[uBLAS] operations thoughts
by vladimir josef sykora 28 Mar '03

28 Mar '03

Hello, Had a quick look into uBLAS library, and noted the incompatibility between std::vector<> and ublas' binary operations. For example, I have an ublas::matrix<> and wanted to multiply it by a std::vector<>. Since _all_ of ublas data containers provide iterators, I'm wondering why the library doesn't provide algorithms that work on iterators? In this way data structures and operators will be decoupled. For example, to do the product between a matrix and a vector: ********* untested code ********* template <class MatrixRowIterator, class MatrixColIterator, class InputIterator, class OutputIterator> OutputIterator prod(MatrixRowIterator first_row, MatrixRowIterator last_row, MatrixColIterator, InputIterator first_vec, OutputIterator result) { InputIterator cp_first=first_vec; while(first_row!=last_row) { typename MatrixRowIterator::value_type val(0); MatrixColIterator first_col, last_col; first_col=first_row.begin(); last_col=first_row.end(); while(first_col!=last_col) val+= *first_col++ * *first_vec++; *result++ = val; ++first_row; first_vec=cp_first; } return result; } // user side : prod(umatrix.begin1(), umatrix.end1(), umatrix.begin2(), std_vector.begin(), std::back_inserter(std_vector_result)); This of course with the respective preconditions. Also, wouldn't be a good idea to provide copy c'tor and operators accepting std::vector<> for the ublas::vector<> ?

BGL properties question
by Jeff Holle 28 Mar '03

28 Mar '03

I would like to write a "generic" routine that prints the named vertex and edges properties. I can see in this code sibit (from graphviz.cpp) that the info that I want is present: > vertex_label(const Vertex& u, const GraphvizDigraph& g) { > boost::property_map<GraphvizDigraph, > boost::vertex_attribute_t>::const_type > va = boost::get(boost::vertex_attribute, g); > return (*(va[u].find("label"))).second; > } It appears that va is a map<Vertex, map<string, "property value"> > How would I write code that prints the names of the properites of a given vertex? (It would involve iterating over the map whose find method is used in the above code segment).

This is correct. The 'debug' configuration is meant to work with a release version of Python, though I don't know why. However, there is no need to modify the Jamfile; just use the 'debug-python' configuration instead. Also, make sure you include <pyconfig.h> before any of the Boost.Python headers, because not all of them do that and you can end up with incorrect structure definitions in a debug build if you don't. (I should report this bug.)

newbie build question (threads and win32)
by Dave Viner 27 Mar '03

27 Mar '03

Hi, I'm trying to use Boost's threads on WIN32 using VC++ and having some difficulty. I've built the source cd D:\boost\boost_1_30_0; bjam "-sTOOLS=msvc" and after the build is done, there are some errors, but they all appear related to the regression testing. Then I cd libs\thread\build; bjam "-sTOOLS=msvc" and everything appears to work fine. However, my simple program can't compile. I get this error: d:\boost\boost_1_30_0\boost\thread\thread.hpp(17) : fatal error C1189: #error : Thread support is unavailable! My test program simply is: #include <boost/thread/thread.hpp> int main(int argc, char* argv[]) { printf("Hello World!\n"); return 0; } I can't seem to figure out why threads aren't enabled. I realize this is a very simple question, but I'd love to hear what silly thing I've done wrong. Thanks in advance for your help. dave

I agree :( I tried to use the debugger, but once it went into stlport_icl.dll I couldn't see which ostream function was being called.

test report_level in 1.30.0
by John Van Horne 27 Mar '03

27 Mar '03

We just upgraded from 1.29.0 to 1.30.0 and started having a problem running in the unit test framework. When we start the test with the command line parameter "--report_level=detailed" the tests crash. They work fine if we set the environment parameter BOOST_TEST_REPORT_LEVEL=detailed, or when we set other command line parameters, such as "--log_level=detailed". I looked at the code in libs/test/src/unit_test_main.cpp and saw that the command line parsing for report_level doesn't occur until after the unit test suite has been invoked. It appears that the unit test is then getting a command line that contains "--report_level=detailed". In our case, it doesn't know what to do with this. I hacked our copy of unit_test_main.cpp to parse the command line for --report_level before starting the unit test suite, storing the value locally. Has anyone else had this problem? Are we using the unit test framework the wrong way? Do you think I fixed it the right way, and will there be an official fix soon? Thanks, -John Van Horne

