如何确保不忽略/ EDITANDCONTINUE指令

Question

当我尝试编辑并继续时,我收到此消息VSC15:

'file.cpp' in 'LIB.DLL' was not linked with Edit and Continue enabled. 
Ensure that /INCREMENTAL linking is enabled, and the /EDITANDCONTINUE directive is not ignored.

我已经确定/INCREMENTAL已启用但无法弄清楚第二部分.

编译器命令行:

/Yu"stdfx.h" /GS /analyze- /W3 /Gy /Zc:wchar_t /ZI /Gm- /Od /Fd".\Debug\vc140.pdb" /Zc:inline /fp:fast /D "x86" /D "WIN32" /D "_WINDOWS" /D "DEBUG" /D "_UNICODE" /D "UNICODE" /D "_WINDLL" /errorReport:none /WX- /Zc:forScope /RTC1 /GR /Gd /Oy- /MTd /Fa".\Debug\" /EHsc /Fo".\Debug\" /Fp".\Debug\LIB.pch"

链接器命令行:

/OUT:".\Debug\LIB.dll" /MANIFEST:NO /NXCOMPAT /PDB:".\Debug\LIB.pdb" /DYNAMICBASE /DEF:"EXPORT.DEF" /IMPLIB:".\Debug\LIB.lib" /DLL /MACHINE:X86 /NODEFAULTLIB:"libc.lib" /OPT:REF /SAFESEH /INCREMENTAL /PGD:".\Debug\LIB.pgd" /SUBSYSTEM:WINDOWS /MANIFESTUAC:"level='asInvoker' uiAccess='false'" /ManifestFile:".\Debug\LIB.dll.intermediate.manifest" /MAP /OPT:ICF

查看命令行:

编译器命令行:编辑和继续与/ Gm-实际上不兼容,它需要"启用最小重建"(/ Gm).

链接器命令行:/OPT:REF,/ SAFESEH,/ OPT:ICF都与编辑和继续不兼容,应该导致LNK4075.

如果您尝试清理构建LIB.dll,您应该看到警告,例如:

1>LINK : warning LNK4075: ignoring '/INCREMENTAL' due to '/OPT:REF' specification
1>ConsoleApplication1.obj : warning LNK4075: ignoring '/EDITANDCONTINUE' due to '/OPT:ICF' specification
