My boost was built with VC++ 9. And when add #define BOOST_NO_RVALUE_REFERENCES, other errors arose - actually, VS2008 supports rvalue references. Best regards,Max

hi, I'm newbie. the only one thing that I wanted to ask is building boost 64bit on aix6.1. I try it a number of times. and I failed building 64bit boost objects. It built only 32bit objects. I used this option, address-model=64. but it didn't work. would you tell me how to build boost 64bit on aix6.1 thanks read this msg. 주식회사 테미 임영운(Yeong-woon Im) 305-764 대전광역시 유성구 대학로99 충남대학교 산학연교육연구관 807호 #807, TBI Center, Chungnam University 99 Daehak-ro, Yuseong-gu, Deajeon, 305-764 Korea Home URL : http://www.temee.co.kr Tel : 042-824-7014 Fax : 042-824-7015 Mobile : 010-6266-9960

Unable to build old project using boost

Hi guys, This must be a trivial question, but I just couldn't sort it out. I'm compiling a old project which used to work fine. But now I received a bunch of errors (this is not a surprise because the project have a lot of other dependencies and I'm in the way of setting them up) with the first one as: c:\lib\boost_1_49_0\boost\type_traits\add_lvalue_reference.hpp(19) : error C2143: syntax error : missing ',' before '&&' I'm using Win 7 SP1 + VS 2008 with SP + boost 1.49.0 (I'm using this because I previous used this.

Newbie question: Example of a simple grammar and autocompletion?
by Vidya Setlur 10 Apr '15

10 Apr '15

Hi all, I'm trying to understand how the Boost spirit parsers work. Could anyone show me a simple example of a grammar, and how autocompletion can be enabled if the input matches a particular rule in the grammar template? Thanks!

FW: [phoenix][spirit][qi][utility] Version 1.57 of Boost Phoenix breaks when used with MSVC 2010 compiler?
by Andrew Nordquist 09 Apr '15

09 Apr '15

Hello, Boost Phoenix folks - I sent the message below a few weeks ago, looking for assistance in getting Boost 1.57 to compile with MSVC 2010 and my complex C++ code. I have yet to receive a response. Perhaps it was misdirected; maybe I need to send this to [spirit] or [qi] or [utility] or ...? In the weeks since I sent this, I have not exactly been idle on the subject. I have installed Boost 1.54, 1.55, and 1.56 on my computer. I have in turn tried each version by just switching out the include and linker locations. So far, I have found out that 1.53, 1.54, and 1.55 compile successfully. However, switching to 1.56 or 1.57, there is no success. The diagnostics for both versions are similar, regarding too few template arguments for a call to [utility] result_of.hpp that <boost/phoenix/core/detail/preprocessed/function_eval_10.hpp> is making. Does anyone have any ideas or suggestions on how to make Boost 1.57 work with MSVC 2010 and my code? I would be grateful. Thank you, /Andrew Nordquist From: Andrew Nordquist Sent: Thursday, March 19, 2015 12:35 PM To: 'boost-users(a)lists.boost.org' Subject: [Phoenix] Version 1.57 of Phoenix breaks when used with MSVC 2010 compiler? Hello, folks - I must be doing something wrong, but I can't figure it out. I/we have been using Boost in our 20,000+ lines of C++ code for a few years now. We started with 1.43, went smoothly to 1.53, and although it was bumpy going from MSVC 2008 to MSVC 2010, we are there now. We are now using MSVC 2010 and Boost 1.53. We use many routines, including Phoenix, Spirit, bind, tie, etc. I am attempting to migrate to Boost 1.57. Got clobbered with about 400 lines of unexpected diagnostic in the compiler. That is the attached file. In the file, the lines showing the files named "cutoffitem.cpp" and "densitydelegate.cpp" are ours, but what is between these two lines is coming from Boost. It appears that it could be a C++11 type of problem, but I'm not sure . I read about that potential problem with the [utility] [result_of] class template in the report designated n3276 and in the 1.57 [utility] documentation. I think the major concern with this issue was going to Boost 1.52. In our code, I tried a quick-fix precompiler #define, but it did not work. Got any ideas? I'm about to go back to version 1.53, at least until I upgrade to Visual Studio 2013. Thank you, /Andrew Nordquist Research Analyst Southwest Research Institute San Antonio, TX, USA

Multiple defined symbols
by Lloyd 09 Apr '15

09 Apr '15

Hi, I have a "dll" project which is dependent on boost libraries like thread and system. When I compile my project I gen error like libboost_thread-vc120-mt-gd-1_57.lib(thread.obj) : error LNK2005: "public: virtual __thiscall boost::detail::thread_data_base::~thread_data_base(void)" (??1thread_data_base@detail@boost@@UAE@XZ) already defined in boost_thread-vc120-mt-gd-1_57.lib(boost_thread-vc120-mt-gd-1_57.dll) What I understood from this error is, my project is trying to link to both dynamic and static boost libraries. I only want to link to the boost thread dll. To my knowledge am not directly using any boost autolink feature. In the visual studio linking option I have mentioned only the "boost_thread-vc120-mt-gd-1_57.lib". Why could it be trying to link to libboost_thread-vc120-mt-gd-1_57.lib? Is there any way to find where this is happening? Thanks, Lloyd

[units] non-rational scaling
by Matthias Wohlgemuth 08 Apr '15

08 Apr '15

Dear all, I have an issue with scaled units. I tried to implement a non-rational scaling of units adapted from scale<> class (all in boost::units namespace): template<class Derived> struct non_rational_scale { static const unsigned long base = 10; typedef boost::units::static_rational<0> exponent; typedef double value_type; static double value() { return Derived::value(); } static std::string name() { return Derived::name(); } static std::string symbol() { return Derived::symbol(); } }; struct electron_volt_scale : non_rational_scale<electron_volt_scale> { static double value() { return 1.60218e-19; } /* elementary charge in Coulombs */ static std::string name() { return "electron volt"; } static std::string symbol() { return "eV"; } }; typedef make_scaled_unit<si::energy, electron_volt_scale>::type electron_volt; This works fine in one direction: quantity<si::energy>(1.*electron_volt()); /* gives 1.60218e-19 J. */ However, in the other direction quantity<electron_volt>(1.*si::joule); /* gives 1 eV */ I guess, that I need some specialization for non_rational_scale to workout the correct scaling factor in the reverse direction. Thank you for your help, Matthias
