New subject: Boost serialization anddependencynightmares...

10 May 2005

      Hi Robert,

I've been looking into this further and found some
interesting behavior.  Don't know if this will help or not,
but here goes: 

* In linux I have my xyz.cpp file, several includes, the
archive include, then the export, like this:

#include    // should
always be after archive includes

After that I have:
BOOST_CLASS_EXPORT(Foo::Bar::MyClass);

using namespace Foo::Bar;

// the rest of the file.

This code plus the rest will compile, link, and run
properly in Linux using gcc 3.2.2.  (I can get more version
info if you need, kernel, glibc, etc.)

* In Windows Server 20003 with cl version 13.10.3077 I can
not compile.  I get the same error message I stated
earlier. 

Now the wierd part:

If I remove the
#include 

I cannot compile anymore with gcc, as expected.  There
error I get is this:
ISO C++ forbids declaration of `BOOST_CLASS_EXPORT' with no
type

In Windows not only does it compile, but it links and runs.
 'runs' meaning there is an .exe file but my serialization
test code still fails ;)

I dont know if these annoying details may help but I just
thought I'd share.

Hi Robert,
The EXPORT macros were initially inside a namespace,
interesting that it compiled and linked with gcc.
After fixing this I still have the same problem with
Microsofts compiler.  It complains about the same thing
as
I state below.  Is there some include file that I may be
missing?  I can send you some code if that helps.
Also where is the best place to call these macros?  At
the
moment they are at the top in the appropriate .cpp files.
Thanks,
-K

Just a guess, but are the EXPORT macros being used in
side a namespace?
They should be outside of any namespace.

is  exactly the same problem I am having:
boost 1.32, with VC7.1 I'm getting compiler errors in

Why would the 3 argument overload not be found?
Below are the (beginnings of the ) related compiler

Robert,
Thank you.  My project requires both linux and Win32
support.  When I use this macro in win32 environment
I
get
a compile time error.  It generates a fairly long
error
which I can send you but here is the first few lines
which
are possibly the most important.
Again it is fully compiling/linking/running in
Linux.

When I #ifdef the BOOST_CLASS_EXPORT(ClassName)
macros
I
compile/link/and run.  Of course base class
serialzation
is
disable for Win32 at the moment because of this.
Thanks for any help,

This is addressed with the alternative
BOOST_CLASS_EXPORT
method.  its
described in the serialization documentation.

Hi all,
I have a container class that has a vector which
contains
several other classes.   My container class has a
serialize
function that looks like this:
friend class boost::serialization::access;
template<class Archive> void serialize (Archive
&ar,
const
unsigned int version)
{
   // save/load base class information
   ar &
BOOST_SERIALIZATION_BASE_OBJECT_NVP(MyBaseClass);
ar.register_type(static_cast(NULL));
...
ar.register_type(static_cast(NULL));
...
...
   ar & BOOST_SERIALIZATION_NVP(m_Vector); //
std::vector
}
Got everything working but now an issue has come
up:
Someone wants to add a new class but it is not

package that is doing the serialzation.  I want to
avoid
what I call "dependency hell", is there a way for

class to get registered someplace other than in
