[math] Undefined reference to promote_args
by Florian Lindner 18 Aug '16

18 Aug '16

Hello, when compiling a file that uses float_distance from #include <boost/math/special_functions/relative_difference.hpp> I get a linking error: undefined reference to `boost::math::tools::promote_args<double, double, float, float, float, float>::type boost::math::float_distance<double, double>(double const&, double const&)' I try to add all boost_math libs I could find, but none helped: -lboost_system -lboost_filesystem -lboost_math_tr1 -lboost_math_c99 -lboost_math_c99 Since float_distance is not a C99 / TR1 function, should'nt boost.math work as header only? What is the problem here? Thanks, Florian

Custom build of Python3 not picked up by Boost.Build
by Matthieu Brucher 17 Aug '16

17 Aug '16

Hi, As I need a build of Python3 compatible with VS2012, I built it from scratch and installed it in a _INSTALL folder, following a tutorial online. Now, I want to use that Python3 with Boost.Python, so I did this in my use-config.jam: using python : 3.4 : D:/Tools/Python-3.4.5/_INSTALL/python.exe : D:/Tools/Python-3.4.5/_INSTALL/include : D:/Tools/Python-3.4.5/_INSTALL/libs ; And then: .\bootstrap.bat --with-python=D:\Tools\Python-3.4.5\_INSTALL --with-python-version=3.4 --python-buildid=3 which failed. The includes are found properly, but the link is floawed: LINK : fatal error LNK1104: cannot open file 'python34.lib' The library is in D:/Tools/Python-3.4.5/_INSTALL/libs, but could not be found according to the log. Also, something strange: D:\Tools\boost_1_60_0\tools\build\src\engine>.\bootstrap\jam0 -f build.jam --toolset=vc14 "--toolset-root=C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\Tools\..\..\VC\ " --with-python=D:\Tools\Python-3.4.5\_INSTALL --with-python-version=3.4 --python-buildid=3 The retrieved toolset is wrong, as explicitely asked for VS2012 aka 11.0 int he user-config.jam and I'm running it from a VS2012 x64 native tools command prompt. Couldn't find any help online, so the best is to ask the Boost community!

[MSM] templated state machine generates many errors when a state is derived from msm::front::exit_pseudo_state<event>

I just wanted to check that there was not something obvious I am doing wrong here: relevant parts: the exit state (defined outside the state machine) struct QueryGood { QueryGood(query_complete const&

Boost Units initialize quantity with signaling NaN
by Belcourt, Kenneth 13 Aug '16

13 Aug '16

Hi, I’m trying to find a way to initialize a Boost Unit with a signaling NaN, not just a NaN with the signal cleared. It seems that the only way to initialize a quantity is by multiplying by the unit, and that multiplication clears the signal on the NaN. I know I can just modify the quantity.hpp header and initialize the default constructor val_ member with the signaling NaN, but I was hoping for a cleaner solution. Here’s an example (typed in by hand, not tested): const double s_nan = std::numeric_limits<double>::signaling_NaN(); typedef quantity<si::acceleration, double> acceleration_t; BOOST_UNITS_STATIC_CONSTANT(acceleration_u, acceleration); acceleration_t a(s_nan * acceleration_u); // <— this clears the signal on the NaN Has anyone encountered this or know of a more elegant solution than modifying the quantity.hpp header? — Noel

[Wave] Wave samples and driver utility not building?
by Michael Young 12 Aug '16

12 Aug '16

I have just built boost_1_61_0; I am particularly interested in Boost.Wave at this time. This is my first attempt to build any boost library, or boost in its entirety (all libs). I read and followed the build instructions from the web site, with slight modifications for my environment / purposes: bootstrap.sh 2>&1 | tee build_boost_log.txt sudo ./b2 install 2>&1 | tee -a build_boost_log.txt When it completes, I get the libboost_*.a and .so files in /usr/local/lib, and the source is installed at /usr/local/include/boost, as expected. I do get "...failed updating 58 targets..." in the build output, but my understanding is that's OK - I didn't install optional items like ICU and such. The problem is that I can't find the wave driver (or other sample) utility anywhere. Moreover, when I look at the build log, there is no indication that any of these are being built (even attempted). So I'm wondering if there's a build step / option that I am missing (and/or perhaps I need one of the "optional" 3rd party packages installed?). BTW - I'm building in Ubuntu 14.04 ARM (crouton chroot on Chromebook), with gcc/g++ 4.8.4. I didn't see any indication of any environment problems in the build log.

