Dear All,

I am struggling to compile FreeFem on arch-linux. I have compiled FreeFem on ubuntu 18 multiple times following [this](http://jolivet.perso.enseeiht.fr/FreeFem-tutorial/main.html#%5B197,%22XYZ%22,28.35,272.13,null%5D) tutorial; however, it does not seems to work on arch-linux. Any kind of help is appreciated!

In `configure.log`, you can see:

```auto

```

So there is a bug in your compiler. Any chance you could try another one?

Also, you could use `--disable-fortran` when configuring FreeFEM, then PETSc will use SuperLU\_DIST as an alternative to MUMPS for parallel direct solver.

Thanks for the quick reply and the tips.

It turned out that this behavior could be resolved by upgrading/updating gcc and gcc-fortran with pacman. Now I managed to compile PETSc successfully.

However, during the FreeFem compilation, I get the following error:

This seems to be a similar type of error; however, now all the compilers are installed with gcc version 11.2.0. Do you have any suggestion how this error could be resolved?

Edit: this try was with running `make -j8`. Trying once again with `make clean` + `make -j4` I am getting a similar error but elsewhere:

That’s weird, I’m using those compilers on both Windows and Linux (Debian) with no error. Could you please simply try with `make -j1` and copy/paste the first error you get?

Thanks for the tip. Compiling with `-j1` gives the following error :

I checked and `mpicxx` also seems to be up-to-date.

Well… maybe it’s up to date, but it’s bugged. Does `plugin/mpi/PETSc.cpp` compile?

Does this contain anything meaningful? The undefined control sequence is `echo \{ include \"$i\"\;\}\; ;\`

Ah, OK! Then everything is alright. Everything after `finish compile load mpi solver!` is just gibberish.

Wow, I have received to many errors in the past few days, I did not realized that the compilation was successful. I guess the conclusion is that changing version for only one compiler is dangerous, and everything needs to be clean (there were also other issues, e.g., not properly uninstalled automake, etc.). I will stick to compilation with `make -j1` on this machine.

Thank you really much for the help!
