Otavio Rodolfo Piske commented on PROTON-1036:
----------------------------------------------
I noticed that select_broker.cpp fails to compile if one of the following GCC
optimization levels is enabled: -Os, -O1, -O2, -O3. The reason for this seems
to be because the function ntohs is optimized out and replaced with a macro by
the compiler, therefore causing the following failure:
/home/opiske/code/cpp/rh/qpid-proton/examples/cpp/select_broker.cpp: In member
function ‘void broker::accept()’:
/home/opiske/code/cpp/rh/qpid-proton/examples/cpp/select_broker.cpp:139:30:
error: expected id-expression before ‘(’ token
<< ":" << ::ntohs(client_addr.sin_port)

> c++: engine API for integration with external IO frameworks

> Project: Qpid Proton
> Issue Type: Improvement
> Components: cpp-binding
> Affects Versions: 0.10
> Reporter: Alan Conway
> Assignee: Alan Conway
> Fix For: 0.11

>
> Provide a simple bytes-in/bytes-out per-connection engine to allow simple
> intergration of proton with external IO frameworks, where the goal is to have
> proton do *only* the AMQP decoding/encodiing/event handling and let the
> external framework take care of everything else: IO, timers etc.
