Hello Karima,

please use the Einstein Toolkit users mailing list users@einsteintoolkit.org if possible for support questions.

It is usually also better to copy and paste the text of the error message rather than taking a screenshot since the former lets me copy and paste from what you entered while the latter requires me to retype evertyhing.

In your case:

* Sommerville is quite old (5 years) and not all options shown in the current tutorial notebook are supported * in particular the "-j" option to simfactory (to build in parallel using make's own "-j" option) is not supported * the easiest fix is to leave out the option "-j2" which will compile using 1 compilation process (so will be quite slow)

Hope this helps.

Yours, Roland

Dear professor Roland Haas,

I am having an issue in installing the Somerville release 2015 of the Einstein toolkit on Ubuntu 20.04. I get an error in configuring the ET using 'Simfactory'. The  error is  below

Command:

...

%%bash ./simfactory/bin/sim build -j2 --thornlist ../einsteintoolkit.th

Error:

...

CalledProcessError: Command 'b'./simfactory/bin/sim build -j2 --thornlist ../einsteintoolkit.th\n'' returned non-zero exit status 2.

The image of the output is also attached. I request your assistance to fix the error. I am sorry if this email is causing you any inconvenience.

Thank you,

Best regards

Karima shahzad
