Some strange boost headers errors
by alfonso santimone 15 May '15

15 May '15

Hi guys, i'm a boost newbie. I've got to include boost libraries in the include path of a VisualStudio 2012 project. When i try to compile i have all these errors. Every errors is related to missing headers ( boost ones and even standard Win ones ) and to synthax errors depending on missing headers i guess. Do someone have any idea on what's wrong here? I just post here a few lines of errors, but the other ones are all of the same kind Error 1 error C2061: syntax error : identifier 'boost' C:\boost_1_57_0\boost\core\ checked_delete.hpp 24 1 csound~ Error 2 error C2059: syntax error : ';' C:\boost_1_57_0\boost\core\checked_delete.hpp 24 1 csound~ Error 3 error C2449: found '{' at file scope (missing function header?)

[flyweights] private constructor, friend access
by r＠primef.actor 15 May '15

15 May '15

Dear all, On a project of mine, I started to use Boost.Flyweight. I would like users of my class to only be able to instantiate objects of my class by using the Boost.Flyweight mechanism. For this, I make my class constructor private. However, when doing so the corresponding flyweight factory also cannot instantiate my class. What classes do I need to `friend` in order to make this work? Here's a small self-contained example of the problem: class X { public: int data() const { return m_data; } struct key_extractor { int operator()(const X& x) const { return x.data(); } } typedef boost::flyweights::flyweight < boost::flyweights::keyvalue < int, X, key_extractor > > flyweight; private: int m_data; X(int x) : m_data(x) {} // friend declarations should go here }; int main() { auto my_x = X::flyweight(42); return 0; } Kind regards, Raoul Wols

Managed shared memory size restrictions
by Veranika Liaukevich 14 May '15

14 May '15

Hello everybody, Is there any restriction to the size of managed shared memory regions? Should it be in multiples of the page size? I did not manage to find any relevant information in the documentation, but managed_shared_memory creation and managed_shared_memory::grow sometimes fail with small memory sizes specified. Examples: 1) When I create a managed_shared_memory segment with size 40, the creation fails with interprocess_exception::library_error. 2) I created managed_shared_memory with initial size 1000, then increased the size by 24 bytes, I got this: /usr/include/boost/interprocess/mem_algo/rbtree_best_fit.hpp:514: void boost::interprocess::rbtree_best_fit<MutexFamily, VoidMutex, MemAlignment>::grow(boost::interprocess::rbtree_best_fit<MutexFamily, VoidMutex, MemAlignment>::size_type) [with MutexFamily = boost::interprocess::mutex_family; VoidPointer = boost::interprocess::offset_ptr<void>; long unsigned int MemAlignment = 0ul; boost::interprocess::rbtree_best_fit<MutexFamily, VoidMutex, MemAlignment>::size_type = long unsigned int]: Assertion `new_block->m_size >= BlockCtrlUnits' failed. Aborted (core dumped) I use boost 1.55.0 on Ubuntu 14.04 64bit. Code used for testing: #include <boost/interprocess/managed_shared_memory.hpp> const char *shmname = "MyBoostShmTest"; // Usage: ./progname [init-memory-size] [grow-memory-size] int main(int argc, char **argv) { using namespace boost::interprocess; struct shm_remove { shm_remove() { shared_memory_object::remove(shmname); } ~shm_remove(){ shared_memory_object::remove(shmname); } } remover; size_t size = atoi(argv[1]); size_t grow_size = atoi(argv[2]); { managed_shared_memory segment(create_only, shmname, size); } { managed_shared_memory::grow(shmname, grow_size); } return 0; } Thanks, Veranika

[bccl] how to use predefined concepts to restrict a template argument via sfinae
by Nick Stokes 13 May '15

13 May '15

The use case is from Boost Graph, but my question is a general one about Boost Concept Check Library: How to "restrict" a template class/function argument based on concepts. For instance, I want to overload functions based on Graph or VertexListGraph or similar refinement. template<class VertexListGraph, XXX > void foo( VertexListGraph& g ) {...} where XXX is somekind of SFINAE that leverages boost::VertexListGraphConcept. Thanks, Nick

[BGL] pull requests?
by Mads Jensen 13 May '15

13 May '15

Hi, I don't know if this is the right list to send this to. However, there is a fair amount of trivial pull requests for the Boost Graph Library. Most of which address small errors in the documentation. There hasn't been any activity in that repository since August last year. Can someone with write access please have a look at it? -- Med venlig hilsen / Kind regards, Mads Jensen Life holds no terrors when you have embraced the philosophy of flipism! -- Carl Barks (Walt Disney Comics & Stories 149)

Boost.Coroutine Debian package
by Konrad Zemek 13 May '15

13 May '15

Hey everyone, I have asked this question the person who introduced Boost.Coroutine in the Debian package (control files can be found in debian svn repository [1]) a few days ago but have not received a reply: Does anyone happen to know why - for Debian package - Boost.Coroutine is built as a static library only? Our project prefers dynamic linking, and we also need -fPIC since we're building shared libraries as well, yet Boost.Coroutine is one of two libraries (the other one being Boost.Exception) built only as a non-fPIC static version. I have modified the control files to enable building libboost_coroutine.so, and we're currently using it for our project seemingly without any problem, but it worries me that there must have been a reason for the special treatment of Boost.Coroutine package. And a "by the way" question if anyone happens to know, I'm curious why Debian unstable still provides Boost 1.55 as the newest version? [1] svn://anonscm.debian.org/pkg-boost/boost Konrad

Re: [Boost-users] boost::intrusive::slist push_back() => error: static assertion failed:
by Jonas Printzén 11 May '15

Mail-list failed to send me the reply from Ion, attempting a reply anyways... *(mail-list owner, what i do wrong?)* Thanx Ion. I got it to work as you suggested. Found old gtest - loggs that confirmed that the cache_last option wasn't needed in old code so this must be a change . Oh, and yes. uint64_t... :-) .. yes I modified the code after cut-paste. The docs for 1.55 intrusive slist under "Using base hooks <http://www.boost.org/doc/libs/1_55_0/doc/html/intrusive/usage.html#intrusiv…>" shows example with push_back() without mentioning cache_last. Mabey it should be push_front() in that example? Nifty to get to pick and choose level of overhead :-) /Jonas
