Linker Tools Warning LNK4098
defaultlib "library" conflicts with use of other libs; use /NODEFAULTLIB:library
You are trying to link with incompatible libraries.
Important The run-time libraries now contain directives to prevent mixing different types. You’ll receive this warning if you try to use different types or debug and non-debug versions of the run-time library in the same program. For example, if you compiled one file to use one kind of run-time library and another file to use another kind (for example, single-threaded versus multithreaded) and tried to link them, you’ll get this warning. You should compile all source files to use the same run-time library. See the Use Run-Time Library (MD, /ML, /MT, /LD) compiler options for more information.
You can use the linker’s /VERBOSE:LIB switch to determine which libraries the linker is searching. If you receive LNK4098 and want to create an executable file that uses, for example, the single-threaded, non-debug run-time libraries, use the /VERBOSE:LIB option to find out which libraries the linker is searching. The linker should print LIBC.LIB and not LIBCMT.LIB, MSVCRT.LIB, LIBCD.LIB, LIBCMTD.LIB, or MSVCRTD.LIB as the libraries searched. You can tell the linker to ignore the the incorrect run-time libraries by typing the incorrect libraries in the Ignore Libraries text box on the Link tab of the Settings dialog box in Developer’s Studio or by using the /NODEFAULTLIB:library option with LINK for each library you want to ignore. See the Ignore Libraries (/NODEFAULTLIB) linker option for more information.
The table below shows which libraries should be ignored depending on which run-time library you want to use.
To use this run-time library Ignore these libraries Single-threaded (libc.lib) libcmt.lib, msvcrt.lib, libcd.lib, libcmtd.lib, msvcrtd.lib Multithreaded (libcmt.lib) libc.lib, msvcrt.lib, libcd.lib, libcmtd.lib, msvcrtd.lib Multithreaded using DLL (msvcrt.lib) libc.lib, libcmt.lib, libcd.lib, libcmtd.lib, msvcrtd.lib Debug Single-threaded (libcd.lib) libc.lib, libcmt.lib, msvcrt.lib, libcmtd.lib, msvcrtd.lib Debug Multithreaded (libcmtd.lib) libc.lib, libcmt.lib, msvcrt.lib, libcd.lib, msvcrtd.lib Debug Multithreaded using DLL (msvcrtd.lib) libc.lib, libcmt.lib, msvcrt.lib, libcd.lib, libcmtd.lib
For example, if you received this warning and you want to create an executable file that uses the non-debug, single-threaded version of the run-time libraries, you could use the following options with the linker:
/NODEFAULTLIB:libcmt.lib /NODEFAULTLIB:msvcrt.lib/NODEFAULTLIB:libcd.lib /NODEFAULTLIB:libcmtd.lib/NODEFAULTLIB:msvcrtd.lib위의 에러는 사용하는 RUN-TIME 라이브러리가 일치하지 않을때 발생한다.즉, libGeneral.lib는 debug single threaded로 빌드하고 libGeneral.lib를 사용하는프로젝트는 다른 library(debug multithreaded)를 사용했을 경우 발생한다.서로 같은 형태의 라이브러리를 사용하도록 일치해줘야 한다.[출처] Linker Tools Warning LNK4098|작성자 ileksiah
