Please give an early review. The AMQP publish example works with broker example in qpid proton lib proton/c/examples/broker.

The build system is temporarily modified to link the proton lib as it doesn't build successfully as an object library owing to all the warnings enabled in the open62541 build system.

Hi, I am trying to evaluate .. but when i download the qpid-proton-cpp tar file, there are only 2 files. a. libqpid-proton-cpp.so.12.0.0 b. libqpid-proton-cpp.so.12

Seemed that libqpid-proton-cpp.a is missing. I am getting the following link errors:

... /usr/bin/ld: //usr/local/lib/libqpid-proton-cpp.so: undefined reference to pn_data_get_binary' /usr/bin/ld: //usr/local/lib/libqpid-proton-cpp.so: undefined reference topni_message_get_extra' /usr/bin/ld: //usr/local/lib/libqpid-proton-cpp.so: undefined reference to pn_condition_copy' /usr/bin/ld: //usr/local/lib/libqpid-proton-cpp.so: undefined reference topn_message_set_content_type' /usr/bin/ld: //usr/local/lib/libqpid-proton-cpp.so: undefined reference to pn_message_is_durable' /usr/bin/ld: //usr/local/lib/libqpid-proton-cpp.so: undefined reference topn_message_get_correlation_id' /usr/bin/ld: //usr/local/lib/libqpid-proton-cpp.so: undefined reference to `pn_ssl_domain_free' ...

Seemed that it is looking for proton lib functions..

During the installation process, i already did the following:

  1. sudo ldconfig -v
  2. update /etc/environment to include the path
  3. source /etc/environment and confirm that the libraries are loaded

The only thing i suspect is the missing <.a> file that normally comes together with the <.so> file ... can you advise? Thanks.

solve partially by indicating -Lqpid-proton-cpp in gcc the errors are reduced to :
