我尝试按照此链接中的教程:
http://hintjens.com/blog:49安装ZeroMQ并运行一个简单示例,如下所示:
#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;
}
但是,我收到此错误消息:
hello.c: In function ‘main’:
hello.c:4:5: error: unknown type name ‘zctx_t’
zctx_t *ctx = zctx_new ();
^
hello.c:4:19: warning: initialization makes pointer from integer without a cast [enabled by default]
zctx_t *ctx = zctx_new ();
^
hello.c:5:23: warning: initialization makes pointer from integer without a cast [enabled by default]
void *publisher = zsocket_new (ctx, ZMQ_PUB);
^
你能帮助我吗?
我正在使用Ubuntu 14,并且使用以下命令成功安装了ZeroMQ:
git clone git://github.com/jedisct1/libsodium.git
cd libsodium
./autogen.sh
./configure && make check
sudo make install
sudo ldconfig
cd ..
git clone git://github.com/zeromq/libzmq.git
cd libzmq
./autogen.sh
./configure && make check
sudo make install
sudo ldconfig
cd ..
git clone git://github.com/zeromq/czmq.git
cd czmq
./autogen.sh
./configure && make check
sudo make install
sudo ldconfig
cd ..
最佳答案 此代码使用CZMQ API v2,它已在v3中已弃用,在v4中已被删除(
https://github.com/zeromq/czmq/releases/tag/v4.0.0).使用v4的等效代码将是:
#include <czmq.h>
int main (void) {
zsock_t *publisher = zsock_new (ZMQ_PUB);
zsock_set_curve_server (publisher, true);
puts ("Hello, Curve!");
zsock_destroy (&publisher);
return 0;
}
您可以在https://github.com/zeromq/czmq/tree/master/examples/security找到所有样品的现代化版本.
