As a side remark:
"gcc" on macOS is actually a version of "clang". This version has been modified by Apple to remove support for OpenMP. There are work-around for using OpenMP with Apple's clang, or you can configure Cactus without OpenMP. The recommended solution is to install gcc instead, following Roland's pointers.

Hello Lorenzo,
Thank you for your email.
Looking at the errors and the fact that it used the clang compiler I would suspect that the issue is with using clang.
We document how to use gcc on macOS and I would suggest you try this first.
You can find instructions at the top of the "New user tutorial" notebook:
https://github.com/nds-org/jupyter-et/blob/master/tutorial-server/notebooks/...
in the "Prerequisites" section.

On Mac, please first
Install Xcode from the Apple App Store. In addition agree to Xcode license and install the Xcode Command Line Tools in Terminal sudo xcodebuild -license sudo xcode-select --install when using MacPorts install MacPorts for your version of the Mac operating system, if you have not already installed it (https://www.macports.org/install.php). Next, please install the following packages, using the commands: sudo port -N install pkgconfig gcc11 openmpi-gcc11 fftw-3 gsl jpeg zlib openssl zlib bash subversion ld64 # required of macOS Monterey, see https://gcc.gnu.org/bugzilla/show_bug.cgi?id=102992 sudo port -N install hdf5 +fortran +gcc11 +openmpi configure.env="GFORTRAN_UNBUFFERED_ALL=1" sudo port select mpi openmpi-gcc11-fortran sudo port select gcc mp-gcc11 when using HomeBrew install HomeBrew for your version of the Mac operating system, if you have not already installed it (https://brew.sh/). Next, please install the following packages, using the commands: brew install fftw gcc gsl hdf5 hwloc jpeg open-mpi openssl zlib pkg-config bash subversion--8<--

Hi, I'm trying to build the EinsteinToolkit running the command:
./simfactory/bin/sim build -j2 --thornlist ../einsteintoolkit.th.
on my mac but the result, after nearly 1h, is the following:

Is there a way to make it work?
I'm using a macbook air (2017) with macOs monterey 12.3 and xcode 13.3.
the gcc version is the following:
Apple clang version 13.1.6 (clang-1316.0.21.2)
Target: x86_64-apple-darwin21.4.0
Thread model: posix
InstalledDir: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin
Best regards,
Lorenzo.
