Question

嘿伙计们，我希望这不是重复，但已经搜索过，并没有找到类似的问题。

我正在尝试使用visual studio在Windows 7 64bit上构建MongoDB C驱动程序，如http://mongoc.org/libmongoc/1.1.5/installing.html

中所述

cd mongo-c-driver-1.1.5\src\libbson
cmake -G "Visual Studio 10 Win64" "-DCMAKE_INSTALL_PREFIX=C:\mongo-c-driver"
msbuild.exe ALL_BUILD.vcxproj
msbuild.exe INSTALL.vcxproj

cd mongo-c-driver-1.1.5
cmake -G "Visual Studio 2010 Win64" "-DCMAKE_INSTALL_PREFIX=C:\mongo-c-driver" "-DBSON_ROOT_DIR=C:\mongo-c-driver"
msbuild.exe ALL_BUILD.vcxproj
msbuild.exe INSTALL.vcxproj

我做的完全相同，但是在为libmongoc构建ALL_BUILD.vcxproj时，我得到了未解析的外部符号，尝试了很多东西，但仍然达到了这个deadend。

Answer 1

修正了它，使用了

cmake -G "Visual Studio 14 2015 Win64" "-DENABLE_SSL=WINDOWS" "-DCMAKE_INSTALL_PREFIX=C:\mongo-c-driver" "-DBSON_ROOT_DIR=C:\mongo-c-driver"

而不是

cmake -G "Visual Studio 2010 Win64" "-DCMAKE_INSTALL_PREFIX=C:\mongo-c-driver" "-DBSON_ROOT_DIR=C:\mongo-c-driver"

默认情况下，mongoc将针对OpenSSL进行编译（如果可用）。在这种情况下，报告的OpenSSL版本似乎以某种方式被破坏，因为问题中的代码仅在检测到OpenSSL 1.0.2及更高版本时运行： https://github.com/mongodb/mongo-c-driver/blob/1.5.5/src/mongoc/mongoc-stream-tls-openssl.c#L641-L656 我很好奇你有哪些OpenSSL版本？

mongoc还支持其他TLS库，例如本机Windows安全通道。

在mongoc 2.0中（当我们可以更改ABI / API时），我们打算将默认值从OpenSSL更改为平台本机实现（Windows安全通道，macOS安全传输），而不是默认为OpenSSL。 LibreSSL（libtls）也受支持，将在找到时使用。

配置使用哪个TLS库，如上面的评论所述，将-DENABLE_SSL = WINDOWS传递给cmake（或DARWIN用于macOS安全传输）。
