASH-USERS] looking for help

[Dean Townsley]

Hi Zhang,

It looks like your compiler flags are probably not appropriate for your
compiler.

Assuming that you are using a gnu compiler stack (i.e. gfortran) the
flags I use are:

FFLAGS_OPT = -c -O3 -fdefault-real-8 -fdefault-double-8
-ffree-line-length-none
FFLAGS_DEBUG = -g -Warray-bounds -c -fdefault-real-8 -fdefault-double-8
-ffree-line-length-non
e
FFLAGS_TEST = -c -fdefault-real-8 -fdefault-double-8 -ffree-line-length-none

These are basically the same as those in the
sites/Prototypes/Linux/Makefile.h.gfortran file included with the
distribution. If you are using gnu compilers, you should take that as
your starting point for getting a working Makefile.h rather than the
plain sites/Prototypes/Linux/Makefile.h one.

I hope that helps.

Dean
