[GIL] Black filled or not ?
by Eloi Du Bois 14 Jan '10

14 Jan '10

Hi all ! I would like to know, when creating an image like that: rgb32f_image_t img(w, h); is the image filled with 0 by default or should I call fill_pixels ? Thank you ! Eloi.

Thanks a lot for the suggestion: I didn't know that std::cbrt() exists! I alway relied on cplusplus.com as reference; I will have to change that! Of course this is again a lot faster: average time to compute 5000000 roots with pow(): 0.613 s. average time to compute 5000000 roots with cbrt(): 0.464 s. Thanks again - I am happy now... ;-) Tim

[regex] Generate matching string
by Roland Bock 14 Jan '10

14 Jan '10

Hi, given a regex, is there a way to create sample strings which would match? Of course, for many patterns, the number of possible strings would be practically infinite. But sometimes it would be helpful to have even one sample of a matching string. Any ideas? Thanks and regards, Roland

asio: selective cancellation of reads/writes
by Alexander Fritze 14 Jan '10

14 Jan '10

Hi, In asio, if I have a socket with pending asynchronous reads and writes, is there a way to selectively cancel only the reads or only the writes? All I can find is basic_stream_socket::cancel() which closes *all* pending operations on the socket. Thanks for any help, Alex

trouble with spirit (boost 1.39)
by Noah Roberts 13 Jan '10

13 Jan '10

void read_formula_line(esi::string_t const& line, table_fluid_data & data) { namespace sp = boost::spirit::classic; using namespace sp; unsigned int index = 0; parse_info<wchar_t const*> info = sp::parse(line.c_str(), // begin grammar ( L'P' >> uint_p[assign_a(index)] //>> uint_p[assign_a(data.formulas[index-1].formula_id)] >> uint_p[boost::bind(&assign_i, _1, boost::ref(data.formulas [index-1].formula_id))] >> real_p[boost::bind(&assign_dbl, _1, boost::ref(data.formulas [index-1].coefficients[0]))] //>> real_p[assign_a(data.formulas[index-1].coefficients[0])] >> real_p[assign_a(data.formulas[index-1].coefficients[1])] >> real_p[assign_a(data.formulas[index-1].coefficients[2])] >> real_p[assign_a(data.formulas[index-1].coefficients[3])] >> real_p[assign_a(data.formulas[index-1].coefficients[4])] >> lexeme_d[*space_p] // necessary to clip off the last bit. ) , space_p); if (!info.full) throw std::runtime_error("Parse fail in formula line."); } The line is being parsed by the above code but the values are not being assigned by the assign_a nor by the boost::bind call to my own val = x setters. The setters are being called correctly, but the data is not getting through for some reason. It's like the data structure is being copied instead of referenced but I'm explicitely using references. Any idea what gives?

Building 1.41 for win64 with python
by Tom Kent 13 Jan '10

I googled around for this, but didn't find any answers. I'm building 64 bit libraries for visual studio on a 32 bit win XP box and getting the attached linker errors. I get similar results with visual studio 8 and 9. Any thoughts?

Boost-users] [asio]about reactor_op_queue dead loop
by victor 13 Jan '10

13 Jan '10

I call boost::asio::async_write, finally it call "bool enqueue_operation(Descriptor descriptor, Operation operation)" In this function , there is code as flow: while (current_op->next_) current_op = current_op->next_; My process execute it for ever. Using gdb to attach the prcocess, I find : 68 while (current_op->next_) (gdb) p current_op $8 = (class boost::asio::detail::reactor_op_queue<int>::op_base *) 0x93381c8 (gdb) p current_op->next_ $9 = (class boost::asio::detail::reactor_op_queue<int>::op_base *) 0x93381c8 current_op and current_op->next_ is the same address. how did it come true? I have no any clue. Anyone can offer some suggestion?

Newbie question: Serialization of an Array2D --> Cell** m_cells
by Simon Ruffieux 13 Jan '10

Hello ! I am trying to serialize a a complex structure. One of the "variable" is a 2D Array (Cell** m_cells ) declared with pointers. I need to keep this data structure as it is.

