Trouble setting up jFlex

I wanted to use jFlex. Tried to search online tutorials. But all points to the same link. I could not successfully set up and use Flex on my machine. It would be great if some one could point me to a good tutorial.

Thanx in advance.

Solution

  • I have set this up recently on my 64 and 32 bit windows 7 systems. Here's what I did:

    1. Installed the extracted JFlex under my C:.
    2. Went into the bin folder (C:\jflex\bin) and edit the JFlex.bat file in my Notepad++
    3. There are two paths that need to be edited "JFLEX_HOME" and "JAVA_HOME".
    4. Because of my folder structure, I don't have to change "JFlex_HOME", but depending where you have installed it you may need to point to a different directory.
    5. JAVA_HOME - You have to browse your programs directory and find your java jdk installation. My JAVA_HOME variable is as follows: set JAVA_HOME="C:\Program Files\Java\jdk1.6.0_20"
    6. Save changes and run the jflex.bat program in the cmd pmt and you should be good to go.

    I hope this helps.
