windows下rabbitmq-c编译（带openssl、无需MinGW）

因为项目原因，需要使用到rabbitmq的c客户端库。首先，参见上一篇windows下openssl编译，如果已经使用cmake编译过了，则先delete cache（File-Delete Cache），否则原来的cmake缓存都在了，将仍然会出现原来的错误。

依次点击configire、generate，可以生成vs sln。如下：

最后使用VS即可生成rabbitmq.4.dll，如下：

测试自带的例子：

D:\RabbitMQ Server\rabbitmq_server-3.6.5\sbin>cd /d D:\rabbitmq-c-0.8.0-build\examples\Debug

D:\rabbitmq-c-0.8.0-build\examples\Debug>amqp_listen localhost 5672 amq.direct test
Delivery 1, exchange amq.direct routingkey test
Content-type: text/plain
----
00000000: 68 65 6C 6C 6F 20 77 6F : 72 6C 64                 hello world
0000000B:
Delivery 2, exchange amq.direct routingkey test
Content-type: text/plain
----
00000000: 68 65 6C 6C 6F 20 77 6F : 72 6C 64                 hello world
0000000B:
Delivery 3, exchange amq.direct routingkey test
Content-type: text/plain
----
00000000: 68 65 6C 6C 6F 20 77 6F : 72 6C 64                 hello world
0000000B:
Delivery 4, exchange amq.direct routingkey test

新开一个窗口，执行如下：

D:\RabbitMQ Server\rabbitmq_server-3.6.5\sbin>cd /d D:\rabbitmq-c-0.8.0-build\examples\Debug

D:\rabbitmq-c-0.8.0-build\examples\Debug>amqp_sendstring localhost 5672 amq.direct test "hello world"

D:\rabbitmq-c-0.8.0-build\examples\Debug>amqp_sendstring localhost 5672 amq.direct test "hello world"

D:\rabbitmq-c-0.8.0-build\examples\Debug>amqp_sendstring localhost 5672 amq.direct test "hello world"

D:\rabbitmq-c-0.8.0-build\examples\Debug>amqp_sendstring localhost 5672 amq.direct test "hello world"

D:\rabbitmq-c-0.8.0-build\examples\Debug>amqp_sendstring localhost 5672 amq.direct test "hello world"

D:\rabbitmq-c-0.8.0-build\examples\Debug>amqp_sendstring localhost 5672 amq.direct test "hello world"

D:\rabbitmq-c-0.8.0-build\examples\Debug>amqp_sendstring localhost 5672 amq.direct test "hello world"

需要注意的是，librabbitmq的channel不是线程安全的，因此需要应用自行保证线程安全性，如下所述：

Threading

You cannot share a socket, an amqp_connection_state_t, or a channel between threads using librabbitmq. The librabbitmqlibrary is built with event-driven, single-threaded applications in mind, and does not yet cater to any of the requirements of pthreaded applications.

Your applications instead should open an AMQP connection (and an associated socket, of course) per thread. If your program needs to access an AMQP connection or any of its channels from more than one thread, it is entirely responsible for designing and implementing an appropriate locking scheme. It will generally be much simpler to have a connection exclusive to each thread that needs AMQP service.
