Visual Studio链接器警告LNK4098 [英] visual studio linker warning LNK4098

问题描述

我有一个dll项目，在发布配置中构建该项目时，出现以下警告:

I have a dll project in which, when in Release configuration I build the project, I get the following warning:

MSVCRT.lib(cinitexe.obj):警告 LNK4098:defaultlib'msvcrtd.lib' 与其他库的使用冲突；使用 /NODEFAULTLIB:库

MSVCRT.lib(cinitexe.obj) : warning LNK4098: defaultlib 'msvcrtd.lib' conflicts with use of other libs; use /NODEFAULTLIB:library

这只是一个警告，但我不知道是否应该考虑到这一点.

It's just a warning but I dunno if this should be taken into account.

对于我发现的东西，它们都是多线程库，普通版本和调试版本.我的dll使用多线程，并且可以调试它，尽管我使用boost:thread进行调试，所以如果需要此Windows特定库进行调试或发布版本，我真的不知道.

For what I've found out, they are both multithread libs, normal and debugging versions. My dll uses multithreading and I can debug it, although I use boost:thread for it, so I really dunno if I need this Windows specific libraries for debugging or Release building...

亲切的问候， 亚历克斯

好吧，我按照BuschnicK的建议进行了操作，并使用/VERBOSE:LIB链接器标志，发现我已在Debug配置中链接到这些库:

Well, I did as BuschnicK suggested and using the /VERBOSE:LIB linker flag I found out that I was linking to these libraries in Debug configuration:

boost_filesystem-vc100-mt-gd-1_44.lib: libboost_system-vc100-mt-gd-1_44.lib: libboost_thread-vc100-mt-gd-1_44.lib: libboost_date_time-vc100-mt-gd-1_44.lib:

boost_filesystem-vc100-mt-gd-1_44.lib: libboost_system-vc100-mt-gd-1_44.lib: libboost_thread-vc100-mt-gd-1_44.lib: libboost_date_time-vc100-mt-gd-1_44.lib:

我在Release config中具有相同的功能，主要是因为我没有明确地"指定.因此，我在Release中将其更改为此:

I had the same in Release config, mostly because I didn't specify then "explicitly". Thus, I changed them to this in Release:

boost_filesystem-vc100-mt-1_44.lib: libboost_system-vc100-mt-1_44.lib: libboost_thread-vc100-mt-1_44.lib: libboost_date_time-vc100-mt-1_44.lib:

boost_filesystem-vc100-mt-1_44.lib: libboost_system-vc100-mt-1_44.lib: libboost_thread-vc100-mt-1_44.lib: libboost_date_time-vc100-mt-1_44.lib:

这似乎可行，但我仍然收到第一个警告，直到我意识到我的Release配置中也有_DEBUG预处理程序定义，将其删除后，它现在可以正常工作了.

That seem to worked but I was still getting the first warning, til I realized I had the _DEBUG preprocessor definition in my Release config too, removed it and it's working sweet now.

感谢大家的帮助！

推荐答案

听起来您可以在同一版本中运行调试库和发行版编译库.

It sounds like you could be running a debug library and a release compiled library in the same build.

浏览项目选项，然后选择使用所使用的任何第三方库的调试版本.

Go through your project options and select to use the debug versions of any 3rd party libraries you use.
