Batch compilation

In order to launch a compilation without user intervention you need to specify the -batch switch in the ec command line, otherwise the Eiffel compilation will be blocked. We will present below a typical example of batch processing on both Unix and Windows platforms where we want to compile a project in both frozen and finalized mode, then to launch the C compilations. At the same time we want to save the output of ec and the C compilations.

Unix

In a file called launch_ec you can have the following: #!/bin/sh output_file="/output_path/OUTPUT" cd /your_project_path #Launch Eiffel compilation ec -batch -config config.ecf -finalize -c_compile 2> $output_file #Since only C compilation for finalized code is done #Launch C compilation for frozen code cd EIFGENs/target_name/W_code finish_freezing > $output_file

It will go the directory where your project is located and compile your Eiffel code using the config.ecf file located in your project directory and compile automatically the C code. All outputs will be stored in the file /output_path/OUTPUT.

Note: All output from ec are going to the error output, so do not forget to redirect the error output when you want to see the result.

Windows

In a file called launched_ec.bat you can have the following: rem Launch Eiffel compilation ec -batch -config config.ecf -finalize -c_compile > c:\output_path\OUTPUT rem Since only C compilation for finalized code is done rem Launch C compilation for frozen code cd EIFGENs\target_name\W_code finish_freezing > c:\output_path\OUTPUT

It will go the directory where your project is located and compile your Eiffel code using the config.ecf file located in your project directory and compile automatically the C code. All outputs will be stored in the file c:\output_path/OUTPUT.
