安装并添加 eclipse 链接器 mongocxx bsoncxx 库后，尝试编译代码

#include <mongocxx/client.hpp>
#include <mongocxx/instance.hpp>
int main(int, char**) {
    mongocxx::instance inst{};
    mongocxx::client conn{mongocxx::uri{}};

    bsoncxx::builder::stream::document document{};

    auto collection = conn["testdb"]["testcollection"];
    document << "hello" << "world";

    collection.insert_one(document.view());
    auto cursor = collection.find({});

    for (auto&& doc : cursor) {
        std::cout << bsoncxx::to_json(doc) << std::endl;
    }
}

但它失败并出现错误：

g++ -O0 -g3 -Wall -c -fmessage-length=0 -std=c++11 -MMD -MP -MF"src/MongoCxx.d" -MT"src/MongoCxx.o" -o "src/MongoCxx.o" "../src

/MongoCxx.cpp"
../src/MongoCxx.cpp:8:9: warning: #pragma once in main file [enabled by default]
 #pragma once
         ^
../src/MongoCxx.cpp:13:31: fatal error: mongocxx/client.hpp: No such file or directory
src/subdir.mk:18: recipe for target 'src/MongoCxx.o' failed
 #include <mongocxx/client.hpp>
                           ^

也许我做错了什么在官方页面我按照说明如何安装 https://github.com/mongodb/mongo-cxx-driver/wiki/Quickstart-Guide-(New-Driver)

我使用 eclipse 和 OS OpenSuse
