building boost with unsupported compiler
by McLemon, Sean 23 Jun '09

23 Jun '09

Hi, I'm looking to build Boost with a compiler not currently supported, but I'm struggling to find information on where I should really begin. It seems that I'll need to create my own toolset module (something like ..../boost_1_39_0/tools/build/v2/tools/blackfin.jam) with the toolchain's specific build switches etc, rebuild bjam then build Boost. I presume that boost also has some libraries which may need some specific options, or tweaking to work but am I getting the gist of it correctly? Should I be expecting major configuration headaches (toolchain-specific build\runtime issues aside) in adding a new architecture? Thanks, - Sean

[General] Pointer dereferencing by fn call.
by Robert Jones 23 Jun '09

23 Jun '09

Does this template<class T> T& *deref*( T* p ) { return *p; } exist anywhere in Boost? It's the kinda thing you need quite often when using bind, but I can't find it anywhere, which surprised me! Thanks, - Rob.

[boost][graph] Efficiency problems in boost::adjacency_list
by Yinghai Lu 23 Jun '09

23 Jun '09

hi, erveryone, I'm building a graph incrementally using boost::adjacency_list with bundled properties. I did the following typedef: typedef boost::adjacency_list<setS, vecS, bidirectionalS, EdgeClass, NodeClass> Graph; EdgeClass and NodeClass is some classes holding the properties of edges and nodes so that I can access them by using g[u].some_property = 1; My problem is that I'm building the graph incrementally and the graph is huge. And with the definition I'm using the vector to hold the vertices, which results in many memory relocation and copy and makes the program stagnate. I wanted to use listS/mapS for the vertex list instead. However, the bundled property seems to work only with vecS only. Otherwise, compilation error will be thrown. So does anyone know how to solve this problem? Thanks. -- Best Regards, Yinghai

program_options and value<T>
by Zachary Turner 23 Jun '09

23 Jun '09

I want to extend the program_options to support parsing of value types that are not supported by default. For example, parsing of enum types. Suppose I have an enum typedef enum { ValueA, ValueB, ValueC } TestEnum; as well as some other enums. What I'd like to do is something like this: options_description options; variables_map variables; options.add_options() ("test", value<TestEnum>(), "test") ("test2", value<TestEnum2>(), "test2"); etc. So that on the command line I can specify something along the lines of foo.exe --test=ValueA --test2=ValueAA and it will automatically convert them appropriately. Anyone can point me in the direction?

binary mpl::transform fails to compile with fusion::vector
by Mike Tegtmeyer 22 Jun '09

22 Jun '09

I am hoping someone can point me the in right direction regarding this code snippit failing to compile. My suspicion is that it is a header problem but any help would be appreciated. In short, I seem to be missing why the binary form of mpl::transform won't work with fusion::vector. (unary form works just fine). The code below just attempts to make a std::pair<> from the contents of two sequences (this is just an example to illustrate the transform problem). If the two sequences are mpl::vectors, everything is fine. If they are fusion::vectors then 'lots of errors'. I'm fairly new to both mpl and fusion so I am not ruling out the fact that I have done something stupid. Thanks in advance, Mike See code below. #include <boost/mpl/transform.hpp> #include <boost/mpl/vector.hpp> #include <boost/fusion/include/mpl.hpp> #include <boost/fusion/container/vector.hpp> #include <utility> using namespace boost; struct my_make_pair { template<typename T1, typename T2> struct apply { typedef std::pair<T1,T2> type; }; }; int main(int argc, char *argv[]) { #if 0 typedef mpl::vector<int,long> seq1; typedef mpl::vector<float,double> seq2; typedef mpl::vector<std::pair<int,float>,std::pair<long,double> > pairs; typedef mpl::transform<seq1,seq2,my_make_pair>::type result; BOOST_MPL_ASSERT(( equal<result,pairs> )); #endif typedef fusion::vector<int,long> seq1; typedef fusion::vector<float,double> seq2; typedef fusion::vector<std::pair<int,float>,std::pair<long,double> > pairs; typedef mpl::transform<seq1,seq2,my_make_pair>::type result; BOOST_MPL_ASSERT(( equal<result,pairs> )); return 0; }

