Help with some makefile hackery

[Patrick Mahan]

Oy vey!

Good point!  Not something I had considered (but should have).  Is there
a way to propogate that status through the pipe?  I am using 'tee' so
that the master build (which invokes the top-level make) can also see
the make output.  But going back and reading the man page on 'sh' shows
me that on a pipline, the status is the status of the *last* command.

Maybe I should do this instead?

src-kernel: src-kernel-tools
	cd src; ./amd64-kernel.sh 2>&1 > build_amd64_kernel.log; \
		tail -f build_amd64_kernel.log

It is not too clear if the status is the last one in a compound command.

I will give that a try.

Thanks,

Patrick