Note2: As you may understand while reading the code, I have in fact an Array2D of PointAccumulator ....

newbie question --> invalid application of ?sizeof? to incomplete type ?boost::STATIC_ASSERTION_FAILURE<false>?
by Simon Ruffieux 13 Jan '10

Hello ! I am a newbie to Boost ... and trying to use it in order to serialize a complex data structure for one of my project. (the struct particle) You can see the nested data structure at the end of this file. I have started from the 'leafs' and yet trying to serialize a point which is a variable of a PointAccumulator. You can see the point.h file below. Here is the test code I am using to try to serialize it. Note that I read a few succinct tutorials and already succesfully compiled some simple examples. ... GMapping::point<int>p = GMapping::point<int>(); //saveIntoFile<text_oarchive>(particlesSaved[1].map.cell(1,1).acc, "outTest.txt"); saveIntoFile<text_oarchive>(p, "outTest.txt"); ... template <class T> void RobotController::saveIntoFile(GMapping::point<int>& p, const char* file){ std::ofstream ofile(file); T ar(ofile); ar << p; ofile.close(); } However when compiling; it raises the following error: ... /usr/include/boost/archive/detail/oserializer.hpp: In function ‘void boost::archive::save(Archive&, T&) [with Archive = boost::archive::text_oarchive, T = GMapping::point<int>]’: /usr/include/boost/archive/detail/common_oarchive.hpp:64: instantiated from ‘void boost::archive::detail::common_oarchive<Archive>::save_override(T&, int) [with T = GMapping::point<int>, Archive = boost::archive::text_oarchive]’ /usr/include/boost/archive/basic_text_oarchive.hpp:75: instantiated from ‘void boost::archive::basic_text_oarchive<Archive>::save_override(T&, int) [with T = GMapping::point<int>, Archive = boost::archive::text_oarchive]’ /usr/include/boost/archive/detail/interface_oarchive.hpp:64: instantiated from ‘Archive& boost::archive::detail::interface_oarchive<Archive>::operator<<(T&) [with T = GMapping::point<int>, Archive = boost::archive::text_oarchive]’ RobotController.cpp:186: instantiated from ‘void RobotController::saveIntoFile(GMapping::point<int>, const char*) [with T = boost::archive::text_oarchive]’ RobotController.cpp:223: instantiated from here /usr/include/boost/archive/detail/oserializer.hpp:564: error: invalid application of ‘sizeof’ to incomplete type ‘boost::STATIC_ASSERTION_FAILURE<false>’ /usr/include/boost/archive/detail/common_oarchive.hpp:64: instantiated from ‘void boost::archive::detail::common_oarchive<Archive>::save_override(T&, int) [with T = GMapping::point<int>, Archive = boost::archive::text_oarchive]’ /usr/include/boost/archive/basic_text_oarchive.hpp:75: instantiated from ‘void boost::archive::basic_text_oarchive<Archive>::save_override(T&, int) [with T = GMapping::point<int>, Archive = boost::archive::text_oarchive]’ /usr/include/boost/archive/detail/interface_oarchive.hpp:64: instantiated from ‘Archive& boost::archive::detail::interface_oarchive<Archive>::operator<<(T&) [with T = GMapping::point<int>, Archive = boost::archive::text_oarchive]’ RobotController.cpp:186: instantiated from ‘void RobotController::saveIntoFile(GMapping::point<int>, const char*) [with T = boost::archive::text_oarchive]’ RobotController.cpp:223: instantiated from here /usr/include/boost/archive/detail/oserializer.hpp:564: error: invalid application of ‘sizeof’ to incomplete type ‘boost::STATIC_ASSERTION_FAILURE<false>’ make: *** [RobotController.o] Error 1 Anyone understands what is the error ?

