[FLASH-USERS] Paramesh error

[Petros Tzeferacos]

Hi Youngjun,

I have seen this error with gcc 4.9.1 when filling guard cells. The two
options you have for this is to either degrade to an older version (4.7
should be ok), or compile without optimization the mpi_amr_1blk_guardcell.
Add the following lines in the end of your makefile:

#----------------------------------------------------------------------------
# Fake existence of iso_c_bindings module to prevent unnecessary
recompilations.
#----------------------------------------------------------------------------

ifeq ($(FLASHBINARY),true)
iso_c_binding.mod :
        touch $@
#gcc version 4.9.1 results in MPI communication errors
#unless we compile with -O0
mpi_amr_1blk_guardcell.o : %.o : %.F90
        $(FCOMP) $(FFLAGS) -O0 $(F90FLAGS) $(FDEFINES)  $<
endif


Please let us know if this works for you. We will try to come up with a
more elegant solution in the upcoming releases.

Best,
-- Petros
