ITK/Release 4/Wrapping/BuildProcess

Wrapping build is done in several steps.

Configuration

This is done with CMake. During this step, the template instantiations are generated by parsing the files in Wrapping/WrapITK/Libraries. For each macro call of the template instantiation process, some callback macros specific of each language generator are called to generate the files and the commands needed to build the wrappers.

Template instantiation

Everything is done in the 'Libraries' directory. The instantiations are separated in two levels:

• the libraries, which are grouping several modules. Generally, one binary for a target language contains all the instantiations from one library;
• the modules, inside those libraries. Each module groups several template instantiations. The swig interface generator generates one '.i' file per module.

Several macros are available to simplify the template instantiations.

Macros

The macros are defined in 'TypedefMacros.cmake'.

WRAP_LIBRARY and END_WRAP_LIBRARY

Formely BEGIN_WRAPPER_LIBRARY and WRAPPER_LIBRARY_CREATE_LIBRARY.

AUTO_INCLUDE_MODULES

Formely WRAPPER_LIBRARY_CREATE_WRAP_FILES.

INCLUDE_MODULE

Formely INCLUDE_WRAP_CMAKE.

Code generator

Everything is done in the 'Languages' directory.
