Question

我正在尝试构建mongo-cxx-driver（最终），第一步是构建mongo-c-driver（需要libbson）。

我正在运行Windows 10并使用Visual Studio 2015作为我的编译器。我能够运行CMake并构建libbson就好了所有构建得很好的项目。现在，我有bson-static-1.0.lib内嵌mongo-c-driver/src/libbson/build/Debug/和mongo-c-driver/src/libbson/build/Release/的副本。这似乎一切都是正确的。

下一步是构建mongo-c-driver。我运行CMake并尝试创建Visual Studio解决方案，但得到了错误：

Could NOT find OpenSSL, try to set the path to OpenSSL root folder in the system variable OPENSSL_ROOT_DIR (missing:  OPENSSL_LIBRARIES OPENSSL_INCLUDE_DIR) 
Searching for sasl/sasl.h
  Not found (specify -DCMAKE_INCLUDE_PATH=C:/path/to/sasl/include for SASL support)
Searching for libsasl2
  Not found (specify -DCMAKE_LIBRARY_PATH=C:/path/to/sasl/lib for SASL support)
Current version (from VERSION_CURRENT file): 1.3.5
CMake Error: The following variables are used in this project, but they are set to NOTFOUND.
Please set them or make sure they are set and tested correctly in the CMake files:
BSON (ADVANCED)
    linked by target "mongoc_shared" in directory C:/Users/sdf/Downloads/mongo-c-driver-1.3.5
    linked by target "mongoc_static" in directory C:/Users/sdf/Downloads/mongo-c-driver-1.3.5

Configuring incomplete, errors occurred!
See also "C:/Users/sdf/Downloads/mongo-c-driver-1.3.5/build/CMakeFiles/CMakeOutput.log".

看起来变量BSON未设置为正确的值 - 它的值现在为BSON-NOTFOUND。有谁知道BSON的正确值是什么，以及它是否应该在编译libbson的过程中自动设置？

Answer 1

编译MongoDB c ++驱动程序的智能方法。使用 vcpkg

按照git上提到的说明下载vcpkg。 https://github.com/Microsoft/vcpkg

步骤1 C：\ vcpkg＆gt;。\ vcpkg搜索mongodb

步骤2 C：。\ vcpkg搜索mongodb安装mongo-cxx-driver

Stap 3 C：\ vcpkg＆gt;。\ vcpkg integration install

Answer 2

请仔细按照“在Windows上安装”说明进行操作：

https://api.mongodb.com/c/current/installing.html#building-windows

在构建libbson时，您似乎缺少设置CMAKE_INSTALL_PREFIX的部分，然后安装libbson并使用相同的CMAKE_INSTALL_PREFIX设置构建libmongoc。

Answer 3

首先，你需要在libbson sln中构建INSTALL项目（在管理模式下运行vs，因为它需要像linux一样创建lib文件夹）

然后定义BSON_INCLUDE_DIR以包含INSTALL项目创建的文件夹和BSON到您构建的lib文件，例如cmake中的 C：/ Program Files / libbson / lib / bson-static-1.0.lib （此BSON命名有问题，应重命名为BSON_LIB）

mongo-c-driver找不到libbson
