This usually happens if scons uses multiple cpu cores.
Either using a single core or just re-running the compile should do the trick.

Yes, We are facing the same issue here. The documentation provided is 
absolutely inadequate. I have also tried building with parallel disabled. Build 
it always hits the same issue. Any documentation whatsoever would be 
appreciated.

Hi All,

I am trying to set-up OpenContrail on Centos7. I am following the link :

https://github.com/michaelhenkel/opencontrail-centos-build

, but I am stuck with the following error during the build:

Install file: "controller/src/config/api-server/doc/source/conf.py" as 
"build/debug/config/api-server/doc/conf.py"
tools/generateds/generateDS.py -f -o

RPM build errors:
    Bad exit status from /var/tmp/rpm-tmp.5o4BfE (%install)



The build is failing for OpenContrail and I am unable to proceed forward. It 
comes with some scons error stuck due to dependency cycle although I have run 
all the scripts and gone through all the steps mentioned for downloading 
dependency packages for CentOS.

Thanks
Razi Ahmed
