[build] Creating MSVC .pdb files for static libraries
by Gary Kratkin 28 Jan '08

28 Jan '08

Hello, I'm building boost and would like to generate .pdb files for static library targets. How do I determine which dll or lib outer target is current from within an actions compile block? With that I could generate a pdb file name for /Fd. I'm working with VS2008 and boost 1_34_1 or 1_35 release branch. All help is greatly appreciated. Gary Kratkin

Install bug/workaround for 1.34.1 on cygwin.
by Greg Roach 27 Jan '08

27 Jan '08

I am trying to install boost 1.34.1 on a cygwin (x86, WinXP, NTFS) system. "make install" gives the following error: /boost_1_34_1/tools/build/v2/tools/stage.jam:424: in object(installed-shared-lib-generator)(a)4.run *** argument error * rule virtual-target.register ( target ) * called with: ( object(file-target)@1395 object(file-target)@1396 ) * extra argument object(file-target)@1396 /boost_1_34_1/tools/build/v2/build/virtual-target.jam:880:see definition of rule 'register' being called I've looked at line 424 of stage.jam. It is in the "else" block of an "if OS==NT" structure. I guess that it is wrongly detecting a linux OS - my OS is Windows. I don't know how to correct the code (I'm not familiar with this language), but by commenting out selected lines, I can force it to enter the NT block, and it all appears to work fine.

I'm also having the same problem after installing from the BoostPro Installer with VC9. Just going off the basic example, my program is: #include "stdafx.h" #include <boost/regex.hpp> #include <iostream> #include <string> using namespace std; #ifdef WIN32 int _tmain(int argc, _TCHAR* argv[]) #else int main() #endif { std::string line; boost::regex pat( "^Subject: (Re: |Aw: )*(.*)" ); while (std::cin) { std::getline(std::cin, line); boost::smatch matches; if (boost::regex_match(line, matches, pat)) std::cout << matches[2] << std::endl; } } And I'm getting: Linking... libboost_regex-vc80-mt-gd-1_34_1.lib(instances.obj) : error LNK2019: unresolved external symbol "__declspec(dllimport) public: void __thiscall std::_Container_base::_Orphan_all(void)const " (__imp_?_Orphan_all@_Container_base@std@@QBEXXZ) referenced in function "public: class std::vector<struct boost::sub_match<char const *>,class std::allocator<struct boost::sub_match<char const *> > > & __thiscall std::vector<struct boost::sub_match<char const *>,class std::allocator<struct boost::sub_match<char const *> > >::operator=(class std::vector<struct boost::sub_match<char const *>,class std::allocator<struct boost::sub_match<char const *> > > const &)" (??4?$vector@U?$sub_match@PBD@boost@@V?$allocator@U?$sub_match@PBD@boost@@@std@@@std@@QAEAAV01@ABV01@@Z) libboost_regex-vc80-mt-gd-1_34_1.lib(instances.obj) : error LNK2019: unresolved external symbol "__declspec(dllimport) public: __thiscall std::_Container_base::~_Container_base(void)" (__imp_??1_Container_base@std@@QAE@XZ) referenced in function "public: __thiscall std::_Vector_val<struct boost::sub_match<char const *>,class std::allocator<struct boost::sub_match<char const *> > >::~_Vector_val<struct boost::sub_match<char const *>,class std::allocator<struct boost::sub_match<char const *> > >(void)" (??1?$_Vector_val@U?$sub_match@PBD@boost@@V?$allocator@U?$sub_match@PBD@boost@@@std@@@std@@QAE@XZ) libboost_regex-vc80-mt-gd-1_34_1.lib(instances.obj) : error LNK2019: unresolved external symbol "__declspec(dllimport) public: __thiscall std::_Container_base::_Container_base(void)" (__imp_??0_Container_base@std@@QAE@XZ) referenced in function "protected: __thiscall std::_Vector_val<struct boost::sub_match<char const *>,class std::allocator<struct boost::sub_match<char const *> > >::_Vector_val<struct boost::sub_match<char const *>,class std::allocator<struct boost::sub_match<char const *> > >(class std::allocator<struct boost::sub_match<char const *> >)" (??0?$_Vector_val@U?$sub_match@PBD@boost@@V?$allocator@U?$sub_match@PBD@boost@@@std@@@std@@IAE@V?$allocator@U?$sub_match@PBD@boost@@@1@@Z) libboost_regex-vc80-mt-gd-1_34_1.lib(instances.obj) : error LNK2019: unresolved external symbol "__declspec(dllimport) public: void __thiscall std::_Container_base::_Swap_all(class std::_Container_base &)const " (__imp_?_Swap_all@_Container_base@std@@QBEXAAV12@@Z) referenced in function "public: void __thiscall std::vector<struct boost::sub_match<char const *>,class std::allocator<struct boost::sub_match<char const *> > >::swap(class std::vector<struct boost::sub_match<char const *>,class std::allocator<struct boost::sub_match<char const *> > > &)" (?swap@?$vector@U?$sub_match@PBD@boost@@V?$allocator@U?$sub_match@PBD@boost@@@std@@@std@@QAEXAAV12@@Z) libboost_regex-vc80-mt-gd-1_34_1.lib(instances.obj) : error LNK2019: unresolved external symbol "__declspec(dllimport) public: class std::_String_iterator<char,struct std::char_traits<char>,class std::allocator<char> > __thiscall std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> >::insert(class std::_String_iterator<char,struct std::char_traits<char>,class std::allocator<char> >,char)" (__imp_?insert@?$basic_string@DU?$char_traits@D@std@@V?$allocator@D@2@@std@@QAE?AV?$_String_iterator@DU?$char_traits@D@std@@V?$allocator@D@2@@2@V32@D@Z) referenced in function "public: struct boost::re_detail::re_syntax_base * __thiscall boost::re_detail::basic_regex_creator<char,struct boost::regex_traits<char,class boost::w32_regex_traits<char> > >::append_set(class boost::re_detail::basic_char_set<char,struct boost::regex_traits<char,class boost::w32_regex_traits<char> > > const &,struct boost::mpl::bool_<0> *)" (?append_set@?$basic_regex_creator@DU?$regex_traits@DV?$w32_regex_traits@D@boost@@@boost@@@re_detail@boost@@QAEPAUre_syntax_base@23@ABV?$basic_char_set@DU?$regex_traits@DV?$w32_regex_traits@D@boost@@@boost@@@23@PAU?$bool_@$0A@@mpl@3@@Z) C:\Documents and Settings\corwin\My Documents\Visual Studio 2008\Projects\Bella\Debug\Bella.exe : fatal error LNK1120: 5 unresolved externals David Randolph Palmer wrote: > > I was able to build everything, but now get link errors, anyone know the > answer?

