Green Hills MULTI
|
|
|
|
|
-----------------
|
|
|
|
|
|
|
|
|
|
Generates Green Hills MULTI project files (experimental, work-in-progress).
|
|
|
|
|
|
|
|
|
|
The buildsystem has predetermined build-configuration settings that can be controlled
|
|
|
|
|
via the :variable:`CMAKE_BUILD_TYPE` variable.
|
|
|
|
|
|
|
|
|
|
Customizations that are used to pick toolset and target system:
|
|
|
|
|
|
|
|
|
|
The ``-A <arch>`` can be supplied for setting the target architecture.
|
|
|
|
|
``<arch>`` usually is one of ``arm``, ``ppc``, ``86``, etcetera.
|
|
|
|
|
If the target architecture is not specified then
|
|
|
|
|
the default architecture of ``arm`` will be used.
|
|
|
|
|
|
|
|
|
|
The ``-T <toolset>`` option can be used to set the directory location of the toolset.
|
|
|
|
|
Both absolute and relative paths are valid. Relative paths use ``GHS_TOOLSET_ROOT``
|
|
|
|
|
as the root. If the toolset is not specified then the latest toolset found in
|
|
|
|
|
``GHS_TOOLSET_ROOT`` will be used.
|
|
|
|
|
|
|
|
|
|
