Nothing odd here, but providing instructions is never a bad idea. Note that ORCA is binaries only i.e. no source code. It's one reason why I wouldn't want to rely on it as my main code for computational chemistry. However, I am interested in using it to compare select results from nwchem and g09, especially in cases where g09 and nwchem produce differing results.
Either way,. to download ORCA you need to join the ORCA forum:
https://orcaforum.cec.mpg.de/portal.php
Once you've joined you can go to Downloads and, well, download. I went for https://orcaforum.cec.mpg.de/downloads.php?view=detail&df_id=43
The symmlink is there because debian already has a binary called orca.
And that's that installed. To add /opt/orca/orca_3_0_3_linux_x86-64 to PATH do
To test, try one of the jobs on https://www.sharcnet.ca/help/index.php/ORCA#Parallel_ORCA_job and run using
