boost::ptr_vector null check bloat
by Miles Bader 20 Sep '07

20 Sep '07

I tried changing some of my code that used std::vector<foo *> to using boost::ptr_vector<foo> (to get automatic deallocation and the slightly nicer syntax), but the resulting compiled code seems oddly bloated compared to the original code using std::vector. My intuition is that the two should generally compile to largely equivalent object code, except where there's a necessary functional difference. Some of the problem seems to be that it does null-pointer checking at _access_ time, instead of when adding new entries. The result is that (for instance) calls to operator[] end up with an "unnecessary" null check, which drags in tons of stuff related to the accompanying assertion failure, some of which is apparently unshared across object files, like the long __PRETTY_FUNCTION__ strings passed to the assertion failure call. What's the general impression people have of boost::ptr_vector and related classes? Do people use it? Does it have a "bloat" reputation? Thanks, -Miles -- "Suppose we've chosen the wrong god.

Getting errors while compiling a project
by Vitali Gontsharuk 20 Sep '07

20 Sep '07

Hello! I'm getting a strange problem trying to build a project of my colleague with exactly the same source, project and lib-files. I'm using Visual Studio C++ 2005 Express Edition German version with Service Pack 1. He has the same version, but in English, maybe this could be relevant. He has programmed a transforming tool which makes heavy usage of different boost features. Actually, his project used to compile on my PC previously, but then I made a Windows Update and simultaneously added some changes (included Xerces, Xalan and also changed something in my project, but didn't change anything in his project). After that I can't compile his project. I know that we use the same resource files because I downloaded them from our local svn server. I'm not sure whether I can make even parts of the code public. But maybe the full error report could be sufficient to make some hints where the problem could lie in. I would really appreciate your help, because I have already lost so much time figuring out what the problem can be. But as I'm only a novice to all the BOOST libraries, I don't have an overview of it and the typical errors and how to interpret them (or the combination of errors), which is vital in programming using templates etc. I send the full error report as an attachment! I thank all the answerers in advance! Best wishes, Vitali Gontsharuk

Problem in finding diameter and girth
by abhishek.v＠tcs.com 20 Sep '07

20 Sep '07

Hi... I want to calculate diameter and girth of a graph using BGL so i m taking http://www.cs.ualberta.ca/~ghali/courses/texts/BGL/html/girth.cpp.html#pred… as a reference. I have already created graph using adjacency_list Now i m not able to understand how to use :- typedef boost::v_property<long> dist_t; boost::property_map<Graph*, dist_t>::type d_map; typedef boost::u_property<vertex_descriptor> pred_t; boost::property_map<Graph*, pred_t>::type p_map; And for what it stands for ... Here i m not using #include <boost/graph/stanford_graph.hpp> Also let me know where it is being defined.. Is there any alternative to calculate diameter and girth Thanks Abhishek Vyas Tata Consultancy Services Mailto: abhishek.v(a)tcs.com Website: http://www.tcs.com ____________________________________________ Experience certainty.

Reference CHM
by Daniel Önnerby 20 Sep '07

Hi! Has anyone tried to generate a CHM-file of the documentation? I tried searching the net for one without any luck. I know this is a M$ format, but it's actually a great format for a reference manual and is fully integrated in many editors. Best regards Daniel

Well, you're right this global nth_index<...> and similar metafunctions are not much publicized: they are only documented in the reference, and in a little noticeable way: look for "// multi_index_container associated global class templates:" at http://www.boost.org/libs/multi_index/doc/reference/multi_index_container.h… I haven't given these global metafunctions more publicity so as to not confuse readers, given that the nested versions ought to be enough in most cases --except for broken compilers like MSVC 6.0 and, seemingly, low versions of GCC. > Again thanks alot.

