This simply means that not all of your libraries were built using the =
same runtime library options.  So you've got some module somewhere that =
is compiled to use the static LIBC library to find runtime functions, =
and another that is compiled to use the DLL version (MSVCRT).
=20
Have you tried following the compiler's instruction and using the =
/NODEFAULTLIBRARY switch?  This won't fix the warnings but it may avoid =
the error and let you link.

Subject: [Mapserver-users] Mapserver 3.7 linker error on Win32

Hi all,=20

I'm having problems with compiling MS3.7 under Win32. As far as I can =
tell, I have all the libraries built correctly and they are not =
conflicting versions. I am using GD2.0.7gif in order to get 24-bit =
rendering, and have enabled WFS and WMS support using libcurl.

Everything compiles fine, but at the link stage I get errors about a =
conflict between LIBC.lib and MSVCRT.lib (see below). I've seen messages =
before about multi-threaded versions of freetype causing this problem, =
but I am definitely linking to the single-threaded version. Are there =
any other libraries that could be causing such a problem?

I'm welcome to suggestions! I would ask if anyone has a pre-built =
executable, but a 3.7 exe with WMS, WFS, 24-bit, GDAL, OGR AND ORACLE =
SPATIAL support is probably asking a bit much..... ;-)

Cheers in advance,=20
