AIX (xlC v6.0) and Boost
by Bryan Ewbank 08 Mar '07

08 Mar '07

Hello Boosters, I tried searching for previous discussion of this issue, and did not locate anything; my apologies if I missed it... I found a problem in the boost_1_33_1 file config/compiler/vacpp.hpp for version 6.0 of that compiler. I was getting the classic error message from the xlC linker caused by undefined class-level static variables: ld: 0711-317 ERROR: Undefined symbol: boost::details::pool::ct_lcm<8,8>::value ld: 0711-317 ERROR: Undefined symbol: boost::pool<boost::default_user_allocator_new_delete>::min_alloc_size After rooting around a bit, I ended up setting the configuration switch BOOST_NO_INCLASS_MEMBER_INITIALIZATION for v6.0. It is already set for v5.2 and earlier versions, but it was not set for v6.0 . In any case, enabling this switch (and thus using enums instead of class-static variables), the compiler problems ceased. How do I make sure this gets added to the boost config files? - Bryan E

Copy editing documentation
by Nava Whiteford 08 Mar '07

08 Mar '07

Hi, I'm reading though the boost unit testing documentation at: http://www.boost.org/libs/test/doc/components/utf/index.html It's good, but I think could probably do with some basic copy editing. As I'm reading though it anyway I'd be happy to do it, is this ok? What procedure should I follow to do this? Many Thanks! --

[Boost-bugs] [ boost-Bugs-1676565 ] boost::format and operator priority rule
by SourceForge.net 08 Mar '07

Bugs item #1676565, was opened at 2007-03-08 06:37 Message generated for change (Tracker Item Submitted) made by Item Submitter You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=107586&aid=1676565&group_… Please note that this message will contain a full copy of the comment thread, including the initial issue submission, for this request, not just the latest update. Category: None Group: None Status: Open Resolution: None Priority: 5 Private: No Submitted By: Nobody/Anonymous (nobody) Assigned to: Nobody/Anonymous (nobody) Summary: boost::format and operator priority rule Initial Comment: boost::format uses operator % to "feed" a string to a formatter, as in cout<<format("Choose %1% of %2%") % 5 % 37; //writes "Choose 5 of 37" This leads to a compile-time error when arithmetic operations are used without parenthesizing, e.g. cout<<format("Choose %1% of %2%") % total-remaining+1 % total; //WRONG, tries to apply operator - to a formatter because operator % has a higher priority than operator - . This is indeed quite a common case; I suggest that operator % be replaced with an operator with lower priority, such as << . I can't figure out why operator % was chosen, is there a reason to use it?

FYI: pp-lib configuration update
by Paul Mensonides 08 Mar '07

08 Mar '07

I just updated the EDG configuration of the pp-lib on both the trunk and the release branch at the request of EDG. EDG's newest front-end preprocessor goes into a Microsoft-emulation mode when the compiler proper is set to run in Microsoft-emulation mode. Because of that, the pp-lib will fail without the configuration choosing the MSVC configuration when EDG is running in Microsoft-emulation mode--hence the change. Regards, Paul Mensonides

greetings all, long time user and lurker, low probability poster... i've been mulling over an SoC proposal for Boost.Graph based on work i've been doing over the past year related to measures on random graphs. specifically, i've been building up a set of graph algorithms using boost graph to compute (for example) degree distributions, clustering coefficient, mean geodesic distance and diameter, clique counts, etc. i had also noticed on the wiki that there were some proposals for fixing documentation, examples, and even a boost graph 2 library. part of my intended proposal was to spend some time working on these issues like moving the documentation to Boost.Book (if it hasn't been done) and improving it, making the examples a little bit more readable and commented, basic housekeeping type stuff. one of the other ideas i've been kicking around was how to rewrite Boost.Graph using Boost.MPL. i had intended part of the deliverables to be a proposed redesign and evaluation. this would address issues like basic graph wrappers (directed, undirected), hypergraphs (edges with more than 2 or more endpoints), etc. quick background... i'm a phd student at kent state doing research in software engineering. the reason i'm proposing work on Boost.Graph is because i've been using it for class projects to measure features of massive software graphs derived from type references. so... if anybody thinks this project is worthwhile and would be interested in mentoring, i'd like to know. thanks, andrew sutton asutton(a)cs.kent.edu

Unicode Library
by Emery De Nuccio 08 Mar '07

I have been using a set of Unicode classes that I wrote that follow the STL common conventions for a while. These include unicode::ustring to replace std::string, unicode::uifstream to replace std::uifstream, and unicode::uofstream to replace std::ofstream. Is there any interest in adding them to Boost? I was pretty shocked to find that boost doesn't already have something like this (or maybe it does and I just haven't found it). Each of the classes mimics the standard equivalents' design like member names and iterator sub-classes. They also bidirectionally support all of UTF-8, UTF-16, UTF-32/UCS-4, UCS-2, and traditional ASCII. The only thing that I think is lacking is regex - not sure how to go about that. Maybe collaborate with the current boost.regex author(s) to add non-PCRE Unicode support? Note: I am happy do the necessary work to make the library meet Boost's quality standards.

