[antlr-interest] Java to C# translation

[Addi Jamshidi]

I am new to ANTLR (in fact very new)..
I am trying to convert a number of existing Java
classes into C#, and after reading the ANTLR web site
I am under the impression that:

This can be done, and in fact what Mr.  Michael J. has
provided can do this.

If my assumption is correct I have the following
questions (what do I need to run for this to happen?):

1) I did download the antlr-2.7.2a2-CSharp.zip file.
And tried to follow the instructions for building it.
However I have been getting tons of errors (e.g.
classes not found, Load exception errors, etc.). The
doc says to run  build.bat from the antlr top
directory. I have done that, in fact I have tried
running the build files from every directory there is,
and still I get the similar errors.

2) I then downloaded antlr-2.7.0.zip and installed it.
And then unzipped antlr-2.7.2a2-CSharp.zip for its
contained files to be copied in the directory tree
that antlr-2.7.0.zip created. Then I copied all the
build files into the antlr directory (i.e.
antlr-2.7.0\antlr directory), and then tried running
build.bat. 

3) This time it did work better, however I am still
getting 33 errors during the build (some of which I
have included at the bottom of this email)...

So my questions are:

1) Is it true to assume that given a .java file, I can
convert that to C# (completely or partially) using
antlr-2.7.2a2-CSharp.zip?

2) If so how can I use it (i.e. what do I need to run
for this to happen)?

Many thanks in advance,

Addi Jamshidi


P.S - Here are a few of the errors I am getting during
the build per explanation given earlier...
