QPID C++ Broker and QPID Proton C++ Example interoperability
problem
QPID/AMPQ noob here, but I could use some help.
I git-cloned the latest repos for qpid-cpp and qpid-proton. For each, I
successfully built and "sudo installed" with CMake/Make using default
configs.
As a test, I wanted to run qpidd and an example client & server from each
repo (cpp & proton).
The qpid-cpp broker (qpidd) seemed to work fine with the qpid-cpp examples
server & client.
However, when I tried to use the qpid-proton example server I had the
following results:
1. Running qpidd with a default qpidd.conf and then trying to execute
qpid-proton/bld/examples/cpp/server I get the following:
$ ./server
server connected to amqp://0.0.0.0:5672/examples
*amqp:connection:framing-error: AMQP header mismatch: Pre standard AMQP
connection ['AMQP\x01\x01\x00\x0a']*
so I seemed to recall reading somewhere that AMPQ 1.0 was not enabled by
default in qpidd (which seems odd to me), so I added "protocols=amqp1.0" to
my qpidd.conf and restarted the daemon.
2. Running qpidd with the modified qpidd.conf and then trying to execute
qpid-proton/bld/examples/cpp/server I get the following:
$ ./server
server connected to amqp://0.0.0.0:5672/examples
*amqp:connection:framing-error: AMQP header mismatch: Pre standard AMQP
connection ['AMQP\x01\x01\x00\x00']*
Seeing that the hex values changed I believe my change had an effect, but I
am left with a mystery as to why my qpid-proton based server cannot connect
to my qpid-cpp broker (qpidd).
*Can anyone shed some light or point me in a meaningful direction?*

Most welcome, thanks for giving the QPid project a try!

I am not sure of the proper etiquette here, but I wanted to say thanks to
Gordon.
Building the C++ qpidd with "-Damqp_force=true" did, in fact, solve my
problem.
Thank you.
John

The protocols option limits the available protocols offered. It doesn't
add them. As Adel points out, to have amqp 1.0 enabled, you need to have
the amqp.so module built (it depends on proton) and loaded (using
--module-dir or --load-module, or by having the module in the default
modules directory).
qpidd --help should show you the default module directory location and
you can check there whether amqp.so is available. If not, most likely
your broker was built without proton being installed. At present it is
treated as an optional dependency unless you set -Damqp_force=true (in
which case you'll get an error if proton can't be found).
We should probably start considering switching that round, so that
proton is required by default but if you don't want 1.0 you can
explicitly disable it.

Hello John,
A while ago, when I was testing with Qpid C++ broker, I encountered similar errors where I couldn't communicate using AMQP 1.0.
I solved it by launching qpidd with the following option "--load-module=amqp.so". Amqp.so is a library which is also built when you cmake/make Qpid C++ Broker. If you don't have it anywhere, make sure in the Cmake logs, you don't have something like "amqp disabled".
In the logs of the Qpid broker, you would see a log similar to "AMQP 1.0 support enabled" when the load-module is working.
Reference: http://qpid.apache.org/releases/qpid-cpp-0.34/cpp-broker/book/ch01.html#RASC-Slightlymorecomplexconfiguration
Regards,
Adel
