Description Bogdan Alexandru Voiculescu 2016-01-14 08:51:32 UTC 
PAM is not enforced as a needed distro feature for core-image-minimal.


"WARNING: Building libpam but 'pam' isn't in DISTRO_FEATURES, PAM won't work correctly" instead of an error.


Examples:
 bitbake core-image-minimal

Comment 1 Joshua Lock 2016-01-14 08:57:36 UTC 
The bug here is not that pam isn't enforced as a distro feature, but that something is including pam as a DEPENDS (either implicit or explicit) without first checking whether pam is in DISTRO_FEATURES.

I'll take a look and see if I can figure out what component that is.
Comment 2 Bogdan Alexandru Voiculescu 2016-01-14 08:58:18 UTC 
Adding exact steps: 
1) git clone a fresh master repo
2) source environment 
3) (optionally - set SSTATE)
4) bitbake core-image-minimal 

- Results: at some time, 
"WARNING: Building libpam but 'pam' isn't in DISTRO_FEATURES, PAM won't work correctly" is displayed; this is not immediate (but is before compiling gcc) 

- Expected: image build without this warning
