So maybe I can offer some advice, which may be of help when combined with some information from others. I would agree that if the library containing those functions is static, it should not export anything. It's difficult to cause anything to be exported (nearly impossible for C++ decorated names, IME) other than by decorating the declaration of that function or variable, or the class containing it. On VC++, the decoration appears at the beginning and takes the form __declspec(dllexport) To unravel the macros and conditional compilation, pass one of the files through the preprocessor only. Do this in Visual Studio by opening the properties window for just the one CPP file (not the project itself). Under C/C++, Command Line, add the "/E" option, without the quotes, where you can type Additional Options. Then right-click on the filename in the solution explorer and choose to compile just that file. It won't actually compile, but it will produce another text file (I forget where it puts it). Change it back before Visual Studio gets confused. If "dllimport" is in that text somewhere, it is indeed doing that on purpose.

error while loading shared libraries

Greetings all, I first created a class for a library like this: library.h: class Library { public: Library() { }; ~Library() { }; void testLib(); }; library.cpp: #include "library.h" #include <boost/thread/mutex.hpp> #include <boost/thread.hpp> #include <iostream> using namespace std; void Library::testLib() { boost::thread* lt; boost::mutex mu; boost::mutex::scoped_lock lock(mu); cout << "test!" << endl; } I then created the static library like so: g++ -I ~/boost_1_38_0/ -c library.cpp ar rcs libtest.a library.o and then I created a main.cpp like so: #include "library.h" #include <iostream> using namespace std; int main() { Library l; l.testLib(); } now when I try to compile main.cpp like this: $ g++ -I ~/boost_1_38_0/ -I. main.cpp -o main -L/usr/local/lib/ -L. -ltest -lboost_thread-gcc41- now when I run main: $ ./main ./main: error while loading shared libraries: libboost_thread-gcc41-mt-1_38.so.1.38.0: cannot open shared object file: No such file or directory I get that error.

unwanted exported symbols in a DLL which statically links to Boost.Library
by Luca Cappa 22 Apr '09

22 Apr '09

Hello, I am creating a DLL using the VisualC++ 8sp1, which statically links to Boost.Library, and also to another static library, which links to Boost.Library statically too. In the export section of the built DLL I see, among the few public functions which it should export, hundreds of exported functions like the ones below. I would really like to export the symbols the DLL defines as exported, and not anything else which is unexpectly exported, like the ones shown below: boost::archive::detail::oserializer<class boost::archive::xml_oarchive,struct sqy::Vector2<float> >::oserializer<class boost::archive::xml_oarchive,struct sqy::Vector2<float> >(void) boost::archive::detail::oserializer<class boost::archive::xml_oarchive,struct sqy::Vector2<float> >::oserializer<class boost::archive::xml_oarchive,struct sqy::Vector2<float> >(void) boost::archive::detail::oserializer<class boost::archive::xml_oarchive,struct sqy::Vector2<double> >::oserializer<class boost::archive::xml_oarchive,struct sqy::Vector2<double> >(void) In my static library, which statically link to the Boost.Serialization library, I have the following code which explicitly instantiate some template type on a set of a priori known datatypes: template MYLIB_API struct sqy::Vector2<int>; template MYLIB_API struct sqy::Vector2<float>; template MYLIB_API struct sqy::Vector2<double>; template MYLIB_API struct sqy::Vector2<size_t>; #define INSTANTIATE_VECTOR2_SERIALIZATION(x)\ template void MYLIB_API Vector2<x>::serialize<boost::archive::xml_oarchive> (\ boost::archive::xml_oarchive&, const unsigned int);\ template void MYLIB_API Vector2<x>::serialize<boost::archive::xml_iarchive> (\ boost::archive::xml_iarchive&, const unsigned int); INSTANTIATE_VECTOR2_SERIALIZATION(int); INSTANTIATE_VECTOR2_SERIALIZATION(float); INSTANTIATE_VECTOR2_SERIALIZATION(double); INSTANTIATE_VECTOR2_SERIALIZATION(size_t); Notice that, when the DLL is created, MYLIB_API is defined like # define MYLIB_API so i wonder where those symbols above comes from? Anyone could help me to remove from the DLL exporting section those unwanted symbols? Many thanks in advance, Luca

ptime on Win32?
by Del 22 Apr '09

22 Apr '09

Hi, I've been trying to use the boost local_time() function in a win32 program using mingw. After I inserted the call into my program, the program started to crash. So, I wrote a very simple test program: #include <iostream> #include <boost/date_time/posix_time/posix_time.hpp> using namespace boost::posix_time; int WinMain(HINSTANCE,HINSTANCE,LPSTR,int) { ptime time = microsec_clock::local_time();; std::cout << "The current time is " << time << std::endl; return 0; } It compiles and links fine, but when I run the program, I end up with this error message: This application has requested the Runtime to terminate it in an unusual way. Please contact the application's support team for more information. Any ideas?

