c++ - 如何在静态库中查找缺少的库依赖项（或根本原因）以及何时使用 externalproject 方法构建 cmake 目标

问题描述

我想为 jaeger 使用静态目标而不是链接到动态目标，静态目标编译得很好但是当我在我的代码库中使用它时，我看到未定义的引用错误：试过：

  1. Thrift 的动态/静态链接显式到 ceph（主代码库）：

  1. 尝试更改节俭静态库链接的顺序。
  2. 提示：由 Project 的 CMake 创建的静态目标可以与示例代码一起正常工作，但我不知道当它被构建为 ExternalProject(CMake) 时如何测试该目标，我可以以某种方式做到这一点吗？

on提示缺少定义，但我不知道为什么它没有包含在静态文件中，而当我链接到静态目标（例如代码（独立）而不是我想要链接的代码时，一切using **nm -uC libjaegertracing.a**正常. 我想知道如何知道并包含缺少的库/定义，以便在尝试将手动创建的目标与 libjaegertracing.a 一起使用时不会出现这些错误

构建良好的目标：[works] 用于添加依赖项：

function(add_lib_deps lib)
  target_include_directories(${lib} PUBLIC
    $<BUILD_INTERFACE:${CMAKE_CURRENT_SOURCE_DIR}/src>
    $<BUILD_INTERFACE:${CMAKE_CURRENT_BINARY_DIR}/src>)
  target_link_libraries(${lib} PUBLIC ${link_flags} ${LIBS})
  target_compile_options(${lib} PUBLIC ${cxx_flags})
endfunction()

添加源文件：

add_library(jaegertracing-static STATIC ${SRC})

与示例代码链接：

target_link_libraries(app PUBLIC ${JAEGERTRACING_LIB})

使用源代码[不起作用]

 add_library(jaeger-static STATIC IMPORTED)                                                                          
  add_dependencies(jaeger-static jaeger)                                                                              
  set(jaeger_INCLUDE_DIR ${jaeger_SOURCE_DIR}/src/)                                                                   
  set(jaeger_LIBRARY ${jaeger_BINARY_DIR}/lib/libjaegertracing.a)                                                     
  include_directories(jaeger_INCLUDE_DIR)                                                                             
  set_target_properties(jaeger-static PROPERTIES                                                                      
    INTERFACE_LINK_LIBRARIES "${jaeger_LIBRARY}"                                                                      
    IMPORTED_LINK_INTERFACE_LANGUAGES "CXX"                                                                           
    IMPORTED_LOCATION "${jaeger_LIBRARY}"                                                                             
    INTERFACE_INCLUDE_DIRECTORIES "${jaeger_INCLUDE_DIR}")

然后：

target_link_libraries() with primary target from my codebase