Simple fast parsing
by Christopher Jefferson 22 Jun '09

22 Jun '09

I am currently using in a project a custom-writen recursive-decent parser, which uses an filtering_istream so I can support compressed input. The only functionality used is peekchar, getchar and integer extraction with 'stream >> i'. I am finding that C++ streams, particularly when it comes to integer extraction, are giving terrible performance. In a small test, uncompressing to a buffer and then writing a simple custom reader on that memory buffer gives 10x performance. I would perfer not to write and support such a tool if possible. Is there a boost library which easily supports a parser with 1 character lookahead and simple things like integer extraction? Looking at the documentation, Boost::Spirit seems like a very big hammer to crack this quite small nut, and it is unclear to me how well it would fit into an existing recursive decent parser. Has anyone ever used it as such? Is there a simple alternative? Chris

[Asio] Confusion with socket.cancel()
by Laurent Fert 22 Jun '09

22 Jun '09

Hi, I am getting confused, could anyone clarify the following points? (Note that I am in a single thread context) 1- After a call to socket.async_send_to(buffer, remote_endpoint, write_handler) followed by a call to socket.cancel() is it possible that the write operation completed before I called cancel() and that my write_handler will be called with no error? 2- After a call to socket.async_send_to(buffer, remote_endpoint, write_handler) followed by a call to socket.cancel() is it possible that some data has actually been written to the socket (let's assume the buffer is quite big) and that then, the operation has been canceled? In such case, would my write_handler be called with both boost::asio::placeholders::error set AND boost::asio::placeholders::bytes_transferred equal to the partial data that has been written? Thanks, Laurent

Trying to use bundled properties like so. typedef std::string Colour; struct edge_properties { string eName; set< Colour > Colours; }; Then the following works OUTSIDE the vis object. graph_t::edge_descriptor e = *edges(g).first; g[e].Colours.insert("5ty"); g[e].Colours.insert("6"); g[e].Colours.insert("7"); set<Colour> set(g[e].Colours); for(std::set<Colour>::iterator si = set.begin(); si != set.end(); si++) std::cout << *si << " "; But if I try to use edge property.Colours INSIDE the vis object (using maps or not) like so. typedef set< string > Set; for(colour_iter=Colour.begin(); colour_iter != Colour.end(); ++colour_iter) { //Set & set = get(m_eColours_map, e); get(m_eColours_map, e).insert( *colour_iter ); //set.insert( *colour_iter ); //g[e].Colours; //g[e].Colours.insert("Green"); //g[e].Colours.insert(*colour_iter); //g[e].Colours.insert("5"); //g[e].Colours.end(); } It compiles but gives Segmentation fault no matter what I try. Im beginning to think that set< string > will not work inside the vis object. If thats true I'll have to rewrite a major part of my program, but I hope not.

[BGL] IncidenceGraph and out_edges

Hello, I do a repost here because of a silly subject copy and paste error of me, sorry for that! The text of my original message is: I'm trying to implement the IncidenceGraph concept for an non-BGL undirected graph like datastructure. Following the boost documentation the target function used with edges from out_edges(u,g) must give vertices != u. Can somebody please explain me why this requirement is in BGL! I think it can make the adaption very difficult as it requieres to artificially orientate undirected edges for each call to out_edges. Any help would be much appreciated! best regards, Chris

[Q] serializing Database Null values (design question)
by V S P 20 Jun '09

20 Jun '09

I have my CPP ORM pretty much working (so that I can read data from the database and serialize it with boost serialize) in generic manner. There is an issue however with 'Nulls' that possibly exist in the database. I use underneath OTL c++ db library and it has a 'null indicator' like many db libraries do. So if I see a value where null indicator is set to true, should I serialize it out and if yes -- is there something like 'NaN' for all the different value types defined? or should I skip serializing that specific field? that would I think work (unless I do not foresee something) -- in the sense that the field will not get loaded back by 'unserialize' and therefore will contain the value assigned in its constructor. just wanted to hear opinions on this. thank you -- V S P toreason(a)fastmail.fm -- http://www.fastmail.fm - mmm...

