Hi, I need some help on building boost. I am trying to build boost 1.32.0 with dev-cpp. I am employing the command line: bjam "-sTOOLS=mingw" "--with-python-root=C:\Python24" "-sMINGW_ROOT_DIRECTORY=C:\Program Files\Dev-Cpp" install And I am getting the errors: D:\katti\programasOutros\bibliotecasC++\boost\boost_1_32_0>bjam "-sTOOLS=mingw" "--with-python-root=C:\Python24" "-sMINGW_ROOT_DIRECTORY=C:\Program Files\Dev-Cpp" install ...found 11553 targets... ...updating 1601 targets... gcc-C++-action bin\boost\libs\date_time\build\boost_date_time.dll\mingw\debug\gr eg_month.obj In file included from D:/katti/programasOutros/bibliotecasC++/boost/boost_1_32_0 /boost/config.hpp:40, from D:/katti/programasOutros/bibliotecasC++/boost/boost_1_32_0 /boost/date_time/constrained_value.hpp:12, from D:/katti/programasOutros/bibliotecasC++/boost/boost_1_32_0 /boost/date_time/gregorian/greg_month.hpp:12, from D:/katti/programasOutros/bibliotecasC++/boost/boost_1_32_0 /libs/date_time/src/gregorian/greg_month.cpp:14: D:/katti/programasOutros/bibliotecasC++/boost/boost_1_32_0/boost/config/select_s tdlib_config.hpp:20:19: utility: No such file or directory In file included from D:/katti/programasOutros/bibliotecasC++/boost/boost_1_32_0 /boost/shared_ptr.hpp:26, from D:/katti/programasOutros/bibliotecasC++/boost/boost_1_32_0 /boost/date_time/gregorian/greg_month.hpp:14, from D:/katti/programasOutros/bibliotecasC++/boost/boost_1_32_0 /libs/date_time/src/gregorian/greg_month.cpp:14: D:/katti/programasOutros/bibliotecasC++/boost/boost_1_32_0/boost/detail/shared_c ount.hpp:34:61: memory: No such file or directory D:/katti/programasOutros/bibliotecasC++/boost/boost_1_32_0/boost/detail/shared_c ount.hpp:35:41: functional: No such file or directory D:/katti/programasOutros/bibliotecasC++/boost/boost_1_32_0/boost/detail/shared_c ount.hpp:36:46: exception: No such file or directory D:/katti/programasOutros/bibliotecasC++/boost/boost_1_32_0/boost/detail/shared_c ount.hpp:37:46: new: No such file or directory D:/katti/programasOutros/bibliotecasC++/boost/boost_1_32_0/boost/detail/shared_c ount.hpp:38:61: typeinfo: No such file or directory ....

Boost Python installation Windows XP+Visual C++ 7.1
by Nguyen Xuan Son 07 Dec '04

Hi, My problem is the following 1/ I install Python 2.4 at D:\Programs\Python24 using the binary file from www.python.org 2/ following the document from the boost.org I type the command >bjam "-sTOOLS=vc-7_1 --with-python-root=D:\Programs\Python24" stage But I receive the following error > --with-python-root=D:\Programs\Python24-tools.jam: Invalid argument I think I do something wrong here. If I use the simple command >bjam "-sTOOLS=vc-7_1 " stage I get the message: >skipping Boost.Python ..... Can someone show me how can I install Boost.Python correctly? Thanks Xuan Son

------------------------------ Toon Knapen wrote: This is again the old include-policy problem. Previously the headers of ublas were not self-contained. This has been fixed but only on a branch (and thus not in the 1.32 release). I plan to merge this branch also to the HEAD. For now, you just need to include storage.hpp before you include lu.hpp. In that case, on line 24 of lu.hpp will it recognise unbounded_array (which is defined in storage.hpp) ------------------------------ Toon, Thank you for the response! I was unaware of this include-policy problem. Will you be merging this code soon? I will try to look for your email about this merge. I tried fixing this within lu.hpp and it appeared as if errors were being added recursively so I gave up and posted the question. Since adding #include<storage.hpp> to lu.hpp didn't fix the problem, should I expect to have to include additional files to my code to fix errors in files such as storage.hpp? Thanks again for your time and effort, - dan elliott

It's a constrained unsigned short with a min of 1400 & a max of 10000. The as_number function was added to greg_month and greg_day to ease math operations. Since greg_year is a constrained value math simply "works", as does operator<<. Is there a specific reason why you'd like one added to greg_year? Thx, Bart

Depnding on how you're compiling your code, this may explain the linker error. I rebuilt (and downloaded 1.32 along the way) and now libboost_regex-gcc.so is a hard link to libboost_regex-gcc-1_32.so.1.32.0. I don't believe it was before (could be wrong) Anyway, compiling with the generic name now works great, thanx.

[Review Results] Named Parameters Library
by Doug Gregor 06 Dec '04

06 Dec '04

The Named Parameters Library has been accepted into Boost. Congratulations to the authors, David Abrahams and Daniel Wallin. The vast majority of reviews were positive, although most reviewers requested additional documentation. Here is a list of the most important/commonly-requested changes or additions to the library: - More documentation! Specifically, + Automatic overload generation should go into the tutorial + Document operator, + Performance data (what's the cost?) + Reference section + "Best practices" section. - Add a metafunction for getting the type of a parameter, e.g., param_type<Params, width_t>::type. - Add test cases for the automatic overload generation macros. - Fix the BOOST_NAMED_PARAMS_MAX_ARITY bug; Cromwell Enage provided a solution.

Q: Stopping threads (Win32) or... the mysterious case of the thread with split personality
by Dan Dimerman 06 Dec '04

06 Dec '04

Hello, I would like to ask the group if you know of an efficient and clean way to stop a thread. What I've been using till now was a while loop in the function operator()() given to the boost::thread when created, whose condition was a boolean data member. This boolean was the means to stop the thread, such that when it was turned off, the child thread would exit the while loop and join the main thread. I am seeing now that this data member is being held twice (one copy for the main thread and one copy for the child thread) and there's no synch between the two copies; so when the main thread turns it off / false, the child thread goes on (since its copy is still on / true) and hell breaks loose. I am using VC7 in debug mode, so I started looking for some kind of flag/optimization I might be inadvertently using that makes data members into registers (thus explaining the copies), but couldn't find anything of the sort. Any help will be greatly appreciated... Dan --- Outgoing mail is certified Virus Free.

determining a sensible result type for a function

Hi! Let's consider this function object: template<typename TLeft, typename TRight> struct mixed_plus : public binary_function<TLeft, TRight, TLeft> { result_type operator() (first_argument_type left, second_argument_type right) const { return left + right; } };
