GLD Green Light Simulator not compiling

Question

I found a traffic light simulator called Green Light District the file I download included and explanation of how to build the project and it says the following

Extract the archive to a certain directory,
In that dir do javac gld/*.java
In that dir do java gld.GLDSim

I know * means all but... first I want to know am I able to compile something like *.java this is a link to the simulator , if some one can tell how to compile it , it would be really nice http://sourceforge.net/projects/stoplicht/

Answer 1

The issue occurs due to the fact that "enum" became reserved word in Java 1.5+, so it can no longer be used as a name for variables/methods/classes, but GLD uses enum as a name for some variables.

Once the name is changed - project will compile.

Alternatively one can try to compile it with compiler setting source version 1.4 - this should probably also work, but I suggest to simply rename all variables named enum.

Answer 2

Basically, all the code is in the folder called gld. You need to compile all the .java files inside it. After that, you run the main class gld.GLDSim.

Answer 3

Had the same problem. You should use Java 1.4, this simulator is quite old, hence uses an old version of Java and some preserved words in more advanced Java versions.
