This chapter describes what code EWG generates and how to integrate that code into a automated build system.
The ewg tool is a command line application and takes the following command line parameters:
ewg [--version] [--verbose]
[--enable-msc-extensions | --disable-msc-extension] [--output-dir=<...>]
--cpp-full-header=<...> [--include-header=<...>] [--config=<...>]
options:
--version ... Output EWG version number
--verbose ... Output progress information on STDOUT
--enable-msc-extensions ... Enable Visual C++ extensions (default on Windows)
--disable-msc-extensions ... Disable Visual C++ extensions (default everywhere else :)
arguments:
--output-dir ... Directory where generated files will be placed
--cpp-full-header ... File name (including path name) to the already c preprocessed C header
--include-header ... Name of header file, that should be used in eiffel external clauses
--config ... Name of config file to use. A config file allows to customize the wrapping process
You can use ewg directly to see what it produces on a header of your own without setting up a complete project, or use your own build process. Most of the time you will not use the ewg tool directly, but use it indirectly through geant.