Building ASIO as a universal binary in Leopard
by Derrick Hathaway 27 Jan '08

27 Jan '08

I'm running OS X Leopard on an intel Macbook. I was able to muddle through getting 1.34.1 built universal. In order to build Boost universal, I followed the instructions I stumbled upon here: http://woldlab.caltech.edu/cgi-bin/mussa/wiki/OSXUniversalDependencies I modified it slightly to build with the OS 10.5 sdk. I have appended my user-config.jam file. I am interested in using ASIO, which depends upon Boost.System. Boost.System is not included in 1.34.1, but it is included in the ASIO download. I can build and have built system according to the instructions in the ASIO README, but these instructions result in an i386 only build. Any ideas how I can build and install Boost.System universal with 1.34.1? Or, is there a better way altogether? Thanks in advance.

Hi is their anyway for boost to allow only explicit conversion... like class MyInt { // some code inside.... operator int() {} }; myIntCalc(int, int); MyInt a, b; f = myInt(a, b); // compile error no implicit conversion. int x = boost::numeric_cast<int>(a); // k allow int y = static_cast<int>(b); // k allow.

[review] Review of Flyweight library started January 21 and still running!
by Ion Gaztañaga 26 Jan '08

26 Jan '08

Hi all, The formal review of Flyweight library started January 21 and will end January 30, we have a few nice reviews, but I'm sure that those who haven't reviewed it are also interested in the library ;-). The library solves quite a common programming pattern, is small and very well documented. So don't be afraid to try it! Information for reviewers: *Description:* Flyweights are small-sized handle classes granting constant access to shared common data, thus allowing for the management of large amounts of entities within reasonable memory limits. Boost.Flyweight makes it easy to use this common programming idiom by providing the class template flyweight<T>, which acts as a drop-in replacement for const T. *Online docs:* http://tinyurl.com/2sstyr http://svn.boost.org/svn/boost/sandbox/flyweight/libs/flyweight/index.html *Download:* http://tinyurl.com/hrdm6 http://www.boost-consulting.com/vault/index.php?&direction=0&order=&directo… *Notes:* 1) We've seen some suggestions in the mailing list for Flyweight. Joaquín has nicely explained a couple of issues that we'd like to address/discuss in the review: http://tinyurl.com/33ghtf http://svn.boost.org/svn/boost/sandbox/flyweight/libs/flyweight/doc/review_… 2) Flyweight needs Boost 1.35 elements because the library depends on libraries like Interprocess for some features/tests. Since SVN snapshot tarballs seem to be missing these days, those who want to try flyweight can download a working SVN-HEAD snapshot here: http://igaztanaga.drivehq.com/boost_trunk.tar.bz2 3) Serialization tests won't work. This feature is expected to work when some new features (discussed in the mailing list between Joaquín and Robert Ramey) are added in Boost.Serialization. Those are expected for Boost 1.36. What to include in Review Comments ================================== Your comments may be brief or lengthy, but basically the Review Manager needs your evaluation of the library. If you identify problems along the way, please note if they are minor, serious, or showstoppers. Here are some questions you might want to answer in your review: * What is your evaluation of the design? * What is your evaluation of the implementation? * What is your evaluation of the documentation? * What is your evaluation of the potential usefulness of the library? * Did you try to use the library? With what compiler? Did you have any problems? * How much effort did you put into your evaluation? A glance? A quick reading? In-depth study? * Are you knowledgeable about the problem domain? And finally, every review should answer this question: * Do you think the library should be accepted as a Boost library? Be sure to say this explicitly so that your other comments don't obscure your overall opinion. Ion Gaztañaga - Review Manager -

