Hi All, - I have built STL5.1.4 with VC8. - boost against stlport with the following command -> make - fvc8-stlport.mak *It created all the necessary libs and dlls. * I have defined the following in my application. *#define __STL_DEBUG #define BOOST_REGEX_DYN_LINK * But I am still getting the following linker errors. Any one can help me with these errors ? *Appreciate your help in advance* Error 3 error LNK2019: unresolved external symbol "__declspec(dllimport) public: __thiscall boost::match_results<char const

DebuggerVisualizers update
by Filip Konvička 14 Feb '08

14 Feb '08

Hi Boost, I've just updated the Debugger Visualizers wiki at http://svn.boost.org/trac/boost/wiki/DebuggerVisualizers The main change is that the visualizer files are now all available at https://svn.boost.org/svn/boost/sandbox/boost_docs/subprojects/DebuggerVisu… and, thanks to the effort and interest of Jon Fogh, there is a new visualizer for boost::interprocess::offset_ptr. Enjoy, Filip

Serialization hash_map
by christophe loustaunau 14 Feb '08

14 Feb '08

Hello, Recently I have used Boost for serialization. Unfortunatly it doesn't work with hash_map. I work with Visual 8, and Visual 8 used the dinkumware version of std lib. In order to make things working I have modified three files of boost : in the folder config/stdlib : dinkumware.hpp : BOOST_HAS_HASH is not defined.(why ?). in the folder serialization : hash_collections_load_imp.hpp : In this file I have made these changes : template<class Archive, class Container, class InputFunction> inline void load_hash_collection(Archive & ar, Container &s) { s.clear(); // retrieve number of elements unsigned int count; unsigned int item_version(0); // unsigned int bucket_count;; ar >> BOOST_SERIALIZATION_NVP(count); // if(3 < ar.get_library_version()){ // ar >> BOOST_SERIALIZATION_NVP(bucket_count); // ar >> BOOST_SERIALIZATION_NVP(item_version); // } // #if ! defined(__MWERKS__) // s.resize(bucket_count); // #endif InputFunction ifunc; while(count-- > 0){ ifunc(ar, s, item_version); } } } // namespace stl } // namespace serialization } // namespace boost hash_collections_save_imp.hpp : In this file I have made these changes : template<class Archive, class Container> inline void save_hash_collection(Archive & ar, const Container &s) { // record number of elements unsigned int count = s.size(); ar << BOOST_SERIALIZATION_NVP(count); // make sure the target type is registered so we can retrieve // the version when we load // if(3 < ar.get_library_version()){ // const unsigned int bucket_count = s.bucket_count(); // ar << BOOST_SERIALIZATION_NVP(bucket_count); // const unsigned int item_version = version<BOOST_DEDUCED_TYPENAME Container::value_type>::value; // ar << BOOST_SERIALIZATION_NVP(item_version); // } BOOST_DEDUCED_TYPENAME Container::const_iterator it = s.begin(); while(count-- > 0){ // note borland emits a no-op without the explicit namespace boost::serialization::save_construct_data_adl( ar, &(*it), boost::serialization::version< BOOST_DEDUCED_TYPENAME Container::value_type >::value ); ar << boost::serialization::make_nvp("item", *it++); } } } // namespace stl } // namespace serialization } // namespace boost With this changes Serialization of hash_map works well. Maybe you could make a : #if (!defined dinkumware ) ..... # endif In theses two files in order to make the serialization of hash_map with dinkumware working. Thanks for your time and your so good library ! -- Christophe Loustaunau.

tuple<...involves template par...>
by e r 14 Feb '08

14 Feb '08

Hi, I have the following: template<typename T> class A: public std::unary_function<const boost::tuple<double,const T&>&, void>{ public: typedef typename std::unary_function<const boost::tuple<double,const T&>&, void> parent_type; typedef typename parent_type::argument_type argument_type; void operator()(argument_type t)const{ t.get<0>(); //error: expected primary-expression before ')' token t.get<1>(); //error: expected primary-expression before ')' token }; }; Similar code without the template (i.e. fix say T = double) works fine. Anybody, pls help. Thanks.

[lambda] Compilation problem because of EXCEPTION
by Knut Hunstad 13 Feb '08

13 Feb '08

Hi! I haven't used boost much yet, but have been looking into lambda expressions. I am working within a huge system, where one of the include files has a macro definition for EXCEPTION. Which is also used as an enum value in boost/lambda/detail/arity_code.hpp (within namespace boost::lambda): enum { NONE = 0x00, // Notice we are using bits as flags here. FIRST = 0x01, SECOND = 0x02, THIRD = 0x04, EXCEPTION = 0x08, RETHROW = 0x10}; Using common names such as this in a general library seems a bit risky to me. Any header before "boost/lambda.hpp" which defines macros for any of these enum values, will cause trouble. I don't have insight enough in boost to suggest the correct solution (or to conclude that I have to fix the problem in my own code and let boost::lambda remain unchanged :-). For me right now the fix was simply replacing the (4) occurences of this EXCEPTION with LAMBDAEXCEPTION in the boost files. Where do I go to put this up as a fix-suggestion? I would like to avoid having to remember this replace every time I upgrade boost... Best regards, Knut Hunstad Vianova Systems AS Norway

[Interprocess] gcc 3.2 support?
by Matt Wharton 13 Feb '08

13 Feb '08

Greetings, So, I appear to have hit a stumbling block with GCC 3.2 and Boost.Interprocess (the latest from the release branch which I _believe_ to be the latest 1.35). Specifically, when I try to build the following code, I get numerous compilation errors (they appear to be template related). ---------------------- #include <boost/interprocess/managed_shared_memory.hpp> int main() { return 0; } ------------------------- Is there any way to get this work under my older GCC version or am I out of luck? Thanks in advance! -Matt

[boost-users] [Mixing a dll boost library with a static runtime is a really bad idea]
by chun ping wang 13 Feb '08

13 Feb '08

1.) how would I build a library in *msvc* through *nmake* so that I could get autolink to work My process is like this. a.) build my own lib file. b.) build boost lib file (succeeded) c.) build the main file and auto link to boost file (failure). 2.) What are the suggestions and requirement. 3.) Is their a way to autolink to static runtime library. Thanks.

[graph] edge_descriptor invalidation
by Sebastian Weber 13 Feb '08

13 Feb '08

Hello everyone! I'm asking myself, why edge-descriptors become invalid if I remove the edge and reinsert it? In my case the graph is represented by an adjacency list with vecS storage for vertices and edges. If I'm not mistaken, then the edge_descriptor's are just represented by pairs of vertex indices, right? So why are edge_descriptors invalid if I delete these edges, reinsert the edges and then want to use the old edge_descriptors to address those recreated edges? Most interestingly, a very cumbersome edge(source(old_descriptor, graph), target(old_descriptor, graph), graph).first gives me perfectly valid edge_descriptors again after removal and insertion. I'm confused. Thanks for any help in advance. Sebastian Weber
