For the thorough testing that test-dependencies does you could argue that
entirely wiping tmpdir ensures that the builds are done from clean.

 2) Is there any overhead for subsequent builds from wiping the sysroots?

Only the overhead of extracting from sstate to repopulate the sysroot.

Thanks for the tips! I have two questions:

 1) Why does test-dependencies.sh remove TMPDIR instead of just wiping the
sysroots?

 2) Is there any overhead for subsequent builds from wiping the sysroots?
Guessing there shouldn't be, but better check.

Thanks,
Ulf

[yocto] Detecting missing build dependencies

2016-01-27 Thread Ulf Magnusson 
Hello,

If a recipe has a missing build dependency that the sysroot just
happens to contain anyway from an earlier build, then the build will
succeed only to fail later when the sysroot no longer has the build
dependency. We want to avoid that, so we're looking for ways to
automatically check for unspecified build dependencies.

The only method I know of at the moment is to remove or rename tmp/ so
that the build uses a fresh sysroot and then trying to rebuild the
recipe. Is there something nicer? I think I remember reading about a
script for testing for missing build dependencies, but I might be
misremembering.

Cheers,
Ulf

See openembedded-core/scripts/test-dependencies.sh but it basically
automates rebuilding recipes after removing TMPDIR, but also it detects
autodetected dependencies.

You're thinking of scripts/test-dependencies.sh.

Personally I just use wipe-sysroot (faster than deleting tmp) and
buildhistory-diff to verify build dependencies.
