C++ 使用stringstream链接错误

我正在构建一个与OpenCV库静态链接的win32应用程序。在第一次尝试时，构建日志指示我忽略默认库msvcprtd.lib和libcmtd.lib，因为有很多链接错误，例如

"LIBCMTD.lib(sprintf.obj) : error LNK2005: _sprintf already defined in MSVCRTD.lib(MSVCR100D.dll)"

构建日志中的最后两句话是

1>LINK : warning LNK4098: defaultlib 'MSVCRTD' conflicts with use of other libs; use /NODEFAULTLIB:library
1>LINK : warning LNK4098: defaultlib 'LIBCMTD' conflicts with use of other libs; use /NODEFAULTLIB:library

排除这两个库后，我无法使用stringstream或cout，因为我遇到以下生成错误：

任何人都会遇到类似的错误？

每当Visual Studio开始抱怨

msvcrd.lib

和

LIBCMTD.lib

之间存在冲突时，您可以确定您正在链接在MicroFT运行时元素中链接不一致的项目

您提到您正在使用的OpenCV是静态链接的，我敢打赌您的项目是动态链接的。您应该设置解决方案文件，以便静态链接所有项目或动态链接所有项目。

听起来OpenCV静态库是针对不同的MSVS运行时创建的。您是否阅读发行说明？有关格式帮助，请参阅。
