Dear Sir/Madam
I am trying to compile a Cactus executable on my laptop, which has an
ubuntu-based operating system(Ubuntu 18.04). I am using the latest version i.e; ET_2019_10. I am using simfactory and following the Simulation Factory Advanced Tutorial. For building, I am using generic configuration files which are also the default files.
Here are the steps I am using:
simfactory/bin/sim setup
./simfactory/bin/sim build -j2 --thornlist ../einsteintoolkit.th
Compilation produces an executable, but when I go for running the
example file using the command,
exe/cactus_sim
I get the following error.
""

I am not able to find any relevant solution on the internet. Can you
please help me find in the solution.
Yours Sincerely,
