[Build] System/integration testing?
by ajb＠spamcop.net 24 Nov '10

24 Nov '10

G'day. Boost.Build has fabulous facilities for unit testing, but I'm curious what is "best practice" for system testing. The simplest thing would be to run a shell script (portability isn't an issue here), passing it the path to all of the built binaries, but I'm sure someone must have already done something better than this. Thanks, Andrew Bromage

boost interprocess: memory allocation container

Hello, I am using boost 1.44 and trying to create shared memory and utilizing the segment manager with a interprocess map. I continually get a compile error when call the segment manager construct call. I can't figure out what the problem is. I have tried copy/paste example but continue to get the same error. "/usr/local/boost_1_44_0/boost/interprocess/detail/named_proxy.hpp:123:131: error: no matching function for call to 'forward(std::less<int>()&)' Below is the snippet of code: string driver_share = _cc.share_name + "_drivers"; using namespace boost::interprocess; //Clean up before creating shared memory shared_memory_object::remove(driver_share.c_str()); managed_shared_memory segment(create_only, driver_share.c_str(),65536); typedef boost::process::pid_type key_type; typedef boost::posix_time::ptime value_type; typedef std::pair<key_type, value_type> pair_type; typedef boost::interprocess::allocator<pair_type, managed_shared_memory::segment_manager> mem_allocator; typedef boost::interprocess::map<key_type, value_type, std::less<key_type>, mem_allocator> driver_map; const mem_allocator alloc_instance(segment.get_segment_manager()); driver_map *dmap = segment.construct<driver_map>("DriverMap")( std::less<int>(), alloc_instance); My include files are as follows: #include <boost/thread/thread.hpp> #include <boost/date_time/posix_time/posix_time_types.hpp> #include <boost/interprocess/managed_shared_memory.hpp> #include <boost/process/all.hpp> #include <boost/interprocess/allocators/allocator.hpp> #include <boost/interprocess/containers/map.hpp> #include <map> #include <functional> #include <iostream> using namespace boost; using namespace boost::posix_time; using namespace std; IF you know of any reason why I get this error that would be great.........I will continue to read the boost documentation.

[boost-users] [ptr_container] Genericity on containers
by Eloi Du Bois 23 Nov '10

23 Nov '10

Hi, I would like to know why is'nt that working: boost::ptr_vector<B> p1; boost::ptr_vector<B> p2; std::vector<B> v1; boost::ptr_vector<A, boost::view_clone_allocator> pview; // add elements... p1 = p2; pview = p1; // p1 = v1; // don't work // pview = v1; // don't work It should be working, or would be interesting to get working. Thank you, Eloi Du Bois.

Hi!

icc ULONG_MAX/UINT_MAX vs msvc ULONG_MAX/UINT_MAX
by Hai Nguyen 23 Nov '10

23 Nov '10

Hi, I'm running into a case where the Intel compiler is seeing mt19937 as: typedef random::mersenne_twister< unsigned long, 32, 624, 397, 31, 0x9908b0df, 11, 7, 0x9d2c5680, 15, 0xefc60000, 18, 3346425566U > mt19937; and MSVC is seeing it as: typedef random::mersenne_twister< unsigned int, 32, 624, 397, 31, 0x9908b0df, 11, 7, 0x9d2c5680, 15, 0xefc60000, 18, 3346425566U > mt19937; ...it's defined as: typedef random::mersenne_twister< uint32_t, 32, 624, 397, 31, 0x9908b0df, 11, 7, 0x9d2c5680, 15, 0xefc60000, 18, 3346425566U > mt19937; This is leading to a link time problem. I'm a bit lost as to what to do since the lib I'm depending on is compiled with the Intel compiler and my client program is using MSVC. >From my very brief look - it seems that uint32_t is controlled via ULONG_MAX and UINT_MAX - I was wondering if someone could shed some light on how the Intel compiler handles ULONG_MAX and UINT_MAX. I couldn't find its limits.h to figure out what it was doing. Also - is there a work around for cases like this? Thanks, Hai

BOOST_PROTO_EXTENDS_USING_ASSIGN
by Hossein Haeri 23 Nov '10

23 Nov '10

Dear all, When I compile the example right after http://beta.boost.org/doc/libs/1_45_0/doc/html/proto/users_guide.html#boost… I get the following error in GCC 4.5.0 (MinGW32, WinXPSP2): error: ISO C++ forbids declaration of 'BOOST_PROTO_EXTENDS_USING_ASSIGN' with no type error: expected ';' before 'typedef' I first thought that that's because I haven't included the right set of headers. Replaced them all with #include <boost/proto/proto.hpp> and the problem remains intact. Any suggestions? TIA, --Hossein

[Tuple] augment_tuple, patch, or whatever... maybe MPL?
by Hossein Haeri 23 Nov '10

23 Nov '10

Dear all, Is there any function in Boost.Tuple which works like this for n-tuples for any given n? template<typename T1, typename T2, typename T3> tuples::tuple<T1, T2, T3> augment_tuple(tuples::tuple<T1, T2> tup, T3 t3) { return tuples::make_tuple(tup.get<0>(), tup.get<1>(), t3); } (Obviously, here n == 2.) The purpose of this augment_tuple (or, patch, or whatever) is to take an n-tuple and a new element and patch the new element to the end of the n-tuple in order to get a (n + 1)-tuple. Repetitive code which can produce enough overloads for a large enough n is of course trivial. I'm wondering whether MPL has a utility which can automated this though? TIA, --Hossein

I have added a comment to the ticket. Is that sufficient? Sorry, I am not too familiar with how things work around here. Thanks, Edward

[Property-tree] Boost 1.45 with Intel Compiler + VS 2010 compile error
by Edward Rankin 23 Nov '10

23 Nov '10

Hi, I am trying to compile boost 1.45 using the recently released Intel Composer XE 2011 for Windows. I am running into the same error as described in ticker 4092 (https://svn.boost.org/trac/boost/ticket/4092) I have changed the check for BOOST_MSVC to include BOOST_INTEL_WIN (line 19 of boost/property_tree/detail/ptree_implementation.hpp) and can compile successfully. Not sure if this is the proper fix, so I hope the author/maintainer can look into this and fix this. Thanks! Edward