Most efficient way to convert a run of Perl substitutions til boost::regex?
by Anders Johansen 27 Mar '03

27 Mar '03

Hi! I'm converting a Perl program that basically consists of a succession of regex transformations of the input string, eg.: #Case 1 - mutually exclusive endings s/erens$/\@r\@ns_/; s/ernes$/\@rn\@s_/; s/endes$/\@n\@s_/; s/estes$/\@st\@s_/; #Case 2: - a load of manipulations done in sequence s/jou/sju/g; s/jau/sjo/g; s/nch/ngk/g; Now the question is, how do I convert this to boost::regex code that runs as fast as possible. I expect to have to call the function implementing these transformations (there are /many/) about half a million times at runtime, and as I'm concerned about runtime performance, I'd obviously like to use the most efficient method available. I expect that Case #2 is simple, as I can use the regex_merge function, and nest the calls as in: static const boost::regex re1("jou"); static const boost::regex re1("jau"); static const boost::regex re1("nch"); static const std::string fs1("sju"); static const std::string fs2("sjo"); static const std::string fs3("ngk"); std::string res = regex_merge( regex_merge( regex_merge(input_string, re1, fs1) , re2, fs2) , re3, fs3); As to case 1, I guess I'd have to use a combination of the grep and format functions, and in the case as shown it'd be easy, as there is either one match or none for each line. Any suggestions wrt. improving run-time performance? Sincerely Anders S. Johansen

Problem with 1.30.0 lexical_cast
by Tom Matelich 27 Mar '03

27 Mar '03

Compiler: gcc 3.2 and 3.2.2 I believe this is actually a bug in gcc, but I'm going to post it hopes that someone can help me. We have a handy little tool for generating enums with associated string conversion and stream insertion/extraction functions. When we upgraded to boost 1.30.0, lexical_cast'ing one of these enums to std::string started behaving incorrectly, rather than the name, it is giving me the integral value. It seems that the lexical_stream is being used. Unfortunately, my test case is working fine. The complete test case (including definition of ZAcquisition::PPG) is appended at the end. The code I am seeing failure with looks like: void foo(ZAcquisition::PPG::Type gt) { ... std::string str; str = boost::lexical_cast<std::string>(gt); std::cerr << "DEBUG, storing encode for PPG: " << str << ", aka " << gt << std::endl; ... } This outputs (for example): DEBUG, storing encode for PPG: 0, aka ONE I tried boost::lexical_cast<std::string, ZAcquisition::PPG::Type>(gt) as well. Anyone have any ideas? For now I'm going to back out to 1.29.0's lexical_cast.

I am having trouble getting the boost thread library to work. I am using Borland C++Builder 6 (on Win2k), and I tried the 1.29.0 release and the 1.30.0.b1 beta release and both give me the same errors in the condition.hpp file: line 93: " 'operator!' not implemented in type 'recursive_mutex' for arguments of the same type" and line 96: " 'recursive_mutex::m_mutex' is not accessible" Plus another 5 errors. I tried to look at the condition and recursive_mutex class definitions and I do not understand how they are implemented. Am I using it wrong to get that error? Let me know if you need a code sample.

multi_array iterators ??
by dbkita 27 Mar '03

27 Mar '03

I am intersted in a simple way to iterate on a multi_array (or better yet a multi_array_view) regardless of dimension or ranges or order of access. I suppose for the entire multi_array one can use the data() method to return a T* and step through the contiguous memory block. But the case for a multi_array_view doesn't not seem nearly so simple taking into account strides, offsets, and degenerate ranges and all. Thanks in advance for any advice.

