[xsd-users] DLL's VS 2010 and dllexport problems revisited

[Gordan Sikic]

Hi Boris,

thanks for your answer,

> It would be helpful to have more details on this.

It is the similar problem as explained in "2010-september" thread. There
are couple of mutually unrelated schemas, and every schema is compiled
into one dll. On many places in schemas, string enumerations are used,
and it turns out that resulting classes in c++ are inherited from
::xml_schema::string.

At the end, I have dependant dll that links all other dlls generated
from xsd schemas. Link stage of this dependant dll reports problem.

I have tried to compile minimal example, but it doesn't trigger the
problem, so I posted the question without it. Maybe you can (if
possible) send me example that is used in thread you refer to, so I can
check it as well?

I tried it (and followed it correctly), more than once. I've been
dealing with this problem for a couple of weeks now, and before posting
I made sure that all other possibilities are already explored and checked.

Maybe I was little bit vague in my explanation. When I wrote
automatically, I did not mean obligatory, just possibly, as some kind of
command line option (some kind of regex?).

I don't want to export types "per se", I don't need it. I want to export
member functions of generated classes only.

Ok, I understand that it is not route you are willing to take.
I would just like to ask why do you think it is a problem to have
hundreds of export macros within class, after all, it is automatically
generated code?


once more,
thanks for you answers,

cheers,
Gordan
