I'm trying to add a new utility to the $(TOP)/ghc/utils folder. The utility has a make file, but I can't seem to get it to play nice with GHC's build system.  The error I receive is "No rule to make target...".

Here's a simple test environment that demonstrates the problem:

What am I not understanding?

I believe you need to add utils/testmake to the BUILD_SUBDIRS variable in the root ghc.mk.

That did the trick. I somehow stumbled upon https://ghc.haskell.org/trac/ghc/wiki/Attic/Building/BuildSystem/New, and was using that as a guide.  It looks like I missed reading https://ghc.haskell.org/trac/ghc/wiki/Building/Modifying, where BUILD_DIRS is documented.  My bad. Thanks for the quick response. Chris.
