Greetings all,
I have a very strange problem with Gnu make. I'm not a make newbie by
any stretch of the imagination, but it has me completely stumped. I
apologise for the vagueness below but, for various reasons, I can't
really be more specific. I hope that the following is sufficient for
somebody to give me a clue.
I'm using make version 3.81 under Centos 5.5. We have a very convoluted
build system that I am no expert on (and definitely don't want to be!).
All of the following is reduced to the bare minimum to describe the
problem.
In a Makefile in a subdirectory of our top level directory, I have some
rules:
outfile: infile
cmd < infile > outfile
anotherFile: outfile
When I run make in the top level directory, it descends into this
directory and runs cmd to build outfile correctly. If I then manually
remove outfile and run the top-level make again, it says:
make: *** No rule to make target `outfile', needed by
`anotherFile'. Stop.
To fix it, I simply touch the subdirectory's Makefile and it will then
correctly build outfile again.
If anybody has any clues on this, it would be much appreciated.
Regards,
Graham
