Did anyone run any benchmarks on boost compiled with icpc, the Intel compiler? -- yann(a)kierun.org -= H+ =- www.kierun.org PGP: 009D 7287 C4A7 FD4F 1680 06E4 F751 7006 9DE2 6318

Re: [Boost-users] Serialization using BOOST_CLASS_EXPORT_GUID
by Pavlo Korzhyk 28 Nov '07

28 Nov '07

When class is XXX_EXPORT-ed the code is generated for each included archive header. This is explained somewhere in the docs, probably near BOOST_CLASS_EXPORT macro description. So to avoid XML-related code generation don't #include unneeded archives Sincerely, Pavlo Korzhyk.

Are the boost libraries supported on any 64 bit platforms? In particular: Win64 and RedHat Linux 64. thanks, phil phystad(a)mac.com

for_each, mem_fun, bind1st with boost::ptr_vector?
by Robert Dailey 27 Nov '07

27 Nov '07

Hi, I can't figure out how to use std::mem_fun() and std::bind1st() with std::for_each() to call into a member function for each element in a boost::ptr_vector object. Some sample code below: class Object { public: void Tick( float number ) {} }; boost::ptr_vector<Object> m_objects; using namespace std; for_each( m_objects.begin(), m_objects.end(), bind1st( mem_fun( &Object::Tick ), 5 ) ); Of course, this doesn't compile at all. Can anyone tell me what I'm doing wrong?

boost with embedded compiler / in embedded area
by Bernhard Merkle 27 Nov '07

27 Nov '07

Hi, I have the following questions about using boost with embedded compilers / in the embedded area 1. what about embedded c++ compiler support in boost ? I saw on [1] some compilers but my list e.g. is - Metrowerks Codewarrior for PPC (v 8.x unfortunately) but the 9.x seems also to have problems - GreenHills C++ (seems to have the EDG parser, so no problem) - ARM C++ an they are not officially supported. Has anyone tried them or others ? experiences ? AFAIK, boost has some requirements to C++ compilers (especially templates) 2. what parts of boost are you using in your (embedded) area ? What parts would you avoid and what is recommendable ? (e.g. statechart, thread, the whole collection/algorithm things) Any performance/size issues ? TIA and kind regads, Berni [1] http://engineering.meta-comm.com/boost-regression/CVS-HEAD/developer/summar… <http://engineering.meta-comm.com/boost-regression/CVS-HEAD/developer/summar…>

conditional declaration of template class members
by Hicham Mouline 27 Nov '07

27 Nov '07

hi, Is it possible to define some member functions conditionally on integral template argument values? template <int n> class C { void f1(); void f2(); .... void f6(); // should be a member only if n==3 for e.g. }; I could specialize this template and then i would have to define f1..5() for both the general case and the special case(n==3). rds,

Serialization using BOOST_CLASS_EXPORT_GUID without XML
by Oliver Kania 27 Nov '07

27 Nov '07

Hello ! when using BOOST_CLASS_EXPORT_GUID, is there an option to disable implicit generation of XML-Archive code. I have quite a lot of serialization going on and want to save myself some headaches connected to XML archives. regards, Oliver

Problem with graphml

Hi Currently working on graphml reader so found a thread on http://article.gmane.org/gmane.comp.lib.boost.devel/146836 but when trying to access the attached file it is giving me error page stating "you are not authorized to view this page" Can i find the reader_test.cpp code on some other link so that i don't have to write the code again. Also i have downloaded graphml.cpp and graphml.hpp but when trying to compile the code it's giving me compilation error "C:/boost_1_34_1/libs/graph/src/graphml.cpp:22: error: expected `}' at end of input" in graphml.cpp file on the code "graphml_reader(mutate_graph& g):m_g(g), m_canonical_vertices(false) { }" What could be the reason for this..

Regarding lock-free data structure implementation in boost libraries
by Rakesh Sinha 26 Nov '07

26 Nov '07

Hi - I was just curious about some kind of lock-free data structure implementation (CAS algorithms specifically for Linux/GCC platform ) present in the boost library. After searching through the archives - I came across a Read-Writable lock that was later recalled. Can someone help me with some current status / point me to an appropriate API regarding the same. Thanks for the help.
