鲜花过多!
我一直在使用Visual Studio 2010开发静态链接的应用程序(嗯，它是跨平台的，但这只是Windows问题)。
在为Debug配置设置链接方面，我遇到的问题很少，因此我没想到很难更改它以创建Release配置，但是经过一个下午的工作，它仍然让我望而却步。尝试为NODEFAULTLIB设置各种值会导致“无法解析的外部符号”错误或“已定义”错误，有时还会同时出现。
从我的笔记中，我尝试过NODEFAULTLIB-LIBCMT，MSVCRT，MSVCPRT或根本不尝试，每次都具有不同的结果(有关详细信息，请参见下文)。
现在，我的Debug配置使用/NODEFAULTLIB:MSVCRTD/NODEFAULTLIB:MSVCPRTD并且可以正常工作，因此您认为/NODEFAULTLIB:MSVCRT/NODEFAULTLIB:MSVCPRT适用于Release配置。而且事实并非如此，这对我来说是个危险信号...
我正在与其他几个库建立链接-我非常谨慎地系统地确保从Debug到Release时它们被视为完全相同，但是可以想象这是一个问题，如果可以的话，如何系统地对其进行跟踪？
感谢您的宝贵时间!
在“链接器/命令行”属性页中，“所有选项”为:
/OUT:".\Release\SlowGold 8.exe" /NOLOGO "kernel32.lib" "user32.lib" "gdi32.lib" "winspool.lib" "comdlg32.lib" "advapi32.lib" "shell32.lib" "ole32.lib" "oleaut32.lib" "uuid.lib" "odbc32.lib" "odbccp32.lib" /MANIFEST /ManifestFile:".\Release\SlowGold 8.exe.intermediate.manifest" /ALLOWISOLATION /MANIFESTUAC:"level='asInvoker' uiAccess='false'" /PDB:".\Release\SlowGold 8.pdb" /SUBSYSTEM:WINDOWS /OPT:REF /OPT:ICF /PGD:"C:\development\rec-vs\rec\projects\slow\Builds\VisualStudio2010\Release\SlowGold 8.pgd" /LTCG /TLBID:1 /DYNAMICBASE /NXCOMPAT /MACHINE:X86 /ERRORREPORT:QUEUE
其他选项是:
/LIBPATH:..\\..\\..\\..\\externals\\rubberband\\win32\\ipp\\common ippacemerged.lib ippacmerged.lib ippcorel.lib ippsemerged.lib ippsmerged.lib ippsremerged.lib ippsrmerged.lib /LIBPATH:..\\..\\..\\..\\externals\\rubberband\\win32\\ipp\\release\\static rubberband-library.lib /LIBPATH:..\\..\\..\\..\\..\\glog\\Release libglog_static.lib /LIBPATH:..\\..\\..\\..\\..\\mpg123\\ports\\MSVC++\\2008\\Release libmpg123.lib /LIBPATH:..\\..\\..\\..\\..\\protobuf\\vsprojects\\Release libprotobuf.lib
这是各种/NODEFAULTLIB:值的一些错误消息。
迄今为止最好的:/NODEFAULTLIB:LIBCMT

最佳答案
汉斯·帕桑特(Hans Passant)在对我的问题的评论中向我提供了解决方案的关键!如果他回来并用他们作为答案，我会抹掉它，并把他归功于...
如预期的那样，其中一个第三方库在发行版中未设置为/MT(但在调试中为/MTd)-更改该标志可使它全部正常工作。
您可以在“属性”-“C/C++”-“代码生成”-“运行时库”中找到该选项。
