[Gfs-users] Problem building from source - GTS & Gerris on Centos 7

[Himakar Ganti]

Hello Gfs-Users,

I am trying to locally install Gerris to my account on a HPC cluster (Red-Hat distro):

$HOME/usr/local/gerris

I was able to successfully install GTS package & and append it to the $PATH. I have tried the CFLAGS option as shown below and previously suggested in the forum:

./configure CFLAGS=-fPIC —prefix=$HOME/usr/local/gerris

and end up with the following errors in the make process (items in bold appear in red):

init.c:33:0: warning: "_GNU_SOURCE" redefined

 # define _GNU_SOURCE

 

<command-line>:0:0: note: this is the location of the previous definition

init.c: In function 'gfs_init':

init.c:416:5: error: implicit declaration of function 'MPI_Errhandler_set'; did you mean 'MPI_Errhandler_free'? [-Werror=implicit-function-declaration]

     MPI_Errhandler_set (MPI_COMM_WORLD, MPI_ERRORS_ARE_FATAL);

     ^~~~~~~~~~~~~~~~~~

     MPI_Errhandler_free

cc1: some warnings being treated as errors

make[3]: *** [libgfs2D_la-init.lo] Error 1

I do need MPI support to run. Can someone please help me with the install process?

Sincerely,
Himakar Ganti
