Fwd: Re: [Boost-users] Re: Re: Re: Boost serialization and dependencynightmares...
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 <boost/serialization/export.hpp> // 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 <boost/serialization/export.hpp> 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. -K --- kauai <kauai_diver@yahoo.com> wrote:

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.

In addition I resurrected this post to the newsgroup.
is exactly the same problem I am having:
boost 1.32, with VC7.1 I'm getting compiler errors in two unrelated translation units both dealing with std::set<std::string> data members. I've gone through and ensured that i've #include'd the <set.hpp> and <string.hpp> headers from boost/serialization. Any ideas on what might be causing this problem? This has worked fine
with boost 1.31 and serialization20 version of the
It previously library.
Why would the 3 argument overload not be found?
Below are the (beginnings of the ) related compiler errors.
Thanks, Jeff

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.
cl /nologo /W3 /MDd /Od /EHsc /RTC1 /GS /Gy /Zc:forScope /GR /Gd /TP /D_DEBUG /D WIN32 /D_CONSOLE /D_WINDOWS /DUNICODE /DQT_DLL /DQT_THREAD_SUPPORT /IW:\vob\abvsw\boost\1_32_0\win32\include\boost-1_32 /Iroot\abcmn\ /c build-win32-debug\...\xyz.cpp /Fobui ld-win32-debug\...\xyz.obj xyz.cpp
W:\vob\abvsw\boost\1_32_0\win32\include\boost-1_32\boost\
serialization\split_free.hpp(55) : error C2780: 'void boost::archive::load(Archi ve &,T &)' : expects 2 arguments - 3 provided
W:\vob\abvsw\boost\1_32_0\win32\include\boost-1_3
2\boost\archive\detail\iserializer.hpp(514) : see declaration of 'boost::archive
load'
W:\vob\abvsw\boost\1_32_0\win32\include\boost-1_3
2\boost\serialization\split_free.hpp(54) : while compiling class-template member function 'void
boost::serialization::free_loader<Archive,T>::invoke(Archive
&,T &,const unsigned int)'
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, -K
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<SomeClass1*>(NULL));
ar.register_type(static_cast<SomeClass2*>(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

OK that's what I expect
* In Windows Server 20003 with cl version 13.10.3077 I can not compile. I get the same error message I stated earlier.
This I don't expect - we test vc 7.0, 7.1, and 8.0 without any problem like this.
Now the wierd part:
If I remove the #include <boost/serialization/export.hpp>
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
This is to be expectd
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 can't explain this.
I dont know if these annoying details may help but I just thought I'd share.
Thanks for sharing Robert Ramey