Modifying Dijkstra's Shortest Paths algorithm in Boost::Graph to not relax certain edges
by Artyom 22 Apr '09

22 Apr '09

Hi, I am using Boost::Graph and DSP which comes with it to work out shortest paths around my graph. The problem is there is a certain exceptional situation when certain vertices can become unreachable along certain paths. I.e. although there is a valid distance value for edge B ? C, the same edge can become invalid if B is reached along a specific path. If this happens, I want DSP to reject that edge. I attempted to create a list of visitors. EdgeRelaxed records how vertices in the DSP queue were reached. EdgeExamined checks for the exceptional situation and if it's detected, it temporarily changes the distance value of the edge in question to infinity. EdgeNotRelaxed then restores the distance value to it's original. Unfortunately this approach doesn't seem to work, I think the reason for this is because dijkstras_shortest_paths() function gets information about distances from the weight_map which is passed to it. Is there any way I can modify the values inside the weight_map in between DSP stages to invalidate certain paths which will result in them being rejected for relaxation? Or perhaps there is an easier and tidier way of achieving the same result? Thanks in advance, Arty

Why must a Single Pass Range be default constructible?
by athor 22 Apr '09

22 Apr '09

A Range does not require copy semantics according to the boost docs. http://www.boost.org/doc/libs/1_38_0/libs/range/doc/range.html The SinglePassRangeConcept (and all range concepts using it) requires a range to be default constructible. (There is a line "T a;" in the concept The default constructible requirement means an abstract base class can never implement any Range Concept. If a range does not require any copy semantics, I don't see why it must be default constructible? Are there any good reasons I don't know about? A change from "T a;" to "const T& a" in concepts.hpp would do the trick... Example: struct AbstractArraySlice { int* begin() const = 0; int* end() const = 0; }; // FAILS: BOOST_CONCEPT_ASSERT((SinglePassRangeConcept<AbstractArraySlice>)) Footnote: I often use abstract base classes to verify my algorithms do not use more functionality than necessary and it annoys me that I can't use the range concept check: struct TestSum { const AbstractArraySlice& r; void Test() { CalculateSum(r); } }; template<class T> T CalculateSum(const T& range) <... function requires SinglePassRangeConcept ...> -- View this message in context: http://www.nabble.com/Why-must-a-Single-Pass-Range-be-default-constructible… Sent from the Boost - Users mailing list archive at Nabble.com.

Scoped_array with constructors?
by Space Ship Traveller 21 Apr '09

21 Apr '09

Hi, I want to use scoped_ptr with std::vector or scoped_array, but the problem is that the type I want to allocate has a non-trivial constructor. What is the standard way to make this work? My current best guess is to use std::vector with boost::scoped_ptr in the following way: TextureUnitsController::TextureUnitsController () { GLint textureUnitCount = 1; glGetIntegerv(GL_MAX_TEXTURE_UNITS, &textureUnitCount); m_textureUnits.resize(textureUnitCount); for (unsigned i = 0; i < textureUnitCount; i += 1) { m_textureUnits[i].reset(new TextureUnit(GL_TEXTURE0 + i)); } std::cerr << "Found " << textureUnitCount << " texture units..." << std::endl; } But this doesn't work because scoped_ptr also has a non-trivial constructor, so resize fails. Thanks Samuel

How to build boost for iPhone?
by Manfred Schwind 21 Apr '09

21 Apr '09

Hi, I tried to build boost for iPhone on Mac OS X. If I try the following ... bjam --prefix=/somePath toolset=darwin target-os=iphone macosx- version=iphone-2.0 define=_LITTLE_ENDIAN link=static install ... the libraries will build fine, but they are i386 code, not arm, so there're unusable. But if I add architecture=arm ... bjam --prefix=/somePath toolset=darwin architecture=arm target- os=iphone macosx-version=iphone-2.0 define=_LITTLE_ENDIAN link=static install ... the whole thing just does not build. It fails very early with the following error: g++-4.0: installation problem, cannot exec '/usr/bin/arm-apple-darwin9- g++-4.0.1': No such file or directory Any ideas/hints how to build the boost libraries for the iPhone? (By the way, /usr/bin/arm-apple-darwin9-g++-4.0.1 is existing on my Mac.)

