The headers would be a good start :-) You will need to define BOOST_REGEX_DYN_LINK when building so that the regex lib knows to import code from a dll, otherwise the default is for it to expect to static link. And also note that there are two dll's for VC8, one for the debug runtime and one for the release runtime. HTH, John.

[Intrusive] augmenting red black trees
by George Slavov 30 Mar '09

30 Mar '09

I want to know if it's possible to augment the red black tree structure offered by Boost.Intrusive. Specifically I need each node to contain some information like the max value of the subtree rooted at that node and this information should be updated during insert/delete operations. This is a fairly common thing, allowing you to do logarithmic queries that are specific to certain trees, so I'm surprised I couldn't find anything about it in the Boost.Intrusive docs. Regards, George Slavov

Thread local storage
by Oliver Abert 30 Mar '09

30 Mar '09

Hi Everyone, I am using Boost Threads (1.38) as threading library and I also use the thread_specific_ptr to store a minor amount of data per thread (I think currently it is like 5 different pointer values per thread). Technically everything works out fine, but I am having a performance problem on Mac OS X. On Linux the performance is 10 times faster than on Mac OS. If I use pthreads on Mac OS I have identical performance to the Linux version. Both versions are running on the same machine using 8 threads both. Is there any known problem with shared pointers on Mac OS? I have tried different versions of boost, compiled it myself and also used macports - every time same results on Mac OS. Any hit or possible workaround is very welcome :) Thanks and regards, Oliver

[asio] skipping data in tcp stream
by Roman Shmelev 30 Mar '09

30 Mar '09

HI! What we have: tcp connection, from which we read messages. each message = header(fixed len) + body(random len) header contains the length of body and crc to check if the header is not corrupted. Reading is done in two async steps - first the header is read, then memory for body is allocated and the body is read. Questions are: 1) if header is corrupted under some cases (header crc says body len could be wrong) then as I understand we must skip all body data and read the next message. How to skip? async_read_until seemed to be the solution, but manual told that it may read surplus data into streambuf - it will be hard to deal with that data because I am reading directly from socket to some allocated memory (as was told above) 2) actually, can it be that in tcp stream data will be corrupted? I guess, yes - so header contains bodylen and crc for body and for header? is such solution an overhead? 3) maybe I do some global design mistakes? Thank you!

String processing algorithms
by Aggelidis Nikos 30 Mar '09

30 Mar '09

hi to all,i am interested in implementing some string processing algorithms{eg boyer-moore , knuth morris prat} for educational purposes. This is the first "real" exposure i will have with boost. I've done a bit of searching and i think Xpressive is the corresponding library of boost, for string processing. From what i read Xpressive is a header-only template library, so i will have to study xpressive.hpp . Any other directions i should follow? thanks in advance for your trouble, nicolas

[boost][system] Linking problems with C++0x, boost 1.38, Intel C++ 11.0 on windows
by Jesse Perla 30 Mar '09

30 Mar '09

Just to see if it was possible and if I could use "auto", I tried to compile my program with /Qstd:C++0x on Intel Windows 11.0. I am using boost::filesystem (which I assume uses boost::system). I did not recompile these binaries with this flag turned on (partially because I don't know how to mess with bjam or if I needed to mess with settings). The only thing that appears to be failing is linking to boost system. I get the following unresolved externals: 1>sandbox.obj : error LNK2019: unresolved external symbol "class boost::system::error_category const & __cdecl boost::system::get_system_category(void)" (?get_system_category@system @boost@@YAABVerror_category@12@XZ) referenced in function ___sti__$E 1>sandbox.obj : error LNK2019: unresolved external symbol "class boost::system::error_category const & __cdecl boost::system::get_generic_category(void)" (?get_generic_category@system @boost@@YAABVerror_category@12@XZ) referenced in function ___sti__$E I thought maybe automatic linking was buggy, so I tried to add the following to linker inputs, but no luck: libboost_system-iw-mt-gd-1_38.lib Any ideas? Thanks, -Jesse