[Q] reading back serialized Collection of shared_ptr
by V S P 20 Jun '09

20 Jun '09

I made may be a little more headways since my previous question and now have an xml archive that appears to 'denote' the shared pointers (see below) To do this I found and used boost template function specifically for shared pointers -- a data member of myclass inheritin from std::multiset -- TRow is the Value type of the multiset that implements 'serialize' method -- -- struct { template <typename Archive> void serialize (Archive& ar, const unsigned int version)const { for(tThisClassConstIterator it=this->begin(); it!=this->end(); ++it) { boost::serialization::save<Archive,typename TRow>(ar,*it,version); } } tTEST_TB3 now however I do not understand how to 'deserialize this' The basic call to void load_table (tTEST_TB3& t, const char * filename) { // open the archive std::ifstream ifs(filename); assert(ifs.good()); boost::archive::xml_iarchive ia(ifs); ia >> BOOST_SERIALIZATION_NVP(t); } does not even compile, I suspect it is because when this 'serialize' function on tTEST_TB3 is called, now the boost::serialization::save<Archive,typename TRow>(ar,*it,version); is NOT valid, because the ar is of type iarchive, and save function on the shared_ptr is not defined for 'iarchive', only for oarchive. So there is another function in the same boost header file ( #include <boost/serialization/shared_ptr.hpp> ) that defines a 'load' function for the shared ptr However -- what I do not undestand is how to invoke this function it seems like I have to iterate through every entry in the archive and then call load to read it into a shared ptr? That seems to be contrary to all the other mechanism supported by the Serialization library. The basic examples just say that I can take a container and just shift it in (or out) of Archiver -- but that does not work if the container is of shared pointers. That's why I went the route of iterating through every element of the container to serialize, and not do not undestand how to load it back. So I need some help (I can provide the complete example if needed) thank you in advance ---------- <?xml version="1.0" encoding="UTF-8" standalone="yes" ?> <!DOCTYPE boost_serialization> <boost_serialization signature="serialization::archive" version="5"> <t class_id="0" tracking_level="0" version="0"> <px class_id="1" tracking_level="1" version="0" object_id="_0"> <otrq_prov_id>1245439719</otrq_prov_id> <clnt_dbid>1245439719</clnt_dbid> <mydate>6/19/2009 15:28:39</mydate> <amount>33222112121.212000</amount> </px> <px class_id_reference="1" object_id="_1"> <otrq_prov_id>1245439719</otrq_prov_id> <clnt_dbid>1245439719</clnt_dbid> <mydate>6/19/2009 15:28:39</mydate> <amount>33222112121.212000</amount> </px> <px class_id_reference="1" object_id="_2"> <otrq_prov_id>1245439719</otrq_prov_id> <clnt_dbid>1245439719</clnt_dbid> <mydate>6/19/2009 15:28:39</mydate> <amount>33222112121.212000</amount> </px> <px class_id_reference="1" object_id="_3"> <otrq_prov_id>1245439719</otrq_prov_id> <clnt_dbid>1245439719</clnt_dbid> <mydate>6/19/2009 15:28:39</mydate> <amount>33222112121.212000</amount> </px> <px class_id_reference="1" object_id="_4"> <otrq_prov_id>1245439719</otrq_prov_id> <clnt_dbid>1245439719</clnt_dbid> <mydate>6/19/2009 15:28:39</mydate> <amount>33222112121.212000</amount> </px> <px class_id_reference="1" object_id="_5"> <otrq_prov_id>1245439719</otrq_prov_id> <clnt_dbid>1245439719</clnt_dbid> <mydate>6/19/2009 15:28:39</mydate> <amount>33222112121.212000</amount> </px> <px class_id_reference="1" object_id="_6"> <otrq_prov_id>1245439719</otrq_prov_id> <clnt_dbid>1245439719</clnt_dbid> <mydate>6/19/2009 15:28:39</mydate> <amount>33222112121.212000</amount> </px> <px class_id_reference="1" object_id="_7"> <otrq_prov_id>1245439719</otrq_prov_id> <clnt_dbid>1245439719</clnt_dbid> <mydate>6/19/2009 15:28:39</mydate> <amount>33222112121.212000</amount> </px> <px class_id_reference="1" object_id="_8"> <otrq_prov_id>1245439719</otrq_prov_id> <clnt_dbid>1245439719</clnt_dbid> <mydate>6/19/2009 15:28:39</mydate> <amount>33222112121.212000</amount> </px> <px class_id_reference="1" object_id="_9"> <otrq_prov_id>1245439719</otrq_prov_id> <clnt_dbid>1245439719</clnt_dbid> <mydate>6/19/2009 15:28:39</mydate> <amount>33222112121.212000</amount> </px> </t> </boost_serialization> -- V S P toreason(a)fastmail.fm -- http://www.fastmail.fm - Send your email first class

Hi folks, Sorry for the confusion i've caused. It was a problem in my projects include-path, not with the include-path of gcc itself. I included files from another library i use, and this library contains a file named "assert.h" - why it was named so that it clashes with the system-assert i don't know. I renamed this file and altered it's #define include-guards. Now everything works. Thanks for reading my previous posts, I'm sorry for causing confusion with a problem that isn't boost-related at all.

