[FLASH-USERS] Library conflict at the end of make and segmentation fault

[Mattia Cipriani]

Hi,

I am recently experiencing some issues with FLASH 4.7.1 simulations, after updating from FLASH 4.5.
I am using the same site-specific Makefile.h which was working before, since the configuration of the cluster did not change from the past.
Also the compilers are the same as before.
I use the setup script to collect all the needed files and objects for compiling the simulation and then I use make to compile it.
At the end of the execution of make, I get the following warning

/bin/ld: warning: libgfortran.so.4, needed by /usr/mpi/gcc730/openmpi-3.1.2/lib/libmpi_usempif08.so, may conflict with libgfortran.so.3

If I run the flash4 executables with mpirun it starts to run ok, but at some apparently random point of the simulation I get a segmentation fault error.

I am wondering if the warning from make could be the reason for the segmentation fault error.
How can I solve the warning?
I know it is a linux-related question rather than a FLASH problem, but I would be glad if you can help or at least give me a feedback if the segmentation fault error might be due to the warning from make.

Best regards,
Mattia
