Cannot find regular expression symbols in Solaris debug
by phlasnicek 31 Jan '02

31 Jan '02

Hi, I am using Solaris Workshop 5.0 and I am using boost libraries for regular expressions. Everything builds fine and runs ok except when I try to attach to the process and run the debugger. I get the following error: warning: cannot demangle '__1c9uX__unnamed_6ofsRKVdR8zYNQre_get_error_str6FI_pkc_' Anyone have any suggestions, I would appreciate it very much. Thanks Paul

I've been using the ACE_Malloc framework from ACE (http://cs.wustl.edu/~schmidt/ACE.html) to solve a similar problem (sharing statics between DLL's). It takes a little while to figure out because the documentation is a little slim, but once you do it pays off pretty quickly. Doxygen documentation for ACE_Malloc is at: http://doc.ece.uci.edu/Doxygen/Current/html/ace/classACE__Malloc__T.html and the shared_mem memory pool is at: http://doc.ece.uci.edu/Doxygen/Current/html/ace/classACE__Shared__Memory__Po ol.html I ended up not having to write an STL allocator using ACE_Malloc, but I don't think it would be too difficult. If you get it right, a lot of ACE users would be your friend :) Tom Matelich > -----Original Message----- > From: xpav_2000 [mailto:alex@pavloff.net] > Sent: Tuesday, January 29, 2002 6:01 PM > To: Boost-Users(a)yahoogroups.com > Subject: [Boost-Users] Re: boost::pool + shared memory > > > --- In Boost-Users@y..., Tom Matelich <tmatelich@z...> wrote: > > Looks like pool may not be what I need, darn.

Hi John, that's what I'm doing now. I just want to fully understand the new jam way of building/using boost, and eg to see what is neccessary to use the 'new way'. Will the 'old way' be deprecated someday? Does/will the new way support static libs? > >And how to link the boost thread stuff? > >Is it supported for statically linked apps at all? > Build threadmon.cpp into a dll, and the rest of the source into a static > lib with the options you want. Okay, thanks, I will try this combination. bye, Bruno

It actually does slow things down noticeably, since it's a small project. > He might be sub setting boost and only wants to include the needed files. Exactly. I have 47 more files checked into source control that everybody else has to download (and have the tool check every time they refresh) so that I can parse a command line. I suppose I could check in the whole boost library, (~2000 files in the download I got,) but I'd rather just take what I need for now. > Anyway, this was brought up during the review, but at the time only 20 files > were needed (the very first tokenizer only need 2 boost headers).

Evidently reviewers thought 20 was reasonable, and I assume that some major problems are solved by the 47 headers that weren't by 20. I just wondered if there was a lighter weight way in boost to do my little tokenizing task. Is there? -- Tony K.

object_pool, O(N) destroy?
by kevin_godden＠agilent.com 29 Jan '02

29 Jan '02

Hi, I am considering using boost::object_pool for fast allocation and deallocation of likkle container/token objects. I need to make this as fast as possible, to this end I wonder why object_pool seems to use boost::pool::ordered_free() (O(N)) rather than the faster free() (O(1))? There must be a reason, but I can't seem to find it in the Lib's documentation. I would be interested in hearing if peoples experiences/comments on using object_pool. Thanks for reading! Kevin\

I agree, it does sound like a job for a Policy whatsit. If I get a chance I could try a few things and see if anything works out and let you know. Although, if time constraints work out the way I think they will, I might have to stick with a cut&paste solution!

Actually, the difference is in how the pool is used, not on the type of object being allocated. So it sounds more like a case for a policy-based design. Too bad, I just don't have time to do that right now... :( -Steve Info: <http://www.boost.org> Wiki: <http://www.crystalclearsoftware.com/cgi-bin/boost_wiki/wiki.pl> Unsubscribe: <mailto:boost-users-unsubscribe@yahoogroups.com> Your use of Yahoo!
