using uint8_t & the like on open solaris
by Maróy Ákos 27 Nov '09

27 Nov '09

Hi, I'm have a silly problem of trying to use the integer type definitions in boost/cstdint.hpp in the following way: #include <boost/cstdint.hpp> using namespace boost; uint8_t value; on other platforms I've tried, this seems to be OK, but on OpenSolaris, with gcc 3 I get an error that uint8_t does not name a type, with gcc 4, it will say that uint8_t is ambiguous, since there's a typedef also in /usr/include/sys/int_types.h of course the above works the following way: boost::uint8_t value; but I really wanted to avoid having to specify the boost namespace all the time.

BGL: counting connected components subgraph
by Arman Khalatyan 27 Nov '09

27 Nov '09

Hello, I wondered are there way to count connected components in the minimum spanning tree? Currently I just making copy of graph to be able to count and collect connected components are there more efficient way to do that? ______________________________ std::vector < Edge > spanning_tree; Graph graphMST; kruskal_minimum_spanning_tree(graphFOREST, std::back_inserter(spanning_tree)); for (std::vector < Edge >::iterator ei = spanning_tree.begin(); ei != spanning_tree.end(); ++ei) { if(get(edge_weight, graphFOREST, *ei)<1.0)//lets cut the MTS by given threshold add_edge(source(*ei, graphFOREST),target(*ei, graphFOREST),get(edge_weight, graphFOREST, *ei),graphMST); } num = connected_components(graphMST, &component[0]); // Use components... _______________________________ Thank you beforehand Arman.

Automating Serialization?
by Bilokon, Paul 26 Nov '09

26 Nov '09

Hi, By design Boost Serialization requires the user to list each field that needs to be serialised. This is in contrast, for example, with Java and some other languages where serialisation is supported (kind of) at the language level. The current approach requires some code duplication. We have to declare a field. We have to manually (de)serialise it. If we need to make a change, we make it in at least two distinct places. Is there any way to automate the process of serialisation, perhaps harnessing the power of the preprocessor? E.g. we could label the fields that need to be serialised. Is there anything in Boost that could help? Many thanks, Paul Paul Bilokon, Vice President Citigroup | FX - Options Trading | Quants 33 Canada Square | Canary Wharf | Floor 3 London, E14 5LB Phone: +44 20 798-62191 paul.bilokon(a)citi.com<mailto:paul.bilokon@citi.com>

[shared_ptr] hangs on iPhone
by Igor R 26 Nov '09

26 Nov '09

Hello, My application works on iphone simulator, but hangs when running on iphone itself. Pausing it and looking at the stack trace shows the picture very similar to the one desribed here: http://article.gmane.org/gmane.comp.lib.boost.user/47644 I.e., the call stack origins from different place each time, but ends up with an attempt to addref shared_ptr and spinning in the spinlock. I could try and use XCode "native" tr1::shared_ptr version, but boost::shared_ptr is used by many other boost libraries, so it wouldn't help. So my question is if there's any fix/workaround/compiler-switch that I can apply to overcome this issue and avoid re-writing the whole project without boost? Thanks!

Query regarding compiling BOOST parallel graph library
by praga 26 Nov '09

26 Nov '09

Hi All, I am using BOOST 1_41_0 version. I compiled it using bjam --with-mpi install --prefix=somepath in the BOOST home directory. I am not sure whether this is enough to get the parallel graph library also compiled. How can I verfity whether my parallel graph library also compiled ? If it is compiled how to run the test programs given the test directory ? Can anybody give me some directions on this ? Thanks, Praga.

[GIL] How to read fixed point channel ?
by Eloi Du Bois 26 Nov '09

26 Nov '09

Hi, I have a stream with 8.8 (16b) channels encoded with fixed point arithmetics (http://knol.google.com/k/anonymous/fixed-point-arithmetic/1b19ktdbl6g9q/2#) and I need to create a rgb16 view that can hold my image... I tried with interleaved_view but this makes wrong values. I don't know how to manage with this... How must be encoded the shorts in a rgb16_image_t ? If anyone could help me, that would be great. Thanks, Eloi.

E.g. we could >label the fields that need to be serialised. Is there anything in Boost that could help? The C++ Middleware Writer doesn't have that problem -- http://webEbenezer.net/comparison.html . (There's a performance section on that page using Boost 1.38. We're in the process of updating that page using Boost 1.41 and hope to have those results on line in the next two weeks.)