Hi, I've got the following program to test the unit test suite: --------------------------------- // ICFGTest.cpp : Defines the entry point for the console application. // #include <boost/test/unit_test.hpp> using namespace boost::unit_test_framework; void testPass() { BOOST_CHECK( true ); } test_suite* init_unit_test_suite( int argc, char* argv[] ) { test_suite* test= BOOST_TEST_SUITE( "Test test suite" ); test->add( BOOST_TEST_CASE( &testPass )); return test; } --------------------------------- when I link this with the boost v1.30 unit test framework, I get the following linker errors: Linking... libboost_unit_test_framework.lib(unit_test_suite.obj) : error LNK2005: "public: virtual unsigned long __thiscall boost::unit_test_framework::test_case::size(void)const " (?size@test_case@unit_test_framework@boost@@UBEKXZ) already defined in ICFGTest.obj ICFGTest.obj : error LNK2019: unresolved external symbol "bool __cdecl boost::test_toolbox::detail::test_and_continue_impl(bool,struct boost::test_toolbox::detail::wrapstrstream const &,char const *,int,bool,enum boost::unit_test_framework::report_level)" (?test_and_continue_impl@detail@test_toolbox@boost @@YA_N_NABUwrapstrstream@123@PBDH0W4report_level@u nit_test_framework@3@@Z) referenced in function "void __cdecl testPass(void)" (?testPass@@YAXXZ) ICFGTest.obj : error LNK2019: unresolved external symbol "public: __thiscall boost::unit_test_framework::test_suite::test_suite(char const *)" (??0test_suite@unit_test_framework@boost@@QAE@PBD@Z) referenced in function "class boost::unit_test_framework::test_suite * __cdecl init_unit_test_suite(int,char * * const)" (?init_unit_test_suite@@YAPAVtest_suite@unit_test_ framework@boost@@HQAPAD@Z) Debug/ICFGTest.exe : fatal error LNK1120: 2 unresolved externals ------------------------ The unresolved symbol test_and_continue_impl seems most curious since one of it's parameters expects a wrapstrstream, not a wrap_strstream as the function declaration itself would suggest. Any ideas what I'm doing wrong? (NOTE: I'm linking to the static multi-threaded lib). Thanks! Dan

Spirit semantic actions and closures
by venkatram_krishnaswamy 25 Mar '03

25 Mar '03

Hi I have a question about semantic actions which generate the equivalent of synthesized attributes. It seems that the right hand side of the expression below rule = element [rule.val = val_type(some_params)]; will require the type of val in the closure associated with rule to be val_type which has a constructor which looks like val_type::val_type(some_params). Its not clear to me however how I would synthesize an attribute which is a pointer to some type. For example, in the closure I would like the type of synthesized attribute to be val_type* and for the right hand side of assignment above to be val_type(some_params)() which returns a val_type* where the following was true of the () operator : const val_type* val_type::operator () {do something and eventually return a val_type*;} I'd be very grateful if someone could clue me in on how I might do this. thanks venkat

ublas: questions from a newcomer
by stuart macgregor 25 Mar '03

25 Mar '03

I am interested in ublas for linear algebra. In addition to the simple operations supported by ublas I will need comprehensive access to lapack for the real work. I see in the wiki that some work has been done in this area. Is this numeric/binding stuff working, and can it be readily extended to the full set of lapack routines? Some kind of meta program to generate lapack interfaces from a parameter spec would be nice (ruby/perl? or just a description of what needs to be done) Then I could happily bring up the interfaces I need. Is there any way to generate vectore and matrices which do not own the data buffer which they provide access to - 'view' or 'sub' objects in other lin alg packages? This would be very valuable to me for interfacing existing code, without duplicating storage and doing unnecessary copies. I found it difficult to determine from the current documentation. I have one worry: Ublas, and most of the boost modules, seems to me not for the faint hearted. They are clearly powerful, but seem to expect a lot from a potential user. Are these facilities aimed at library writers rather than users whoes skill focus may lie in other domains? I am thinking of apl (and related J++ (not java)) which is very powerful, but has only minority appeal because it is too alien and unnatural for ordinary mortals. The advocates take great pride in how powerful a small and almost incomprehensible line of code can be (FFT in one short line etc.), and implicitly how clever they are to generate and understand it. I expect that a user level doc may eventually make ublas/lapack much more approachable by a non computer science mathematician or engineer. Forgive me if the above sounds critical and ungracious for free software, but I want to use boost and I am worried that it may be too demanding for its benefites to be justified for use by the group of people I work with. -- Stuart

