Compiling muPDF lib in Eclipse “cannot unlink `NUL': Invalid argument Android NDK” Error

问题

I'm trying to compile the muPDF lib in Eclipse on Windows 7. I'm following these steps.

On this step

Build the native code libraries:
~/src/mupdf/platform/android $ ndk-build

I'm getting this error.

Qadir Hussain@GENETECH042 ~/mupdf/platform/android (master)
$ ndk-build

Also when I launch this command it creates a file NUL in my ..platform/android directory, the file has no extension and couldn't be deleted or renamed.
