I am having the hardest trouble trying to run SWI-prolog on my Mac.
When I type:
/opt/bin/local/swipl
I get an error saying:
/opt/local/bin/swipl: No such file or directory
When I just type "swipl" I get:
swipl: command not found
I've tried this on both terminal and XQuartz. I've even gone into
/Applications/SWI-Prolog.app/Contents/MacOS
to see if that would do anything, however the prolog "Welcome" text never appears. Quite possibly the closest I ever got it to work was when I typed "pl" when inside the MacOS folder. However I was left with my terminal doing nothing and had to use Crtl-D.
Is there something I'm doing wrong? Did I install something incorrectly?
I'm running on a Mac OS X 10.9.1 Mavericks. I placed the SWI-Prolog application into my application folder and I also downloaded XQuartz per recommendation by the website.
If you have Homebrew installed, you can simply run
brew install swi-prolog
from Terminal, which will build it from source in one command.
You can then run the interpreter using swipl
.