[boost] Any experiences with C++0x features with Intel C++ 11.0 on windows and boost?
by Jesse Perla 29 Mar '09

29 Mar '09

Has anyone tried messing around with the /Qstd:C++0x setting on Intel C++ 11.0 and used boost in the same project? I would love to use "auto" and simple "decltype" if possible, but I don't want to waste a bunch of time if this isn't likely to work with boost or is known to cause incomprehensible errors when mixed with older style generic programming. What about really simple use of the new lambdas? In practice, do you think this is premature and likely to cause major regressions in the future? I can't see how "auto" or "decltype" would change, but is simple lambda usage fairly stable in the converging C++0x specs? -Jesse

[parameter]Boost Parameter and template template arguments
by Jesse Perla 29 Mar '09

29 Mar '09

I have a class template with a large number of potential template parameters where I would like to use boost parameter. I understand that I can use integers with the int_<> wrapper, but is there any trick or design pattern to allow template template's? The problem is that I have class templates such as an interpolator which will take in a type and a dimension size, and a variety of function objects of the same type. If I can't use template templates, I am not sure how to make the design sane. For example, right now I have something like: template<int Dimension, class T = double, template <int Dim2, class T> template Interpolator = cubic_spline> class DPP; I don't think I can write a free function to solve the instantiation difficulty since many of the types are only used internally and I couldn't use function template argument deduction. -Jesse

Implementing matrix_as_graph to convert a boost::numeric::ublas::matrix to a "graph"
by John Burgoon 29 Mar '09

29 Mar '09

Hi all, I wrote a small program in C++ using boost to read a neural network file (directional graph of a feedforward multilayer perceptron) into boost::numeric::ublas::matrix. The typical file size creates matrices of various sizes, anywhere from a 36x36 to a 130x130 matrix (of floats - edge weights between 0 and 1 to four sig figs). About half to two-thirds of the values are 0 in a typical graph, so I think of them as sparse. There are thousands of such files, so I have been really thrilled with the speed of boost. (I was doing this work with Perl last year. Ahem.) Now I want to implement the boost matrix_as_graph library so that I can convert my matrix into a graph and then implement various network metrics on the graph (such as betweenness_centrality.hpp). However, when I looked in the docs at http://www.boost.org/doc/libs/1_38_0/boost/graph/matrix_as_graph.hpp I was dismayed to find only a code listing: no explanation, no examples. I'm not the strongest C++ coder. Can someone point me to an example or tutorial of how to implement matrix_as_graph to turn a ublas::matrix into a graph? I think I could puzzle it out if I could find an example to emulate. I'll repay the community with a simple blog tutorial of how I did it, if someone can only help me get started. Thanks in advance, John -- John Burgoon Indiana University Bloomington, IN, USA -- >>Insight without implementation is worthless. Get to work.

MacOSX: problems linking with "universal binary" Boost and libstdc++-static.a
by FFT 28 Mar '09

