Hi Jean,

I understand you use Visual C++ 2003 compiler.
But do you use your own project files and compile GDAL from the Visual
C++ IDE ?

If you use VC++ project files, please check if you use the same
compilation flags in the project file as specified in namek.opt file:

http://www.gdal.org/srctree/nmake.opt

as OPTFLAGS, especially if you use /MD flag.

Hmm, I'm confused.
Previously, you're saying you don't compile GDAL using makefile.vc but
here you're saying that you calls vsvars32.bat to configure command line
environment.
Please, explain exactly how do you build GDAL.

Cheers