Re: [Boost-users] boost variant compile time visitation: verification

Following my prev message, I wrote the following test on a win platform, compiled with VS2005 /O2 in release mode #include <iostream> #include <boost/variant/variant.hpp> #include <windows.h> typedef boost::variant<int, double, char> VT; struct print_type : public boost::static_visitor<const char*> { const char* operator()( int ) { return "int"; } const char* operator()( double ) { return "double"; } const char* operator()( char ) { return "char"; } }; int main() { const VT v('c'); LARGE_INTEGER usec0, usec1; const char* volatile res; QueryPerformanceCounter( &usec0 ); for(size_t s=0; s<2000000; ++s) res = v.apply_visitor( print_type() ); QueryPerformanceCounter( &usec1 ); std::cout<< (usec1.QuadPart - usec0.QuadPart) <<std::endl; QueryPerformanceCounter( &usec0 ); for(size_t s=0; s<2000000; ++s) res = "char"; QueryPerformanceCounter( &usec1 ); std::cout<< (usec1.QuadPart - usec0.QuadPart) <<std::endl; } There is no statistically significant difference between the 2 cases. Can I deduce that at least on this platform, for this code, the visitation is done at compile-time? Rds,

Why doesn't boost use empty throws() list?
by Joseph Garvin 21 Apr '09

21 Apr '09

For example, all the smart pointer headers have: // never throws Next to their definitions, rather than an actual "throws()". I'd guess this has to do with compiler compatibility, but there are already plenty of macro hacks for enabling/disabling details like this on a compiler by compiler basis. Just curious.

[Graph] How to get the key given a value in property_map
by Phani Deepak Parasuramuni 21 Apr '09

21 Apr '09

hi, i want to name the vertices and add the edges between vertices by referring to their names dynamicaly. i 'll have something like this. typedef boost::property<boost::vertex_name_t, string> VName; typedef boost::adjacency_list<boost::vecS, boost::vecS, boost::directedS, VName > Graph; typedef boost::property_map<Graph, boost::vertex_name_t>::type VertexNames; Graph g; VertexNames names = get(vertex_name, g); boost::add_vertex(VName("me") , g); boost::add_vertex(VName("myNeighbour") , g); i want to be able to do something like this. boost::add_edge( names.getKey("me"), names.getKey("myNeighbour") ,g); // but there is no any such kind of property_map i looked around and found that there are ways to get the name of vertex if i have a vertex_descriptor but how can i get a vertex_descriptor given the vertex_name there are only three ops defined on property_map :- get,put,iterator; is there any other way to get the key from value other than iterating through all the pairs in property_map & matching each pair.second with vertex_name? pardon me if it is a basic thing, i just cant able to get at it. Any help would be greatly appreciated. Thanks, Phani.

Blocking receive in message queue
by Johan Mazel 21 Apr '09

21 Apr '09

Hi I'm trying to use a message with a blocked (or timeout) receiver through the receive (or timed_receive) method(s). But the problem is that I can open the message once and then, I always get the "No such file or directory" message. It looks like the method can open the message queue on reading mode only once since each time that I launch it after, it ends right after the constructor of the message_queue object. I forced the program which send data on the message queue to be running through an infinite loop and I don't use a destructor on the message object inside the sending program. So I assume that the message_queue is still there. So, my question is : is there a real limitation which force me to open the message queue only one time in open_only mode ? Thanks in advance for the help. Johan Mazel

I'd like to have unique vertices in a graph based on index of type std::string.

