Looking for ideas for hacking of doxygen comments to make decent metafunction documentation. Anyone have some experience with this?

Hi there, on the page http://www.boost.org/doc/libs/1_37_0/libs/math/doc/sf_and_dist/html/math_to… Shouldn't be the string "boost::gamma_distribution<>" be "boost::math::gamma_distribution<>"? Christian

[math] gamma function
by Christian Henning 05 Nov '08

05 Nov '08

Hi there, quick question. I have a gamma function with a shape and scale. To calculate the CDF for a specific probability is easy. BUT, can I somehow do the inverse? I mean calculate the probability from a given CDF? Thanks, Christian

shared_ptr and Visual Studio 2008 Express SP1
by Sergey Sadovnikov 05 Nov '08

05 Nov '08

Hello All, During migrating my project under new development environment I face out following issue: ambiguous unqualified 'shared_ptr' name resolution. For example in .cpp files I using several usings such as: using namespace std; using namespace std::tr1; using namespace boost; In source code I have something like this: shared_ptr<SomeType> var = /*...*/; And for each such line I have an error: error C2872: 'shared_ptr' : ambiguous symbol could be 'c:\program files\microsoft visual studio 9.0\vc\include\memory(1392) : std::tr1::shared_ptr' or 'c:\program files\microsoft visual studio 9.0\vc\include\memory(1392) : std::tr1::shared_ptr' or 'p:\projects\common\boost_1.36.0\boost\shared_ptr.hpp(165) : boost::shared_ptr' What I have to do to avoid this errors for boost 1.36 except explicit share_ptr qualification? Explicit including of "boost/shared_ptr" or "memory" I already put into #ifdef/#endif braces. But this didn't help. -- Best Regards, Sergey mailto:flex_ferrum@artberg.ru

[boost 1.36]: Problems with bjam option --buildid
by Daniel Krügler 05 Nov '08

05 Nov '08

Hello, a colleague of mine currently checks whether transition to boost 1.36 (or upcoming 1.37) would be feasible for us. Still being on 1.33.1, we manipulated the bjam files to realize something that we hope can now be done with the build option --buildid using the *non-manipulated* bjam files. A recent test using the command line bjam --build-dir=XX --buildid=asdf --toolset=msvc --build-type=complete stage where XX corresponds to a valid path causes a quick bjam build error (but removing the part " --buildid=asdf" works fine), as shown below. Let me add that the used bjam.exe was created based on the sources provided by the very same boost 1.36 (build.bat). Does anyone have an idea what's going wrong here?

problems with boost in eclipse
by Z. S. O. 05 Nov '08

05 Nov '08

Hello -- I extracted Boost.Filesystem using the BCP tool, so I could add it to my Xcode project without having to precompile. It worked great! Only problem is that I decided to move my project to Eclipse. Now, when I compile, I keep getting the following error: Description: 'BOOST_UTF8_BEGIN_NAMESPACE' does not name a type Resource: boost/libs/detail/utf8_codecvt_facet.cpp Anyone know how I might try to get this to work in Eclipse? Thank you so much in advance.

[asio] question about binding member function as WaitHandler
by eburkitt＠gmail.com 05 Nov '08

05 Nov '08

The documentation's example 4 uses boost::bind to create a handler for deadline_timer::async_wait(). The function bound, printer::print(), takes no parameter and the code compiles and works fine. I tried modifying the example so that, instead of creating a new, temporary function object in place for each call to async_wait(), it creates a single boost::function object as a data member in the ctor, which is then passed in each call. Using MSVS 2005 and boost 1.37 I found that I had to add a boost::system::error_code& parameter to print() in order to get it to compile. Here is my modified printer class, with both the non-working (version 1) and working (version 2) code to, I hope, make this clearer. class printer { public: printer(boost::asio::io_service& io) : timer_(io, boost::posix_time::seconds(1)), // timer_fn_(boost::bind(&printer::print, this)), //**version 1 timer_fn_(boost::bind(&printer::print, this, _1)), //**version 2 count_(0) { timer_.async_wait(timer_fn_); } ~printer() { std::cout << "Final count is " << count_ << "\n"; } //void print() //**version 1 void print(const boost::system::error_code& /*e*/) //**version 2 { if (count_ < 5) { std::cout << count_ << "\n"; ++count_; timer_.expires_at(timer_.expires_at() + boost::posix_time::seconds(1)); timer_.async_wait(timer_fn_); } } private: //typedef boost::function<void(void)> timer_fn_type; //**version 1 typedef boost::function<void(const boost::system::error_code&)> timer_fn_type; //**version 2 boost::asio::deadline_timer timer_; timer_fn_type timer_fn_; int count_; }; The error report for version 1 is "term does not evaluate to a function taking 1 arguments" at boost/asio/detail/bind_handler.hpp line 39. I can see why version 1 won't compile. What I don't understand is why the original example, with its in-place function objects, does. Thanks for any insight. -evan

boost 1.37.0 problem with mpl
by Andrew Maclean 05 Nov '08

05 Nov '08

I successfully built release/debug versions and installed boost-1_37 under Windows Vista, Visual C++ 9.0 SP1. I use the following command: bjam --toolset=msvc --build-type=complete stage install However when I am using UBLAS, I get the following error: Error 1 fatal error C1083: Cannot open include file: 'boost/mpl/vector/aux_/preprocessed/plain/vector20.hpp': No such file or directory C:\Boost\include\boost-1_37\boost\mpl\vector\aux_\include_preprocessed.hpp 49 I checked 'boost/mpl/vector/aux_/preprocessed/plain/ and here is a listing of the files there: Directory of C:\Boost\include\boost-1_37\boost\mpl\vector\aux_\preprocessed\plain 05/11/2008 14:27 <DIR> . 05/11/2008 14:27 <DIR> .. 02/09/2004 11:41 19,378 vector10.hpp 28/11/2004 01:50 3,415 vector10_c.hpp 28/11/2004 01:50 6,556 vector20_c.hpp 02/09/2004 11:41 52,729 vector30.hpp 28/11/2004 01:50 9,747 vector30_c.hpp 02/09/2004 11:41 69,549 vector40.hpp 28/11/2004 01:50 12,937 vector40_c.hpp 02/09/2004 11:41 86,369 vector50.hpp 28/11/2004 01:50 16,136 vector50_c.hpp 10 File(s) 276,816 bytes As you can see, vector20.hpp is missing. Is tthis a legitimate problem or have I not built something correctly? Thanks for any help Andrew -- ___________________________________________ Andrew J. P.
