Re: [Boost-users] serialize - C structure within a class
by sui tam 02 Dec '05

I have a class that is using a C struct, when I use the serialization code: typdef struct A { template <class Archive> void serialize( Archive & ar, ) { ar & a1; ar & a2; } type1 a1; type2 a2; } I get error A.h(59): error: this declaration may not have extern "C" linkage template<class Archive> How can I archive this C structure which the class referenced? --------------------------------- Yahoo!

[Test] BOOST_CHECK() -> unknown location(0) when an exception is thrown...
by Kevin Wheatley 01 Dec '05

01 Dec '05

Hi, I have a test where BOOST_CHECK() results in a call that causes an exception, but it gives no location, would it be possible to change the reporting code that catches the exception to report the file and line number to give me 1 click navigation to the site of the calling test? Perhaps the macro could force a check point or something and then log_exception could use that? I'm using BOOST_AUTO_TEST_MAIN as the driver for the tests with BOOST_AUTO_TEST_CASE "functions" Thanks Kevin -- | Kevin Wheatley, Cinesite (Europe) Ltd | Nobody thinks this | | Senior Technology | My employer for certain | | And Network Systems Architect | Not even myself |

[Serialization] Use of BOOST_SERIALIZATION_NVP needs clarification
by Peter Whaite 01 Dec '05

01 Dec '05

I just started using the serialization library and it is very useful. However the minimal documentation for xml archives in the "List of Examples" could be clearer. Right now it says... demo_xml.cpp This is a variation the original demo which supports xml archives in addition to the others. The extra wrapping macros are needed to associate a data item name with the correspoding xml tag. For more information see Name-Value Pairs. Here is what an xml archive looks like. It would help if the "extra wrapping macros" are named. Yes you can figure it out from demo_xml.cpp (well there's only BOOST_SERIALIZATION_NVP in there) and from the "Name-Value Pairs" page, but that is too much jumping around for a first read. But what would help more is a warning that BOOST_SERIALIZATION_NVP must wrap a valid xml tag. For example I naively thought: void editor::save() { ... ar << BOOST_SERIALIZATION_NVP(*this); } would work, but of course it doesnt because "*this" is not a valid xml tag. I searched the list archives, and I'm not the only one who fell into this trap. I suggest adding something like this ... The extra wrapping macro, BOOST_SERIALIZATION_NVP(name), is needed to associate a data item name with the corresponding xml tag. It is importanted that 'name' be a valid xml tag, else it will be impossible to restore the archive. For more information... The warning should be repeated in wrappers.html#nvp, and in the comments in demo_xml.cpp. --- Peter Whaite

Looking for is_base_of
by Dave 01 Dec '05

01 Dec '05

Hello all, For the life of me, I cannot find is_base_of<>. What header files / namespaces do I need to reference to get at this little guy? Actually, I'm starting to think it has been replaced and that I should be looking for something else... Thanks, Dave

[Boost.Format] empty string argument causes VC 8.0 to assert
by Mick Hollins 01 Dec '05

01 Dec '05

The following code causes a runtime assertion in VC 8.0: std::string l_param; std::string l_str = (boost::format("here is an empty string: %1%") % l_param).str(); It passes an empty string argument to boost::format. The assert is inside the implementation of basic_string::append() and boils down to the fact that the implementation of boost::format ends up calling basic_string::append(const char *, size_type) with a null pointer, which causes basic_string::append to assert. The following sample code causes the same assertion without boost::format being involved: std::string l_str; const char *l_null = NULL; std::string::size_type l_size = 0; l_str.append(l_null, l_size); // causes an assert I have currently disabled the assertion by calling the following code before I do anything else: #if _MSC_VER >= 1400 _CrtSetReportMode( _CRT_ASSERT, _CRTDBG_MODE_FILE); _CrtSetReportFile( _CRT_ASSERT, _CRTDBG_FILE_STDERR ); #endif which causes the asserts to simply emit a message to stderr rather than to pop up a message box, but I don't really want to disable VC 8.0's assertions across the board. My questions are: 1) Is this considered to be a bug in boost::format or a case of VC 8.0's runtime checks being overzealous? Personally I feel that calling append(null, 0) should be allowed and VC 8.0 is being too protective, but the copy of the C++ standard I have suggests that VC 8.0 is correct. 2) Either way, what do people think is the best way forward? thanks, mick

