When I do `make check` I get FAIL in example/ed/schwarz-nm-3d.edp while loading “metis”
The error is:
dlerror : metis.so: cannot open shared object file: No such file or directory
list prefix: ‘…/…/plugin/seq/’ ‘’ list suffix : ‘’ , ‘.so’
current line = 62
Load error : metis
line number :62, metis
error Load error : metis
line number :62, metis
code = 2 mpirank: 0
However, metis.so is present in /plugin/seq/.
Also I have a lot of XFAIL. Is that normal?

I solved this issue.
cp plugin/mpi/metis.so plugin/seq/metis.so .

Thank, but it does not work for me. metis.so is already present in /plugin/seq/
I have digging a little more and I have found a more precise error:
```
load error : metis
fail :
```
dlerror : /home/earanda/software/opt/lib/ff++/4.2-1/lib/metis.so: undefined symbol: METIS\_PartMeshNodal
Any hints?

Go to your Freefem source directory (not install directory) and go to plugin/seq, then type ldd metis.so. Next go to plugin/mpi, then type ldd metis.so. Strangely only ${top-of-tour-Freefem-source directoryplugin}/mpi/metis.so is linked with libmetis.so. Now remove plugin/seq/metis.so and cp plugin/mpi/metis.so to plugin/seq then go to top of your Freefem source directory and type make check. In my case it reduce a number of fail and xfail tests.

In my case, none of metis.so (in plugin/seq and plugin/mpi) are linked with libmetis.so. The command ldd metis.so in plugin/seq produces

Then first, you should remove both plugin/seq/metis.so and plugin/mpi/metis.so.
Second, view where-library-config or where-library, then you can see both metis LD and parmetis LD. (I think when freefem compiles metis.so plugin, it uses parmetis LD instead of metis LD.)
Third add -lmetis to parmetis LD and go to top of source directory.
Finally, go to the top of source directory and type make and make check.

Thanks a lot @pistatex, it works perfectly fine.
