[FLASH-USERS] Fwd: Flash Compilation Problem

[Ryan Farber]

Hi Sonu,

1. This should serve as a friendly reminder to always "reply all" if you
want to enable help from all flash-users ;)
2. There is a quickstart in the user's guide (which you can find on the
FLASH website) but generally to get started you should:

i. Submit the code request, and then after receiving your password,
download FLASH [which you probably have done already]
ii. tar xvzf FLASH4.8.tar.gz
iii. Set the paths for your system in Makefile.h (as Xu mentioned). If you
have already run the setup command, your object directory probably has a
soft link, which can show you the path to the original file (or you can use
the soft link to open Makefile.h). Otherwise, if you look in your "sites"
folder (inside of FLASH4.8) then you can either create a directory matching
your machine's hostname and modify a Makefile.h in there, or modify the
appropriate Prototypes subfolder's Makefile.h

Regarding what to modify in Makefile.h, generally you'll need to update the
MPI_PATH (and sometimes MPI_HOME, MPI_BIN, etc.) to point towards where you
have MPI installed. You typically will also need to update HDF5_PATH (or I
guess HDF4_PATH or the variable for netcdf). Make sure the fortran, C, and
C++ compilers are set to appropriate values.

iv. Back in your FLASH4.8 directory, run setup (for the Sedov problem for
example since I think it is still the de facto FLASH test problem): ./setup
Sedov -auto 2>&1 | tee OUTERR_SETUP.txt

v. cd object; make 2>&1 | tee OUT_MAKE.txt
-> You can also do parallel make of course.

If you run into issues, kindly attach the output of OUTERR_SETUP.txt as
well as OUT_MAKE.txt, in addition to describing what you tried and what you
think went wrong.

Best wishes,
--------
Ryan
