problem with boost units
by Robert Ramey 23 Sep '15

23 Sep '15

the following small example fails to compile and points to error in assignment. For the life of me I can't figure why this should fail. Any help appreciated. Robert Ramey // include headers to implement output operations for quantities with units #include <iostream> #include <boost/units/io.hpp> #include <boost/units/systems/si/volume.hpp> int main(){ boost::units::si::volume fuel_capacity; fuel_capacity = 9.0f * boost::units::si::cubic_meters; ------------------^ std::cout << " " << fuel_capacity << "\n"; return 0; }

boost::interprocess mapped_file binary compatibility
by Vladimir Kotlyar 17 Sep '15

17 Sep '15

What, if anything, can be assumed about cross-platform and backwards binary compatibility of files generated using boost::ipc classes? I could not find any explicit statement in the IPC library docs. Thanks. -- View this message in context: http://boost.2283326.n4.nabble.com/boost-interprocess-mapped-file-binary-co… Sent from the Boost - Users mailing list archive at Nabble.com.

Problems with boost::coroutines with lambda captures
by Mikhail Strelnikov 17 Sep '15

17 Sep '15

> Sumamry: somehow the captured smart pointer gets destroyed+corrupted > when I yield from the coroutine, but the local copy survives. When I use GeneratorBlockEnumerator gets parameter (std::function) by value (temporary function gets created before constructor and destroyed right after). Then this temporary function passed by reference to push_type.

[Interprocess] Compiling unordered_map in shared memory on GCC 4.1.2
by Karyakin, Maxim 16 Sep '15

16 Sep '15

Hi all, I'm having issues compiling boost::unordered_map with boost::interprocess. I'm using boost 1.57 and compiler is GCC 4.1.2 . I've tried to ask it on SO few months ago, but got no solution for it and decided to use just map. Now I'm seeking for some performance improvement again, so I will try my luck here. I took code from the answer on SO (http://stackoverflow.com/questions/29557680/boost-interprocess-unordered-ma…) with minimal changes to make it work under non C++11 compiler. It looks better than my and there are same errors generated. Code: #include <boost/interprocess/managed_shared_memory.hpp> #include <boost/interprocess/containers/string.hpp> #include <boost/interprocess/containers/map.hpp> #include <boost/unordered_map.hpp> namespace bip = boost::interprocess; // ShmString is boost::interprocess::basic_string typedef bip::allocator<char, bip::managed_shared_memory::segment_manager> CharAllocator; typedef bip::basic_string<char, std::char_traits<char>, CharAllocator> ShmString; typedef ShmString HashKeyType; // ComplexType is a wrapper for internal interprocess::map struct ComplexType { typedef bip::allocator<std::pair<int const, int>, bip::managed_shared_memory::segment_manager> Alloc; typedef bip::map<int, int, std::less<int>, Alloc> Map; template <typename Alloc2> ComplexType(std::string, Alloc2 const& alloc) : map(alloc) {} Map map; }; typedef ComplexType HashMappedType; typedef std::pair<const ShmString, ComplexType> HashValueType; typedef bip::allocator<HashValueType, bip::managed_shared_memory::segment_manager> HashMemAllocator; typedef boost::unordered_map<HashKeyType, HashMappedType, boost::hash<HashKeyType>, std::equal_to<HashKeyType>, HashMemAllocator> TestHashMap; int main() { // Allocation: { bip::managed_shared_memory segment(bip::open_or_create, "MySharedMemory", 65536); TestHashMap * thm_ = segment.construct<TestHashMap>("TestHashMap")(3, boost::hash<ShmString>(), std::equal_to<ShmString>(), segment.get_allocator<HashValueType>()); } // Usage: bip::managed_shared_memory segment(bip::open_only, "MySharedMemory"); TestHashMap * thm_ = segment.construct<TestHashMap>("TestHashMap")(3, boost::hash<ShmString>(), std::equal_to<ShmString>(), segment.get_allocator<HashValueType>()); ShmString str("123.345", segment.get_allocator<ShmString>()); ComplexType th("MySharedMemory", segment.get_segment_manager()); HashValueType value(str, th); thm_->insert(value); } And here is some error output:

[boost] integrating NaCl support into boost
by Konstantin Ivlev 16 Sep '15

16 Sep '15

Hi boost community, how about integrating NaCl support patches into the boost main-line (trunk/master), I am talking about these NaCl ports patches: https://chromium.googlesource.com/external/naclports/+/master/ports/boost (I actually have a bit more correct patches that allow to compile boost 1.59 for NaCl platforms, while Google patches are still for 1.55). I would be grateful to hear suggestion about how to process with it, e.g. which actions should I take to make it really happen. I personally suppose making boost to officially support more platforms will make boost more popular and allow more developers to use it and port their applications to other platforms. I look forward to hearing from you soon. yours sincerely, Konstantin

bimap broken in 1.59 on mac?
by James Sutherland 15 Sep '15

15 Sep '15

I have been using boost::bimap for quite some time, and in 1.59 I am seeing numerous compiler errors that terminate with: BIMAP_STATIC_ERROR__const_local_iterator_type_by_FAILURE I have no idea what is causing this, and a google search doesn't turn up anything either. Has anyone seen this? COMPILER: Apple LLVM version 6.1.0 (clang-602.0.53) (based on LLVM 3.6.0svn) Target: x86_64-apple-darwin14.5.0 Here is a simple code to generate the problem: //---------- #include <boost/bimap.hpp> #include <iostream> int main() { typedef boost::bimap< int, double > MyMapT; MyMapT map; int i1=3; double d1=3.333; map.left .insert( MyMapT::left_value_type ( i1, d1 ) ); MyMapT::left_iterator il = map.left .find( i1 ); MyMapT::right_iterator ir = map.right.find( d1 ); std::cout << ir->second << " <-> " << il->second << std::endl; } //---------- Thanks for any tips, James
