Static Library Support: Project dependency to static libraries

Last time I was dealing with the project build types that allowed DDT to produce static libraries out of a project. That’s a vital element for a larger project infrastructure so its implementation should be priority. This time there was an other problem related to the larger projects. It’s all nice and good to have lib files produced but we couldn’t really do anything with them at all.

Actually, the same way as most of my development I heavily relied on what Bruno did before. As far as I understood the already existing code the heavy lifting was already done. That is, the project dependencies on libraries were implemented as a skeleton, only that it wasn’t useful… yet. The only thing left to implement is to use the project dependencies’ output (the static libraries themselves) as input modules and their source directory as input directory on the referee project. But nothing is as easy as it looks. I’ve just encountered a quite disturbing fact: the DLTK documentation is just virtually non-existent. There are some vague articles in their wiki, but the API documentation is basically isn’t any useful. That makes life quite hard to develop anything on the DLTK basis and frankly I’m worried about the scenario when DDT hit huge problems with the DLTK. The actual issue I encountered looked quite easy: how can I get libraries from a different project and resolve their paths relative to the workspace. At this point of time I didn’t find anything useful for this. So at the time being I had to hack the references to other projects with a simple “../[projectname]/src” as an  import directory and “../[projectname]/lib/[projectname].lib” as a input file. But the real solution would be to get access to the other project DeeBuildOptions object which could provide me the necessary settings for the output file, its build type from its IScriptProject info the source folders as they could be more than one.

In other words, to use this new feature the user has to make sure that the directory structure is that of the default and there are no additional source folders. Also it probably won’t work with anything but DMD and possibly only on Windows. The next target is to eliminate these problems.

The corresponding change set in the source code: r341098a21488