library contain vector(any static size), matrix 4x4, quaternion, plane(3D), sphere(3D), AABB(3D) and have little fuzzy logic support. This is little code snippet of vector class: ... template < typename T, IT N, template<class> class IPolicy > class Vector : private IPolicy<T> { public: typedef Vector<T, N, IPolicy> VectorType; typedef T value_type; typedef T* iterator; typedef const T* const_iterator; public: Vector() { IPolicy<T>::construct<N>( _a ); } // copy constructor & assigment operator are fine // (hold objects by value) template<IT M> explicit Vector( const Vector<T, M>& rhs ) { enum { copy_sz = smin<M, N>::result }; std::copy(rhs._a, rhs._a + copy_sz, _a); IPolicy<T>::construct<N - copy_sz>( _a + copy_sz ); } explicit Vector( const T& val ) { nInternal::for_each_set<T, N>::Do(_a, val); } Vector ( const T& x, const T& y, typename boost::enable_if_c<(N == 2)> * = 0 ) { _a[0] = x; _a[1] = y; } Vector ( const T& x, const T& y, const T& z, typename boost::enable_if_c<(N == 3)> * = 0 ) { _a[0] = x; _a[1] = y; _a[2] = z; } Vector ( const T& x, const T& y, const T& z, const T& w, typename boost::enable_if_c<(N == 4)> * = 0 ) { _a[0] = x; _a[1] = y; _a[2] = z; _a[3] = w; } template<IT M> explicit Vector( const T (&arg)[M] ) { enum { copy_sz = smin<M, N>::result }; std::copy(arg, arg + copy_sz, _a); IPolicy<T>::construct<N - copy_sz>( _a + copy_sz ); } template<IT M> Vector& operator = ( const T (&arg)[M] ) { enum { copy_sz = smin<M, N>::result }; std::copy(arg, arg + copy_sz, _a); IPolicy<T>::construct<N - copy_sz>( _a + copy_sz ); return *this; } template<IT M> Vector& operator = ( const Vector<T, M>& rhs ) { return operator = ( rhs._a ); } Vector& operator = ( const T& val ) { Fill(val); return *this; } T& operator [] ( IT idx ) { return _a[idx]; } T& at( IT idx ) { if( idx < N ) return _a[idx]; throw std::out_of_range(typeid(*this).name()); } template<IT I> T& at_c() { BOOST_STATIC_ASSERT( I < N ); return _a[I]; } const T& operator [] ( IT idx ) const { return const_cast<VectorType*>(this)->operator [](idx); } const T& at( IT idx ) const { return const_cast<VectorType*>(this)->at(idx); } template<IT I> const T& at_c() const { return const_cast<VectorType*>(this)->at_c<I>(); } const_iterator begin() const { return &_a[0]; } iterator begin() { return &_a[0]; } const_iterator end() const { return &_a[N]; } iterator end() { return &_a[N]; } template<template<class> class IP> operator Vector<T, N, IP>& () { return reinterpret_cast<Vector<T, N, IP>&>(*this); } T& x( typename boost::enable_if_c<(N > 0)> * = 0 ) { return _a[0]; } T& y( typename boost::enable_if_c<(N > 1)> * = 0 ) { return _a[1]; } T& z( typename boost::enable_if_c<(N > 2)> * = 0 ) { return _a[2]; } T& w( typename boost::enable_if_c<(N > 3)> * = 0 ) { return _a[3]; } Vector operator - () const { Vector ret; nInternal::neg_op<T, N>::Do(_a, ret._a); return ret; } bool IsEqual( const VectorType& vec, const T& accuracy ) const { return nInternal::cmp_op<T, N>::Do ( _a, vec._a, nInternal::not_near<T>(accuracy) ); } bool operator == ( const VectorType& vec ) const { return nInternal::cmp_op<T, N>::Do(_a, vec._a, std::not_equal_to<T>()); } bool operator != ( const VectorType& vec ) const { return nInternal::cmp_op<T, N>::Do(_a, vec._a, std::equal_to<T>()); } bool operator < ( const VectorType& vec ) const { return nInternal::cmp_op<T, N>::Do ( _a, vec._a, std::not2(std::less<T>()) ); } Vector& operator += ( const VectorType& other ) { nInternal::bin_op<T, N>::Do ( _a, _a, other._a, std::plus<T>() ); return *this; } Vector& operator -= ( const VectorType& other ) { nInternal::bin_op<T, N>::Do ( _a, _a, other._a, std::minus<T>() ); return *this; } Vector& operator *= ( const VectorType& other ) { nInternal::bin_op<T, N>::Do ( _a, _a, other._a, std::multiplies<T>() ); return *this; } Vector& operator /= ( const VectorType& other ) { nInternal::bin_op<T, N>::Do ( _a, _a, other._a, std::divides<T>() ); return *this; } ... }; Little sample: Vector<3, float> v0(0.f, 1.f, 2.f), v1(1.f), v2(v0 + v1); float _x = v0.x(), _x0 = v0[0], _x1 = v0.at(-1);