No, it doesn't. Or I do something wrong. Regards liquid

boost variant compile time visitation: verification

Hello, #include <iostream> #include <boost/variant/variant.hpp> typedef boost::variant<int, double, char> VT; struct print_type : public boost::static_visitor<const char*> { const char* operator()( int ) { return "int"; } const char* operator()( double ) { return "double"; } const char* operator()( char ) { return "char"; } }; int main() { VT v('c'); std::cout<< v.apply_visitor( print_type() ) <<std::endl;; } If I understood the doc correctly, the visitation is supposed to be compile-time, that is, v.apply_visitor( print_type() ) is already "char" before the program start... Is this right? If so, is there a way to see this in the binary executable file? Maybe viewing symbols? I have access to vs2005 and g++3/4 /linux platforms. It would be so fantastic if compilers output _also_ the C++ source resulting from the template machinery! Best regards,

unordered_map serialization
by gtsml owevwr 21 Apr '09

21 Apr '09

Hi, I cannot find any serialization code for unordered_map in boost, am I missing something? I'm using boost 1.36, header <boost/unordered_map.hpp>. I could not find anything in 1.38 neither. Is the header <boost/serialization/hash_map> related? I have to say that I'm a bit confuse with the whole TR1 stuff (it seems to be related). Anyway, I can still convert to a list and serialize I guess, but if there's already something somewhere... Any suggestion welcome, Frank

[Boost-announce] Review Conclusion - Futures Library
by Tom Brinkman 21 Apr '09

21 Apr '09

Review Conclusion - Futures Library Braddock Gaskill http://braddock.com/~braddock/future Anthony Williams http://www.justsoftwaresolutions.co.uk/files/n2561_future.hpp The lack of examples and documentation made them difficult to review. Nevertheless, Anthony Williams futures library did receive almost unanimous and enthusiastic support. Unfortunately, the depth of the support was very shallow. I just finished my first read of Anthony's book "C++ Concurrency in Action and acknowledge his expertise in the areas of multi threaded and parallel programming. (http://www.manning.com/williams/) Anthony is the maintainer of boost::threads. Anthony's Future library has been approved for the next major release of c++ standard. Conclusion Braddock Gaskill - Rejected Anthony Williams - Approved Anthony's Futures library is approved for inclusion into boost::threads. As he is the maintainer of that library, he should be given maximum latitude about how that is to be done. In the future, if Anthony wants to re-publish the library as a top-level boost library, then he needs to resubmit it again with samples and test cases, which are lacking. Requirements As per the usual boost library requirements, examples and test cases are needed. Anthony should also improve the documentation, which should not be a problem as he is a prolific author in the area of multi threaded programming.

Hi all, I have encountered a runtime error when date_time tries to parse a time from a delimited string when compiled with intel c++ 11 in release mode. The following code is what I used to replicate the error: int main(int argc, char** argv) { using namespace boost::posix_time; ptime first = microsec_clock::local_time(); std::string temp = to_simple_string(first); ptime second = time_from_string(temp); // it crashes here } It works when using msvc9's compiler in debug and release mode and intel c++ 11 debug mode. Any idea how to resolve this? Thanks, Edward

[concept check][mpl] (Conditional) Concept checking for functions
by Jesse Perla 21 Apr '09

21 Apr '09

I have a variety of user defined function objects that I will need to call. Take the following examples:template<int N1, int N2 = 0> struct Func1{ double operator()(boost::array<double, N1>& x1, boost::array<double, N2>& x2){...}}; template<int N1> struct Func2{ double operator()(boost::array<double, N1>& x){...}}; With a function such as template<int N1, int N2 = 0, class F = boost::function<double (boost::array<double, N1>& x1, boost::array<double, N2>& x2)> class DPP{ void solve(){...... uses F...to be discussed} }; I have a few questions: 1) Is there a relatively easy way to use boost concept check to verify that F follows the first function signature so that I can detect compile time the problem? I can't figure out how to do it from the concept check docs, and they say they are out of date. Usage I want to check in the instantiation of DPP: F f; f(boost::array<double, N1>& x1, boost::array<double, N2>& x2) 2) I want the user to be able to pass in a simplified function type if N2 = 0 I assume that to call the actual function I would have some kind of impl function with partial specialization such as: template<bool use_simplified, int N1, int N2> struct use_f_impl(); template<int N1, int N2> struct use_f_impl<true, N1, N2>{ static double use_f() { STATIC_ASSERT(N2 == 0); F f; boost::array<double, N1> x; return f(x); } }; template<int N1, int N2> struct use_f_impl<false, N1, N2>{ static double use_f() { F f; boost::array<double, N1> x1; boost::array<double, N2> x2; return f(x1, x2); } }; And then in my solve() function I go: double val = use_f<(N2 == 0, N1, N2)>::use_f(); Is this the right idiom, pattern, etc? Do I need to use the struct with a static function since function templates don't have partial specialization? 3) Now what if I want to do a concept check on the F passed into DPP? It has to be conditional on the N2 value now. How would I do this? 4) Lets say that I don't want to force them to use the simplified version of the function signature if they don't want to. Can I automatically detect the signature and put it into a flag integer in the class? i.e. inside of the DPP class: static bool use_simple = IsSimple<F>::value; Then pass in the use_simple value when calling use_f_impl. If so, what would the IsSimple metafunction look like and can concept check help? Thanks, Jesse

