8.2 Generating IDL mappings

This template generates a source file containing the native type definitions for all IDL types defined in the .gen input file. By default, types are generated for the codels language (defined in the .gen file) for the first available component. This can be changed with the -l option. The generated mappings are output on stdout.

Additionnaly, a dependency file suitable for inclusion in a Makefile can be generated. This is controlled by the -MD, -MF and -MT options. These options are documented herafter, and follow the same syntax as the same options of gcc.

Example:

     user@host:~$ genom3 mappings demo.gen > demo_c_types.h
     user@host:~$ genom3 mappings -l c++ demo.gen > demo_cxx_types.h

Supported options:

-l
--language=lang
Generate mappings for language
--signature
Generate codel signatures and types mappings
-MD
Generate dependency information (in out.d)
-MF=file
Generate dependency in file instead of out.d
-MT=target
Change the target of the dependency rules
-h
--help
