C++使用RabbitMQ类库做客户端与RabbitMQ Server通讯，生成C++可调用的rabbimq.*.dll的过程

Step：

1. download the latest rabbitmq-c via: https://github.com/alanxz/rabbitmq-c
2. follow the document, download the cmake tool, make sure the right version of cmake. https://cmake.org/
3. install the C compiler, if developed by VS2012, so set MSVC110=VS2012
4. convert rabbitmq-c to C++ project via cmake command
   1. create "build" folder to rabbitmq-c root folder, then new bat file with below comman:

      REM -- create and put into /rabbitmq-c-0.9.0/build folder, then run the bat
      REM -- -DENABLE_SSL_SUPPORT=OFF disable SSL feature, otherwise will occur ssl error
      REM -- -G "Visual Studio 11 2012" , set the build environment
      cmake .. -DENABLE_SSL_SUPPORT=OFF -G "Visual Studio 11 2012"
      pause

       

5. open the C++ project generate in step 4, then build rabbitmq project with Release version
6. rename the rabbitmq.*.dll to rabbitmq.1.dll, then replace to the target folder

 

Troubleshooting:

1. "Could NOT find OpenSSL, try to set the path to OpenSSL root folder in the system variable OPENSSL_ROOT_DIR (missing: OPENSSL_CRYPTO_LIBRARY) (found suitable version "0.9.8h", minimum required is "0.9.8")"
   1. Solution1: add OPENSSL_ROOT_DIR command to bat file: -DOPENSSL_ROOT_DIR="C:\Users\zhengs\Downloads\openssl-0.9.8k_WIN32" https://stackoverflow.com/questions/16248775/cmake-not-able-to-find-openssl-library
   2. Solution2: Disable SSL suppport, add  "-DENABLE_SSL_SUPPORT=OFF" to command. https://github.com/conetix/librabbitmq
