I know it might be not the best place for this question but,am doing a master thesis on Smart Traffic controllers , I found this simulator which is written in java, it has been used in many papers I've read , but for some reason I can't/it wouldn't be compiled , anyone can tell me why ? it can be found at
This was made with an old version of Java (pre 1.5) It uses enum as a variable name. Need to as (javac tells you) give command :
javac -source 1.4 gld/*.java
Note : when passing a path to Java both slashes work in Java
If your getting file not found your probably in the wrong folder.
Download a zip to a place lets say to folder:
D:\\prog\\j\\
Now open command prompt, I assume you have java bin JDK in windows PATH?
So now you have default source download zip
gld_rel131_source.zip
in D:\\prog\\j\\
Give following commands :
D:
cd D:\\prog\\j\\
mkdir traffic2\\src
cd traffic2\\src
jar xf D:\\prog\\j\\gld_rel131_source.zip
mkdir ..\\bin
javac -d ../bin -source 1.4 gld/*.java
cd ..\\bin
java gld.GLDSim
When you run javac gld/*.java
, you get this kind of error:
./gld/algo/tlc/SL2TLC.java:272: as of release 5, 'enum' is a keyword, and may not be used as an identifier
(use -source 1.4 or lower to use 'enum' as an identifier)
Enumeration enum = count.elements();
As specified in the error message, add -source 1.4
:
javac -source 1.4 gld/*.java
And everything will be OK :)
You encounter this error because this project is old (2005), was written for J2SE 1.4 or former versions. enum
, which used as a variable name in the project, is a keyword since J2SE 5.0. Thus, it cannot compile using newer versions, since its usage is reserved.
EDIT
Since your system is Windows, I would use a backslash ( \\
) instead of a slash ( /
) for the path argument:
javac -source 1.4 gld\*.java
EDIT 2 Actually it looks like you were in the wrong directory ( gld/
instead of its parent). Simply cd ..
and retry.
