722903 - Install OS packages on Jenkins to support building Sync Server

Status: RESOLVED INVALID

(mozilla.org Graveyard :: Server Operations, task)

Description

[Gregory Szorc [:gps]]

I'm trying to get the Sync Server Python code building on the public Jenkins server at ci.mozilla.org/. The project needs some OS packages installed to build. Unfortunately, these don't seem to be installed currently.

At this time, the build currently seems to be blocked on missing files for libevent. Please install the following packages:

  libevent libevent-devel

I anticipate multiple packages needing to be installed in the end. Please ping me after these are installed and we'll see what additional packages (if any) need to be installed.

I installed libevent, but libevent-devel conflicts with compat-libevent14, which is required for memcached.

Hmmm. It appears the Python gevent package requires libevent 2.x. I see memcached supports libevent 2.x, so from my perspective the ideal path would be to upgrade memcached. But, I don't want to ask for that unless I get buy-in from whoever is using memcached. Oh, dependency hell.

I could try working around this by compiling libevent 2.x as part of the local build.

Let me masticate on this.

I worked around the conflict by building libevent 2.x inside Jenkins and then reference that build from our project. Rest assured, I did not install libevent 2.x in system-wide location, so nobody should notice.

You can optionally remove the libevent package then mark this WONTFIX or WORKSFORME.
