the file isn't there.
This happens to random python packages compiled as native (sometimes
even for python-native itself), but (afaik) not for cross or target
packages (I'm pretty sure because of the different packaging applied).
So I digged a little into the code
classes/sstate.bbclass:sstate_install, which seems to create the
sysroot-component dir and the manifest.
There is a gap between the manifest creation (line 285) and the
hardlinking (line till 311).
Now my question is there any place where a file potentially could get
lost? - at first glance there shouldn't be one - I have to admit that I
don't fully understand all this subprocess magic in
lib/oe/path.py:copyhardlinktree.
What I do to fix the issue is reopening the manifest and double check
for missing files and remove them from the manifest, but this
feels wrong - so any advise is welcome...
Hope that someone more familiar with the topic could have a look.
Hi Konrad,
I'm not really familiar with that code but it's being run buy 1000s of
builder around the world so let's try to eliminate a few possibilities.
When did you start having this problem?
How often do you think it's happening: 1 in 3 builds, 1 in 10?
Tell us about your machine: OS,version, disk, CPUs, ram
Do you do anything special in your conf dir? Send local.conf perhaps.
Do you have any local bbappends or commits on top of poky or
in other layers?
Have you tried to simplify the build to eliminate problems
potentially caused by other layers?
Are you able to reproduce the problem on more than one build machine?
Are you able to reproduce the problem on a different Linux distro?
Are there other builds or users on the machine that may be causing
extra load?
../Randy
Thanks
Konrad
