errors in running step-18 within Xcode

[Alberto Salvadori]

Dear community

I successfully installed 9.3 on my mac M1 from the dmg . However, I am at present unable to run examples, as for the step-18. For this reason, I share my attempts. 

I am using Xcode 12.5.1 (12E507) on BigSur 11.2.3 (20D91).

After opening a deal.ii terminal from deal.ii.app, the step-18 code compiles well both inside Xcode and from Makefile. When it comes to run the executable, neither of the two apparently work. The output message from terminal is

bash-3.2$ ./step-18 

Illegal instruction: 4

whereas the debugger provides some further notifications, as in figure, which I am not able to discern. 

I had at my disposal a former installation of deal.ii.9.2, that I made with spack and gcc in a rosetta terminal. In such a case, within a rosetta terminal, the step-18 compiles and runs well. Note that deal.ii9.3 does not open a rosetta terminal.

Hope these evidences can be of help.

Best and thanks, as always!

Can you open a Rosetta terminal and follow the instructions to parse deal.ii init files? I think it is just the fact that you are not running under Rosetta, but cannot confirm...

Luca,

this is what I have done, if I got what you meant:

1. opened a Rosetta terminal

2. /Applications/deal.II.app/Contents/MacOS/dealii-terminal

      ______           _  _____ _____

        |  _  \         | ||_   _|_   _|

        | | | |___  __ _| |  | |   | |

        | | | / _ \/ _| | |  | |   | |

        | |/ /  __/ (_| | |__| |_ _| |_

        |___/ \___|\__,_|_(_)___/ \___/

This is a bash shell with CMAKE_PREFIX_PATH and DYLD_LIBRARY_PATH set to work

with Deal.II. A full spack installation with deal.II is available under 

    /Applications/deal.II.app/Contents/Resources/spack

If you want to set up your daily Terminal to work with deal.II, add these lines

to your ~/.profile (or ~/.zshrc, if you prefer zsh):

   export DEAL_II_CONF_SILENT=ON    # Turn off this message

   . /Applications/deal.II.app/Contents/MacOS/dealii.conf

deal.II and all its dependencies were installed using spack, and are also

available through spack, e.g.:

    spack find # Shows all installed packages

You can find the deal.II examples directory under 

    /Applications/deal.II.app/Contents/Resources/Libraries/share/deal.II/examples

3. cmake -G 'Unix Makefiles'

4. make release

5. make

6.  ./step-18 

Illegal instruction: 4

Actually, not exactly. The instructions are i the screen shot. 

Open a Rosetta terminal, and then source the conf file, i.e.

.    /Appl..../dealii.conf

The command you called opens a normal terminal, and then sources the conf file.

Hi Luca,

thanks for clarifying. Still not succeeded, see below.
