Quoting from http://lists.samba.org/archive/distcc/2004q1/002160.html

There are (at least?) three reasons why this might be so:

  1) The parent make didn't realize that the child process it was
     invoking was actually a "make" program.  In this case, it won't
     allow the child to connect to the jobserver.  This is typically
     because the command to invoke the child uses "make" or similar
     rather than the correct $(MAKE).  See the docs on the "+" token to
     understand the algorithm GNU make uses to determine if the child is
     a sub-make or not.

Bye, Jörg.
