I seem to recall that there was another news group dedicated to 'spirit' questions - but i couldn't find any links from the spirit homepage (after a cursory look) Could anyone direct me towards the appropriate forum for user-level questions. thanks, -fas

Incompatibilities between Date_Time/PosixTime and Boost.Python !?!?!?
by acid_til <bluc＠videotron.ca> 04 Feb '03

04 Feb '03

Hi !! When trying to compile a simple program (just a main and nothing in it) I get a lot of compile error... I'm using VC 6.0 SP5, STLport 4.5.3 and boost 1.29. This is what I include in the program : #include <iostream> #include <boost/python.hpp> #include <boost/date_time/posix_time/posix_time.hpp> Here are the error messages : boost\date_time\compiler_config.hpp(33) : error C2782: ' __cdecl _STL::abs()' : template parameter 'T' is ambiguous could be 'long double' or 'const struct _STL::complex<long double> &' boost\date_time\compiler_config.hpp(33) : error C2785: ' __cdecl _STL::abs()' and 'long double __cdecl _STL::abs(const struct _STL::complex<long double> &)' have different return types \boost\date_time\compiler_config.hpp(30) : see declaration of 'abs' boost\date_time\compiler_config.hpp(33) : error C2782: ' __cdecl _STL::abs()' : template parameter 'T' is ambiguous could be 'double' or 'const struct _STL::complex<double> &' boost\date_time\compiler_config.hpp(33) : error C2785: ' __cdecl _STL::abs()' and 'double __cdecl _STL::abs(const struct _STL::complex<double> &)' have different return types boost\date_time\compiler_config.hpp(30) : see declaration of 'abs' boost\date_time\compiler_config.hpp(33) : error C2782: ' __cdecl _STL::abs()' : template parameter 'T' is ambiguous could be 'float' or 'const struct _STL::complex<float> &' boost\date_time\compiler_config.hpp(33) : error C2785: ' __cdecl _STL::abs()' and 'float __cdecl _STL::abs(const struct _STL::complex<float> &)' have different return types boost\date_time\compiler_config.hpp(30) : see declaration of 'abs' Has this been reported ??? Are Boost.Python and posix_time incompatible ??? If not, can someone point to a solution. Thanks a lot for your time. Luc.

RE: [Boost-Users] HP, aCC and the standards

I would recommend contacting the aCC support people. They are generally quite reasonable. In fact, the hp status tables (which appear a bit out of date) at http://www.boost.org/status/cs-hpux.html are run remotely on a box provided by HP for boost to use. At the point when this was set up, I was investigating whether we should use aCC or g++. I went through and developed a few simple test cases to demonstrate the bugs in a few of the tests. They accepted them, but gave no time line. I think development of aCC was initially really hurt when Daveed Vandevoorde went to EDG, and I'd guess all the linux/compaq hubbub probably hasn't helped to much. I think A.03.33 was released over a year ago. > -----Original Message----- > From: dlux42 <dlux(a)spam.sch.bme.hu> [mailto:dlux@spam.sch.bme.hu] > Sent: Monday, February 03, 2003 7:53 AM > To: Boost-Users(a)yahoogroups.com > Subject: [Boost-Users] HP, aCC and the standards > > > Hello Guys! > > I am now fighting with HP to recognize that their compiler is buggy.

Member Function Iterator Adaptor
by Duane Murphy 04 Feb '03

04 Feb '03

I'm trying to build a member function iterator adaptor. (Maybe there already is one and I'm not finding it?) This would be an iterator adaptor where the adaptor returns the result of calling a member function of the base iterator. I think this is a pretty straightforward iterator adaptor. What I am missing is the ability to work out the value_type of the iterator. This would be the return type of the member function being used. I thought I could use boost::call_traits< MemberFunction >::value_type, but that returns the entire type of the member function. I think call_traits<> is not what I am looking for. Pointers or suggests would be greatly welcomed. Thanks! ...Duane

using boost graph library in VC++
by charlie_zhang66 <charlie_zhang66＠yahoo.com> 03 Feb '03

03 Feb '03

Hi, I downloaded the boost graph library and extract the zip file to root directory C:\boost_1_29_0 . I tried to use it to develope a project in VC++. I built the example file adj_list_cc.cpp, but the compiler give message "can not open boost/graph/graph_concepts.hpp". Based on the installation on the website, I added 'c:/boost_1_29_0' to the #include<...> line. Then, I builted it again, the compiler said other library could not be opened. I want to know whether I should add 'c:/boost_1_29_0' to all the related #include<...>. Is there an easier way to use the library? Thanks Charlie

[BGL] Using BGL for huge graphs
by Erik Arner 03 Feb '03

03 Feb '03

Hi, has anybody tried using BGL for really huge graphs? I mean graphs that are so big that there's no way to store the whole graph in memory. Any ideas on how it should be implemented? My first thought is that it should be fairly straightforward: simply construct classes that model Sequence or RandomAccessContainer for the VertexList parameter etc. The classes store part of the data in memory and read/write data to disc when necessary. Any pitfalls, gotchas or other stuff I should be aware of before embarking on this? Thanks, /Erik

More on static linkage
by Amittai Aviram <amittai＠amittai.com> 01 Feb '03

01 Feb '03

I have been trying to link the boost::regex library to a DLL (Release build) without success and I really need help. I have learned something new. Hitherto, I have put this line right above my code in one of my header files, i.e., within the "#if !defined()" block that prevents duplicate inclusion: #define BOOST_REGEX_STATIC_LINK This has no effect on the build whatsoever. The resulting DLL is no bigger and the client will not work if you rename boost_regex_vc6_mdi.dll from its place. You get an error message from the client saying that this file is missing. If, however, I place the line above as the very first line in a header file, then, instead, I simply cannot compile and build the project at all. The compile error I am getting states that there are "multiply defined symbols"! I.e., the symbols defined in the library are being defined twice. This is driving me nuts. Thanks for any help.

Static linkage in VC++
by Amittai Aviram <amittai＠amittai.com> 01 Feb '03

01 Feb '03

I am trying to get my DLL to get linked statically with the boost::regex library and having _no success_. I have tried putting this line into one of the header files: #define BOOST_REGEX_STATIC_LINK And I have tried this line, alone and in combination with the above: #define BOOST_REGEX_NO_LIB I have tried putting the .lib file boost_regex_vc6_mdi.lib into the list of includes under Project->Settings->Link, with or without the above lines. I give up! And of course people want this thing yesterday. Please help? Thanks. Amittai Aviram amittai(a)amittai.com

Boost and the Lawyers: A Happy Ending (well for us anyway)
by Brian <bneal＠zeus.ia.net> 31 Jan '03

31 Jan '03

Hello again, A while back I posted a series of questions about what other people had done to make their companies lawyers happy about using boost in a commercial project. If you remember, I stated that our lawyers were worried that someone could post someone else's code to boost, passing it of as his own. Our company would then be liable for copyright infringement and other bad things. We thought at the time that we would have to contact each and every boost developer (whose libraries we use) and get them to sign something to say in effect "Yes I wrote this and you have permission to use it". This raised interesting questions like "should there be a standard boost license to make this process less painful"? Well our contracts guy got back to my team of developers. He checked out www.boost.org and did some research on boost. He came to the conclusion that boost was a widely known and used resource, and I guess "trustworthy". All he told us to do was include the boost developers copyright statements on any GUI and to embed said copyright strings into the executable along with ours. Somehow we lucked out. I hope you all have sensible people working for your company too. Thanks, BN And special thanks to the authors of the crc, shared_ptr, regex, and any libraries. You guys ROCK!
