静态链接 ActiveMQ-cpp

技术标签:
【中文标题】静态链接 ActiveMQ-cpp【英文标题】：Static linking ActiveMQ-cpp 【发布时间】：2018-04-25 10:54:35 【问题描述】：我正在创建一个 c++ 项目，我希望它在没有任何依赖关系的情况下以独立模式运行，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 和 libapr-1.a 在我的项目目录中找到
但我在链接过程中make main 之后遇到的错误是

还有更多..
我不知道如何修复这些错误
有什么建议吗？
【问题讨论】：
对于pthread 函数，请使用FindThreads 模块。
好的 pthread 错误消失了，其他的呢？
【参考方案1】：
我假设 apr 是 activemq 的依赖项。如果是这种情况，则需要切换apr和activemq的链接顺序。
链接器只会使用每个库一次。而当它处理 libactivemq-cpp.a 时，它看到它依赖于 apr，但 libapr-1.a 已经被处理了。
【讨论】：
感谢它指出我做错了什么的答案，我会发布完整的修复。【参考方案2】：发现我以错误的顺序执行target_link_libraries，正如Finn 指出的那样，我更改了库的顺序