[snip] > boost::shared_array<uint8> p_data(new uint8[data_length]); The above declaration of a local variable called p_data is probably not what you intended (you want to initialize the member variable p_data). If you cannot (or won't) perform the initialization in the constructor initializer, you'll need to reset the shared_array like so: p_data.reset(new uint8[data_length]); Or, in the initializer: c_Packet::c_Packet (const c_Packet & r_packet) : p_data(new uint8[r_packed.data_length]) { data_length = r_packet.data_length; ... } ...and then perform the memcpy. By the way, you are actually sharing this data, right? If not, scoped_array would probably be a better choice for managing resource lifetime. Bjorn Karlsson

shared_array with memcpy, help request

Hello everyone :) I am a new boost user, and I'm trying to convert a large project to use the smart pointers. I have a use for shared_array buy the memcpy line from the following code snippet(, and all memcpy's) throw an exception with the shared_arrays and I don't know why.

regarding the quality of math functions in stl/boost
by adam_speight 24 Mar '03

24 Mar '03

I've often heard that you should never trust your system implementation of functions like sqrt, exp, sin, cos, rand, etc. Instead, most mathematicians say that one should use an implementation that is known to be accurate up to some order. Unfortunately, using third-party code for these functions hinders portability. I know that boost has a formidable random number generation library that uses the cmath versions of basic math functions. Does the stl standard, or various implementations of stl, make any gaurantees about the accuracy of these basic math functions? Are they safe to use for mathematical applications in practice? Thanks, Adam

First problems with 1.30.0

I am trying new 1.30.0 release and got couple of problems on MSVC6 SP5.

Newbie help with date_time
by willw_at_ais 24 Mar '03

24 Mar '03

I am updating an old 1992-style application that previously used time_t based time to produce trend graphs of logged data. I am putting in ptime instead, and have come unstuck. The time range of the X-axis in this app is essentially under user control. It can show any period from a few seconds (sub seconds in the new version) up to three years. The labels on the x axis are placed at sensible points for the current range. For example if the graph shows 30 minutes, the ticks on the axis occur at 5 minute intervals; if it is displaying a week they occur on day boundaries. The old version of the program achieves this label placing by using the % operator and doing arithmetic with the seconds that underly time_t. I would like to do something similar with ptime. My attempt went like this: // Get next time (>= start) which falls on an itvl boundary ptime GetNextBoundary2(const ptime& start, const time_duration& itvl) { // Use 1/1/1970 as a base - not ideal but good enough for this const ptime origin(date(1970,1,1)); time_duration start_offset = start - origin; return ptime (start + itvl - nanosec(start_offset.ticks() % itvl.ticks())); } This fails because - among other reasons - although I can get ticks out, nanosec() won't put them back in again. I guess it is normalising on the way in? I feel sure I am going about this the wrong way, but am baffled as to what I should do next. All help gratefully received. Please be gentle with me - I am essentially a Pascal programmer who is busking, and finding this C++ template stuff hard. TIA Will Watts AIS Ltd

Const Graph Property Maps
by dmatt001 23 Mar '03

23 Mar '03

Hi Guys, I have three interesting questions in regard to graph properties. Please assume Boost 1_29_0. I'm a little slow in upgrading ... ;-) 1. If I define: MyGraph_t const myGraph; Why cannot I get a property map to access my property: typedef boost::property_map<MyGraph_t, MyPropTag_t>::type MyPropMap_t; MyPropMap_t myPropMap = get(MyPropTag_t(), myGraph); Instead I need to use for each access: get(MyPropTag_t(), myGraph, *i) I have noticed that gcc 3.2 complains in regard to conversion to a non-scalar type being similar to that of myGraph without const-ness of the nested property type. What can I do to get normal map access? 2. Why not use a copy constructor if it exists when copying graph elements? Is the existence of a copy constructor a hard-yard to verfiy with MPL? 3. I noticed that remove_edge(...) complains in regard to a missing default constructor of a property object. Don't get me wrong; this happened during an editing mishap and I know that we need regular types here. Why is this required if you are removing an element? Thanks for the pointers/opinions! :-) Matt