Link errors using Boost & STLPort with VC8

It seems to me the reason for the failure is that there are some DLL-related conflicts. In _detect_dll_or_lib.h: # if defined (_STLP_RUNTIME_DLL) # if !defined (_STLP_USE_STATIC_LIB) # if !defined (_STLP_USE_DYNAMIC_LIB) # define _STLP_USE_DYNAMIC_LIB # endif # else /* The user is forcing use of STLport as a dynamic library. We signal * it so that the STLport namespace will be modify to report such a * combination and force the user to link with the rebuilt STLport * library. */ # define _STLP_USING_CROSS_NATIVE_RUNTIME_LIB # endif # else # if !defined(_STLP_USE_DYNAMIC_LIB) # if !defined (_STLP_USE_STATIC_LIB) # define _STLP_USE_STATIC_LIB # endif # else /* Idem previous remark but the user forces use of the static native * runtime. */ # define _STLP_USING_CROSS_NATIVE_RUNTIME_LIB # endif # endif Is it possible that such a conflict exists when libboost_regex-vc71-mt-sgdp-1_34_1.lib (my case) or libboost_regex-vc80-mt-sgdp-1_34_1.lib (OP's case) is being built? And, according to your suggestion, if I manually build libboost_regex-vc71-mt-sgdp-1_34_1.lib with cl /MTd /D_STLP_DEBUG=1 *.cpp followed by lib /out:libboost_regex-vc71-mt-sgdp-1_34_1.lib *.obj Everything is fine. Another thing to notice here is that unlike the case of STLport 4.6.2, files like boost*p-1_34_1.lib and boost*p-1_34_1.dll are NOT created. Is it related? BTW, without -D__STL_DEBUG=1 or -D_STLP_DEBUG=1 Boost will complain "STLPort debug versions are built with /D_STLP_DEBUG=1" and "Build options aren't compatible with pre-built libraries", so this should not be an issue.

Using multi-index as container type in templated class

Hello, I am having trouble using a boost::multi_index_container type in a template class where the multi-index value type is depending on the template arg type of the class. In particular, I'm getting compiler errors when trying to define the iterator and index types using the "type" typedefs in the multi_index container. Apparently, at compile time the index and iterator types cannot be deduced resulting in errors like "cannot convert to typename, etc.". I'm using GCC 3.3.1 and Boost 1.34.1. Following code demonstrates the problem: // std includes #include <iostream> // boost includes #include "boost/multi_index_container.hpp" #include "boost/multi_index/ordered_index.hpp" #include "boost/multi_index/sequenced_index.hpp" using namespace std; using namespace boost; using namespace boost::multi_index; // try also class keyword here template<typename T> class MultiIndex { public: typedef T value_type; typedef mpl::vector< ordered_non_unique<identity<value_type> >, sequenced<> > index_list_t; // multi-index typedef typedef multi_index_container< value_type, index_list_t > mi; // typedefs for index types typedef typename mi::nth_index<0>::type mi_by_value; typedef typename mi::nth_index<1>::type mi_as_seq; // typedefs for index iterators typedef typename mi::nth_index_iterator<0>::type mi_it; typedef typename mi::nth_index_iterator<1>::type mi_seq_it; MultiIndex() { // add pair to multi-index container mi_as_seq& seq = get<1>(m_c); seq.push_back(9); seq.push_back(8); seq.push_back(7); seq.push_back(6); seq.push_back(5); seq.push_back(4); seq.push_back(3); seq.push_back(2); seq.push_back(1); seq.push_back(0); } void exec() { // access as sequence cout << "\nAccessing as sequence:" << endl; copy(m_c.get<1>().begin(), m_c.get<1>().end(), ostream_iterator<int>(cout, " ")); cout << endl; // access by value cout << "\nAccessing ordered:" << endl; copy(m_c.get<0>().begin(), m_c.get<0>().end(), ostream_iterator<int>(cout, " ")); cout << endl; } private: mi m_c; }; int main(int argc, char** argv) { MultiIndex<int> mi; mi.exec(); } It's probably obvious what is wrong with this code but I just don't see it. I tried a non-templated version and that compiles (and works) fine. Thanks, Paul
