[Buildbot-devel] Status of Multi-Project Support

[Mark Roddy]

Mark,
I'm in a similar situation.  What I've been doing is to have a
separate build for each project and each build checks out the required
dependencies as well as the project being tested.  This does have a
limitation though that if someone commits to project A and project B
depends on A, only the build for project A gets run.  We work around
this by having all our builds run 3 times a day, though we loose the
tracking of what commit broke everything.  Also, depending on your
build process, this might not be feasible.  I noticed you said that "
the output of one project is involved in the build of another".  In
our case each build checks out all the project dependencies which
isn't much of an issue for us most of our software is written in
Python which removes the compile phase.  I could see that if you had a
large set of c/c++ projects that it would consume a lot of resources
to duplicate the compile step for each project.
