链接到VS中的静态0MQ库 [英] linking to a static 0MQ library in VS

问题描述

这可能是Visual Studio的问题，而不是其他任何问题...
我正在尝试使用VS10和ZeroMQ 2.2.0构建 0MQ C ++示例. 我下载了 Windows源文件，并尝试遵循

This may be a Visual Studio question more than anything else...
I'm trying to build a 0MQ C++ example using VS10 and ZeroMQ 2.2.0.
I downloaded the windows sources and tried to follow these instructions in order to build 0MQ statically. Specifically:

• 切换到发行版
• 对于解决方案中的所有7个项目:
  • 将General\Configuration Type设置为Static library (.lib)
  • 将C/C++\Code Generation\Runtime Library设置为Multi-threaded (/MT)
  • 将ZMQ_STATIC添加到C/C++\Preprocessor\Preprocessor Definitions
  • Switched to Release
  • For all 7 projects in the solution:
    • set General\Configuration Type to Static library (.lib)
    • set C/C++\Code Generation\Runtime Library to Multi-threaded (/MT)
    • added ZMQ_STATIC to C/C++\Preprocessor\Preprocessor Definitions

    此时，0MQ似乎构建良好.

    At this point 0MQ seems to build well.

    • 创建了一个空的控制台项目:
      • 切换为发布
      • 使用上面链接的示例添加了一个cpp文件
        • 将random更改为rand，将srandom更改为srand，并且将snprintf更改为_snprintf
        • Created an empty console project:
          • switched to Release
          • added a single cpp file with the example linked above
            • changed random to rand, srandom to srand and snprintf to _snprintf

            但是我仍然收到以下链接错误:

            However I still receive the following linking errors:

            1>zmqexp.obj : error LNK2001: unresolved external symbol __imp__zmq_bind
            1>zmqexp.obj : error LNK2001: unresolved external symbol __imp__zmq_close
            1>zmqexp.obj : error LNK2001: unresolved external symbol __imp__zmq_errno
            1>zmqexp.obj : error LNK2001: unresolved external symbol __imp__zmq_init
            1>zmqexp.obj : error LNK2001: unresolved external symbol __imp__zmq_msg_data
            1>zmqexp.obj : error LNK2001: unresolved external symbol __imp__zmq_strerror
            1>zmqexp.obj : error LNK2001: unresolved external symbol __imp__zmq_socket
            1>zmqexp.obj : error LNK2001: unresolved external symbol __imp__zmq_msg_init_size
            1>zmqexp.obj : error LNK2001: unresolved external symbol __imp__zmq_term
            1>zmqexp.obj : error LNK2001: unresolved external symbol __imp__zmq_msg_close
            1>zmqexp.obj : error LNK2001: unresolved external symbol __imp__zmq_send
            

            我错过了什么?

            推荐答案

            您也应该在空控制台项目"中将ZMQ_STATIC添加到C/C++\Preprocessor\Preprocessor Definitions.否则，在编译应用程序时，zmq.h中的ZMQ_EXPORT被定义为__declspec(dllimport)，因此，MSVC将查找__imp__zmq_*符号而不是zmq_*

            You should add ZMQ_STATIC to C/C++\Preprocessor\Preprocessor Definitions in your "empty console project" too. Otherwise, when you compile your application, ZMQ_EXPORT in zmq.h is defined as __declspec(dllimport), and as a result, MSVC looks for __imp__zmq_* symbols instead of zmq_*