Hi to all, i wrote a class (Influx), where i try to define there a boost::multi_arry occ_sign_change. Once i tried in Influx::Influx to write: occ_sign_change = vec::uint32_1d_t ( boost::extents[ num_elements ] ); i was able to compile, but at run time i got the following error: randum.rc3_64: /usr/include/boost/multi_array/multi_array_ref.hpp:487: boost::multi_array_ref<T, NumDims>& boost::multi_array_ref<T, NumDims>::operator=(const ConstMultiArray&) [with ConstMultiArray = boost::multi_array<unsigned int, 1ul, std::allocator<unsigned int> >, T = unsigned int, long unsigned int NumDims = 1ul]: Assertion `std::equal(other.shape(),other.shape()+this->num_dimensions(), this->shape())' failed. that is why i rewrote the above line as following: vec::uint32_1d_t occ_sign_change ( boost::extents[ num_elements ] ); but now, when i call for the size of occ_sign_change in Influx::Clean, i get that the size is zero. how could i solve this problem? regards #include <boost/random/uniform_01.hpp> #include <boost/random.hpp> #include "randum.rc3.hpp" namespace vec { typedef boost::multi_array< uint32_t , 1> uint32_1d_t; typedef boost::multi_array< uint32_t , 2> uint32_2d_t; typedef boost::multi_array< uint32_t , 3> uint32_3d_t; typedef boost::multi_array< uint32_t , 1> uint32_1d_t; typedef boost::multi_array< uint32_t , 2> uint32_2d_t; typedef boost::multi_array< double , 1> double_1d_t; typedef boost::multi_array< double , 2> double_2d_t; typedef uint32_1d_t::index index_t; } class Influx { public: Influx ( uint32_t num_elements , double p_, double kappa_ , vec::uint32_2d_t *Pointer_ , threshold_t threshold_ , uint32_t num_bits , uint16_t max_runs_ ); void Update (); void Validity ( const uint32_t i ); void Clean( uint32_t run ); boost::dynamic_bitset<> occupied; vec::uint32_1d_t occupied_counter; vec::uint32_1d_t num_neighbours; vec::uint32_1d_t occ_sign_change; private: std::vector< uint32_t > remove_node_v; vec::uint32_2d_t *Pointer; std::vector< uint32_t > num_neighbours_epoch; double p; double kappa; threshold_t threshold; uint16_t max_runs; uint32_t bits_mask; uint32_t complement_num; }; Influx::Influx ( uint32_t num_elements , double p_, double kappa_ , vec::uint32_2d_t *Pointer_ , threshold_t threshold_ , uint32_t num_bits , uint16_t max_runs_ ) { bits_mask = ( 1 << num_bits ) - 1; Pointer = Pointer_; p = p_; kappa = kappa_; threshold = threshold_; max_runs = max_runs_; complement_num = 0; num_neighbours_epoch = std::vector< uint32_t > ( num_elements , 0); occupied = boost::dynamic_bitset<> ( num_elements , 0 ); // all 0's by default vec::uint32_1d_t occupied_counter ( boost::extents[ num_elements ] ); vec::uint32_1d_t occ_sign_change ( boost::extents[ num_elements ] ); vec::uint32_1d_t num_neighbours ( boost::extents[ num_elements ] ); remove_node_v.reserve( num_elements ); std::fill_n( occupied_counter.begin() , occupied_counter.num_elements() , 0 ); std::fill_n( occ_sign_change.begin() , occ_sign_change.num_elements() , 0 ); std::fill_n( num_neighbours.origin() , num_neighbours.num_elements() , 0 ); } void Influx::Clean ( uint32_t run ) { for ( vec::uint32_1d_t::size_type i = 0 ; i < remove_node_v.size() ; i++ ) { occupied[ remove_node_v[i] ] = 0; if ( run >= max_runs ) { std::cout << "size occ_sign_change: " << occ_sign_change.size() << std::endl; occ_sign_change[ remove_node_v[i] ]++; } } remove_node_v.clear(); }

[asio] Why are the strands in the "HTTP Server 3" example necessary?
by Tacheon 12 Jan '10

12 Jan '10

In the HTTP Server 3 (http://tinyurl.com/yh95d2b) example of the asio documentation strands are used to synchronize the invocation of completion handlers? But why are they necessary here? As far as I get it, the handlers are invoked in strict sequential order for each distinct connection (http://tinyurl.com/ybohynd) Each connection has its own set of resources so synchronization shouldn't be necessary, should it? Thanks in advance, Boris

gil and OpenGL
by mailinglist＠squarepx.com 12 Jan '10

12 Jan '10

This is my first post in any mailinglist ever so i hope i am doing this right. I successfully integrated the boost::gil module into my code to load some images and process their content so that I can display it as a texture in OpenGL. My problem right now is the massive performance issue in retrieving the color information from the loaded image. I am looping through every row and column and retrieve the red, green, blue and alpha color with the get_color method and push those values to a char array. So I was wondering what the best approach would be to get the color information from the gil image into OpenGL or at least a char array. Thanks in advance.

Hi, Using Visual Studio, it is possible to 'Ignore Specific Library' (Project Properties>Configuration Properties>Linker>Input>Ignore Specific Library). We have found this a useful feature in a project. Now we want to build the project using bjam, but we need to reproduce that linker behaviour. Is there any ignore <library> feature?

Hi, all I am doing one video processing software, which uses Boost::pool as the buffer manager. but every time pool allocates buffers, it malloc all needed memory at one time. for example, I create one pool object for 1024 B for one chunk, and 16 chunks at first. Pool malloc all the 1024 * 16 (16KB) at one time. this leads to memory allocation error for my application, because I need 8294400B (1920 * 1080 * 4, for one video frame) * 32, that is more than 256 MB. I use default new/delete, so new returns NULL for the third time in my case. but from memory monitor, there are still enough memory free. after tracing into new, I found this is from the Microsoft memory management design and memory fragments. is there any way to set Pool to allocate one chunk by another? for example, when I want one chunk, it allocates 8294400B. and for another time, it does another. so this should solve my issues for the memory usage. after checking the code of Pool, it is all based on contiguous memory. if pool cannot meet my requirement, is there any other option in BOOST? BTW, I am working on Windows 32 bits with MS Visual Studio 2005. Thank you for any comment.

