visual-studio - 如何确保/EDITANDCONTINUE指令不被忽略

Question

当我尝试在 VSC15 中编辑并继续时，收到此消息:

'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.

我已经确保 /INCRMENTAL 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:“编辑并继续”与/Gm- 并不真正兼容，它需要“启用最小重建”(/Gm)。

链接器命令行:/OPT:REF、/SAFESEH、/OPT:ICF 均与“编辑并继续”不兼容，并应导致 LNK4075。

如果您尝试全新构建 LIB.dll，您应该会看到如下警告:

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