Subject Build issues: Thermos executor not working
Date Tue, 17 Feb 2015 09:06:50 GMT
Hi everyone,

we try to build the latest Aurora git version on a Debian 7 host. Unfortunately, the resulting
executor seems to be broken, as it fails to start with the following message:

WARNING: Logging before InitGoogleLogging() is written to STDERR

I have attached the pants build log. It seems like pants is pulling in a wrong protobuf version
(protobuf-3.0.0_alpha_1 instead of protobuf 2.6.1). 

The issue can even be simulated locally:
* pip install mesos.interface with an old virtualenv 1.11 (including pip 1.5 and setuptools
2.0.2) pulls in protobuf-3.0.0-alpha-1
* pip install mesos.interface with the latest and greatest pip 6.0.8 and setuptools 12.2 pulls

How can this happen? Isn't the "build-support/virtualenv" script supposed to prevent that?
I also tried patching the setuptools_version in pants.ini, but it did not help.

Any ideas?

Best Regards,