[serialization] hash_map declaration problem
by Jan Boehme 26 Jan '08

26 Jan '08

Hi, I encountered problems while trying to serialize hash_maps which use pool allocators ( gcc: no member 'serialize' ). I had a look into "boost/serialization/hash_map.hpp" and realized a problem in the declaration of hash_map in here: BOOST_STD_EXTENSION_NAMESPACE::hash_map<Key, HashFcn, EqualKey, Allocator> should be BOOST_STD_EXTENSION_NAMESPACE::hash_map<Key, Value, HashFcn, EqualKey, Allocator> It seems that nobody used the hash_map with more than 4 template parameters together with boost::serialization before. It would be nice, if the following changes for "boost/serialization/hash_map.hpp" would be adopted into the repos. Cheers, Jan. --- /boost-trunk/boost/serialization/hash_map.hpp 2007-08-01 09:03: 26.000000000 +0200 +++ /boost/serialization/hash_map.hpp 2007-12-17 11:36:27.000000000 +0100 @@ -33,3 +33,4 @@ class Archive, - class Key, + class Key, + class Value, class HashFcn, @@ -41,3 +42,3 @@ const BOOST_STD_EXTENSION_NAMESPACE::hash_map< - Key, HashFcn, EqualKey, Allocator + Key, Value, HashFcn, EqualKey, Allocator > &t, @@ -48,3 +49,3 @@ BOOST_STD_EXTENSION_NAMESPACE::hash_map< - Key, HashFcn, EqualKey, Allocator + Key, Value, HashFcn, EqualKey, Allocator > @@ -55,3 +56,4 @@ class Archive, - class Key, + class Key, + class Value, class HashFcn, @@ -63,3 +65,3 @@ BOOST_STD_EXTENSION_NAMESPACE::hash_map< - Key, HashFcn, EqualKey, Allocator + Key, Value, HashFcn, EqualKey, Allocator > &t, @@ -70,3 +72,3 @@ BOOST_STD_EXTENSION_NAMESPACE::hash_map< - Key, HashFcn, EqualKey, Allocator + Key, Value, HashFcn, EqualKey, Allocator >, @@ -75,3 +77,3 @@ BOOST_STD_EXTENSION_NAMESPACE::hash_map< - Key, HashFcn, EqualKey, Allocator + Key, Value, HashFcn, EqualKey, Allocator > @@ -85,3 +87,4 @@ class Archive, - class Key, + class Key, + class Value, class HashFcn, @@ -93,3 +96,3 @@ BOOST_STD_EXTENSION_NAMESPACE::hash_map< - Key, HashFcn, EqualKey, Allocator + Key, Value, HashFcn, EqualKey, Allocator > &t,

Multiple templates singletons
by Hicham Mouline 25 Jan '08

25 Jan '08

Hi, I have a template class with 6 template arguments as : template <typename contractType, typename treeType, int n, enum1 rtype, enum2 qtype, enum3 vtype> class TreeImpl {}; I need to write partial specializations for the cases n=2, n=3, for 2 cases of rtype, 2 cases of qtype and 3 cases of vtype, therefore I will write 2*2*2*3 = 24 partial specializations. Any fully specialized template instance should be a singleton. I would like to find a way to store any instanciated full specialization in some common list, so that in other parts of the code, i can deal with the various singletons without having to write actual arguments n,rtype,qtype and vtype. I thought of having all these templates inherit from a template base class template <typename contractType, typename treeType> class TreeImplBase; Each specialization of these holds a static std::map< boost::tuple<int,enum1,enum2,enum3>, const TreeImplBase* >; which contains the list of the derived template classes. Any comments are appreciated, Perhaps this is a known design pattern, perhaps there is an easier way of doing this, perhaps there is a boost library which helps with this, regards,

Dear all, I am using a boost::date_time::local_date_time and I have a problem when a local_date_time is declared as class member. Case 1 class toto { protected: boost::local_time::local_date_time tt ; public: toto(boost::local_time::local_date_time t) : tt(t) {} ~toto(){} }; => compil ok =========== Case 2 (using '=' operator) class toto { protected: boost::local_time::local_date_time tt ; public: toto(boost::local_time::local_date_time t) { tt=t; } ~toto(){} }; => does not compiles !