Are there any users who are using the LEDA interfaces to Boost.Graph? There are several tickets filed against them but the tickets are all years old. Is it safe to remove them? Do they need a deprecation period first? -- Jeremiah Willcock

boost::serialization, archive not deserializing correctly
by David Claridge 26 Nov '09

26 Nov '09

Hi, I'm trying to use the boost::serialization text_iarchive/text_oarchive, in a way very similar to the tutorial (http://www.boost.org/doc/libs/1_35_0/libs/serialization/doc/tutorial.html) I have confirmed that the data that gets serialized is identical to what is read in when I deserialize (in the code below inbound_data_ is identical to the contents of the text_oarchive stream), however the serialize function does not seem to work correctly. The code to deserialize looks like: std::string archive_data(&inbound_data_[0], inbound_data_.size()); std::istringstream archive_stream(archive_data); boost::archive::text_iarchive archive(archive_stream); archive >> t; where the corresponding serialize() function is: template<class Archive> void Blackboard::serialize(Archive & ar, const unsigned int version) { ar & gameController.our_team; } (gameController.our_team is a member of the 'Blackboard' class) when serializing, our_team is equal to 1, when deserializing, it gets set to zero. Any thoughts on what I might be doing wrong? I can post more details of the code if that would be helpful. Thanks! -- Dave

Re: [Boost-users] covariance calculus via boost::accumulators
by Conoscenza Silente 25 Nov '09

25 Nov '09

Hi All I would like to calculate the covariance of 2 variables. I found that in Boost there is boost::accumulators and the Statistical Accumulators Library that looks good to me. Covariance is a measure of how much two variables change together, but in the example given by boost ( I am guessing) I see only an example for one variable. I did not really understand how to setup the accumulators for 2 or more variables. What role plays the covariate here and where to pick up or feed the values for the second variable? Thanks to all accumulator_set<double, stats<tag::covariance<double, tag::covariate1> > > acc; acc(1., covariate1 = 2.); acc(1., covariate1 = 4.); acc(2., covariate1 = 3.); acc(6., covariate1 = 1.);

In doing this I have noted. o creating small trivial cases seemed to work. o when I combined the test case files to a single file, it worked In trying to create the test case I figured out what caused the crash, Basically I had included text archive in all the compilation units but the binary archive _only_ in the file where I was outputting to the disk. When I included the binary archive in _all_ the compilation units that were being serialized, the test worked. I am not sure how common this case is, but gcc compiler/linker gave no warnings Maybe this need to be added as a gotcha in the documentation? Best regards, Ta, Avi

[Serialization] Serialize shared_ptr compile error
by elizabeta petreska 25 Nov '09

25 Nov '09

Hello I can't compile my simple project for serializing shared_ptr . I read the archives and google it and still can't compile it :) I am doing the following : /////A.h #pragma once #include <boost/archive/xml_iarchive.hpp> #include <boost/archive/xml_oarchive.hpp> #include <boost/serialization/nvp.hpp> #include <boost/serialization/shared_ptr.hpp> class A { public: A(int k):mk(k) { } A() { } template<class Archive> void save(Archive & ar, const unsigned int version) const { using boost::serialization::make_nvp; ar & BOOST_SERIALIZATION_NVP(mk); } template<class Archive> void load(Archive & ar, const unsigned int version) { using boost::serialization::make_nvp; ar & BOOST_SERIALIZATION_NVP(mk); } BOOST_SERIALIZATION_SPLIT_MEMBER() int mk; }; BOOST_SERIALIZATION_SHARED_PTR(A) ///func.cpp #include "A.h" void func() { std::ofstream ofs(L"C:\\boostarchiveSharedPtr.xml"); std::ifstream ifs(L"C:\\boostarchiveSharedPtr.xml"); boost::shared_ptr<A> bPtr(new A(13)); { using boost::serialization::make_nvp; boost::archive::xml_oarchive oa(ofs); oa & BOOST_SERIALIZATION_NVP(bPtr); } boost::shared_ptr<A> rbPtr; { using boost::serialization::make_nvp; boost::archive::xml_iarchive ia(ifs); ia & BOOST_SERIALIZATION_NVP(rbPtr); } } And I am getting the following compile time error : 'boost::mpl::assertion_failed' : cannot convert parameter 1 from 'boost::mpl::failed ************boost::serialization::is_wrapper<T>::* ***********' to 'boost::mpl::assert<false>::type' D:\main\dev\sdk\libs\boost\inc\boost-1_38\boost\archive\basic_xml_oarchive.hpp 88 The comment about the erroir says : // If your program fails to compile here, its most likely due to // not specifying an nvp wrapper around the variable to // be serialized. I can't understand what does it mean, since I have BOOST_SERIALIZATION_NVP when writing /reading to the archive

