静态链接ActiveMQ-cpp
Static linking ActiveMQ-cpp
我正在创建一个 c++ 项目，我希望它在独立模式下 运行 没有任何依赖关系，因为它将部署在多个服务器上。
这是我的 CMakeLists 文件：
project(CMS-test)
cmake_minimum_required(VERSION 2.6)
add_executable(main main.cpp)
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")
INCLUDE_DIRECTORIES(/usr/local/apr/include/apr-1)
INCLUDE_DIRECTORIES(/usr/local/include/activemq-cpp-3.9.4)
target_link_libraries(main ${CMAKE_SOURCE_DIR}/libapr-1.a)
target_link_libraries(main ${CMAKE_SOURCE_DIR}/libactivemq-cpp.a)
libactivemq-cpp.a and libapr-1.a are found in my project directory
但是我在链接期间 make main 之后遇到的错误是

还有更多..
我不知道如何解决这些错误
有什么建议吗？
我假设 apr 是 activemq 的依赖项。如果是这种情况，需要调换apr和activemq的link顺序。
linker 将只使用每个库一次。当它处理 libactivemq-cpp.a 时，它发现它依赖于 apr，但是 libapr-1.a 已经被处理了。
发现我以错误的顺序执行 target_link_libraries，正如 指出的那样，我更改了库的顺序

我不知道如何解决这些错误
有什么建议吗？
我假设 apr 是 activemq 的依赖项。如果是这种情况，需要调换apr和activemq的link顺序。
linker 将只使用每个库一次。当它处理 libactivemq-cpp.a 时，它发现它依赖于 apr，但是 libapr-1.a 已经被处理了。
发现我以错误的顺序执行 target_link_libraries，正如
完整的 CMakeLists 文件现在是
