Eclipse ignores build path? "make: *** No rule to make target"

edit

Hi,

I just started experimenting with OpenCV on Android a few dasy ago without problems. Today I wanted to install the Mac version of OpenCV, strangely now If I start Eclipse to continue my Android Project I got the error:

**** Clean-only build of configuration Default for project OpenCV Tutorial 1 - Camera Preview ****

/IOS Develop/Android Development/opencv/android-9/ndk-build clean 
usage: dirname path
make: /Users/vedtam/build/core/build-local.mk: No such file or directory
make: *** No rule to make target `/Users/vedtam/build/core/build-local.mk'.  Stop.

**** Build Finished ****

I have the NDK path configured in the project settings, but while building it returns to /User/vedtam..., folder. By the way the path the NDK Root path is highlighted in yellow in settings.

How to fix this?

Thanks
