[serialization] Clearing Intel/Windows errors?
by Beman Dawes 04 Dec '07

04 Dec '07

A whole bunch of serialization tests are failing for Intel/Windows because of an apparent error in export.hpp. See below. What is the status of getting this fixed? ..\boost/serialization/export.hpp(131): error: redeclaration cannot add dllexport/dllimport to "boost::archive::detail::ptr_serialization_support<Archive, Serializable>::instantiate" (declared at line 131) BOOST_DLLEXPORT void ptr_serialization_support<Archive,Serializable>::instantiate() Thanks, --Beman

C++ Performance

Hi everybody Im a quite new boost user and I wonder, why C++ Program is so slow. I wrote a program, and I have the same program in Matlab, I expected that my C++ version is much faster, but its not. I use matrices, vectors, matrix- and vector proxies. Do some solving and compute calculations with prod, element_div, etc.. Is boost in general slower than matlab, should I use something else? Id be real happy about any help.

I suspect I may not be first or last person to do this :-) Could the source file usefully have a comment that says something like " If you get a error "'const_iterator' : is not a member of 'std::ios_base'" here have you typed "end;" somewhere instead of "endl;" " ?

[hdstl] Status and future plans?
by Staffan Gimåker 04 Dec '07

04 Dec '07

Hello list, I recently found myself in need to use a half-edge datastructure for doing Delaunay triangulation. Rather than rolling my own half-assed classes, I thought I'd see what the recent GSoC project on the topic had to offer. I've only glanced through the sources, but it certainly looks nice. However, before spending more effort on it it'd be nice to know its current status and what the future has in store for it. From http://tinyurl.com/283gm2 I gather that its mostly complete, but that's also pretty much information I could find, except for the sources. Are there plans on submitting the library for review, and if so, in what timeframe? I'd really like to see something like this make it into Boost, it's a shame to see that it's been 4 months since the code was changed. Staffan Gimåker

units: need limits
by Noah Roberts 03 Dec '07

03 Dec '07

std::numeric_limits needs to be implemented for quantity. I think this should work: namespace std { template< typename T, typename U > class numeric_limits< boost::units::quantity<U, T> > : public numeric_limits<T> { typedef numeric_limits<T> type_limits; typedef boost::units::quantity<U, T> qty; public: static qty denorm_min() { return qty(type_limits::denorm_min() * U()); } static qty epsilon() { return qty(type_limits::epsilon() * U()); } static qty infinity() { return qty(type_limits::infinity() * U()); } static qty max() { return qty(type_limits::max() * U()); } static qty min() { return qty(type_limits::min() * U()); } static qty round_error() { return qty(type_limits::round_error() * U()); } static qty quiet_NaN() { return qty(type_limits::quiet_NaN() * U()); } static qty signalizing_NaN() { return qty(type_limits::signaling_NaN() * U()); } }; }

BOOST_LOCAL_FUNCTION
by Alexander Nasonov 03 Dec '07

03 Dec '07

After few months of inactivity I came back to a local function syntax. Instead of trying to bind local variables, I implemented a couple of macros that simply assign a value to a function pointer: int BOOST_LOCAL_FUNCTION(char c) { std::cout << c << '\n'; return 1; } BOOST_LOCAL_FUNCTION_DECL(a) a('A'); // output: // A This code defines int (*a)(char) and assigns to it a pointer to the body of local function shown above. Half-preprocessed output is int (*sig16)() = 0; typedef struct { static BOOST_TYPEOF(sig16()) body(char c) { std::cout << c << '\n'; return 1; } } local20; BOOST_AUTO(a, &local20::body); a('A'); It's also possible to assign a pointer to any object compartible with int (*) (char): boost::function<int(char)> zz; int BOOST_LOCAL_FUNCTION(char c) { std::cout << c << c << '\n'; return 2; } BOOST_LOCAL_FUNCTION_ASSIGN(zz) zz('Z'); // output: // ZZ Proof of concept code is in the end of this message. Currently, it doesn't handle void return (Boost.Typeof limitation) and doesn't compile when arguments or return type is a dependant name. gcc 3.4 often crashes on local function defined inside templates. #include <iostream> #include <boost/function.hpp> #include <boost/typeof/typeof.hpp> #define BOOST_LOCAL_FUNCTION (*BOOST_PP_CAT(sig,__LINE__))() = 0; \ typedef struct { static BOOST_TYPEOF(BOOST_PP_CAT(sig,__LINE__)()) body #define BOOST_LOCAL_FUNCTION_ASSIGN(f) } BOOST_PP_CAT(local,__LINE__); \ f = &BOOST_PP_CAT(local,__LINE__)::body; #define BOOST_LOCAL_FUNCTION_DECL(f) } BOOST_PP_CAT(local,__LINE__); \ BOOST_AUTO(f, &BOOST_PP_CAT(local,__LINE__)::body); int main() { int BOOST_LOCAL_FUNCTION(char c) { std::cout << c << '\n'; return 1; } BOOST_LOCAL_FUNCTION_DECL(a) a('A'); boost::function<int(char)> zz; int BOOST_LOCAL_FUNCTION(char c) { std::cout << c << c << '\n'; return 2; } BOOST_LOCAL_FUNCTION_ASSIGN(zz) zz('Z'); }

[pool] Is it even possible to call release_memory() for map/list allocator pools portably?
by Scott 03 Dec '07

03 Dec '07

I have a map, declared as: typedef std::pair<int, HintPage *> PageCachePair; typedef boost::fast_pool_allocator<PageCachePair> PageCacheAllocator; typedef std::map<int, HintPage *, std::less<int>, PageCacheAllocator> PageCache; The problem is when I try to call: boost::singleton_pool<boost::fast_pool_allocator_tag, sizeof(PageCachePair)>::purge_memory(); This always returns false. The real problem (of course) is that sizeof(PageCachePair) is incorrect. The real size is determined by the rebind mechanism for the actual map node struct. However, I have no idea how to portably determine that size. Is it even possible to do this? Scott

[python] gcc-warnings
by Juergen Hunold 03 Dec '07

03 Dec '07

Hi ! I'm experimenting with the Boost.Python bindings and get the warning: boost/python/detail/unwind_type.hpp:152: warning: unused parameter 'p' when building my extension library with gcc. Full output "errort.txt" attached. My gcc is: gcc -v gcc version 4.1.2 (Ubuntu 4.1.2-0ubuntu4) The attached patch "unwind_type.hpp.diff" fixes the problem for the "not msvc" case. All Boost.Python tests pass. The interesting thing is that this warning is not produced by _any_ of the existing test case. Question: Ok to commit ? Yours, Jürgen -- * Dipl.-Math. Jürgen Hunold !
