下載zmq：下載地址
解壓：tar -zxvf zeromq-4.1.6.tar.gz
編譯安裝
A.執行configure文件：./configure
出現錯誤：
configure: error: Package requirements (libsodium) were not met:
No package ‘libsodium’ found
解決方案：忽略這個庫
./configure --prefix=/home/ygy/zmq --without-libsodium（prefix中的路徑是zmq存放的目錄）
B.編譯：make
C.安裝：make install
三、樣例程序
（1）server端代碼：server.cpp
#include <stdio.h>
#include <unistd.h>
#include <string.h>
#include <assert.h>
#include <zmq.h>
int main (void)
{
// Socket to talk to clients
void *context = zmq_ctx_new ();
void *responder = zmq_socket (context, ZMQ_REP);
int rc = zmq_bind (responder, "tcp://*:5555");
assert (rc == 0);
while (1) {
char buffer [10];
zmq_recv (responder, buffer, 10, 0);
printf ("Received Hello\n");
sleep (1); // Do some 'work'
zmq_send (responder, "World", 5, 0);
}
return 0;
}
（2）client端代碼：client.cpp
#include <zmq.h>
#include <string.h>
#include <stdio.h>
#include <unistd.h>
int main (void)
{
printf ("Connecting to hello world server…\n");
void *context = zmq_ctx_new ();
void *requester = zmq_socket (context, ZMQ_REQ);
zmq_connect (requester, "tcp://localhost:5555");
int request_nbr;
for (request_nbr = 0; request_nbr != 10; request_nbr++) {
char buffer [10];
printf ("Sending Hello %d…\n", request_nbr);
zmq_send (requester, "Hello", 5, 0);
zmq_recv (requester, buffer, 10, 0);
printf ("Received World %d\n", request_nbr);
}
zmq_close (requester);
zmq_ctx_destroy (context);
return 0;
}
3）編譯
g++ server.cpp -o server -lzmq -I./include -L./lib
g++ client.cpp -o client -lzmq -I./include -L./lib
（4）運行程序
先運行server端：./server
出現錯誤：
./server: error while loading shared libraries: libzmq.so.5: cannot open shared object file: No such file or directory
解決方案：
找出libzmq.so所在路徑：sudo find ./ -depth -name “libzmq.so” -print
方案一：需要root權限，永久有效
將找到的路徑寫入ld.so.conf文件中：echo “填入所找到的路徑” >> /etc/ld.so.conf
重新加載配置文件：sudo ldconfig
