Hello,

a few weeks ago i installed SmartEiffel Release 2.3 on my Windows 7 Starter Netbook. All programs that i wrote
compiled well.
But then i tried to compile the example1 programm im the tutorial/xml directory and got these strange errors:

cpp: show_xml1.c:4698 Macro redefinition of MAKEWORD, previously defined in c:\lcc\include\win.h 547

This is the source of the program:

                display_node(node.child(i), indent + 1)
                i := i + 1
            end
        end

    error (line, column: INTEGER) is
        do
            std_error.put_string(once "Error at ")
            std_error.put_integer(line)
            std_error.put_string(once ", ")
            std_error.put_integer(column)
            std_error.put_string(once "!%N")
            die_with_code(1)
        end

end

I tried to find out which statement causes the error. I disabled the line
"create tree.with_error_handler(in, agent error)". The program compiled now, but of course it can not work properly without this statement.

Does anybody know, why i am getting these errors?  What can i do?

Dear Eiffel users, hackers, and believers,

We are happy to announce the birth Liberty Eiffel.

Liberty Eiffel is born from a simple idea: the Open Source and Free
Software community needs a free-as-in-freedom Eiffel compiler that
tries to be follow the principles that made Eiffel so appealing.

SmartEiffel is an academic project; as such it is a tool for its
developers to test and prove ideas that made their way into papers;
such a goal naturally requires the development model to follow the
rules of the academia, for example keeping all the coding in-house.

We are designing and developing an Eiffel compiler, compatible with
SmartEiffel, but with different goals:

- keep the language and the required run-time system as simple as
  possible;

- stick to the same high quality requirements that make SmartEiffel
  such a good piece of Free Software;

- "exit the ivory tower", being a community-driven project without the
  requirements of academic goals; being easily or automatically
  interoperable with most mainstream languages (C, Java, .NET...) is
  an absolute need;

- "stand on the shoulder of giants", using the Low Level Virtual
  Machine compier infrastructure (http://www.llvm.org) for the
  backend;

- "provide the batteries", without "reinveinting the wheel"; the best
  compiler in the world is useless without a wide set of libraries;
  there is a huge set of free-as-in-freedom libraries that many
  programmers and developers would like to use in Eiffel;

- give simple technical means to add more bindings and/or wrappers;

- maintain a simple and understandable design, striving to write the
  most excellent Eiffel code;

- be available on most platforms.

Liberty is a community-driven project. You are invited to participate
and test your own ideas. It's very easy: the code is shared on github.

Liberty is only beginning. We need you.
