Hi Wenzong,

We have seen some problems like this:

.../lib64/libpam.so: undefined reference to `audit_close'
......
The libaudit has been available and libpam build with it, after we run
another build with sstate-cache and w/o libaudit, the error occurs. The
solution in these cases is to use PACKAGECONFIG to lay out dependencies
on optional packages and make them explicit. We need to run an audit and
catch all of these issues.
A probable ways maybe:
1) Run world build to generate the sysroots as much as possible;
(See Ross's reply for a pointer to the new test-dependencies script)
That would be a good start point, I have run that script once, but looks
not any failure occurs.
I'll find a box and run it periodically.
Thanks

2) Run 'configure --help' on each package to spot all of the optional
dependencies, and convert them into PACKAGECONFIG specs/or any other
prompts.
Actually I have started along this line as well, putting the output of
configure --help into buildhistory so you can see the differences. I'm not
totally sure how useful it is at the moment and it will need some smooting out
to avoid known differences (paths etc.).
Cheers,
Paul
