Linker warning LNK4006 problem...
Hi,
after long time I tried to build our libraries against XercesC on
Windows using MsDev .NET 2003 and I am getting over 13000 these
warnings when creating static library. I was checking all the project
settings but no success. Is there any way to get rid of them?
Thanks
Radovan
The warnings loook like:

Re: Linker warning LNK4006 problem...

Hi Alberto,
I took official XercesC zip distribution and compiled using MsDev
solution which BTW needed to be converted to the latest format. Once
having these XercesC libraries in place I created my new solution and
static library project for my sources and tried to build. I knew the
issues with mixing run-times from the past so I paid attention and set
them different for Debug and Release builds.
Looking at the MSDN I have found that these warnings may come due to
/Gy function level linking switch. I saw this is being used by
executable targets in XercesC examples but setting it off or on in my
static library project had no effect.
What are the recommended settings to build a client library using
XercesC lib files? I saw some preprocessor definitions to switch
dllexport or dllimport and I remember using these in our project
settings from the past with MsDev VC++ 6.0 now with MsDev .NET 2003
VC++ 7.1 I used them as well but not a big success. I get my library
built, it just takes a long time till MsDev dumps out all the warning
messages.
Cheers
Radovan

The error messages list xerces-c_2_6D.dll, but there is no
_dllimport/_dllexport in the function signature; did you modify the Xerces
project or header files?
If you are the sources from CVS (vs using the official 2.6 release) can you
try building Xerces as a static library (by selecting the "Static Build"
configuration)?
