WAF hiding that build failed (Thomas in newbie mode...)

[Thomas Doerfler]

Hi all,

after a long time busy with other things, I am currently developing an
RTEMS application again, based on the current build system. Yesterday I
hit a strange error and, since this may happen to others, I want to
report it.

I rebuilt the latest libbsd using waf. Due to a version inconsistency
(my fault), the build failed and my screen showed the following:

Well, I thought, just another build output, no obvious error message, so
I proceeded with my application.

I fact, I missed the one important term "Build failed", which was about
100 lines above...

So, my question: is it possible to modify the build system so that the
summary "Build failed" is at the end of the output?

Kind regards,

Thomas.
