In addition I resurrected this post to the newsgroup. It 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 previously with boost 1.31 and serialization20 version of the library. Why would the 3 argument overload not be found? Below are the (beginnings of the ) related compiler errors.

Serialize templates classes > automatique export declaration
by Olivier Vanden Bos 11 May '05

11 May '05

I think there have been a lot of discussion about this, It might been related to the template serialization traits in the documentation , but the explanation was a little to subtle for me, \ In fact, I cannot really understand how to avoid The unregistered exception when I use a template like this. // template declaration pseudo code Class A { Virtual ~A(){}; template<class Archive> void serialize(Archive & ar, const unsigned int version){}; }; Template <T> Class B : public A { T Object; B(T& _object) { Object=_object; } template<class Archive> void serialize(Archive & ar, const unsigned int version) { Ar & Object; }; } //Main Code Vector<A*> array; Template<T> void Add(T& val) { B<T>* objectToAdd= new B<T>(val) array.push_back(objectToAdd); } //User code Add((int)0); And when i archive the array in another .cpp the exception is raised, because the class B<int> as not been exported. I would like to avoid explicitly declare BOOST_CLASS_EXPORT_GUID(B<int>, "B_int") For each instanciation of B<> somewhere in the global space. In the Add() or in the template declaration that s ok, but I cannot suppose what types that the user will use.

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(a)yahoo.com> wrote: > Date: Tue, 10 May 2005 11:24:06 -0700 (PDT) > From: kauai <kauai_diver(a)yahoo.com> > Subject: Re: [Boost-users] Re: Re: Re: Boost > serialization and dependencynightmares... > To: boost-users(a)lists.boost.org > > 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.

creating static functions with metaprogramming
by Felipe Magno de Almeida 11 May '05

11 May '05

I would like to know if it is possible to generate a number of static functions that redirect to some other function inside the class, taking an object as void * and is casted to the object (that it knows which is), and be possible to take the address of such functions... well, i dont have a good english, so I will reexplain: For the ones that already are familiar with Win32 GUI: I must create a static function to be the DialogProc of a window, the problem is... I'm creating some property sheets to be used with one class, and I would like to make it automatic the redirection from the static function to some other method inside the class, that isnt static... and I would like to create a class, probably with CRTP to say to it to create the functions that would redirect to me, saying how much functions would that be, and make it creates the codes that gives to windows the static functions addresses and create the functions that would redirect.... Then I just needed to create my functions that they redirect to me... making it a LOT easier to me, and would make my code a lot more concise... Sorry for the off-topic... But I think you would be the best ones to direct this question....

regex lib - using replace
by Lucian Ion 10 May '05

10 May '05

Hi, I need one regular expression and one format string to do the following 1) if text starts with s1, replace s1 with r1 2) else, if text starts with s2, replace s2 with r2 3) else, if text starts with s3, replace s2 with r3 4) else, prepend r3 to text While I managed to work out the first three using an expression like (^s1)|(^s2)|(^s3) and the format as 1?r1:2?r2:3?r3: I have no idea how to include the fourth case into my expression. Any suggestion? Thank you in advance, Lucian

Boos.Bind: Binding to a placeholder address
by Adi Shavit 10 May '05

10 May '05

Hi, Say have function I want to bind that expects an int*, but my placeholder _1 is of type int. How can I tell the bind function to bind "&_1"? I guess it would be something like: bind(myFun, address_of(_1)); Is this even possible? Thanks, Adi

Building Boost on MacOS 10.4 (Tiger)
by Dave Snowdon 10 May '05

10 May '05

Hello Has anyone successfully built boost on an Mac running MacOS 10.4? If so I'd appreciate some pointers on what worked for you. I've tried both boost 1.32 and a "fresh from CVS" copy with gcc 3.3 and gcc 4.0 on a Powerbook G4 with 512Mb RAM with a fresh install of MacOS 10.4. The Mac has 1.15Gb free on the startup partition and 1.36Gb free on the partition where I'm compiling boost. So far no attempt has met with success. All builds were attempted from the Terminal app with no other applications runnng. Compiling boost 1.32 with gcc 4.0 (the default compiler on MacOS 10.4) fails (unrecognised compiler version) because at the time 1.32 was released gcc 4.0 was not available. Compiling boost 1.32 with gcc 3.3 (bjam "-sTOOLS=darwin" "-sGCC=gcc-3.3" "-sGXX=gcc-3.3" stage) gives some rather strange results. Link actions seems to fail such as: ...failed darwin-Link-DyLib-action bin/boost/libs/date_time/build/libboost_date_time.dylib/darwin/debug/shared-linkable-true/libboost_date_time-d-1_32.dylib... Almost all the calls to ld gives undefined symbol errors similar to (I'm not sure if this is due to previously failed link actions): darwin-Link-DyLib-action bin/boost/libs/date_time/build/libboost_date_time.dylib/darwin/debug/shared-linkable-true/libboost_date_time-d-1_32.dylib ld: Undefined symbols: __ZNKSbIwSt11char_traitsIwESaIwEE3endEv __ZNKSbIwSt11char_traitsIwESaIwEE5beginEv __ZNKSs2atEm __ZNKSs3endEv __ZNKSs5beginEv __ZNKSs6lengthEv __ZNKSs7compareERKSs __ZNKSt11logic_error4whatEv __ZNKSt18basic_stringstreamIcSt11char_traitsIcESaIcEE3strEv __ZNKSt18basic_stringstreamIwSt11char_traitsIwESaIwEE3strEv __ZNKSt9basic_iosIcSt11char_traitsIcEE4failEv __ZNKSt9basic_iosIwSt11char_traitsIwEE4failEv __ZNKSt9type_infoeqERKS_ __ZNSaIcEC1Ev __ZNSaIcED1Ev After about 15 minutes or so the Mac grinds to a halt and starts popping up dialog boxes warning that the startup disk is full and then later that "Your Mac OS X startup disk has no more space available for application memory. To avoid problems with your computer quit any applications you may not be using" Using gcc 4.0 (bjam "-sTOOLS=darwin" stage) on the the CVS copy gives many errors similar to this: ...failed darwin-C++-action bin/boost/libs/wave/build/libboost_wave.a/darwin/release/cpp_re.o... ...skipped <@boost!libs!wave!build/libboost_wave.a/darwin/release>libboost_wave-1_33.a for lack of <@boost!libs!wave!build/libboost_wave.a/darwin/release>instantiate_cpp_exprgrammar.o... ...skipped <@boost!lib>libboost_wave-1_33.a for lack of <@boost!libs!wave!build/libboost_wave.a/darwin/release>libboost_wave-1_33.a... Previously I've been using boost 1.32 on a machine running Red Hat Linux 8 with gcc 3.2 and have not experienced any problems getting it to build. Any advice appreciated.... thanks Dave

Maybe that's a significant difference wrt to the rest of the C++ community: Many programmers are not subscribed to CUJ and do not buy intermediate/advanced books (entry-level references do not usually list Boost.) I'd like a website that holds the attention of the casual comer. A newbie with just a passing knowledge of what Boost is might be scared by the contents of boost.org and never return back; a more friendly site, with forums and stuff, is a more agreeable place to hang around and eventually decide to try Boost for real.