Suggest: tuple base class
by Bryan Silverthorn 23 Mar '03

23 Mar '03

Hi, I haven't found any discussion of this issue; it's possible I've just missed it. Anyway, the short form is that I'm trying to partially specialize a class for tuple types. I specialize for cons<H, T>, but specialization requires an exact type match, so tuple<...> will fail to match cons<...> and instead fall to the base template<class T> case--which has the wrong behavior. If I assume that the passed type is a tuple, I can use inheritance trickery and inherit from the tuple<...>::inherited case to match the correct case. Of course, this assumes that the template type is a tuple, when I can't make that assumption--I'm using specialization precisely because the type isn't known. I could specialize on tuple<T0...T9>, but that sets another arbitrary max tuple size; it would be nice to be able to match all tuples allowed by the boost::tuple implementation. So: I need a way to determine if a particular type is a tuple type, which would allow me to do the following: template<bool B, class T> class FooIf {}; template<class T> class Foo : public FooIf<is_tuple_type<T>, T> {}; template<class T> class FooIf<true, T> { /* tuple implementation */ }; template<class T> class FooIf<false, T> { /* non-tuple implementation */ }; AFAICT, there's no way to do so at present. I'd like to suggest a way to add this functionality: have cons<> (or tuple<>) inherit from a blank "tuple_base" class. This would let us use boost::is_base_and_derived to provide the is_tuple_type functionality for the code block above. Of course, it's possible I'm just missing a simple way to partially specialize for tuple types, or that such functionality is bad and unecessary. Thoughts? ---- Bryan Silverthorn :: bcs26(a)cornell.edu

Boost 1.30.0: Problems with lexical_cast together with unsigned short and MSVC7

[MPL] Comments for a newbie
by cj2048 23 Mar '03

23 Mar '03

Hello everyone, I've only recently taken my first small steps into the world of metaprogramming, and now I've hit a snag. I'm trying to create a metafunction that returns the smallest unsigned integral type with at least the specified number of bits and, if no such type exists, reports an error. For example, ceil_uint<24> (named so for lack of a better name) returns the first member of the list consisting of unsigned char short unsigned int unsigned int long unsigned int whose number of bits is greater than or equal to 24. Now, ceil_uint<N> seems to work fine for 0 <= N <= 32, but with N outside this range, g++ (3.2) gives me a compilation error: [cej@kirk aux]$ g++ -I/usr/include/boost test.cpp -o test test.cpp: In function `int main()': test.cpp:48: conversion from `int' to non-scalar type `boost::mpl::void_' requested test.cpp:49: no match for `-- boost::mpl::void_&' operator test.cpp:50: no match for `boost::mpl::void_& == unsigned char' operator test.cpp:52: no match for `boost::mpl::void_& == short unsigned int' operator test.cpp:54: no match for `boost::mpl::void_& == unsigned int' operator I guess that a compilation error is desirable in these cases, but is there some MPL-blessed way to make the error message(s) more informative (i.e., tell the user that N is outside the valid range)? I'd greatly appreciate any and all suggestions for improving the metafunction. I'd also like to know the generally recommended way to separate the "invocation" of the metafunction from its definition. I intend to invoke the metafunction in a header file like this: namespace X { /* a definition of ceil_uint here would clutter the interface of class Y */ template<int N> class Y { /* ... */ typename ceil_uint<N>::type data; // invocation }; } Having the definition and the invocation in the same header file seems to clutter the interface of the class. /* test program */ #include "boost/mpl/vector.hpp" #include "boost/mpl/find_if.hpp" #include "boost/mpl/transform.hpp" #include "boost/mpl/multiplies.hpp" #include "boost/mpl/sizeof.hpp" #include "boost/mpl/greater_equal.hpp" #include "boost/mpl/int.hpp" #include "boost/mpl/at.hpp" #include "boost/mpl/distance.hpp" #include <limits> #include <iostream> namespace mpl = boost::mpl; using namespace mpl::placeholders; template<int N> struct ceil_uint { typedef mpl::vector< unsigned char, short unsigned int, unsigned int, long unsigned int > types; typedef typename mpl::transform< types, mpl::multiplies< mpl::sizeof_<_>, mpl::int_<std::numeric_limits<unsigned char>::digits> > >::type result; typedef typename mpl::find_if< result, mpl::greater_equal< _1, mpl::int_<N> > >::type iter; typedef typename mpl::at< types, typename mpl::distance< typename mpl::begin<result>::type, iter >::type >::type type; }; int main() { ceil_uint<24>::type i = 0; --i; if (i == std::numeric_limits<unsigned char>::max()) std::cout << "\"i\" is an unsigned char." << '\n'; else if (i == std::numeric_limits<short unsigned int>::max()) std::cout << "\"i\" is a short unsigned int." << '\n'; else if (i == std::numeric_limits<unsigned int>::max()) std::cout << "\"i\" is an unsigned int." << '\n'; else std::cout << "\"i\" is a long unsigned int." << '\n'; } TIA, Christian