I looked it up but can't find anything unusual: My include path reads as follows: C:/MinGW/bin/../libexec/gcc/mingw32/3.4.5/cc1.exe -E -quiet -v -iprefix C:\MinGW\bin\../lib/gcc/mingw32/3.4.5/ - ignoring nonexistent directory "C:/MinGW/bin/../lib/gcc/mingw32/3.4.5/../../../../mingw32/include" ignoring nonexistent directory "/mingw/lib/gcc/mingw32/3.4.5/../../../../mingw32/include" #include "..." search starts here: #include <...> search starts here: C:/MinGW/bin/../lib/gcc/mingw32/3.4.5/../../../../include C:/MinGW/bin/../lib/gcc/mingw32/3.4.5/include /mingw/lib/gcc/mingw32/3.4.5/../../../../include /mingw/include /mingw/lib/gcc/mingw32/3.4.5/include /mingw/include End of search list. And this is the assert.h: /* * assert.h * This file has no copyright assigned and is placed in the Public Domain. * This file is a part of the mingw-runtime package. * No warranty is given; refer to the file DISCLAIMER within the package. * * Define the assert macro for debug output. * */ /* We should be able to include this file multiple times to allow the assert macro to be enabled/disabled for different parts of code. So don't add a header guard. */ #ifndef RC_INVOKED /* All the headers include this file. */ #include <_mingw.h> #undef assert #ifdef __cplusplus extern "C" { #endif #ifdef NDEBUG /* * If not debugging, assert does nothing. */ #define assert(x) ((void)0) #else /* debugging enabled */ /* * CRTDLL nicely supplies a function which does the actual output and * call to abort. */ _CRTIMP void __cdecl __MINGW_NOTHROW _assert (const char*, const char*, int) __MINGW_ATTRIB_NORETURN; /* * Definition of the assert macro. */ #define assert(e) ((e) ?

Hello, from the reference at http://www.boost.org/doc/libs/1_39_0/libs/filesystem/doc/reference.html#Ope…: template <class Path> void remove(const Path& p, system::error_code & ec = singular ); Using the 1.39.0 release, on Windows MSVC9, I get the following error: 'boost::filesystem::remove' : no overloaded function takes 2 arguments Has the second argument been removed? Is there any form of the remove function that does not throw? Thanks, Dimitri

iostreams lzma filter support
by Olaf Peter 19 Jun '09

Hi, are there any plans to support the lzma algorithm by boost.iostreams filter? I've seen some japanese error messages by googling on this, but I did not find it inside the trunk. Is it self written? or any work in progress to make it public here? Thanks, Olaf

VS 2003 Wierd Linking Problem
by Dan Benčík 19 Jun '09

19 Jun '09

Dear all, I have installed boost according to the guide (http://www.boost.org/doc/libs/1_39_0/more/getting_started/windows.html) and have set the includes and libs directory accordingly (D:\Boost_1_38\lib for libraries and D:\Boost_1_38\ for includes). I try the basic code listed at point 4/ of the guide, but receive the following error: LINK : fatal error LNK1104: cannot open file 'D:\Boost_1_38\lib.obj' It seems, as if the VS put an empty name of an object file, attached it to the libraries directory and appended a .obj suffix. Could anybody help me out with this problem? Thank you, E.

[boost-users][asio] Connect with ssl to ipod?
by Germán Diago 19 Jun '09

19 Jun '09

Hello. I would like to know if it's possible (or there's any trick) to connect to ipod touch via boost.asio with ssl encryption. Currently I'm using an ssh connection with libssh. That's ok to navigate the directories, but I cannot copy files, since scp asks me for a password and I don't know how to solve this. Any idea? Thanks in advance.
