Yes, what are the current values if these variables ?

The `$FF_DIR` is located properly in the `~/FreeFem-sources`.  
The $PATH is my path, but the `$FF_INCLUDEPATH` and `$FF_LOADPATH$` are not defined

Hence explaining why you fail to run a script as simple as `load "PETSc"` on your own.

Thank you @prj!  
I set a `~/.freefem++.pref` file as follows:

```auto
loadpath = "~/FreeFem-sources/plugin/seq/"
loadpath += "~/FreeFem-sources/plugin/mpi/"
includepath = "~/FreeFem-sources/idp/"

```

and now I can load some packages, also `PETSc` with `ff-mpirun`.

Unfortunately there are some other that are still missing. I found that `mshmet` and `ff-Ipopt` and `ff-Nlopt` are not found. Do you have any idea why it happened?

You can go into each specific folder of plugins you need in `3rdparty` and do `make`, then re-do `./reconfigure` at the top and you should be good to go.

Thanks a lot @prj, now it’s working properly!
