[Barrelfish-users] Problem building "hake" build system (now problem with make)

[Timothy Roscoe]

Dear Mark,

The trace definitions file should be generated very early on in the 
build process, since lots of parts of the system include it.

The first thing to try is start with a completely clean (i.e. empty) 
build directory, and run hake to create a new Makefile.  There are some 
limitations on dependency tracking that mean that an older, failed build 
(such as you might get by using a different version of ghc) make it hard 
to eliminate some bad dependencies.

If that doesn't work, there may be a bug in the trace Hakefile.  We're 
doing a release this afternoon that may fix it, but a good way to debug 
things (and, indeed, work around them) is to try:

$ make trace_definitions/trace_defs.h

  - in the build directory.   If this succeeds, you should then be able 
to use other make targets without problems.   As an aside, Hake 
generates a single Makefile with an explicit rule for every file, so you 
should be able to find the commands to build trace_defs.h.

Hope this helps,

  -- Mothy
