SmartEiffel The GNU Eiffel compiler is the fastest and the slimmest multi-platform Eiffel compiler on Earth! It is also completely FREE!
SmartEiffel The GNU Eiffel Compiler is a free open-source Eiffel compiler and a set of tools for Eiffel software production, distributed under the terms of the GNU General Public License as published by the Free Software Foundation.
SmartEiffel is available for a very wide range of platforms. In fact, SmartEiffel should run on any platform for which an ANSI C - POSIX compiler or a standard JVM exists.
The current distribution includes an Eiffel to C compiler, an Eiffel to Java bytecode compiler, an Eiffel code debugger, a documentation tool, a pretty printer and various other tools, as well as a very large library of general purpose Eiffel classes. Of course, the source code for all this is provided.
