[FLASH-USERS] How to install FLASH4.6 in centOS

[Ryan Farber]

Hi Zhang,

It sounds like there is an issue with the Makefile.h in your
/...path_to_flash/sites/your_hostname/Makefile.h file. (Though, if you
haven't created a directory in sites matching your hostname then it'll use
the Makefile.h in sites/Prototypes/Linux/ (unless that has changed between
4.2.2 and 4.6)).

Have you updated the Makefile.h with the new paths for mpich, hdf5, etc It
sounds like you have since it compiled successfully.
The warnings suggest you may have forgotten to modify FFLAGS_OPT. I'm not
intimately familiar with compiler options, but I use -r8 to make fortran
reals default to double precision.

I haven't seen your runtime error before, but think it would be a good idea
for you to look over your Makefile.h (double check MPI_PATH or MPI_HOME
(whichever is used later on), HDF5_PATH and so on are correct for the
system, double check FCOMP, COMP, CPPCOMP, LINK have correct paths for the
system, and that FFLAGS_OPT (or FFLAGS_DEBUG if you're using '-debug' setup
option) and CFLAGS_OPT have the desired compiler options.

Best,
--------
Ryan