Ok I have managed to reproduce the crash in binary archive in a set of standalone files, i.e 8 files. But last time I included a tar, it got stripped. Would it be ok to just embed the file in the email or is there some other mechanism to attach file/tar files ? Best regards, Ta, Avi

handling unicode strings / encodings?
by Maróy Ákos 25 Nov '09

25 Nov '09

Hi, I wonder what the state of handling unicode strings is in C++ / with boost? I've found some references to the codecvt<> feature, and also I've found utf8_codecvt_facet among the boost sources, but I can't really make it work. what I would need is to handle strings based on the whole unicode representation, and to encode them to UTF-8 and back. is there anything related in boost?

[GIL] Help on rgba 10 bits views
by Eloi Du Bois 25 Nov '09

25 Nov '09

Hi, I would like to know how can I create a 10 bits view that makes it possible to use interleaved_view. My data are described as follow: R10G10B10A10;R10G10B10A10;R10G10B10A10;R10G10B10A10;..... You understand easily that a rgba pixel is stored on 40 bits... I tried this: typedef bit_aligned_pixel_reference<uint64_t, > mpl::vector4_c<uint16_t, 10, 10, 10, 10>, rgba_layout_t, true> > rgba10101010_ref_t; > // A mutable iterator over RGB101010 pixels > typedef bit_aligned_pixel_iterator<rgba10101010_ref_t> > rgba10101010_ptr_t; > typedef std::iterator_traits<rgba10101010_ptr_t>::value_type > rgba10101010_pixel_t; > // View type from pixel type > typedef view_type_from_pixel<rgba10101010_pixel_t>::type > rgba10101010_view_t; > rgba10101010_view_t src; > But it does a mess with my pixels... (and makes it impossible to use copy_and_convert_pixels(src, rgba16_view_t(view(img))); ) If anyone could help me, that would be great ! Thank you by advance, Eloi.

binary serialization, what's missing
by Avi Bahra 25 Nov '09

25 Nov '09

I have a complex tree structure. When this is serialized with text archive all is well. (i.e on linux/gcc) However when I attempt to use the binary archive, it crashes when trying to serialize a base pointer ? I though that text and binary were interchangeable, have I missed something or is serialization via base pointer not implemented in binary ? Any help appreciated. Best regards, Ta, Avi

Jeff Wrote: >Are the underlying streams opened as binary? > >Jeff Yes, This is how I save, the the restore is analogous. Using boost 1.39 void save(bool binary) const { if (binary) { std::ofstream ofs( fileName_.c_str(), ios::binary ); boost::archive::binary_oarchive oa( ofs ); oa << *this; } else { std::ofstream ofs( fileName_.c_str() ); boost::archive::text_oarchive oa( ofs ); oa << *this; } } Ok I was trying eventually to use the portable binary archive, however I suspect that would crash as well. I will try to create a standalone program that shows the crash using the binary archive first. Best regards, Ta, Avi

issues with setting properties on reverse graph
by Mangal 24 Nov '09

Trying to set graph properties on reverse graph does not seem to be working. I am using boost 1.40.0 A simple program where we set graph_name to "graph" on a reverse graph does not work int main() { using namespace boost; using std::string; typedef adjacency_list<vecS, vecS, directedS,no_property, property<edge_index_t, int>, property<graph_name_t, string> > graph_t; typedef reverse_graph<graph_t> reverse_graph_t; graph_t g; reverse_graph_t sg = reverse_graph_t(g); std::string Name = "graph"; set_property(sg, graph_name, Name) ; std::cout << "name: " << get_property(sg, graph_name) << std::endl; return 1; } Name comes out to be empty in this case. any ideas??? -- View this message in context: http://old.nabble.com/issues-with-setting-properties-on-reverse-graph-tp263… Sent from the Boost - Users mailing list archive at Nabble.com.
