I have checked my target list, the list, which is created by the unpacking tool can be stored a file- or dirname
more than one, so the target list is not unique.
So I do before the return call in the emitter list(set(target)) for uniquifing my target list.

But I get a warning if I add my builder to the environment:
No dependency generated for file: <eg stdlib.h>

My emitter get's the filelist of an tgz file, wich stores *.c and *.h files, after that I push the list
to env.SharedLibrary. Scons compiles all *.c files and calls the linker, the DLL is build and
seems to be working, but I would like to remove the warning.

At the moment my emitter works like this:

*.tgz => unpack emitter list files in the archiv => list is pushed to SharedLibrary

the builder extract the files


If I write Scons code eg

env = Environment( tool=["default", "unpack"] )
env.SharedLibrary("testlib", Glob("src/*.c"))

the error is occured, if I change the the first line to

env = Environment( tool=["default"] )

no error is shown. So IMHO I have create an error in my builder code, does anybody send my
a helpfull tip, to search the error?

Thx

Phil