28 Mar '09

I'm trying to link my "universal binary" program statically with both Boost and libstdc++-static.a to make the distribution easier, because, as I understand, /usr/lib/libstdc++.6.dylib isn't always there, especially, in versions prior to OSX-10.4 I can build Boost apparently successfully, but linking the regex example statically with libstdc++ causes errors. Perhaps someone here could point out what I'm doing wrong (if anything). Here's what I did to build "universal binary" Boost and compile the example (Btw, the documentation could use some clarity about the recipe): (1) Make sure "g++ --version" says i686-apple-darwin8-g++-4.0.1 (symlinks and PATH adjustments to avoid v3.3) (2) ../../bjam --prefix=~/local --build-dir=~/boost_build toolset=darwin link=static \ threading=multi architecture=combined stage install (I also tried adding runtime-link=static with similar results, see below) (3) g++ -static-libgcc -I ~/local/include/boost-1_38 example.cpp \ -o example /usr/lib/libstdc++-static.a ~/local/lib/libboost_regex-xgcc40-mt.a (I tried skipping /usr/lib/libstdc++-static.a, in which case the binary builds, but is linked with /usr/lib/libstdc++.6.dylib) The errors I get here take up many pages and start like this: /usr/libexec/gcc/i686-apple-darwin8/4.0.1/ld: warning multiple definitions of symbol std::codecvt<char, char, __mbstate_t>::~codecvt() /usr/lib/libstdc++-static.a(codecvt.o) private external definition of std::codecvt<char, char, __mbstate_t>::~codecvt()in section (__TEXT,__tex t) /usr/lib/gcc/i686-apple-darwin8/4.0.1/libstdc++.dylib(single module) definition of std::codecvt<char, char, __mbstate_t>::~codecvt() /usr/libexec/gcc/i686-apple-darwin8/4.0.1/ld: warning multiple definitions of symbol std::codecvt<char, char, __mbstate_t>::~codecvt() /usr/lib/libstdc++-static.a(codecvt.o) private external definition of std::codecvt<char, char, __mbstate_t>::~codecvt()in section (__TEXT,__tex t) /usr/lib/gcc/i686-apple-darwin8/4.0.1/libstdc++.dylib(single module) definition of std::codecvt<char, char, __mbstate_t>::~codecvt() When I use Boost built with "runtime-link=static", the errors look like this instead: /usr/libexec/gcc/i686-apple-darwin8/4.0.1/ld: warning multiple definitions of symbol std::codecvt<char, char, __mbstate_t>::~codecvt() /usr/lib/libstdc++-static.a(codecvt.o) private external definition of std::codecvt<char, char, __mbstate_t>::~codecvt()in section (__TEXT,__tex t) /usr/lib/gcc/i686-apple-darwin8/4.0.1/libstdc++.dylib(single module) definition of std::codecvt<char, char, __mbstate_t>::~codecvt() /usr/libexec/gcc/i686-apple-darwin8/4.0.1/ld: warning multiple definitions of symbol std::codecvt<char, char, __mbstate_t>::~codecvt() /usr/lib/libstdc++-static.a(codecvt.o) private external definition of std::codecvt<char, char, __mbstate_t>::~codecvt()in section (__TEXT,__tex t) Any suggestions?

Using boost across several different unix platforms
by Frank Meerkötter 28 Mar '09

28 Mar '09

Hello, i am currently looking into the possibility of using boost with a code base that needs to be compiled for a number of different unix platforms (AIX/HPUX/Solaris/Linux). Unfortunately i can't just use the gcc everywhere but i have to use the native compilers (XL/aCC/SunCC) instead. >From looking around the net i assume its not entirely impossible. There seems to be some (more or less official) effort from IBM and HP to have their compilers work with boost. My impression is that recent versions of XL and aCC are working quite OK with boost. I this impression correct? I am not so sure about the sunCC. I found a success story on the web but my general impression was that its not working so well? How are your experiences in that regard? In general, is someone using boost across a larger set (this set?) of compilers? What do you think? Doable with reasonable effort or hands off? Thanks for you insight. Frank

Trouble with regex
by Nathan Huesken 28 Mar '09

28 Mar '09

Hi, I have some trouble with regex. I have a string in this format: =?<encoding>?<Q or B>?<name>?= I want to extract the encoding, Q or B and name! I read the regex documentation and I try this: string mime_decode_field(string field) { boost::regex e("^=?([\x20-\x7E]*)?(Q|B)?([\x20-\x7E]*)?=$",boost::regex::perl|boost::regex::icase); boost::smatch what; if(boost::regex_match(field,what,e)) { //Now I expect <encoding> in what[1], <Q or B> in what[2] and <name> in what[3] } } But it is not as expected. what[2] and what[3] are empty, what[1] contains the whole string. What am I doing wrong? Thanks! nathan

