Justin Ross updated QPID-1780:
------------------------------
Assignee: Gordon Sim
> Remove boost dependencies from C++ client API
> ---------------------------------------------
>
> Key: QPID-1780
> URL: https://issues.apache.org/jira/browse/QPID-1780
> Project: Qpid
> Issue Type: Bug
> Components: C++ Client
> Affects Versions: M4
> Reporter: Steve Huston
> Assignee: Gordon Sim
> Fix For: 0.8
>
>
> Currently there is a dependency on Boost headers being present when building
> a Qpid client application. I believe that Qpid client programmers should not
> have to be exposed to Boost just for building Qpid applications. It's a Bad
> Idea to impose a requirement such as this on all users - Boost is a
> supporting artifact of the implementation and shouldn't be a requirement for
> users.
> More pointedly, it could cause version skew on Windows installed kits. Unlike
> on RHEL, Windows doesn't offer Boost packages as part of the vendor-supplied
> OS kit. So, Windows users needing Boost must get their kit somewhere else.
> This makes it impossible to predict what version of Boost will (or won't) be
> on a user's system. To take care of this, the Windows installable kit is
> currently including the needed Boost DLLs that the kit is built against
> within the install. This removes the need to have Boost installed by the user
> prior to installing/using Qpid and isolates Qpid's binaries from whatever
> Boost version is present if there is one. This is a Good Thing except that
> when trying to build a client app (such as the Qpid examples) Boost ends up
> getting pulled in from the client API at build time. This is bad because the
> user now needs to go install Boost. If it's not the same version that the
> installed kit was built against, there's a chance that object sizes, methods,
> etc. will differ between what Qpid was built with and what the user installed.
> The case that brought this up immediately is that qpid/SessionId.h derives
> from boost::totally_ordered1<SessionId>. Since
> qpid/client/Session_Base_0_10.h defines a method which returns a SessionId by
> value, it needs to pull in SessionId.h which yields a compile error if Boost
> is not available.