[interprocess] 32 to 64 bit ?
by Stephan Menzel 20 Apr '09

20 Apr '09

Hi there, before holidays kick in I wondered whether I go for a strange problem in my usage of interprocess. Im using it within boost 1.38 on windows, msvc. Basically, I transfer data between two processes, which works great. So far, both have been built 32 bit release. But now since I exclusively use supposedly safe data types in the shared mem such as boost::uint32_t and friends I was wondering whether it's possible to have the data retrieving process built in 64 bit and access the same buffer. I just gave it a shot and it behaves different to what I had hoped for. In blocks during finding a struct with in a shared segment. ret = segment->find<struct my_buffer>(unique_instance).first; This operation blocks on a mutex in segment_manager.hpp: #ifdef BOOST_INTERPROCESS_RVALUE_REFERENCE scoped_lock<rmutex> #else detail::move_return<scoped_lock<rmutex> > #endif priv_get_lock(bool use_lock) { scoped_lock<rmutex> local(m_header, defer_lock); if(use_lock){ local.lock(); // <----- here! } return local; } .. never to return. The code is the same as in my 32 - 32 bit versions and known to work. Now I'm wondering, is this supposed to work or is 32 to 64 bit transfer not supported at all? Is this a bug or a feature? Do I have to have both applications in a 64 bit version? Cheers, Stephan

[repost][threads] recursive shared_mutex
by JOAQUIN M. LOPEZ MUÑOZ 20 Apr '09

20 Apr '09

Hi, allow me to repost this query of mine that went without much attention at first try... As the docs do not explicitly say otherwise, I guess I must assume that boost::shared_mutex is not recursive with respect to unique ownership, that is, the following behavior ensues: shared_mutex mutex; lock_guard<shared_mutex> lock1(mutex); lock_guard<shared_mutex> lock2(mutex); // DEADLOCK Is this so? In case boost::shared_mutex is indeed non-recursive, I've read the following assertion on Hinnant's paper N2406 (http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2007/n2406.html ): "A recursive shared mutex could be built upon shared_mutex if desired, but this is not proposed." Does anyone has a reference on how to construct a recursive shared_mutex from a non-recursive one? Thank you, Joaquín M López Muñoz Telefónica, Investigación y Desarrollo

Serialization of intrusive_ptr's?

Hey, quick question, what do I need to do to serialize intrusive_ptr's? I don't see anything in the serialization documentation to indicate that it supports it, does it? If not, is there an easy way? Or do I need to serialize the raw pointers and re-construct the intrusive_ptr's one by one? I'm storing intrusive_ptr's inside std container classes(map, list). Thanks, Jared

[serialization] deriving from xml_iarchive
by Kenny Riddile 20 Apr '09

20 Apr '09

I have a situation where I want an additional piece of data to be owned by the archive type we're using. Previously, I had this typedef that's used throughout our code: typedef boost::archive::xml_iarchive IutputArchive; I changed it to something like this: class InputArchive : public boost::archive::xml_iarchive { public: InputArchive( std::istream& is, Foo bar ) : boost::archive::xml_iarchive( is ) , m_bar( bar ) Foo GetFoo() const { return m_bar; } private: Foo m_bar; }; The problem I'm seeing is that whenever a serializable class's serialize() method is invoked via an InputArchive object, the template parameter to serialize() is instantiated with boost::archive::xml_iarchive, not InputArchive, which I need. Is it possible to get the behavior I want through public derivation like this, or is there a better way?
