link problem of boost.thread in vc7.1
by hj 29 Jun '05

29 Jun '05

I use VC7.1 to compile it into boost_thread-vc71-mt-gd-1_32.lib. But I cannot link it into a MFC applicatioin(_MDd code generation). I get the error like this:"error LNK2019: unresolved external symbol "__declspec(dllimport) public: void __thiscall boost::thread::join(void)" (__imp_?join@thread@boost@@QAEXXZ) referenced in function "public: virtual int __thiscall CserverApp::InitInstance(void)" (?InitInstance@CserverApp@@UAEHXZ)" Anyone can help me? Thank you:)

old_numeric_cast and Borland 5.6.4
by Fernando Cacciola 28 Jun '05

28 Jun '05

Hi, According the a recent status report, consersion/cast_test.cpp is still failing for Borland 5.6.4 The report details shows that the implementation is not being redirected to the old code, as it should for this compiler, even though this line: #if BOOST_WORKAROUND(BOOST_MSVC, < 1300) || BOOST_WORKAROUND(__BORLANDC__, == 0x564) # include<boost/numeric/conversion/detail/old_numeric_cast.hpp> #else is supposed to do that? Isn't 0x564 the version macro number for this compiler? Any ideas? TIA Fernando Cacciola

[regex] Compiler warnings
by Markus Schöpflin 28 Jun '05

28 Jun '05

Currently I get two warning when compiling regex with gcc-3.2.3 on Tru64 and I think the warnings are justified. The first one is in "basic_regex_parser.hpp" at line 1284 where it complains about a signed/unsigned mismatch. The code in question is "(i > (std::numeric_limits<charT>::max)())" where i is an int and charT=wchar_t is unsigned. Isn't there a conversion missing here? The second one is in "cpp_regex_traits.hpp" at line 970. There is a "BOOST_USE_FACET(std::numpunct<char>, ...)" which I think should read "BOOST_USE_FACET(std::numpunct<charT>, ...)". Markus

[Dick] Nope, not sure at all. I overlooked "limited to linux on arm". (At any given time our "build" currently uses six instances of gcc - various PowerPC, x86 look-a-likes, DSPs, etc. - and I'll worry about those later.) Yes, your suggestion to put the test in libstdcpp3.hpp seems like it would work nicely.

[Dick] Once again I yelled before I was bit. I'm haven't been able to get bjam --v2 to pass BOOST_HAS_THREADS to the compiler so I ass-u-me-D it was some magic cookie that was being #undefD in preparation for use as a flag. Dumb. I'll go back to the boost.build list with this now. Thanks for the mentoring. > John. > [Dick] Regards, Dick

[dynamic_bitset]bit insertion and extraction from c.l.c++

It can according to: http://www.boost.org/libs/dynamic_bitset/dynamic_bitset.html#header-files You would use the constructor that takes two input iterators. Since this is a templated constructor, Buffer elements don't have to be 8bit bytes. boost::dynamic_bitset<> bits( &Buffer[0], &Buffer[0] + 207 ); Also see the non-member functions from_block_range,to_block_range and to_ulong that allow transfer from/to integral data types. The latter could be used to create a templated function to implement your desired behavior. // Untested and needs error checking template< typename T, class BITSET > T extract_value( BITSET aBits, size_t aBegin, size_t aSize ) { // implement size assertions here aBits.resize( aBegin + aSize ); return T((aBits<<aBegin).to_ulong()); } I'm surprised that this wasn't available for either std::bitset or boost::dynamic_bitset. Any particular reasons? Would a function with this ability be a useful addition? Certainly a more efficient implementation would be desirable. Jeff Flinn

[acc][serialization] Boost.Serialization marked as unusable
by JOAQUIN LOPEZ MU?Z 28 Jun '05

28 Jun '05

Hello, Boost.Serialization is marked as unusable for the HP aCC* family of compilers, but a test of Boost.MultiIndex involving serialization seems to work OK in FFT-aCC (http://tinyurl.com/9xsd2, test_serialization), so I understand Boost.Serialization works for this compiler after all. OK to unmark? If nobody does it first, I can do it myself in ~10 hours. Thank you, Joaquín M López Muñoz Telefónica, Investigación y Desarrollo

intrusive list
by Geoff Carlton 27 Jun '05

27 Jun '05

I've just come across the intrusive list class in the sandbox. I've been searching for a class like this for quite some time, but I never thought to look through the boost sandbox area for it. I can finally ditch my own partial implementation and use this nice alternative! One issue I have seen with this class is that it destroys its nodes on list destruction. Previously implementations I have seen instead assert(empty()), leaving it up to the programmer to explicitly decide what to do. In some cases it is indeed to clear the list, but in others it may be to dethread the list and do something else entirely with the nodes. An example is in the common pattern: array<particle> myPool; ilist<particle> activeList; ilist<particle> freeList; Under this scheme the nodes were allocated in the array and then threaded onto their respective lists. As such, automatic deletion would cause a crash, and the programmer should instead just "leak" the list back into the array. Another disadvantage of the destructor calling clear() is that it prevents the node class from having a private destructor. Objects may need to be deleted via a manager class, however the destructor's clear() will cause a compile error in this situation. I find it interesting that under the "move sematics" C++0x proposal, the ilist could be given move sematics and thus fit into STL containers. Is there any ongoing interest in this class, and will it eventually make it into the boost proper? Geoff
