iterator_adaptors Comment
by Duane Murphy 14 Jan '02

14 Jan '02

There is a comment in iterator_adaptors: public: // implementation details (too many compilers have trouble when these are private). Policies& policies() { return m_iter_p.second(); } const Policies& policies() const { return m_iter_p.second(); } Base& iter() { return m_iter_p.first(); } const Base& iter() const { return m_iter_p.first(); } This seems to imply that iter() and policies() ought to be private. I would like to suggest that having access to the underlying iterator is valuable. This is especially true of transform and projection iterators which allow you to locate a record by searching on a field. Access to the underlying iterator gets access to the rest of the record. Is there some other way of accomplishing the same thing without using iter()? Thanks, ...Duane

iterator_adaptor const iterator question
by Duane Murphy 14 Jan '02

14 Jan '02

I have now built a couple of iterators using boost::iterator_adaptor. These are not adapted iterators but rather iterators developed to iterate over interfaces that have not iterators. I havent found a good example of how to declare the equivalent of a const_iterator like in vector. What would the declartion look like? If the definition of an iterator is: typedef boost::iterator_adaptor< Base, Policy > iterator; What would the declartion for a const_iterator look like? Thanks for the help. ..Duane

Hello, compiling the 'regex_split example: split a string into tokens' failed with an 'undefined symbols' message (see below). I am using Project Builder 1.1.1 the following compiler: Apple Computer, Inc. version gcc-934.3, based on gcc version 2.95.2 19991024 (release) on MacOSX 10.1.2 (Unix BSD 4.4). Any help would be much appreciated.

tuple I/O trouble
by s1imshady86 11 Jan '02

11 Jan '02

When my test program gets to the cout << a; line i get a external error. As far as i can tell the library is setup right. I had no problem using tuples in other programs but cant seem to print them. The documentation doesn't list this feature as broken on my compiler or any compiler for that matter. Im using MSVSC++ btw. #include <iostream> #include <boost/tuple/tuple_io.hpp> using namespace std; using namespace boost; int main () { tuple<int,int> a (23,42); cout << a; return 0; } heres the error verbatim: --------------------Configuration: Tuple - Win32 Debug---------------- ---- Compiling... Test.cpp Linking... Test.obj : error LNK2001: unresolved external symbol "private: static int const * const boost::tuples::detail::format_info::stream_index" (?stream_index@format_info@detail@tuples@boost@@0QBHB) Debug/Tuple.exe : fatal error LNK1120: 1 unresolved externals Error executing link.exe.

Using boost::thread under Visual C++
by cadenzajon 10 Jan '02

10 Jan '02

Hi all, I'm starting to use boost for the first time now, but I'm having problems linking to the thread library (libboost_thread.lib) from within Visual C++. Using my main compiler, VC++ 6.0, I get the following linker error: libboost_thread.lib(exceptions.obj) : error LNK2001: unresolved external symbol "__declspec(dllimport) public: __thiscall std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> >::basic_string<char,struct std::char_traits<ch ar>,class std::allocator<char> >(char const *)" I checked the compiler compatibility tables online at the boost site, but they're not recent enough to include any details on the thread library. When I use Visual C++ .NET (feel free to shrink away in horror) to test it, I get about 8 linker errors complaining that a handful of standard library functions (most dealing with the basic_string and exception classes) are being redefined by libboost_thread.lib. Does anybody have any experience with this or ideas on what I could be doing wrong? I'm just starting to do multi-platform software design, and boost::thread would be a godsend! Thanks, Jonathan

Hello, I am currently trying to build Boost on MacOSX 10.1.2. I 'made' Jam for MacOSX then typed jam -sBOOST_ROOT=. -sTOOLS="gcc" to build Boost.

New poll for Boost-Users
by Boost-Users＠yahoogroups.com 10 Jan '02

10 Jan '02

Enter your vote today! A new poll has been created for the Boost-Users group: Yahoo! groups can be configured so that only the moderators can view membership list, or so that membership lists can be viewed by anyone (email addresses are always munged for non-moderators; my email address would appear as something like jim.hyslop@.le...) Do you want the membership list to be freely available to be viewed by anyone, or do you want the membership list kept private so only the moderators can view the list? o I want only the moderators to be able to view the membership list o I want anyone to be able to view the membership list To vote, please visit the following web page: http://groups.yahoo.com/group/Boost-Users/polls Note: Please do not reply to this message. Poll votes are not collected via email. To vote, you must go to the Yahoo! Groups web site listed above. Thanks!
