[Users] Compiling Einstein Toolkit

[Edmond, Lawrence]

Hello,

I am Lawrence Edmond, IV, a rising third-year PhD student at Brown
University in the physics department. I am interested in using
EinsteinToolkit to simulate black holes with accretion disks for cosmo/dark
matter research.

I am following along with the Wiki
<https://einsteintoolkit.org/download.html> and the JupyterNotebook
<https://github.com/einsteintoolkit/jupyter-et/blob/master/tutorial-server/notebooks/CactusTutorial.ipynb>
on
git to compile and run the first "HelloWorld" Thorn before attempting to
write my own. Following along with the notebook. I am able to compile
EinsteinToolkit via the following bash command:

./simfactory/bin/sim build -j4 --thornlist ../einsteintoolkit.th

which differs from the notebook by the location of the "einsteintoolkit.th"
thorn. This is able to compile without errors however, when I try to run
the following command to create and execute the "HelloWorld" thorn,

./simfactory/bin/sim create-run helloworld \    --parfile
arrangements/CactusExamples/HelloWorld/par/HelloWorld.par

I get an error message saying that the executable cannot be found or was
not created (see below for a copy of the output).

[ledmond at login010 Cactus]$ ./simfactory/bin/sim create-run helloworld \
    --parfile arrangements/CactusExamples/HelloWorld/par/HelloWorld.par
Warning: Current Working directory does not match Cactus sourcetree,
changing to /users/ledmond/EinsteinToolkit/Cactus
Parameter file:
/oscar/home/ledmond/EinsteinToolkit/Cactus/arrangements/CactusExamples/HelloWorld/par/HelloWorld.par
Error: Executable /users/ledmond/EinsteinToolkit/Cactus/exe/cactus_sim for
configuration sim does not exist or is not readable
Aborting Simfactory.

I believe the issue is that the procedure is looking for the executable
file, and the associated folder to hold all created executables is being
created using a path that cannot be accessed on my cluster. That being
said, is there a way to manually change the path for the exe/ directory
that is created by Simfactory?

Thank you in advance for any help you may offer. Please do not hesitate to
contact me if you need any more information or further clarification to
address this compilation issue.
