Could not run elki.sh in mac OSX

In order to use ELKI to do a clustering task, I have downloaded the latest complete release package: elki-0.7.1

The README.PDF says to run elki.sh on OSX. However, after I run the elki.sh with Terminal, it pops the following error:

Error: Could not find or load main class de.lmu.ifi.dbs.elki.application.ELKILauncher

I am sure I have downloaded the complete packages entirely, but still could not run ELKI successfully. Thanks in advance!

Solved

I will show below how you can install Elki in macOS, El Capitan Version 10.11.6.

Installation of ELKI in macOS

brew cask install java

git clone https://github.com/elki-project/elki.git

cd elki

./gradlew shadowJar

./gradlew build

open elki-bundle-0.7.2-SNAPSHOT.jar

enter image description here

where you can see the ELKILauncher.

Example that ELKI is working just fine

You don't have to configure any paths, actually. Questions you may want to ask yourself are

  • Did you build the Elki on the command line?
  • Do you have the correct Java? You can install it easiest with brew as shown above.

If you get the single-jar, you should simply be able to run the jar without the script. Or you could clone the git project in Eclipse and run it. Make sure you have the path names correct, and try using bash to run the script. OSX choices are sometimes a bit odd. Open the script in an editor, and adjust it to your needs (it's a script)

Can't access property inside object initializer

Consider the following code. List files = new List (); .... while (reader.Read()) { var a = new MyFiles { FileName = reader["Filename"].ToString(), FileLocation = reader["Filelocation"].ToString(), FullPath = FileLocation + @"\" + FileName // Error at this line }; files.Add(a); } The above is a snippet from my method which uses SqlDataReader to fetch data from the database. Everything works fine expect when I try to assign value to FullPath property I get the following error message: An object reference is required for the non-static field, method, or property 'MyFiles.FileLocation' An object reference is required for the non-static field, method, or property 'MyFiles.FileName' I know I can make those properties static or create an instance and access them via e.g. var b = new MyFiles(); b.FileLocation .. But my question is why can't I use FileLocation and FileName as I am in t...
