Unless the MinW32 version of G++ is known to be fully link-compatible with MS Visual C++ (Visual Studio, or whatever), you have a big problem. This is a generic problem with the C++ libraries provided with CSDK - if you don't use the same C++ compiler that the library was compiled with, you run into problems. It most frequently occurs on Linux - when the version og GCC/G++ changes from say 3.3 to 3.4 - but you are likely to be running into the Windows analogue of this problem. -- Jonathan Leffler #include <disclaimer.h> Email: jleffler@earthlink.net, jleffler@us.ibm.com Guardian of DBD::Informix v2005.02 -- http://dbi.perl.org/