FW: boost [regex] library icu building problems
by Alex Perry 28 Mar '09

28 Mar '09

Hi I hope this is the appropriate list for posting this message if not my apologies and could someone please redirect me. I seem to have a problem building the boost.regex library with icu support on windows with the msvc toolset (MS Visual Studio 2005 professional). Boost version is 1.35.0 (icu 3.8.1) I have built this using bjam with a command like:- bjam -sHAVE_ICU=1 --toolset=msvc stage This all seems to work perfectly well and the library boost_regex-vc80-mt-1_35.lib and .dll are created which work (very well) and give me the required unicode regex support. Unfortunately we have a memory leak in our application which I cant catch using valgrind on our linux version so am suspecting a problem with windows specific code. I was trying to recompile our application so that it used the debug version of the crt so that I could put in some memory tracking calls to find out what was wrong. However I have hit a snag with the boost library trying to do this. Compiling our application with _DEBUG, BOOST_REGEX_DYN_LINK defined and /MDd (debug crt ) boost swaps to using the boost_regex-vc80-mt-gd-1_35.lib library. I seem to have some difficulty building this version of the library with the optional icu support included. I did :- Bjam sHAVE_ICU=1 toolset=msvc build-type=complete stage But get an error in this case (I dont for build-type=minimal). The full output from bjam is below Im not quite sure what this error is meaning and what it is complaining about do I need to configure something in common properties here? - if someone with more experience of bjam than me could point me towards the problem I would be very grateful. The icuroot is pointing to where a copy of icu is living (d:/dependencies/icu/3.8.1/icu on this machine) and I have built a debug version of icu just in case this is what was wanted (using the provided allinone.sln shipped with the icu source) but doesnt appear to make any difference. Thanks in advance for your time Alex Perry Output from bjam:- bjam -sHAVE_ICU=1 --toolset=msvc --build-type=complete stage warning: Graph library does not contain optional GraphML reader. note: to enable GraphML support, set EXPAT_INCLUDE and EXPAT_LIBPATH to the note: directories containing the Expat headers and libraries, respectively. warning: skipping optional Message Passing Interface (MPI) library. note: to enable MPI support, add "using mpi ;" to user-config.jam. note: to suppress this message, pass "--without-mpi" to bjam. note: otherwise, you can safely ignore this message.

