Eclipse CDT Does Not Exclude Explicitly Excluded Files

[Elkvis]

I'm having a problem with Eclipse Juno CDT, in which I instruct eclipse to exclude a source file from the build, but it simply ignores my exclusion. It continues to try to build the "excluded" files, and gives errors. I tried two different ways:

1. Right click on file -> Properties -> C++ Build -> Exclude Resource from Build -> OK

2. Right click on file -> Resource Configuration -> Exclude from Build... -> check all build configurations -> OK

I don't know what else I can try. I'm really frustrated with this, and I have had no luck finding any other methods of excluding files from the build in searching the web.

Am I missing something, or have I discovered a bug?

I'm probably going to annoy you, but are you sure you aren't trying to exclude a source file with definitions declared on a header file?

I have a subdirectory in my project - let's call it x for now - and x contains a subdirectory called backup. x/backup contains older versions of the files in x, but I don't want to build the files in x/backup because it produces linker multiple definition errors. I may have found a workaround. I found a reference to filters, but it just seems like a lot of hassle, and it makes no sense to me why the seemingly obvious method doesn't do what it claims to do.