[Asio] Making custom std::streambuf for async_read
by knarks＠online.de 11 Aug '16

11 Aug '16

At the moment I'm using async_read with boost::asio::streambuf and this works fine but I need a custom stream where every invoke to async_read appends the data to my stream. The stream should be based on std::streambuf because I want to keep the asio interface hidden to the user. My first idea was to search for the problem and I ended up with reading about MutableBufferSequence but I don't know if this is the right way and how to implement this in my streambuf object. Any help is higly appreciated.

Re: [Boost-users] [spirit][karma] multiprecision modf
by Daniel Brake 08 Aug '16

08 Aug '16

Thanks for the reply, John. I think for now I will simply use the .str() method for mpfr_float, since my policies for printing numbers need the entire number (or really, some portion of the number which is known at runtime, but not necessarily at compile time). Any help from the Boost.Spirit people on connecting Boost.Multiprecision variable-precision types would be swell. I am happy to help with this. I already use Spirit.Qi for parsing, and love it, so really want to be able to use Karma in full, as well.

Sir, I gave the following includes #include <boost/serialization/array.hpp> #include <boost/array.hpp> I know boost::array exists,but does boost::serialization::array exist?Because in the namespace serialization in the boost/serialization/array.hpp, I could not find such a template. namespace boost { namespace serialization { // traits to specify whether to use an optimized array serialization template <class Archive> struct use_array_optimization : boost::mpl::always<boost::mpl::false_> {}; template<class T> class array_wrapper : public wrapper_traits<const array_wrapper< T > > { private: array_wrapper & operator=(const array_wrapper & rhs); public: // note: I would like to make the copy constructor private but this breaks // make_array.

Any help with this one would be greatly appreciated. It feels beyond my diagnosis. It feels to me like I might should feed mpfr_float into Fusion to adapt it, so I can use the type directly with Karma. Here's the generator code so far: template <typename Num> struct BertiniNumPolicy : public karma::real_policies<Num> { // we want the numbers always to be in scientific format static int floatfield(Num n) { return std::ios_base::scientific; } static unsigned int precision(Num) { return std::numeric_limits<Num>::max_digits10; } }; template<> struct BertiniNumPolicy<mpfr_float> : public karma::real_policies<mpfr_float> { // we want the numbers always to be in scientific format static int floatfield(mpfr_float n) { return std::ios_base::scientific; } static unsigned int precision(mpfr_float const& x) { return x.precision(); } }; template<typename Num> using FullPrec = boost::spirit::karma::real_generator<Num, BertiniNumPolicy<Num> >; FullPrec<double> const full_prec_d = FullPrec<double>(); FullPrec<mpfr_float> const full_prec_mp = FullPrec<mpfr_float>(); template <typename OutputIterator> static bool generate(OutputIterator sink, mpfr_float const& c) { using boost::spirit::karma::generate; return generate(sink, // Begin grammar ( full_prec_mp ), // End grammar c // Data to output ); } As a last question, I am unsure about the use of the a function parameter in my specialization BertiniNumPolicy<mpfr_float>, particularly the precision(mpfr_float) function. In the documentation and examples I have seen for specializations, this function doesn't use the argument. Is it ok that it does, that it checks the actual precision of x??? See above code. An alternate method for me might be to just use the str() method provided by the number<...> from Multiprecision, but it seems like since this type is numeric, I'd like to be able to generate using the numeric generators from Karma.

multiprecision modf
by Daniel Brake 03 Aug '16

03 Aug '16

Hi Boost, Does Boost.Multiprecision provide modf for floating point types? I need it for generating with Karma, unless the fact that mpfr_float with variable precision not having numeric_traits might get in the way. Thanks for any help. Error message follows.

