mongo-cxx-driver 库构建但持久的链接和调试问题答案

【问题标题】：mongo-cxx-driver library builds but persistent linking and debug issuesmongo-cxx-driver 库构建但持久的链接和调试问题
【发布时间】：2016-10-11 16:38:00
【问题描述】：

我正在尝试构建 mongo-cxx-driver 以在带有 Visual Studio 2015 的 Windows 10 上与 Cinder 一起使用。Cinder 使用 Boost 1.58，因此我针对他们包含的 Boost 版本构建了驱动程序。

我尝试完全按照 github 上描述的说明进行操作，但我得到的最终库和 dll 似乎存在问题。我希望有人帮助我调试我的编译出错的地方！

这就是我所做的，镜像官方说明here

步骤 1

我按照here 的说明安装了 MongoDB C 驱动程序。只需在 Windows 构建说明下复制/粘贴 CMake 调用即可完美运行。

第二步

由于我使用的是 Windows 和 Visual Studio 2015，我应该为 Polyfill 使用 Boost 选项。

第三步

我解压了从 github 下载的 mongo-cxx-driver-3.0.2；然后我进入 mongo-cxx-driver-r3.0.2\mongo-cxx-driver-r3.0.2 并运行 CMake：

cmake -G "Visual Studio 14 2015 Win64" -DCMAKE_INSTALL_PREFIX=C:\mongo-cxx-driver -DLIBBSON_DIR=C:\mongo-c-driver -DBoost_INCLUDE_DIR=C:\Cinder\include\ -DLIBMONGOC_DIR=C:\mongo-c-driver -DBSONCXX_POLY_USE_BOOST=1 ..

然后构建并安装项目：

msbuild.exe ./ALL_BUILD.vcxproj
msbuild.exe ./INSTALL.vcxproj

一切运行良好，我从 CMake 确认没有错误。万岁！

问题

在测试时，我尝试运行测试程序

#include <iostream>

#include <bsoncxx/builder/stream/document.hpp>
#include <bsoncxx/json.hpp>

#include <mongocxx/client.hpp>
#include <mongocxx/instance.hpp>

int main(int, char**) {
    std::printf("Starting mongo-cxx-driver test...\n");
    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;
    }
    std::printf("End of demo!\n");
}

如果我在 Debug 中运行它，那么它会在打印出数据库并显示“Debug Assertion Failed”消息后崩溃：

File: minkernel/crts/ucrt/src/appcrt/heap/debug_heap.cpp
Line: 980
Expression: __acrt_first_block == header

检查断点表明它在文件末尾的行上导致错误——可能在从行清理期间

std::cout << bsoncxx::to_json(doc) << std::endl

我的第一个怀疑是 .lib 文件和 .dll 可能是为发布而构建的——所以我在发布时构建了它。

我收到一个错误mongo_test.exe has triggered a breakpoint，断点位于bsoncxx.dll!bsoncxx::v_noabi::string::view_or_value::terminated() 深处。

在尝试调试时，我将插入行更改为：

mongocxx::result::insert_one result = collection.insert_one(document.view());

努力收集更多的调试信息。我惊讶地发现编译时不会出现 C2440 错误：

'initializing': cannot convert from 'boost::optional<mongocxx::v_noabi::result::insert_one>' to 'mongocxx::v_noabi::result::insert_one' mongo_test  C:\mongo_test\src\mongo_testApp.cpp 39

我怀疑问题可能在于我如何链接 Boost / std::experimental，但我尝试了几种不同的变体（禁用使用 boost 并使用 std::experimental 代替 polyfill），但是似乎没有创建一个工作库。或者可能与 Debug / Release 或 x64 与 x86 不匹配？

任何人都可以找出这个构建过程中的失误吗？

谢谢！

【问题讨论】：

你能试试 3.0.2 驱动和 Boost 1.59 吗？我们已经收到了使用这种组合在 MSVC 上取得成功的报告。
在使用 3.0.1 驱动程序和 Boost 1.58 时，MSVC 是否存在已知问题？
没有已知问题，但我们也没有专门测试过这种组合。
尝试 v3.0.2 驱动程序解决了基本的构建器问题——我没有遇到未链接对象的问题。但我仍然在调试模式下崩溃，在发布模式下出现断点。
我尝试运行测试，但构建失败了所有 3 个测试。我根据 README 使用 1.3.4 版本重建了 mongo-c-driver，但仍然失败。

【解决方案1】：

我知道这是一个老问题，但我今天遇到了这个问题，所以我会在这里将我的解决方案发布给任何可能感兴趣的人。它仅在调试模式下发生，当我将 /MD 更改为 /MDd 时错误停止。您可能需要重新编译 mongocxx 以匹配您的设置。
