How do I find what is causing this warning from the Linker? If I use
/NODEFAULTLIB I get hundreds of undefined symbols.

LINK : warning LNK4098: defaultlib 'MSVCRT' conflicts with use of other
libs; use /NODEFAULTLIB:library

Here is the compiler options:

/Od /I "C:\DriverX4\Include" /I "..\ThreadLib" /AI "..\Utility\bin\Debug"

/D "_MBCS" /FD /EHsc /MDd /GS /Fo"Debug/" /Fd"Debug/vc70.pdb" /W3 /nologo /c
/Zi /clr /TP

Here is the linker options:

Here is the linker output with /VERBOSE:LIB

As you can see below, you are linking with both, the release as well
as the debug version of crt library. I am not sure which one you
really intended to use, but just remove msvcrtd.lib from the linker
input and you should be ok I think.

hth

I had msvcrtd.lib as an additional dependency because I was following the
procedure in the "Converting Managed Extensions for C++ Projects from Pure
Intermediate Language to Mixed Mode" document which I found by searching for
Warning LNK4243.

Now I have remove msvcrtd.lib from the additional dependencies list. I
still receive Warning LNK4098 on the debug build but not on the release
build. Maybe one of the commercial libraries I am using is causing the
problem. cbw32.lib is the Universal Library from Measurement Computing
which is used for talking to a Digital I/O card. There is only one version
of this library. mdxdrtld.lib is the DriverX library form Tetradyne which I
use for talking to how custom made ISA I/O card. DriverX comes with source
for the lib, so I have compiled the release & debug versions with VS 2003.
I also have winmm.lib in the Additional Dependencies list. Is there a debug
version of winmm?

Looks like I need to write test programs which use thes libraries one at a
time to see what happens.

Since this is a warning and only happens on the debug build, can I saftly
ignore it?

thanks

Bill

Looks like I lied in that last message.

I just recompiled the DriverX library mdxdrtld.lib and the warning
LNK4098 went away. Looks like it was compiled with VS 2002 and I am now
using VS 2003.
