I'm trying to compile the message pack (http://msgpack.org/) example code and keep getting these errors which I can't get to the bottom of:

And here is the code:
#include <msgpack/rpc/server.h>
class myserver : public msgpack::rpc::server::base {
public:
void add(msgpack::rpc::request req, int a1, int a2)
{
req.result(a1 + a2);
}
public:
void dispatch(msgpack::rpc::request req)
try {
std::string method;
req.method().convert(&method);
if(method == "add") {
msgpack::type::tuple<int, int> params;
req.params().convert(¶ms);
add(req, params.get<0>(), params.get<1>());
} else {
req.error(msgpack::rpc::NO_METHOD_ERROR);
}
} catch (msgpack::type_error& e) {
req.error(msgpack::rpc::ARGUMENT_ERROR);
return;
} catch (std::exception& e) {
req.error(std::string(e.what()));
return;
}
};
int main(void)
{
myserver svr;
svr.instance.listen("127.0.0.1", 80800);
svr.instance.run(4); // run 4 threads
return 0;
}
If anyone has any ideas, it would be greatly appreciated.
Many thanks in advance,
You need -lmsgpack-rpc
.
[Side note: 80800
is not a valid port.]
