    Hi all,

    first of all, thanks for your great job. I think that it is very useful.

    I tried to install the OpenCCG distribution by following the README instructions but I have an error message (see below).
    I am using a MacBook wth MacOSX 10.5

    Thanks in advance for any help.

    Alessandro

      Hi.

      I resolved the problem by building the OpenCCG from source. It seems to work now.

      Thanks for your work on OpenCCG

    Yes! I also resolved it the same way!

    I believe this is a Java 1.5 vs. 1.6 issue.  Glad to hear that recompilation solves the issue!

    I built the system with
    "ant"
    i did
    export OPENCGG_HOME="/Users/kappolo/Downloads/openccg/"
    export PATH="$PATH:$OPENCCG_HOME/bin"
    but now when I'm executing the command on the directory I get:
    andrea-biaggis-macbook-pro-4:tiny kappolo$ tccg
    -bash: tccg: command not found

    execute /Users/kappolo/Downloads/openccg/bin/tccg  XYZ
    on the prompt, where XYZ is your grammar.xml file (with absolute path)
    what do you get? If it works then tccg is there and working, all you have to ensure is you "export" the env variables properly!

    thanks,
    Raveesh

    Note that you should build from source using the ccg-build command, not invoking ant directly.  I've just updated the README in the latest cvs version accordingly.

    Also note that OPENCCG_HOME needs to be spelled exactly as shown, with the underscore and with CCG not CGG.
