zmq::recv_flags has not been declared #566

Hi all,

I am trying to run the first example in zguide on a RHEL7.9 machine (which I don't have sudo access to). Our school's IT has installed the latest versions of cppzmq-devel, czmq, czmq-devel and zeromq-devel (zeromq-4.1.4). However, I get the error mentioned in the title.

The problem seems to be the zmq.hpp file which doesn't include zmq::recv_flags or zmq::buffer etc. So what is happening? Should I ask them to build cppzmq from the source or am I missing something?

The latest cppzmq version is 4.8.1, what does it say in the zmq.hpp header?

maziar840 commented 2 years ago

There is no mention of version in zmq.hpp, but there is this in zmq.h:

/ Version macros for compile-time API version detection /

define ZMQ_VERSION_MAJOR 4

define ZMQ_VERSION_MINOR 1

define ZMQ_VERSION_PATCH 4

For those reaching this page in the future, currently the latest version of cppzmq in RHEL7 repo is 4.1.4 and RHEL8 is 4.4. I couldn't run the examples in zguide in any of those because of major API changes in zmq.hpp. Build the latest version from git.
