當使用mongo-cxx驅動程序構建C++項目時鏈接錯誤

Question

我目前正在開發一個C++應用程序，它需要使用mongo-cxx-driver來訪問MongoDB實例。我嘗試了幾種安裝方法，並且每次都遇到相同的鏈接器問題。

起初，我試圖安裝mongo-cxx-drivers和mongod-c-driver詳見這裏：https://mongodb.github.io/mongo-cxx-driver/mongocxx-v3/installation/

用我的CMake配置的以下部分，我是能夠得到自動完成的工作和我的IDE識別庫：

. . . 

set(CMAKE_CXX_STANDARD 17) 

set(BUILD_DIR "cmake-build-debug") 
set(BUILD_PATH "${CMAKE_SOURCE_DIR}/${BUILD_DIR}") 

find_package(libmongocxx REQUIRED) 
find_package(libbsoncxx REQUIRED) 

message("LIBMONGOCXX_INCLUDE_DIRS = ${LIBMONGOCXX_INCLUDE_DIRS}") 
message("LIBMONGOCXX_LIBRARIES = ${LIBMONGOCXX_LIBRARIES}") 

message("LIBBSONCXX_INCLUDE_DIRS = ${LIBBSONCXX_INCLUDE_DIRS}") 
message("LIBBSONCXX_LIBRARIES = ${LIBBSONCXX_LIBRARIES}") 

file(GLOB COMMON_LIBRARIES ${LIBMONGOCXX_LIBRARIES} ${LIBBSONCXX_LIBRARIES}) 

SET(APP_SOURCE source/App/main.cpp) 

SET(CMAKE_RUNTIME_OUTPUT_DIRECTORY ${BUILD_PATH}/App) 
add_executable(App ${APP_SOURCE}) 
target_include_directories(App PUBLIC ${LIBMONGOCXX_INCLUDE_DIRS}) 
target_include_directories(App PUBLIC ${LIBBSONCXX_INCLUDE_DIRS}) 

target_link_libraries(App ${COMMON_LIBRARIES}) 

. . . 

不幸的是在連接階段，我得到這些錯誤：

[100%] Linking CXX executable App/App 
    Undefined symbols for architecture x86_64: 
    "mongocxx::v_noabi::uri::uri(bsoncxx::v_noabi::string::view_or_value)", referenced from:

爲了以防萬一，我嘗試使用不同的c++17填充材料建造，不行。我也嘗試手動卸載mongo-cxx-driver和mongo-c-driver這次安裝通過自制軟件，但遇到了相同的錯誤。

在我的研究中，最關心的StackOverflow帖子是Using the mongodb cxx driver in a cmake c++ project，但沒有任何解決方案爲我工作。

Operating System: macOS Sierra 10.12.6

任何幫助或洞察力將不勝感激，請隨時問我澄清或補充，其中可能不清楚或遺漏的信息。

編輯：這裏是導致該錯誤代碼：

#include <cstdint> 
#include <iostream> 
#include <vector> 
#include <bsoncxx/json.hpp> 
#include <mongocxx/client.hpp> 
#include <mongocxx/instance.hpp> 
#include <mongocxx/uri.hpp> 
#include <mongocxx/stdx.hpp> 

using bsoncxx::builder::stream::close_array; 
using bsoncxx::builder::stream::close_document; 
using bsoncxx::builder::stream::document; 
using bsoncxx::builder::stream::finalize; 
using bsoncxx::builder::stream::open_array; 
using bsoncxx::builder::stream::open_document; 

mongocxx::instance instance{}; // This should be done only once. 
mongocxx::uri uri("mongodb://localhost:27017"); 
mongocxx::client client(uri); 

編輯：我繼續從頭開始創建一個簡單的項目，所有的步驟又去公正，以確保我沒有什麼都不感冒。儘管如此，仍然在同一條船上。

Answer 1

原來我正在使用CMake的GLOB錯誤。

改變

target_link_libraries(App ${COMMON_LIBRARIES}) 

到

target_link_libraries(App ${LIBMONGOCXX_LIBRARIES} ${LIBBSONCXX_LIBRARIES}) 

固定的問題。