utf8_codecvt_facet
by Patrick Horgan 11 Jan '10

11 Jan '10

utf8_codecvt is in libserialization and in libprogram_options--I thought it was moving to utility? Is there one supported spot? Is there any documentation that talks about what to include and link? The .hpp file is still in boost/detail, boost/archive/detail, boost/program_options,boost_filesystem/src, and libs/iostreams/test/detail. Guess it's not cleaned up yet? Or maybe people didn't want cross dependencies? Anyway I need to either use it or write one;) I'm not doing serialization or program_options (yet, who knows, just starting the project). I also need to be able to be able to deal with UTF-16, I don't suppose there's a codecvt facet for that, huh? Patrick

Using 'address-model-32_64' on Mac OS 10.6
by Dane Springmeyer 11 Jan '10

11 Jan '10

I've recently upgraded to a Mac with 64bit firmware and Snow Leopard. I've noticed all applications compiled with g++ now default to 64 bit libs (x86_64), including boost. Thanks by the way for the fixes to boost 1.41 that allow successful 3- way arch compilation on osx again! Now I'm trying to just build two- way arches. I'm now trying to compile boost (I happen to be using trunk), and am noticing that passing 'address-model-32_64' does not seem to have the effect I'd expect. If the flag is passed the only affect I notice is that the build directories include it 'address-model-32_64' in the path, but notably the '-arch -i386 -arch x86_64' flags are not properly added to the CXXFLAGS and LINKFLAGS. Therefore the compiled dynamic libraries are still single architecture, x86_64. Passing 'architecture=combined' does prompt these flags, but includes the 'arch ppc' flag as well which I don't want. So, is it a bug that using address-model alone does not work or am I am misunderstanding something? Thanks for any clarification. Cheers, Dane

Problem iterating over vertices (Property Map!?)
by Pedram Pedarsani 11 Jan '10

11 Jan '10

I am kind of new to C++ and also BGL, so it'll be great if you can help me with this problem! I'm iterating over all the vertices of my graph, and each time I iterate, I want to *mark* a vertex (which has some specific degree for example, or some other property that I can calculate), so as not to iterate over it the next time. I'll do this process until all vertices are marked, so no more iteration. For now, what I'm doing is putting the marked vertices in a separate list, and each time I iterate over all vertices again and I check whether each vertex is in the marked list (which is very inefficient). Could you please help me with an efficient way of doing this? I was thinking to use Property Map but I have no idea how! Any small piece of code will be appreciated. Thanks a lot!

BGL: shared_ptr as bundled properties > how to generate properties maps ???
by Damien Maupu 11 Jan '10

11 Jan '10

Dear all, I am using bundled properties when I define my graph. The bundled properties are smart pointers to my own class Edge and Vertex. I write something like: typedef boost::shared_ptr<Vertex> VertexPtr; typedef boost::shared_ptr<Edge> EdgePtr; typedef adjacency_list<vecS, vecS, directedS, VertexPtr, EdgePtr> Graph; Vertex and Edge being my own classes to store information on the vertices and the edges. For what I read in the doc, this is the correct, more modern way to do it. My problem is the following. I am trying to use the BGL algorithms and some of them require vertex/edge info to be provide as properties maps. From http://www.boost.org/doc/libs/1_41_0/libs/graph/doc/bundles.html I know it is possible to generate those maps from bundled properties. It works well if I don't use shared_ptr but cannot compile otherwise. When using shared_ptr, similarly to the doc, I wrote: typedef property_map<SearchGraph, float EdgePtr::*>::type WeightMap; WeightMap weightMap = get(&EdgePtr::m_cost, *_graph); m_cost being a public float member of my own class Edge. I have the following compilation error: 'm_cost' : is not a member of 'boost::shared_ptr<T>' Indeed it is not. My question is, I can let the shared_ptr access the member? In other world how to deal with bundled properties / properties maps and shared_ptr. Extra question, could 'm_cost' be a private member of my own class Edge? Thank you very much Sincerely, Damien

can serialize multi-class into a single Archive?
by pengdw 11 Jan '10

11 Jan '10

I want to serialize multiple class into a single file. that's: class object {}; ofstream ofs; ofs.open("data.txt"); boost::archive::text_oarchive oa(ofs); while (get_next_object(object_t obj)) { oa << obj; } It is ok when I use text_iarchive to read back these objects. Now I want to append some objects to a Archive, I need to reopen the data file "data.txt" with (ios_base::app | ios_base::out), and serialize some object to the new-opend Archive. then when I use text_iarchive to load, I got error messages. I checked some manuals, and use boost::archive::no_header to skip the archive headers like "22 serialization::archive" when appending objects. but still I got error messages when loading. can anyone tell me how to store and append objects to a single Archive, and load correctly. tks.