boost::serialization::array for Orocos RTT
by Sambeet Panigrahi 02 Aug '16

02 Aug '16

Sir, I work on Orocos Real Time toolkit.Thhe project uses a boost::serialization::array however in the boost 1.44 I use there is no such header.Can you please tell me whether this header is really a part of Boost now? If no what can I use instead of that? I am posting the relevant build errors from RTT for a clearer idea: In file included from /home/sambeet/rtt-master/rtt/internal/DataSourceTypeInfo.hpp:44:0, from /home/sambeet/rtt-master/rtt/internal/DataSource.inl:5, from /home/sambeet/rtt-master/rtt/internal/DataSource.hpp:237, from /home/sambeet/rtt-master/rtt/OperationInterface.hpp:48, from /home/sambeet/rtt-master/rtt/OperationInterface.cpp:39: /home/sambeet/rtt-master/rtt/internal/../types/carray.hpp:99:48: error: expected ‘)’ before ‘<’ token carray( boost::serialization::array<T> const& orig) ^ /home/sambeet/rtt-master/rtt/internal/../types/carray.hpp:165:41: error: ‘array’ is not a member of ‘boost::serialization’ const carray<T>& operator=( boost::serialization::array<OtherT> const& orig ) { ^ /home/sambeet/rtt-master/rtt/internal/../types/carray.hpp:165:41: note: suggested alternative: In file included from /usr/include/boost/serialization/array.hpp:151:0, from /home/sambeet/rtt-master/rtt/internal/../types/carray.hpp:42, from /home/sambeet/rtt-master/rtt/internal/DataSourceTypeInfo.hpp:44, from /home/sambeet/rtt-master/rtt/internal/DataSource.inl:5, from /home/sambeet/rtt-master/rtt/internal/DataSource.hpp:237, from /home/sambeet/rtt-master/rtt/OperationInterface.hpp:48, from /home/sambeet/rtt-master/rtt/OperationInterface.cpp:39: /usr/include/boost/array.hpp:60:11: note: ‘boost::array’ class array { ^ In file included from /home/sambeet/rtt-master/rtt/internal/DataSourceTypeInfo.hpp:44:0, from /home/sambeet/rtt-master/rtt/internal/DataSource.inl:5, from /home/sambeet/rtt-master/rtt/internal/DataSource.hpp:237, from /home/sambeet/rtt-master/rtt/OperationInterface.hpp:48, from /home/sambeet/rtt-master/rtt/OperationInterface.cpp:39: /home/sambeet/rtt-master/rtt/internal/../types/carray.hpp:165:75: error: expected primary-expression before ‘>’ token const carray<T>& operator=( boost::serialization::array<OtherT> const& orig ) { ^ /home/sambeet/rtt-master/rtt/internal/../types/carray.hpp:165:77: error: expected primary-expression before ‘const’ const carray<T>& operator=( boost::serialization::array<OtherT> const& orig ) { ^ /home/sambeet/rtt-master/rtt/internal/../types/carray.hpp:165:89: error: declaration of ‘operator=’ as non-function const carray<T>& operator=( boost::serialization::array<OtherT> const& orig ) { ^ make[2]: *** [rtt/CMakeFiles/orocos-rtt-gnulinux_dynamic.dir/OperationInterface.cpp.o] Error 1 make[1]: *** [rtt/CMakeFiles/orocos-rtt-gnulinux_dynamic.dir/all] Error 2 make: *** [all] Error 2 Regards Sambeet

Windows installation issues
by Alexander Carôt 01 Aug '16

01 Aug '16

Hi all, after having switched from OSX and Linux to Windows 10 I have issues compiling boost (1.61)with the MinGW compiler. The very first step fails: bootstrap.bat mingw results in not finding a right path, denying access and aborting the installation. So far I only found this article: https://andres.jaimes.net/698/use-c-with-mingw-and-netbeans-in-windows/ but it does not contain further info how (and where) to add additional info (I added c:\MinGW\bin to my PATH but it didn’t help). Any help appreciated, thanks in advance Alex --
