I am trying to use lisp in linux but I can not get the listener to work.
Using Eclipse's menu, in help -> install new software, I installed the dandelion plugin but every time I try to run lisp code, like
(+ 1 2), something simple, I get the following errors:
Error in background evaluation java.net.ConnectException: Connection refused Error initialising connection java.net.ConnectException: Connection refused Starting eval server failed Cannot run program "/home/michael/.eclipse/org.eclipse.platform_3.8_155965261/plugins/de.defmacro.dandelion.env.clisp.linux.x86_2.49.2/binary/environment_clisp_2.49.2": error=13, Permission denied
I have tried running the command
sudo chmod + /home/michael/.eclipse/org.eclipse.platform_3.8_155965261/plugins/de.defmacro.dandelion.env.clisp.linux.x86_2.49.2/binary/environment_clisp_2.49.2
Yet I see no output, the terminal just goes to the next new line. I am running a 64bit ubuntu version 14. I am pretty new to all this but I would like to use linux as my main OS as it is quite convenient for school. If anyone has ideas please let me know!
I went in and manually edited the files permission to allow anyone to read and write. I now only get the errors.