I knew it was a newbie error. I guess I was working too late and reading only every other line in the manual. I tell from my bad grammar. I'll try and save face by attempting to make a useful contribution. :-) Is there a debug variant or third party program that can be used to generate a useful syntax error? Note: I haven't looked at the exception generated yet but I would assume (incorrectly?) that it does not give much detail about the error. Though if you write and use expressions cleanly it should be trivial to find them by inspection. >It's an invalid expression because: > >[:punct::space:]* should be [[:punct:][:space:]]* > >and > >[-:upper::lower:^[:punct::space:]] you can't nest character >classes like that (in any regular expression language that I know of). > Bah.

Has there been any work in this direction? We want to compile the expression for efficiency reasons. Building them up using operator<< might sacrifice this without an additional "reduction" phase to compile down to the most efficient automata. I guess this would be the regexp equivalent to endl. Still I like the idea as a debugging tool and I don't think the efficiency lost would be prohibitive. Regular expressions being more like trees rather than streams the << syntax might get a bit ugly with all the brackets required. E.g. char_class Punct = regex::PUNCTUATION + regex::SPACE reg_exp WordExpression = Kleene_closure(Punct) + Positive_closure(char_class("-") + regex::ALPHA) + Kleene_closure(Punct); I guess that is pretty ugly compared to the conventional syntax, despite the improved checkability. I meant to write something like that years ago but never found the time and did have working regexp library around. How about the equivalent using some hidden template metaprogramming (for use when the expression is fixed at compile time) I have a feeling that the complexity added relative to the minor inconvenience of setting up the expression on start-up outweigh the benefits. Still I would be interested to read about research in this area (i.e. tree syntax & compile time compilation of regular expressions in C++ or other languages). With even the most elegant design there's usually a way it can be improved if you look hard enough. (perhaps that improved should be in quotes :-) I feel quite sincere about both interpretations) >> >> I found I still get rogue matches on punctuation and spaces >when I use >> the manually expanded form below: > >You are using the member first of boost::match_results as a >null terminated string - it is *Not* a copy of the string >matched or a null terminated string it is an iterator into >your text - either use the sequence (first-second), or call >match_results::str() to get a std::string object. > >John. > Bah, I even remember reading that (and doing it the first time).

1.30.0 - problem with filesystem lib
by Russ Wood 21 Mar '03

21 Mar '03

Hi, When using the filesystem lib in the 1.30.0 release, I experience hangs when incrementing the directory iterator. The compiler I've been using is MinGW, an example that exhibits the behaviour on my machine is included below. The hang only occurs when -mthreads is used. The hang occurs on the increment when there are no more files in the directory. Russ // -------------------------------------------------------- cut #include <boost/filesystem/operations.hpp> #include <boost/filesystem/path.hpp> #include <iostream> namespace fs = boost::filesystem; int main ( void ) { fs::path cwd ( fs::initial_path() ); fs::directory_iterator entry ( cwd ); fs::directory_iterator end; while ( entry != end ) { fs::path const dirent ( *entry ); std::cout << dirent.native_file_string() << std::endl; ++ entry; std::cout << "next iteration" << std::endl; } } ---- Russell Wood - Dept. of Computing, Imperial College, London.