The problem about shorthest path computation
by liu jianfei 01 Dec '05

01 Dec '05

Hi, all Recently, I faced a big problem when I'm using the boost function of shorthest path computing including dijkstra_shortest_paths and johnson_all_pairs_shortest_paths. My projectet was that I extracted all the surface voxels of a volume as the vertexs of the graph, and 26-connection between them as a edge. Hence, I got a large sparse graph which composed of 12768 vertexs and around 86000 edges. In the next stage, I implemented the dijkstra_shortest_paths computation for each vertex. However, it succeded in some points and failed in other points. If I changed the weight of each edge into 1, all points worked. If I used other weights for different edges, then problem poped up. Also, some points worked for this special weight, and failed for others. I think the shortest path algorithm should be unrelated with the weight assignment. Initially, I think something was wrong in my graph buliding. But when I wrote the shorthest path algorithm by myself and all points worked, I felt there may be a bug in dijkstra_shortest_paths class. If someone else faces the same problem, feel free to tell me. If not, I'm willing to paste my graph code in spite of its complexity. Thanks Regards!

Compilation difference between intel 9.0 and msvc 7.1 regarding const
by Chris Goller 30 Nov '05

30 Nov '05

I have code that will compile using msvc 7.1 but will not under intel 9.0. Here is some simplified code to illustrate my problem: using namespace boost; using namespace std; typedef array<int, 2> array_type; array_type a; a[0] = 0; a[1] = 1; vector<array_type> v; v.push_back(a); vector<int> h; for_each(v.begin(), v.end(), mem_fun_ref(&array_type::front)); This compiles and runs using msvc 7.1, but intel 9.0 errors with the following: error: more than one instance of overloaded function "mem_fun_ref" matches the argument list: function template "std::mem_fun_ref(_Result (_Ty::*)() const)" function template "std::mem_fun_ref(_Result (_Ty::*)())" argument types are: (<unknown-type>) Here are the two definitions of front for boost::array: reference front() { return elems[0]; } const_reference front() const { return elems[0]; } If I'm reading the error correctly, this means that the intel compiler doesn't know if I want to use the const or non-const version of front. Does anyone know anything about this? Is this the forwarding problem? Is a function wrapper around front a good solution? What are the solutions? Thanks, Chris

[Boost.Iostream] missing BOOST_IOSTREAMS_DECL in mapped_file.hpp
by Marc Viala 30 Nov '05

30 Nov '05

Hi, I'm not really sure but I think there are some missing export declarations in the "mapped_file.hpp" of Boost.Iostream. The missing declarations are for the struct mapped_file_sink and the class mapped_file. I've joined the corrected "mapped_file.hpp" Could you confirm these observations? Marc Viala

Re: [Boost-users] Overload problem with bind
by Kerner, Jacques 30 Nov '05

Okay, just to nail it down : - boost::bind does not generate the error and you don't need to cast the function pointer whereas - boost::lambda::bind needs you to explicitely cast the function pointer Thank you!

Yes. This works: boost::lambda::bind( static_cast<float& (Position::*)() > (&Position::GetX), boost::ref(myPos)); Also, boost::bind doesn't seem to have this problem.

[Boost.date_time] Missing export declaration in parser.hpp
by Marc Viala 30 Nov '05

30 Nov '05

Hi, I'm not really sure but I think there are some missing export declaration in the "parser.hpp" of Boost.date_time. The missing declarations is for function "special_value_from_string()" I've joined the corrected "parser.hpp" Could you confirm these observations?
