问这样我就可以自己回答这个问题,为此损失了一天时间,并想省去其他人的麻烦。
设置:
- Windows(在Windows 10和Server 2019上都可以看到(
- Visual Studio(可在Visual Studio 2017和Visual Studio 2019上看到(
- cmake 3.19.0-rc1(截至本文的最新下载(
- 遵循上的说明https://docs.aws.amazon.com/sdk-for-cpp/v1/developer-guide/setup.html适用于从AWS C++SDK源代码构建的Windows。源代码标准构建和
vcpkg
备选方案都会发生这种情况。如果您尝试构建";第三方依赖性";在https://github.com/aws/aws-sdk-cpp手动
您可以尝试以下操作:
git clone https://github.com/aws/aws-sdk-cpp.git
cd aws-sdk-cpp
mkdir build
cd build
cmake ..
你收到来自cmake的投诉结束:

完全不明显,但问题似乎与"cmake 3.19.0-rc1";。更改为cmake 3.18.4绕过了这个问题。我不知道这是cmake问题还是sdk问题,或者我会在别人的github上发布,而不是stackoverflow。
我遇到了同样的问题,我发现Visual Studio 2019 16.9.1附带的CMake坏了(报告为3.19.20122902-MSVC_2
的版本(。
我更改了CMake的路径,指向Vcpkg使用的路径,即3.19.2
版本,现在它运行得很好。
因此,我认为该错误存在于Visual Studio附带的CMake中,并在3.19.2中修复。
