Hello John
I have looked up the Web site you mentioned

>From the first glance he did miss the step to create the VC++ "export"
library.
Why he did not realize it? The problem with the "export" library is
raised when one tries to build more then one DLL and those contain the
cross references.
For example, you want DLL to instantiate an object from another one or
you want the main executable to create some object from DLL or something
like this.
Many simple applications do fit in a single DLL and do not require that
step and it can be missed.
However for the more complex one as (I suspect) is yours one may not
miss that step.
I have surprised myself finding another Web page:
http://www.muenster.de/~naumana/rootmsvc.html
doesn't explain this matter either.
So the quick advice, to avoid a lengthy explanation, is to use either
ACLiC or the
%ROOTSYS%\test\Makefile.win32 makefile as a pattern. That Makefile is
not quite convenient since it builds many different executables and
DLL's at once. So you have to sort it out and disregard all rules to
build the various executables and leave Event.DLL rules only.
> Ack! I have successfully built in Linux, but in VC++ I'm getting lots
Yes this raises my suspicion; Linux (gcc) doesn't require any "export"
library to be build.
Probably Philippe's guess is not correct suggesting
"You are missing the linking with your own dictionaries".
In this case you may not have created executable on Linux either.
Hope this helps,
