[cdt-dev] Adding new resource types to CDT

[Lars.Kurth@xxxxxxxxxxx]

Hi,
I was wondering how it is possible to
add new resource types to the C/C++ Projects
View. A bit of background:

Resources in the can be of several types:

• Sources and directories that are build configuration invariant
• Binaries and files that are build configuration dependant. They are stored in a configuration dependant directory. Because of this, they behave as if they were configuration invariant.
• Resources which are dynamically created on demand, for example the Includesresource or fragments of source files. These are “virtual” resources that do not necessarily map onto entities that exist in the file system and are implemented by CDT itself.

We need to support some source files
- DEF files - that depend on the build configuration. The background is
that DEF files contain mangled names of C++ symbols, which depend on the
toolchain that is being used. So what one ends up with is typically several
build configurations sharing one DEF file. There are two ways how to integrate
this from a users point of view:
(a) Add all source files as separate
entities to the project and let the builder ignore the ones that are not
applicable for a particular configuration. That should be straightforward.
(b) Add one source file and link it
to the correct source file whenever the build configuration changes

I have only just started looking at
the packages org.eclipse.cdt.internal.ui.cview and the CDT core model (CoreModel
and CModelManager). What is the best way to achieve (b) and which places
should I start to look at for a more detailed investigation? Is this possible
at all without changing the CDT core model (via extension points or by
deriving a specialised C/C++ Project View from CDT classes and the CDT
core model)?

Any help would be appreciated.

Best Regards
Lars Kurth
P.S.: This seems to be a similar problem
to the one described in the thread "[cdt-dev] Towards a more language
neutral CDT"
