Hi Akila,
When we tried with the Apache Qpid Proton-C library we did the following
prerequisites.
# required dependencies
yum install gcc cmake libuuid-devel
# dependencies needed for ssl support
yum install openssl-devel
# dependencies needed for bindings
yum install swig python-devel ruby-devel php-devel perl-devel
yum install java-1.8.0-openjdk-devel
yum install epydoc
After that only we were able to build in the Ubuntu and run the python
client with proton support.I guess for every platform we need to do
the same and have to maintain different settings for different
platform.WDYT?
When it comes to the large number of instance, we need to do load
testing with the STOMP protocol.Thanks for pointing out this.
Thanks,
Gayan
