I installed Freefemv4.12 on my m2 mac and got the following error. Are there any libraries that need to be pre-installed? # filerc : .zprofile ./Install-app.sh: line 48: 1446 Killed: 9 /Applications/FreeFem++.app/Contents/ff-$ver/bin/FreeFem++ /Applications/FreeFem++.app/Contents/ff-$ver/share/FreeFEM/$ver/examples/tutorial/Laplace.edp Create Link of example and Doc /Users/iberico Error missing install missing lib ?? ---

You should compile from the sources: [GitHub - FreeFem/FreeFem-sources: FreeFEM source code](https://github.com/FreeFem/FreeFem-sources#freefem). The success rate is higher. ---

I have tried compiling from source code. However, the Automatic configuration part did not work. It says to enter “autoreconf -i” but I could not figure out how to install autoconf. Is it different from autoconf? ---

If you are using Homebrew, you could use `brew install automake`. ---

I was able to install automake from homebrew. In addition, the installation was performed including PETSc. Sudo make install has also been executed. However, when I ran “test.edp”, I got a segmentation fault and could not calculate. I typed “FreeFem++ test.edp” and ran it. If there are any additional options please let me know. ---

If you go into `examples/hpddm` and type `make check`, what do you get? ---

EXAMPLE was executed. The result was that all 106 files were SKIP. Since this is not an error, does this mean that the installation is working correctly? ---

No, they should not be skipped, they should pass. Did you properly followed all steps from `README.md` that I sent earlier? ---

I’m not sure I understand why you’d want me to send this file, it’s available on GitHub for everyone. ---

The command was executed again from the beginning. As a result, I ran “make check” on “examples/hpddm” and got “XFAIL” on all 106 files. Should I erase all files and start over? I have done up to make install, but how do I uninstall if necessary? ---

Sorry for all the trouble, I think this is not specific to your machine. For good measure, could you please try the following. ```auto $ cd examples/tutorial $ ../../src/nw/FreeFem++-nw Laplace.edp -v ``` Do you have a segmentation fault running this? If so, could you please try to start from scratch and do the following. ```auto $ rm -rf FreeFem-sources $ git clone -b develop https://github.com/FreeFem/FreeFem-sources $ cd FreeFem-sources $ autoreconf -i $ ./configure --disable-optim $ make $ cd examples/tutorial $ ../../src/nw/FreeFem++-nw Laplace.edp -v ``` If you don’t have a segmentation fault anymore, do the following. ```auto $ cd ../../ $ cd 3rdparty/ff-petsc $ make petsc-slepc $ cd ../../ $ ./reconfigure $ make $ cd examples/hpddm $ make check ``` Do you still get either `XFAIL` or `SKIP` then? ---

An error occurred at the following location. * * * ``` UNABLE to CONFIGURE with GIVEN OPTIONS (see configure.log for details): ``` * * * ``` Error running make on MMG ``` * * * PETSc installation has failed. The preceding “Laplace.edp” was executed successfully. ---

Could you please `rm -rf 3rdparty/ff-petsc/petsc-3*` and also delete the previous `ff-petsc` folder (presumably in `/usr/local/` if you didn’t configure with a `--prefix`) and try again? If it still fails, please send `3rdparty/ff-petsc/petsc-3*/configure.log`). ---

You need to attach the file. But first, please, try to tidy up your machine. 1. Why is there a reference to `/Applications/FreeFem++.app`? Remove that. 2. Remove `/Users/iberico/my_program/02_Freefem/FreeFem-sources`. 3. Remove `/usr/local/ff-petsc`. Then, restart from scratch. ```auto $ git clone -b develop https://github.com/FreeFem/FreeFem-sources $ cd FreeFem-sources $ autoreconf -i $ ./configure --disable-optim $ cd 3rdparty/ff-petsc $ make petsc-slepc $ cd ../../ $ ./reconfigure $ make $ cd examples/hpddm $ make check ``` ---
