[zeromq-dev] Using Strawhouse security pattern with ZeroMQ

[Check Peck]

I am trying to use Strawhouse security pattern in my zero-mq development. I
was following this wiki http://hintjens.com/blog:49 and when I try to run
below simple program to make sure I have everything installed, I got an
error -

#include <czmq.h>

int main (void) {
 zctx_t *ctx = zctx_new ();
 void *publisher = zsocket_new (ctx, ZMQ_PUB);
 zsocket_set_curve_server (publisher, true);
 puts ("Hello, Curve!");
 zctx_destroy (&ctx);
 *return* 0;
}
I tried to compile it like this -

gcc -o hello hello.c -lczmq -lzmq -lsodium

And the error I got -

/usr/bin/ld: warning: libzmq.so.4, needed by
/usr/local/lib/libczmq.so, may conflict with libzmq.so.3

Does anyone know what does this mean and what wrong I am doing?
