Re: Turning warning into errors

[Duane Griffin]

Hi Sébastien,

I've not heard of that tool, but it sounds useful.

Unfortunately we now use cmake internally, but a while ago I wrote
some GNU makefile code to perform some checks like this for our rather
complex GNU make-based build system of the time. See the attached
file; it should still work and the undefined variables test is
hopefully relatively straight-forward and self-explanatory. You will
obviously need to adjust the targets in the check_undefined_vars
recipe as may be appropriate for your project. Note also the self-test
code, which should verify that the check actually works.

It also does several other checks which are probably not relevant to
you, but which I can explain if you are interested. Otherwise just
delete all the code unrelated to check_undefined_vars.

Cheers,
Duane.