warnings in Thread library in 1.30.0 release when compiled by VC
by huangsean 21 Mar '03

21 Mar '03

Subject: numerous warnings in Thread library in 1.30.0 release when compiled by VC7.1 (or other vc versions) with warning level 3 or above We're in the process of migrating our project from V1.29.0 to 1.30.0. We are getting a lot of warnings with thread library such as the following: c:\Program Files\Boost\boost\thread\condition.hpp(38) : warning C4275: non dll-interface class 'boost::noncopyable' used as base for dll- interface class 'boost::detail::condition_impl' I know very little about bjam but it looks like it doesn't even use /Wn switch (correct me if I am wrong and the default is /W2. IMHO, it seems to me that it is always a good practice to set the warning level to at least 3. Also, we would really really like to have the static library option back. :-) Best regards, Sean

How to build boost on Darwin/MacOSX

Hello. I'm new to Boost, and am trying to build the boost_thread library on Darwin (Mac OSX 10.2.4). I have tried 1.30.0 and the CVS version, but get a bunch of linker errors (copied below), as well as a warning about Python (which I assume is safe to ignore if I don't want Python stuff). What is the correct way to build boost on Darwin/OSX? I have tried the following: bjam boost_thread bjam -sTOOLS=gcc boost_thread bjam -sBUILD="framework bundle-loader" boost_thread bjam bjam -sTOOLS=gcc ...

Re: Boost version 1.30.0 released
by Kirill Lapshin 20 Mar '03

20 Mar '03

These are great news! Thanks to all Boost developers. One small problem though. I downloaded new release, tried to build it, and got few link errors in Boost.Test on MSVC 6. Please find log attached. __________________________________________________ Do you Yahoo!? Yahoo!

Boost version 1.30.0 released
by Beman Dawes 20 Mar '03

20 Mar '03

Boost version 1.30.0 has been released. The highlights include: * Filesystem Library added - Portable paths, iteration over directories, and other useful filesystem operations, from Beman Dawes. * Optional Library added - A discriminated-union wrapper for optional values, from Fernando Cacciola. * Interval Library added - Extends the usual arithmetic functions to mathematical intervals, from Guillaume Melquiond, Hervé Brönnimann and Sylvain Pion. * MPL added - Template metaprogramming framework of compile-time algorithms, sequences and metafunction classes, from Aleksey Gurtovoy. * Spirit Library added - An LL (unlimited lookahead) parser framework that represents parsers directly as EBNF grammars in inlined C++ source code, complete with semantic actions, ASTs and much more, from Joel de Guzman and team. * Smart Pointers Library - many enhancements, intrusive_ptr and smart pointer programming techniques docs added. * boost/assert.hpp, boost/current_function.hpp, boost/throw_exception.hpp, boost/checked_delete.hpp have been documented. * Date-Time Library - several fixes and small additions including an interface change to partial_date. * Function Library - added support for assignment to zero (to clear) and comparison against zero (to check if empty). * Operators Library - now takes advantage of named return value optimization (NRVO) when available, from Daniel Frey. * Regression Tests - Much expanded, plus a very nice summary page from Rene Rivera. * Test Library - added new facilities. * Many fixes and enhancements to other libraries. See www.boost.org for more information.

I'd have to say the integration of Terje Slettebø's fixes to lexical_cast is a major highlight.

RE: [Boost-Users] boost install and library linking
by Michael Hunley 20 Mar '03

20 Mar '03

I posted a solution to this for the v1 jambuild on the jambuild list, but not sure if anything will come of it since most of the effort is going into v2. My solution (for threads only) was to add a simple stage target at the end of the root Jamfile. Here it is: stage bin : ## Source Files ## <dll>libs/thread/build/boost_thread : ## Tags ## <tag><debug>"d" : ## default variants ## debug release ; This puts all the libs and such in $(BOOST)/bin s.t. all debug variants have are of the form <libraryname>d.<extension>. This is not completely robust (since the possible variants are huge), but it should help basic users out who need one of the generated libs. Makes linking and DLL/SO access much simpler. Under v2 it will be a different ball of wax, but much better/more maintainable (IMHO).
