Try setting your path so that it isn't found before you run cmake. (1.4 seems odd though as it is so old) Andrew

Re: SASL
Hi Kai, As Gordon noted, proton can be used in different ways. In the case where it is used purely as an AMQP protocol engine with e.g TLS being provided by the external IO being used with it, getting the Principal would currently fall to that code rather than proton. That is how proton-j currently sees most of its usage (or at least, the usage I'm actually familiar with). The SASL/TLS related API's in proton-c have seen major rework since earlier releases, but the equivalents in proton-j have not and now differ substantially. I dont see an equivalent of the APIs Gordon referenced below, however as above its likely those may not apply in the particular usage context anyway when it comes to proton-j. I don't think there is much in the way of examples in this area I'm afraid other than the code of components using it (e.g the ActiveMQ brokers, or the Qpid JMS client).

Re: SASL
Thanks for your replies, Gordon. I didn't explicitly mention that I was interested in accessing the Principal from Java but you seem to have guessed that already :-) However, the question is still open, right?
