I am working with Eclipse Luna with CDT plug-in. Whenever I build the project it keeps rebuilding all files, even if I just modify specific .cpp file. I use project -> build project for the build. I also removed build automatically option (and re-opened eclipse), but it did not solve the problem.
I've searched a lot for similar questions, but found none.
The File | New | C++ Project | Executable option creates a project in which CDT automatically creates and updates the Makefiles itself - in this setup, the dependencies (while not perfect, because there are a few bugs in CDT in this respect) should be managed well enough so that it won't rebuild the entire project just because one file changed.
On the other hand, if you imported an existing project via the menu File | New | Makefile Project with Existing Code (which I didn't previously mention), then you would have had to copy the Makefile from the existing project manually, as CDT doesn't copy it for you, or you would have had to manually create a Makefile.
As I mentioned previously, if you posted your Makefile (feel free to 'sanitise' it by removing any personal information), we might be able to determine why it's rebuilding all files when you've only updated one of them.
I would have posted this as a comment reply to your last comment, @davidgrandson, but apparently there's a fairly short limit on the length of these.
