typeof and ODR
by Arkadiy Vertleyb 18 Dec '04

18 Dec '04

Hi all, Does anybody have an access to an EDG-based compiler, and willing to help me to figure out whether a certain typeof test reports an ODR violation? I would very much appreciate this... Thanks in advance, Arkadiy

std::string <-> std::wstring conversion
by Stefan Slapeta 18 Dec '04

18 Dec '04

Hi all, there have been many discussions (and proposals) on this topic in the last years, but was there any result and is there _anything_ in boost today that can be used to convert between std::string and std::wstring? Stefan

I started to look at this in detail this afternoon. Using overload resolution to adjust to feature absence is an interesting technique, and new to me. But is it really needed? POSIX specifies a feature test macro, _POSIX_THREAD_SAFE_FUNCTIONS, which would seem to be sufficient. Was there a reason you didn't use it? Is it not reliable on some systems? Thanks, --Beman

It'd be trivial except that it interacts badly with Boost.MultiIndex safe mode. Let me think it over, I guess I can have something done after Xmas. Do you have the actual need to serialize iterators or is this more of an academic request? Have you tried the serialization capabilities in some compiler? Did you find any problem?

thread_pool
by Timothy Ritchey 17 Dec '04

17 Dec '04

I downloaded, and am getting ready to try out the thread_pool.zip implementation off the yahoo groups site by Dave Moore. I noticed that the file drop was dated 2002, and was wondering if there was a latest and greatest in the CVS tree, or whether I should use the implementation in the zip file. Cheers, tim

[signals] trackable not disconnecting
by Neal Coombes 17 Dec '04

17 Dec '04

I have been experiencing some strange behaviour (on Solaris 2.9 intel) with the signals::trackable object. I'm using it on all my objects that connect to signals and it doesn't seem to disconnect the signals consistently on destroyed objects (these objects are publicly and virtually derived from trackable). I've worked around the problem by manually disconnecting from all signals in the objects destructors. I'm having a very hard time making a small example program to demonstrate this behaviour (but I am working on it :). In the meantime if anyone else has experienced this kind of behaviour or has any information that might help, it would be greatly appreciated. TIA Neal

STLPort linking error
by Kenny Chamber 17 Dec '04

17 Dec '04

I am in the middle of moving our development from the std STL to STLPort and I am having a problem with two Athlon boxes. SuSE Linux 9.0 gcc 3.3.1 STLPort 4.6.2 Boost 1.31 I am changing an existing application to use STLPort and I have successfully completed the transition on a number of Intel boxes. When I try to build on an Athlon box I get the following error message: undefined reference to `boost::thread::thread[in-charge](boost::function0<void, std::allocator<boost::function_base> > const&)' I'm linking against libboost_thread-gcc-mt-p-1_31 and libboost_date_time-gcc-mt-p-1_31. I can't see an obvious solution so I'm hoping someone has solved this problem already. ----------------------- Kenny Chamber http://gem-hs.org/contact.html

[BGL] Patch for detail/adjacency_list.hpp
by Jürgen Hunold 17 Dec '04

17 Dec '04

Hi ! The last commit from Doug Gregor (Revision 1.130) broke compilation with gcc-3.4.1 for me. The attached patch fixes this by moving the implementation of remove_directed_edge_dispatch to a place _before_ it is used. Yours, Jürgen -- * Dipl.-Math. Jürgen Hunold !

*** PH.D. POSITION (GENERIC SOFTWARE LIBRARIES) *** Boost inside your Volvo?! In a joint project between Chalmers University and industrial partners from the automotive industry, there is an opening for a Ph.D. position specifically in the area of generic library design. The successful candidate will have the rare opportunity to earn a Ph.D. with a dissertation in which software is not just of "academic" value and interest, but really matters. Booster are encouraged to apply, to get back to me with recommendations, or to pass this advertisement on to others---this project is a big chance to implant generic programming in the (not just Swedish) car industry! Note that PhD positions in Sweden are regular jobs, with social benefits, paid vacation, parental leave, etc. I attach the entire announcement below; CEDES/4 is the position of interest.