Error building the libraries for iPhone

Hello, I've recently added the Boost header libraries to my iPhone project, but I'd also like to use some of the compiled libraries. I've looked at the documentation and archives for the correct procedure, but I'm hitting a snag. I have added the following to the user-config.jam file: using darwin : 4.0.1~iphone : /Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/g++ -arch arm : <striper> : <architecture>arm <target-os>iphone <macosx-version>iphone-2.0 ; using darwin : 4.0.1~iphonesim : /Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/g++ : <striper> : <architecture>x86 <target-os>iphone <macosx-version>iphonesim-2.0 ; I then run bjam with the following parameters: bjam toolset=darwin architecture=arm target-os=iphone macosx-version=iphone-2.0 define=_LITTLE_ENDIAN Which fails on linking with the following message: darwin.link.dll bin.v2/libs/math/build/darwin-4.0.1~iphone/release/architecture-arm/macosx-version-iphone-2.0/target-os-iphone/threading-multi/libboost_math_c99-xgcc40-mt-1_38.so.1.38.0 lipo: /var/folders/1D/1DnUneWfGcCdxmoK6T0p2U+++TI/-Tmp-//ccpVFzN4.out and /var/folders/1D/1DnUneWfGcCdxmoK6T0p2U+++TI/-Tmp-//cciyh1K6.out have the same architectures (armv6) and can't be in the same fat output file "/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/g++" "-arch" "arm" -dynamiclib -Wl,-single_module -install_name "libboost_math_c99-xgcc40-mt-1_38.so.1.38.0" -o "bin.v2/libs/math/build/darwin-4.0.1~iphone/release/architecture-arm/macosx-version-iphone-2.0/target-os-iphone/threading-multi/libboost_math_c99-xgcc40-mt-1_38.so.1.38.0" "bin.v2/libs/math/build/darwin-4.0.1~iphone/release/architecture-arm/macosx-version-iphone-2.0/target-os-iphone/threading-multi/acosh.o" "bin.v2/libs/math/build/darwin-4.0.1~iphone/release/architecture-arm/macosx-version-iphone-2.0/target-os-iphone/threading-multi/asinh.o" "bin.v2/libs/math/build/darwin-4.0.1~iphone/release/architecture-arm/macosx-version-iphone-2.0/target-os-iphone/threading-multi/atanh.o" "bin.v2/libs/math/build/darwin-4.0.1~iphone/release/architecture-arm/macosx-version-iphone-2.0/target-os-iphone/threading-multi/cbrt.o" "bin.v2/libs/math/build/darwin-4.0.1~iphone/release/architecture-arm/macosx-version-iphone-2.0/target-os-iphone/threading-multi/copysign.o" "bin.v2/libs/math/build/darwin-4.0.1~iphone/release/architecture-arm/macosx-version-iphone-2.0/target-os-iphone/threading-multi/erfc.o" "bin.v2/libs/math/build/darwin-4.0.1~iphone/release/architecture-arm/macosx-version-iphone-2.0/target-os-iphone/threading-multi/erf.o" "bin.v2/libs/math/build/darwin-4.0.1~iphone/release/architecture-arm/macosx-version-iphone-2.0/target-os-iphone/threading-multi/expm1.o" "bin.v2/libs/math/build/darwin-4.0.1~iphone/release/architecture-arm/macosx-version-iphone-2.0/target-os-iphone/threading-multi/fmax.o" "bin.v2/libs/math/build/darwin-4.0.1~iphone/release/architecture-arm/macosx-version-iphone-2.0/target-os-iphone/threading-multi/fmin.o" "bin.v2/libs/math/build/darwin-4.0.1~iphone/release/architecture-arm/macosx-version-iphone-2.0/target-os-iphone/threading-multi/fpclassify.o" "bin.v2/libs/math/build/darwin-4.0.1~iphone/release/architecture-arm/macosx-version-iphone-2.0/target-os-iphone/threading-multi/hypot.o" "bin.v2/libs/math/build/darwin-4.0.1~iphone/release/architecture-arm/macosx-version-iphone-2.0/target-os-iphone/threading-multi/lgamma.o" "bin.v2/libs/math/build/darwin-4.0.1~iphone/release/architecture-arm/macosx-version-iphone-2.0/target-os-iphone/threading-multi/llround.o" "bin.v2/libs/math/build/darwin-4.0.1~iphone/release/architecture-arm/macosx-version-iphone-2.0/target-os-iphone/threading-multi/log1p.o" "bin.v2/libs/math/build/darwin-4.0.1~iphone/release/architecture-arm/macosx-version-iphone-2.0/target-os-iphone/threading-multi/lround.o" "bin.v2/libs/math/build/darwin-4.0.1~iphone/release/architecture-arm/macosx-version-iphone-2.0/target-os-iphone/threading-multi/nextafter.o" "bin.v2/libs/math/build/darwin-4.0.1~iphone/release/architecture-arm/macosx-version-iphone-2.0/target-os-iphone/threading-multi/nexttoward.o" "bin.v2/libs/math/build/darwin-4.0.1~iphone/release/architecture-arm/macosx-version-iphone-2.0/target-os-iphone/threading-multi/round.o" "bin.v2/libs/math/build/darwin-4.0.1~iphone/release/architecture-arm/macosx-version-iphone-2.0/target-os-iphone/threading-multi/tgamma.o" "bin.v2/libs/math/build/darwin-4.0.1~iphone/release/architecture-arm/macosx-version-iphone-2.0/target-os-iphone/threading-multi/trunc.o" -headerpad_max_install_names -Wl,-x -Wl,-dead_strip -no_dead_strip_inits_and_terms -isysroot /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS2.0.sdk -arch armv6 ...failed darwin.link.dll bin.v2/libs/math/build/darwin-4.0.1~iphone/release/architecture-arm/macosx-version-iphone-2.0/target-os-iphone/threading-multi/libboost_math_c99-xgcc40-mt-1_38.so.1.38.0...

