boost serialize, exception "eaten" up...
by Robert Bielik 23 Feb '14

23 Feb '14

Hi all, I'm trying to make a deserialization user cancellable, and I thought, hey, if I throw an exception in a progress handler (used when reading chars from input stream), that would propagate through the load hieararchy and I can catch it at top level... Nope... it gets caught in iostream (VS2012, row 776) :( , so the _CATCH_IO_END is probably a catch(...). Not very nice, and quite counter-productive if you ask me. Any ideas how to get that exception out ? Regards /Robert

Build errors trying to build Boost with mingw-w64
by Da-Huntha 22 Feb '14

22 Feb '14

Hey all, I've been trying to build all Boost libraries with mingw-w64 on Windows 8 but some fail. I'm trying to build a 32bit windows release build. The following errors are an excerpt of all the build errors: >d:\win-builds-32\i686-w64-mingw32\include\dvec.h: In function 'F64vec2 IntToF64vec2(const >F64vec2&, int)': >d:\win-builds-32\i686-w64-mingw32\include\dvec.h:840:80: error: '_mm_cvtsi32_sd' was not declared in this scope > inline F64vec2 IntToF64vec2(const F64vec2 &a,int b) { return _mm_cvtsi32_sd(a,b >); } > >^ >In file included from ./boost/system/system_error.hpp:14:0, > from ./boost/thread/exceptions.hpp:22, The build is invoked with: >set PATH=%MINGW_HOME%\bin;%WINDDK_HOME%\7600.16385.1\bin\x86 >bjam toolset=gcc variant=release threading=multi link=static address-model=32 Does anyone understand why these errors are given? Am I missing some configuration?

[mpl][type_traits] Transforming to common type
by Bjorn Reese 22 Feb '14

22 Feb '14

Given a type T, I am trying to transform a type list into another containing the common type between T and the individual types in the type list. When I compile the example below, I get the following error: /usr/local/include/boost/type_traits/common_type.hpp:111:42: error: incompatible operand types ('mpl_::arg<1>' and 'int') typedef decltype(declval<bool>() ? declval<T>() : declval<U>()) type; ^ ~~~~~~~~~~~~ ~~~~~~~~~~~~ It appears that the placeholder is not expanded to its actual type. If I use, say, decay<> instead of common_type<>, the example works just fine. Does anybody know how I can make it work? Example code: #include <boost/mpl/vector.hpp> #include <boost/mpl/transform.hpp> #include <boost/type_traits/common_type.hpp> int main() { typedef boost::mpl::vector<int, double> sequence_types; typedef boost::mpl::transform< sequence_types, // This is causing the problem boost::common_type<boost::mpl::_1, int>::type >::type transformed_types; return 0; }

[geometry] boost 1.55, VC++2013 update 1 Build fail
by 乔志强 21 Feb '14

21 Feb '14

I create a Visual Studio 2013 update 1 VC++ Win32 Console Application project, and copy the example from boost_1_55_0\libs\geometry\doc\html\geometry\spatial_indexes\rtree_examples\quick_start.html to a file(delete all codes first), set Precompiled Headers to Not Using Precompiled Headers, then build. But build failed. I change the platform toolset from Visual Studio 2013 (v120) to Visual Studio 2010 (v100), then build successfully. Is it a bug ?

[interprocess] Shared memory object
by Patrick Steele 21 Feb '14

21 Feb '14

Hi, can anyone tell me if there is a performance or other difference between boost::interprocess::shared_memory_object and boost::interprocess::windows_shared_memory? With the version of boost we were using back in 2011 ( boost 1.48 ), we found that windows_shared_memory operated faster than shared_memory_object when transporting around 10MB of data. Is this still the case? Thanks, Patrick

Gsoc
by Anulesh Tiwari 21 Feb '14

21 Feb '14

I've been looking at the various projects and the previous years project . I came across the boost.ublas project that was offered last year . This project seems very cool . Is the project going to be offered again ? The idea of adding additional protocols or modifying existing protocols sounds fun . There will be very likely a project proposal for the boost.ublas project, content will be very similar :) I would love to get a better feel about the entire boost project . Any pointers on how to do the same would be very helpful.

Build problems with 64-bit VC12 (MSVS2013)
by Craig Henderson 21 Feb '14

21 Feb '14

Hi all, I am having trouble building Boost 1.55 for x64 using VC12. 32-bit builds without error, but 64-bit fails. All of the errors are boost/archive/iterators/transform_width.hpp(151) : error C2039: 'min' : is not a member of 'std' and repeats a lot I added #include <algorithm> to the beginning of the transform_width.hpp header file, and the build now completes without error. However, my app has two linker errors linking with libboost_system-vc120-mt-1_55.lib features.obj : error LNK2019: unresolved external symbol "class boost::system::error_category const & __cdecl boost::system::system_category(void)" (?system_category@system@boost@ @YAAEBVerror_category@12@XZ) referenced in function "public: __cdecl boost::system::error_code::error_code(void)" (??0error_code@system@boost@ @QEAA@XZ) features.obj : error LNK2019: unresolved external symbol "class boost::system::error_category const & __cdecl boost::system::generic_category(void)" (?generic_category@system@boost@ @YAAEBVerror_category@12@XZ) referenced in function "void __cdecl boost::system::`dynamic initializer for 'errno_ecat''(void)" (??__Eerrno_ecat@system@boost@@YAXXZ) Again, the 32 bit builds and links Ok. I'm thinking that as the problematic file in Boost in is an 'archive' directory, perhaps the wrong include file is being picked up? But I can't find the difference in 32/64 configurations to find the cause. Is this a known problem? Any suggestions how to diagnose or (preferably!) fix this? Many thanks Craig

Where is BOOST_TEST - the universal testing tool

20 Feb '14

Hi, I read here<http://boost.2283326.n4.nabble.com/test-BOOST-TEST-universal-testing-tool-t…>and here <http://lists.boost.org/Archives/boost/2013/09/206202.php>about BOOST_TEST - the universal testing tool. Where can I find it? Is it still not part of the library? Thanks, Adi

template trick
by gast128 19 Feb '14

19 Feb '14

I recently watched Stephen Lavavej's excellent channel9 video 'Core C++, 2 of n' in which he described a nice trick to stop template argument deduction: template <typename T> void (T t1, typename std::identity<T>::type t2) { } Browsing the internet for a similar problem, I recently discovered that Peter Dimov already described this trick in 2002 in 'Template function type inference with references' comp.lang.c++.moderated. Boost is more for the libraries, but could it also reserve some space for documenting these template tricks?

Should boost libs be rebuilt after applying patch?
by qplace 19 Feb '14

19 Feb '14

boost 1.55 I had to apply the patch defined in Ticket #9369 to the boost source file. I did it after libraries were built. Should I now rebuild the libraries again?
