[heartshape21]

Describe the bug

https://zenoh-cpp.readthedocs.io/en/1.5.0/queryable.html
EVEN the example doesn't work

To reproduce

after I fix the compile issue, but also can not work

System info

[heartshape21]

this is my code
client.cpp
`#include "zenoh.hxx"
using namespace zenoh;

int main(int argc, char **argv) {
Config config = Config::create_default();
auto session = Session::open(std::move(config));

// Send a query and receive a stream providing replies.
// We will receive a FIFO buffer to store unprocessed replies (with size of 16).
auto replies = session.get(KeyExpr("demo/example/simple"), "", channels::FifoChannel(16));
while (true) {
std::cout << "recv" << std::endl;
auto res = replies.recv();
std::cout << "res: " << res.index() << std::endl;
Reply* reply = std::get_if(&res);
if (reply == nullptr) break;
if (reply->is_ok()) {
std::cout << "reply->is_ok()" << std::endl;
const Sample& sample = reply->get_ok();
std::cout << "Received ('" << sample.get_keyexpr().as_string_view() << "' : '"
<< sample.get_payload().as_string() << "')\n";
} else {
const ReplyError& error = reply->get_err();
std::cout << "Received an error :"
<< error.get_payload().as_string() << "\n";
}

}

std::cout << "No more replies" << std::endl;
}`

[DenisBiryukov91]

@heartshape21 Due to some reason z_liveliness_get is being called instead of normal z_get, could you please verify that you are linking against correct library version ?

[DenisBiryukov91]

The example was fixed here #591.
Otherwise I'm unable to reproduce the issue, please reopen the issue if it persists on your side.