What am I doing wrong? Without the full error message it's hard to say, but I suspect that \temp isn't being seen as a valid path, try ./temp if that's what you want, or else a full path. HTH, John.

[Phoenix] Compilation problem, help?
by Brett Gmoser 28 Mar '09

28 Mar '09

Hello everybody. With my current project I'm unfortunately still using Spirit 1.8.x and Phoenix. Having a bit of trouble figuring out the correct way to do something, hoping somebody can help! It actually compiles with the exception of some warnings from MSVC - the whole "A non-const reference may only be bound to an lvalue" warning I'm thinking it should be an easy fix probably just adding ref() or var() in the right places, I just can't figure out where. Here's some source code. The idea is to parse out an expression, and while doing so, store the operation type for later use at the end of the parsing, to avoid verbosity in having to do this every time I parse a different type of expression. /* Some notes: * - The closure variable 'oper_function' for assignment_statement is a Boost.Function specifying a function that returns expression_value, and takes two arguments of type expression_value. * - expression_value is a Boost.Variant. * - The form of variant's apply_visitor used is "delayed visitation", which returns just a functor with operator() which will do the actual visitation later. This works fine. * - assign_variable and lookup_variable are Phoenix functions. * - lhs and rhs closure variables are both expression_value's. * - I've tried using combinations of var(), val(), and ref() in as many different places as I could think of. * - The problem is with each of the oper function assignment lines, as well as the "assignment_statement.rhs)," line, which is line 671 in the warnings. * - Warnings from MSVC are below the code. */ assignment_statement = (as_lower_d[str_p("set") | str_p("define")] >> +white_space >> (name[assignment_statement.name = arg1]) >> longest_d[ // Allow just the assignment of an expression by itself without an operator. (+white_space>> expression[assignment_statement.rhs = arg1])[assignment_statement.oper_function = actors::deferred_binary_visit<actors::binary_op<cwb::wtl::detail::binary_operations::right_assign> >()] | // Allow all different types of assignment operators. (*white_space >> ( str_p("=") [assignment_statement.oper_function = boost::apply_visitor(actors::binary_op<cwb::wtl::detail::binary_operations::right_assign>())] |

[asio] need help with timer crash please
by bnv＠nc.rr.com 28 Mar '09

28 Mar '09

I incorrectly posted this to the boost developer's list, and am posting here to rectify that... I'm seeing two distinct crashes (gdb output below) on expiration of a deadline timer, and could use some help identifying possible reasons. The timer has not been deleted. The timer expired once before and was later rescheduled using expires_from_now() and async_wait(). The timer is only accessed by threads in io_service::run(), and is protected by a mutex. Form the gdb output, I'm guessing the timer is being removed on expiration and the internal structures have somehow been trashed. Any pointers to possible explanations would be appreciated. crash 1... > Program received signal SIGSEGV, Segmentation fault. > [Switching to thread 3500.0x83c] > 0x5ae9a800 in ??

[Q] extendig lexical cast with custom classes
by V S P 28 Mar '09

28 Mar '09

I developed a class cmoney_t and would like to use it uniformly with all the other datatypes I am using One of the things I would like to use is boost::lexical_cast<std::string> (const cmoney_t& in) However, when I simply just try to specialize the tempalte function lexical_cast it tells me that I cannot define that function within my namepsace (I have my own namespace) so wanted to know if there is a way to extend lexical_cast to support my custom classes thanks in advance -- V S P toreason(a)fastmail.fm -- http://www.fastmail.fm - Send your email first class
