Gerris practice

Some Gerris (Popinet 2003) codes.

Some tips and tricks:

1. Built-from-source code change: Line 416 of "init.c": change to:

MPI_Comm_set_errhandler (MPI_COMM_WORLD, MPI_ERRORS_ARE_FATAL);

2. Gerris-style syntax-highlighting: C-syntax is good enough. Follow these threads:

3. Possible error in some distros:

gerris: file `column.gfs' is not a valid simulation file
column.gfs:212:12: cannot load module: /usr/local/lib/gerris/libgfsview2D.so: cannot open shared object file: No such file or directory

Solution: make a symbolic link to the correct path:

sudo ln /usr/lib/x86_64-linux-gnu/gerris/libgfsview2D-0.0.1.so libgfsview2D.so

sudo ln /usr/lib/x86_64-linux-gnu/gerris/libgfsview3D-0.0.1.so libgfsview3D.so

Gfsview cannot be installed in Ubuntu 22.04 from source?

4. Gfsview compilation error for Ubuntu 22.04:

/usr/bin/ld: gfsview2D-main.o: undefined reference to symbol 'XSync'
/usr/bin/ld: /lib/x86_64-linux-gnu/libX11.so.6: error adding symbols: DSO missing from command line
collect2: error: ld returned 1 exit status
make[4]: *** [Makefile:395: gfsview2D] Error 1

Solution: include necessary libraries

./configure LIBS=-lX11
